Frequently Asked Questions - 58336 TORO

How do I start the Toro 58336 tiller?

Ensure the drive clutch control is released. Move the throttle lever to FAST. If starting a cold engine, pull the choke valve out to full choke. Pull the recoil starter handle until you feel engagement, then pull vigorously. Once started, adjust choke as the engine warms.

What type of oil should I use for the crankcase?

Use high-quality detergent oil with API service classification MS, SC, SD, or SE. For summer (above 40°F/4°C), use SAE 30 or 10W-40. For winter (below 40°F/4°C), use SAE 10W or 5W-30. Capacity is 20 ounces (0.591 L).

How do I adjust the tilling depth?

Use the wheel adjusting lever. Raising the wheels increases tilling depth, lowering them reduces depth. The drag stake also helps control depth by retarding forward movement. Adjust to achieve the desired soil penetration.

What maintenance is required after every 25 hours of use?

Change the crankcase oil, clean the air cleaner element, check and adjust spark plug gap (0.030 in / 0.76 mm), and inspect the drive belt tension. Also lubricate wheel bushings and idler pulley.

Can I use the tiller in wet soil?

No, not recommended. Wet soil can ball up, stick to tines, and cause mechanical damage. It also dries into hard lumps. Only till when soil is dry enough to crumble by hand.

How do I change the width of swath?

Remove the two outboard tine sections by pulling out the cotter pins and clevis pins. This adjusts the swath from 22 inches (maximum) down to 11 inches (minimum).

What should I do if the tines do not rotate?

Check the drive belt for breakage or incorrect tension. To adjust belt tension, move the spring on the idler pulley arm one link at a time until tines engage when the clutch control is squeezed. If broken, replace the belt.

Is it safe to operate the tiller on slopes?

The manual does not specify slope operation. General safety: maintain secure footing and balance. Avoid operating on steep slopes where the tiller could tip or become uncontrollable.

How do I prepare the tiller for winter storage?

Drain the fuel tank and run the engine until it stops. Remove the spark plug, pour 2 tablespoons of oil into the cylinder, and pull the recoil starter slowly. Drain and change oil, clean all parts, lubricate pivot points, and touch up paint. Do not reinstall the spark plug wire.

Where can I find replacement parts for the Toro 58336?

Contact an Authorized TORO Service Dealer or Distributor. Refer to the Yellow Pages. Use only genuine TORO replacement parts. The model and serial number decal is located on the rear of the chain drive case.

PREPARATION BEFORE STARTING

FILL CRANKCASE WITH OIL

Tools Required: Pliers, Clean Rag, Funnel and Oil Tube (provided)

IMPORTANT: The tiller is shipped from the factory without oil in the crankcase. Before starting engine, crankcase must be filled to the proper level with recommended oil.

IMPORTANT: Check level of oil every 5 operating hours or each time tiller is used. Initially, change oil after the first 2 hours of operation; thereafter, under normal conditions, change oil after every 25 hours of operation. Change oil more frequently when engine is operated in only dusty or dirty conditions.

1. Move tiller to a level surface to assure accurate oil level reading.
2. Clean the area around the oil filler plug so foreign matter cannot enter filler hole when plug is removed.

3. Remove filler plug from crankcase (Fig. 4).

4. Slowly, pour approximately 20 ounces (.591 l) of oil into crankcase using provided oil tube with funnel (Fig. 4). The Briggs & Stratton engine uses any high quality detergent oil having the American Petroleum Institute — API — “service classification” MS, SC, SD, or SE. Oil viscosity — weight — must be selected according to the season’s ambient temperature.

A. Summer (over 40°F, 4°C) Use S.A.E. 30 or 10W-40 oil.
B. Winter (below 40^ F, 4^ C) — Use S.A.E. 10W or 5W-30 oil.

Figure 4 Filling Crankcase With Oil

1. After crankcase is filled with oil, rock the tiller gently to release any air that may be trapped in the crankcase. If level of oil drops, add enough to bring it up to the point of overflowing.
2. Install filler plug into opening in crankcase. Wipe up any oil that may have spilled.

FILL FUEL TANK WITH GASOLINE

Tools Required: Clean Rag and Funnel with Filter

Always use clean, fresh gasoline. If gasoline is allowed to stand it will form gum-like varnish deposits in the carburetor, fuel line, and fuel tank. Such deposits cause starting problems and poor engine operation.

IMPORTANT: Do not mix oil w/gasoline because engine damage and poor performance may result. Do not use premium gas, gasohol, white gas or gasoline additives. Either leaded-regular or low lead gasoline is acceptable to fill the 2 quart (1.88 l) fuel tank.

DANGER

Because gasoline is flammable, caution must be used when storing or handling it. Do not fill fuel tank while engine is running, hot or when machine is in an enclosed area. Vapors may build up and be ignited by a spark or flame source many feet away. DO NOT SMOKE while filling the fuel tank to prevent the possibility of an explosion. Always fill fuel tank outside and wipe up any spilled gasoline before starting engine. Use a funnel or spout to prevent spilling gasoline, and fill tank to about 1/2 inch (12.7 mm) below the filler neck. Store gasoline in a clean safety-approved container and keep the cap in place on the container. Keep gasoline in a cool, well-ventilated place; never in an enclosed area such as a hot storage shed. To assure volatility, do not buy more than a 30 day supply of gasoline. Gasoline is a fuel for internal combustion engines; therefore, do not use it for any other purpose. Since many children like the smell of gas, keep it out of their reach because the fumes are explosive and dangerous to inhale.

PREPARATION BEFORE STARTING

1. Clean area around the fuel tank cap so foreign matter cannot enter the tank when cap is removed.
2. Remove cap from fuel tank and fill tank with leaded regular or low lead gasoline. Then install fuel tank cap.
3. Wipe up any gasoline that may have spilled while tank was being filled.

CHAIN DRIVE CASE

The chain drive case comes filled with oil. It is not necessary to fill chain drive case unless shipping carton shows evidence that oil has leaked out: Refer to Filling Chain Drive Case, page 17.

Under normal operating conditions the chain drive case need only be checked once a year to make sure oil level is maintained. However, if there is evidence of oil leaking from the chain case or bearings, check oil level more frequently. If oil leaks persist contact your nearest Authorized TORO Service Dealer.

CONTROLS

Drive Clutch Control (Fig. 5) — Clutch control is mounted near the left handle grip. By squeezing control against handle, pivoting idler pulley is pulled against a V-belt; thus, forward tine engagement results. To maintain tine engagement, squeeze clutch control continuously or depress locking pin and release control against pin. Squeeze clutch control against handle, which will disengage locking pin, and allow control to release: Tines and forward movement will stop.

CAUTION

To stop engine quickly in an emergency, release (disengage) drive clutch control and move throttle lever to the STOP position.

OPERATING INSTRUCTIONS

BREAK-IN

The engine requires no special break-in other than changing crankcase oil after the first two hours of operation. Operate the tines to make sure that drive system is functioning correctly. After the first five hours of operation, check condition of belt and check for possible loosening of any nuts, bolts, and screws.

DRAG STAKE

Drag Stake (Fig. 14 and 15) — When the drag stake engages the soil, it forces the tines into the soil and eases operator effort in controlling forward advance and overall control of the tiller. When tiller is pulled backward, drag stake will pivot forward so movement is not adversely affected.

OPERATING INSTRUCTIONS

Tilling (Engaged) Position:

1. Rotate locking channel so that the drag stake is free to rotate down to tilling position (Fig. 14).

Figure 14 Tilling Position

Transport Position:

1. After tilling, move drag stake forward and rotate locking channel to hold drag stake in transport position (Fig. 15).

Figure 15 Storage and Transport Position

ADJUSTING WHEELS

Wheels on the tiller can be raised or lowered to govern forward speed of the tiller and depth of tilling. To adjust, proceed as follows:

1. Move adjusting lever upward (Fig. 16). Raise or lower the wheels to the desired position, then

Figure 16 Adjusting Wheels

lock wheels in position by depressing adjusting lever. Ground conditions vary greatly, and you will have to experiment with degree of adjustment until you get satisfactory results.

1. Wheels will ride on the ground once tilling begins.

2. After tilling, wheels can be adjusted again for transporting tiller.

CHANGING WIDTH OF SWATH

1. The width of swath is adjustable from 11 to 22 inches (.305 m to .559 m) by removing the two (2) outboard tine sections. To remove tine sections, remove cotter pins and clevis pins; then slide tine sections off inboard tines (Fig. 17 and 18).

OPERATING INSTRUCTIONS

USING THE TILLER

The tiller is a multiple-use, soil conditioning product. It can be used to renovate a garden, flowerbed or lawn. Soil "conditioning" occurs when the soil is blended, mixed, aerated or pulverized by the rotation of the tines. Two or more passes may be required to condition soil properly; however, different types of soil will affect the total working time. Wet soil tends to ball up, stick to the tines, and may result in poor conditioning. Wet, tilled soil may dry into rock-like lumps with a hard crusty cover. This condition is not conducive to seed germination and plant growth. Wet soil may plaster onto the tine rotor, resulting in reduced penetration when tilling. In addition, any abnormal buildup of soil on the belts may cause mechanical damage. Therefore, use the tiller only when the ground is "dry" (when soil may be crumbled with the hand), and wash tiller after use to remove any accumulated dirt and vegetation.

Generally, there are three types of soil conditioning applications:

1. Breaking up untilled soil.
2. Conditioning soil that has previously been tilled.
3. Cultivating.

Before starting the engine, engage the drag stake, and adjust wheels to the desired position. The penetrating drag stake tends to retard forward movement of the tiller, thus making it easier to control. When breaking up untilled soil run engine at maximum speed. To prevent fatigue of the left hand, use the locking pin to hold drive clutch control in the engaged position.

CAUTION

Clutch control locking pin should not be used when tilling in confined areas or near fences.

Initially, untilled soil and grass are broken apart by pressing down on the handles to produce slow forward movement and maximum rotation of the tines; and it may even be necessary to hold back on the handles to further reduce forward movement. After the soil is broken apart, slight upward pressure on the handles produces faster forward movement of the tiller. During the actual tilling operation you may try to maneuver a turn. The compact tiller is versatile and will react to turning maneuvers without any damage to the tiller. However, experience and soil conditions will dictate degree of turn. The tiller can be pulled backward and turned easily, since the drag stake pivots out of the ground.

To condition the soil effectively, a definite tilling pattern must be used. Till a single row; then skip a space equal to the width of the tines, and make the return pass. Continue this pattern until the entire area is broken apart. Next, condition the entire area again by tilling at right angles to the previously tilled swaths. When the entire area is broken up, till deeper by raising wheels and adjusting handle force for a slow propelling rate. A four-inch depth of conditioned soil is deep enough for most row crops and turf, seed-bed areas. Vine crops, however, usually require six or more inches of conditioned soil.

Another tiller application is conditioning soil that has been tilled previously. Even though the soil has been conditioned before, the ground must be dry for the effective reconditioning that may be required. Do not till when the soil is wet. Engine speed should be regulated to produce good pulverization of the soil, and this is affected by the type of soil being conditioned. Never condition the soil until it becomes granular or powdery, because the surface soil will have a tendency to pack and resist plant growth. If the general texture of the soil is somewhat sandy, use only enough engine speed to loosen the soil for planting. Other than engine speed, the use of the tiller and tilling pattern is the same as when untilled is first conditioned. Keep the wheels adjusted so that an erect, non-straining operating position can be maintained.

When cultivating - uprooting weeds - the tiller must be controlled carefully to avoid plant damage. To maintain control of the tiller, adjust wheels, engage drag stake, and reduce engine speed. Wheels should be adjusted to allow the operator to maintain an erect position.

In summary, till or cultivate the soil when it is dry, because better "conditioning" will result. Maximum engine speed is required to break up soil that has never been tilled. By comparison, regulate engine speed as required when conditioning soil that has already been tilled. Cultivating, by contrast, requires reduced engine speed so that precise control of the tiller can be maintained. And, after the tiller has been used, hose off any dirt and vegetation from the tines, pulleys, belts and shroud. Wipe engine with a damp cloth, in preference to spraying it with water. Store the tiller in a clean, dry garage or storage shed.

IMPORTANT: 1) Always make sure that air cleaner is cleaned and serviced before operating tiller. 2) Make sure blower and air cleaner are free of debris. Clean every 4 hours when tilling dry vegetation or dry, dusty soil. If this is not done, chaff will build up in blower housing, causing engine to overheat.

MAINTENANCE

CAUTION

Shut engine off before performing any maintenance service. To prevent possibility of accidental starting, pull high tension wire off spark plug. Make sure that wire does not contact plug accidentally (Fig. 19).

Figure 19
High Tension Wire in V Notch

SERVICING AIR CLEANER

Tools Required: Screwdriver

NOTE: The air cleaner element must be cleaned after every 25 hours of engine operation. However, element must be cleaned every few hours when operating conditions are extremely dusty or sandy.

1. Pull high tension wire off spark plug.
2. Remove screw and cover to expose air cleaner element (Fig. 20).
3. Inspect air cleaner element at the inlet holes on the bottom of air cleaner, and at the top of the air cleaner element. If element is dirty or discolored, it must be removed from the air cleaner body, then cleaned.

A. WASH element in a solution of liquid detergent and water. Squeeze element to remove dirt, but do not twist the element, because it may tear.

Figure 20
Air Cleaner Element

B. DRY element by wrapping it in a clean rag. Squeeze rag and element until element is dry.
C. SATURATE element with 5 teaspoons (25 ml) of engine oil, and squeeze element to distribute and remove excess oil. A damp element is desirable. Next, put element into body. Also install screen and spacer on top of element.

1. Install cover on air cleaner body, and make sure cover and element form a seal. Mount air cleaner assembly on top of carburetor with long screw. Make sure that all parts are seated in place and form a seal.

IMPORTANT: Do not operate engine without air cleaner element and screw mounted in place, because engine damage will likely result.

REPLACING SPARK PLUG

Tools Required: Spark Plug Socket Wrench, Spark Plug Gapping Tool and Clean Rag

Since air gap between center and side electrodes of the spark plug increases gradually during normal operation of the engine, check condition of electrodes after every 25 operating hours. Recommended air gap is 0.030 of an inch (0.76 mm). Correct spark plugs to use are Champion RCJ-8 or Autolite AR7N.

1. Clean area around spark plug so foreign matter cannot fall into cylinder when spark plug is removed.
2. Pull high tension wire off spark plug and remove plug from cylinder head.

MAINTENANCE

1. Check condition of side electrode, center electrode and center electrode insulator to make sure there is no damage.

IMPORTANT: A cracked, fouled, dirty or defective spark plug must be replaced. Do not sand blast, scrape or clean electrodes because grit may eventually release from the plug and fall into the cylinder. The result is usually a damaged engine.

1. Set air gap between center and side electrodes at 0.030 of an inch (0.76 mm) (Fig. 21). Install correctly gapped spark plug with gasket seal, and tighten plug to 15 ft-lb (20.4 N'm). If torque wrench is not used, tighten plug firmly.

Figure 21 Air Gap Between Electrodes

1. Do not install high tension wire onto spark plug unless tiller is to be used immediately. This prevents possibility of accidental starting.

CHANGING CRANKCASE OIL

Tools Required: 3/8 Inch Open End Wrench, Shallow Oil Drain Pan, and Clean Rag

Check oil level after every 5 hours of operation or each time tiller is used. Change oil after the first 2 hours of operation; thereafter, under normal conditions, change oil after every 25 hours of engine operation. However, change oil more frequently when engine is operated in dusty or sandy conditions. If possible, run engine just before changing oil; warm oil flows better and carries out more contaminants than does cool oil.

1. Position tiller on level surface so oil drains completely and a true reading results when crankcase is refilled.

2. Shut engine off, and pull high tension wire off spark plug.

3. Clean area around drain plug (Fig. 22). Next, place shallow drain pan below drain plug so oil can run into pan.

4. Remove drain plug from crankcase, and let oil drain into pan. To make sure that oil drains completely, tip tiller slightly to the rear.

CARBURETOR ADJUSTMENT

Carburetors are adjusted at the factory, and normally do not need adjustment unless they have been disassembled.

INITIAL ADJUSTMENT

Close needle valve (turn clockwise — (Fig. 32), then open 1 12 turns (turn counterclockwise). This initial adjustment will permit the engine to be started and warmed up before making final adjustment.

FINAL ADJUSTMENT

With drive clutch control released (tines stopped) and engine running at normal operating speed (approximately 3000 rpm without load) close the needle valve slowly (turn clockwise) until engine starts to lose speed (lean mixture). Then slowly open needle valve (turn counterclockwise), past the point of smoothest operation, until engine just

MAINTENANCE

begins to run unevenly. This mixture should be rich enough for best performance under load (Fig. 32).

Hold throttle in idling position. Turn idle adjusting screw until fast idle is obtained (1750 rpm).

Test the engine under full load. If engine tends to stall or die out, it usually indicates that the mixture is slightly lean, and it may be necessary to open the needle valve slightly (1/8 to 1/4 turn counterclockwise) to provide a richer mixture. This richer mixture may cause a slight unevenness in idling.

Figure 32 Carburetor With Air Cleaner Removed

WARNING

Engine must be running so final adjustment of carburetor can be performed. To guard against possible personal injury, disengage drive clutch control. Keep hands, feet, face, and other parts of the body away from the tines, belts and pulleys.

IMPORTANT: Air cleaner must be installed on the engine whenever carburetor is being adjusted. The air cleaner mounting screws must also be tight when engine is run. Fuel tank must be half full of gasoline to get best carburetor adjustment.

PREPARING TILLER FOR STORAGE

1. Drain gasoline from fuel tank: Refer to Draining Gasoline From Fuel Tank, page 16. Next, start engine and let it run at idle speed until it stops because all gasoline is used.
2. Pull high tension wire off spark plug, and clean area around the plug so foreign matter cannot fall into cylinder when plug is removed. Next, remove plug from cylinder head and pour two tablespoons (25 ml) of engine oil into spark plug hole. Pull recoil starter handle slowly to distribute oil on inside of cylinder. Then reinstall spark plug, and tighten it to 15 ft-lb (20.4 N·m). If torque wrench is not used, tighten plug firmly. DO NOT INSTALL HIGH TENSION WIRE ON SPARK PLUG.
3. Drain oil from crankcase: Refer to Changing Crankcase Oil, page 14. However, do not fill crankcase with oil at this time.
4. Clean dirt and chaff from outside of cylinder, cylinder head fins and blower housing. Also, remove vegetation, dirt and grime from external parts of tiller chassis, engine, shrouding and tines. Make sure idler pulley pivots freely.
5. Check and tighten all cap screws, bolts, screws, nuts and mating parts. If any part is damaged, repair or replace it.
6. Lubricate wheels and pivot points: Refer to Lubricating Wheels and Idler Pulley, page 15.
7. "Touch up" all rusted or chipped paint surfaces. Make sure to sand affected area before painting.
8. Fill crankcase with oil: Refer to Fill Crankcase With Oil, page 7. Clean air cleaner element: Refer to Servicing Air Cleaner, page 13.
