Frequently Asked Questions - GAR 840 T Hydrostat GUDE
How to start the GAR 840 T Hydrostat lawn mower?
Make sure the tank contains petrol and the ignition key is inserted. Press the parking brake, set the transmission to neutral, then turn the key to start the engine. Wait a few seconds before engaging the blade.
How to adjust the cutting height?
Use the central adjustment lever located to the right of the seat. Turn it to select one of the 7 positions, ranging from 25 mm (low cut) to 80 mm (high cut). The mower must be stopped to make this adjustment.
The hydrostatic transmission is not working properly, what to do?
First check the hydraulic oil level (see manual). Make sure the transmission pedal is not obstructed and the cable is properly tensioned. If the problem persists, contact an authorized Güde service for a hydraulic pump overhaul.
What engine oil to use?
Use SAE 10W-30 oil for 4-stroke engines (API SJ or higher). Oil capacity is approximately 1.8 liters with filter. Check the level with the dipstick regularly.
How to clean the mower after use?
After each mowing, clean the cutting deck with a water jet, avoiding spraying the engine and electrical components. Remove grass residue under the hood. Dry the machine before storage.
My grass catcher does not fill completely, why?
Check that the ejection flaps are open and the catcher is properly clipped. Ensure the blade rotation is sufficient (max engine speed). In wet weather, grass sticks and blocks the flow; mow in dry weather.
Where to find spare parts for the GAR 840 T Hydrostat?
Spare parts are available at your authorized Güde dealer or online on the Güde website. Use the model number (GAR 840 T Hydrostat) to identify references.
What to do if the blade does not cut well?
Inspect the blade: if it is dull or damaged, sharpen or replace it. Also check the tension of the drive belt and that the engine speed is sufficient (full throttle).
How to store the mower in winter?
Drain the fuel tank or add a stabilizer. Clean the machine, grease pivot points, remove the battery and store it in a dry, frost-free place. Cover the mower with a tarp.
The safety cuts the engine when I get up from the seat, is this normal?
Yes, it is a normal safety feature. The engine stops immediately if you leave the seat with the blade engaged or the transmission in gear. To restart, sit down, disengage the blade, shift to neutral and turn the key.
