A friend of mine has a Gehl CTL60 (Takeuchi TL130) with 1200 hours, that is experiencing loss of boom and bucket power. The track drives seem to be fine, but the aux, lift and bucket controls are very slow or do not work.
The problem started today after snow blowing for 4 hours. Towards the end of the day the blower did not seem to throw the snow that great. The machine then started to shake and make a constant noise similar to when you run your aux with nothing connected but worse. The noise would go away when the lift arm float valve was opened. The owner parked it and a few hours later I was able to come by and look at it.
When I got there and started it up, the lift arms wanted to go up all by themselves, but only a few inches. They would not go down until the float was activated which allowed the arms to drop and made the noise go away. Once we moved the machine to make sure the track drives were still working, the arms stopped lifting themselves, but the noise and shuddering was still happening.
We disconnected the snow blower to see if that was the problem, but it did not help. The only function that barely works is when you curl the bucket to dump, BUT rather than lifting the machine it raises the boom like the float is enabled. This did not make sense to me, as it should lift the machine up. I also had disconnected the float solenoid to see if that would help and it did not.
We plan on checking the pump pressure at the aux connection once we get the right fittings for the pressure gauge. I did check for leaks, and anything that may be out of order. The hydraulic fluid level was fine. The filter was changed in the fall and he has put very little hours on it since. The machine was run for many hours during a recent snow storm with no signs of problems. We are looking for suggestions on where to start looking. I unfortunately do not have a service manual for this machine.
