Hi I just bought a fiat alice hd11 ep. the left hand steering clutch doesn’t work to well you have to stand on the left brake in order for it to turn. Also when pushing a heavy load of dirt with it I. First gear it will slow down to nearly nothing and the driveshaft barely spins. Will changing the hydraulic filters and or transmission filter solve my problem? If so where are they located?

I was also wondering since there are two separate fill holes for the hyrdaulics and the transmission?

Transmission drain plug is accessible through a square plate on bottom of belly pan, pretty well straight down from the seat. Bevel gear compartment (separate oil) has three drain plugs, one in the rear center, and then one on each side for steering clutch compartments. Hydraulic drain plug on HD11Ep is at the front of the tractor... The screen in the transmission is quite large and there would have to be major problems for it to be clogged.

Transmission pressure filter is in front of dash on LH side.

Ok thanks!
do you think changing the fluids will fix my problem with it slowing down to almost a snails pace when pushing a heavy load of dirt without spinning a track? It will spin a track when not warmed up all the way. Is there a torque converter filter?

If the driveshaft stops turning, the problem would be in the torque converter..

You will need to change the transmission oil if it is milky and clean the trans screen which is easy to get at , use ATF trans oil
