I have the KAMA 254 C, and from when it was new the power steering is strange. you have to keep turning the steering wheel to the left all the time to keep going in a straight line. going about 1/4 mile down the road the steering wheel will have to be turned to the left about 4 complete circles. the tires are not towed in or out too much. any ideas would sure help. has 300 hours on it..
Sounds like the steering cylinder is bypassing internally, you need to take the cylinder apart and check the seals, I have seen this happen on new tractors where the seals were damaged during assembly. We prob. have a rebuild kit,need to know the rod size in mm.
