If error code 35 and new clutch sensor didn't fix the problem. This could be fault with the ECU. Too high or low voltage, bad battery etc. can cause ECU failure. Clutch pos. sensor has 5V supply and voltage converting components might be failed. This is maybe the case with PASAME's tractor. Testing with fully functional ECU might shed some light.
zgemboo: Checking hydrive unit hydraulic pressures could help figuring out if it is electronic or mechanical/hydraulic problem. There is testing points on each banjo bolts on left hand side of the clutch housing. M12 threaded tapping i think. Forward and reverse clutch pressure should be within range of 0-18bar and of course high when engaged. Third connector is lubrification pressure.
