The TYM T603 tractor's 4-wheel drive may not engage due to several possible reasons:

1. Transmission Issue – The front wheel drive power is taken from the rear transmission. If there is a problem with the transmission, it may not transfer power to the front differential.
2. Differential or Final Case Problem – The power is transmitted to the front differential and then divided into left and right wheels. If there is damage or wear in the differential or final cases, the 4WD may not function.
3. Gear Engagement Failure – The 4WD mechanism uses level gears for power transmission. If these gears are worn, broken, or not properly engaged, the system will not work.
4. Hydraulic Clutch Issue (if equipped with IPTO) – If the tractor has an Independent Power Take Off (IPTO) with a hydraulic clutch assembly, a hydraulic failure or air in the system could affect engagement.
5. Mechanical Disconnection – A broken or disconnected drive shaft between the transmission and front axle could prevent power from reaching the front wheels.

Checking these components and ensuring proper engagement should help diagnose why the 4WD is not working.
