Jinma Tractor

Operations amendment advice

Our JINMA tractors are not recommended for constant 4WD mode unless traction is lost and tyres are actually slipping.

Never operate in 4WD on a paved surface, roads or any non slippery surface. Bind up damage will occur (no differential between front and rear axles) if the tyres cannot slip, 4WD mode must be disengaged immediately when tyres stop slipping.

It is normal for the little front wheels in 4WD mode to out run the big rear wheels...... which means they have to slip, otherwise torque damage may occur.

The following procedures for 4WD operations must be followed:

4WD Operations

  • 4WD mode must only be engaged when rear wheel traction is lost.
  • Immediately Disengage 4WD mode once rear wheel traction is resumed.
  • If the front wheels are turned sharply try not to release the clutch too quickly
  • Ensure all movement is ceased before engaging or disengaging 4WD mode
  • Ensure engine rpm is idle before engaging or disengaging 4WD mode
  • Fully depress clutch before engaging or disengaging 4WD mode


REMEMBER: 4WD mode must be disengaged immediately when tyres stop slipping, otherwise bind up damage may occur.
