Hi I'm New, Please Help ! ! I have B2710 325hr. 4 Years old use mostly for cuting grass at home about 80 hr a year. After 20 minutes of running at high PTO speed the steering becomes stiff and hard to turn. It does this no matter what RPM's I'm running at. When turning to the extreme left or right I can hear a whinning noise. The only other time I notice it is when I first start the engine, for the first minute the steering is a little tight, but not as bad. I think this stiffness is normal while the hydraulic fluid is warming up. I also notice that the past year the Hydraostaic pedal in low, medium or high range, is a little jerky at times when you go forward or backwards. However, the problem with the steering once the engine is hot is realitivly new. Is there any flow adjustment or bleeding the lines other than turning the wheel to the right and left? All the fluids are at the right level and I have really kept this machine up with all of the service and fluid changes. Change Hydraulic oil at 50, 100 and 2 mo. ago @ 300 hr. Used Kubota Super UDT and Kubota filters. Also clean screen that was not dirty. Please let me know if you can help me out with this problem. Thanks, Staci /forums/images/graemlins/confused.gif
