When the machine is cold it works great. After using it for about 1 hour I start having trouble with the right steering but only in the forward direction. When first using it its very smooth but after 1 hour there is a lot of vibration when steering right-like the clutch is not fully releasing. If it is steered in reverse there is not a problem. Any idea what could cause this problem?
Those clutches are oil applied, the brakes are oil released. Works good untill warmed up is translated into a leak some place. Need to get some gauges and check clutch and brake pressures when warm as you operate. Then we can help you. Later Bob
