Turn the ignition key counterclockwise to the ROS "activated" position
The accessory clutch lever must be forward (deck engaged)
Slowly press the reverse pedal to initiate movement

Accepted Answer

To change the belt on the Husqvarna CTH126 garden tractor, follow these detailed steps:

1. Preparation

Ensure that the engine is off and the ignition key is removed to prevent any accidental starting.
If possible, lift the front of the tractor using a jack for easier access to the belt area.

2. Accessing the belt

Remove the access panel located under the tractor or around the belt housing, depending on your model's configuration.
Unscrew the fasteners that hold the belt in place if necessary.

3. Removing the old belt

Detach the worn belt from the pulleys by gently freeing it.
Note the routing of the belt around the different pulleys to facilitate the installation of the new one.

4. Installing the new belt

Place the new belt following the same path as the old one, ensuring it is properly positioned on each pulley.
Make sure the belt is properly tensioned and aligned.

5. Reassembly and checking

Replace the access panel and screw it back securely.

Question 5

How to diagnose and resolve a problem with the hydrostatic transmission of the HUSQVARNA TS 138 tractor?

Accepted Answer

The hydrostatic transmission is an essential component of the HUSQVARNA TS 138 tractor that allows for power transmission and speed control. If you encounter a problem with this transmission, here are the steps to follow to diagnose and attempt to resolve the issue:

1. Check the oil level

An insufficient oil level can lead to poor performance or damage. Check the oil level of the hydrostatic transmission using the gauge provided for this purpose and top up if necessary with the oil recommended by the manufacturer.

2. Inspect for leaks

Carefully examine the hydrostatic transmission and its surroundings for any oil leaks. Leaks may come from worn or damaged seals that will need to be replaced to prevent more serious failure.

3. Listen for abnormal noises

When operating the tractor, pay attention to unusual noises coming from the hydrostatic transmission, such as squeaking, clunking, or excessive vibrations, which may indicate an internal problem requiring professional intervention.

4. Check responsiveness

If the tractor responds slowly or erratically to movement controls, this may be related to a malfunction of the hydrostatic transmission. Check the mechanical connections and associated cables to ensure they are not damaged or loose.

5. Clean the filters

Some models are equipped with filters in the hydrostatic circuit. Ensure they are not clogged, as this could limit oil flow and affect performance.

If after these checks the problem persists, it is advisable to consult a specialized technician for a thorough diagnosis and appropriate repair.
