I bought a used 2002 kubota L3010 HST with 200 hours. The only problem is the loader valve lever has to be in the exact spot while pushing down or the bucket will not lift. All other functions on the valve work perfect and there is no play in the valve or lever. You have to push the lever down to the perfect spot and the bucket will go up ,if you push down farther the bucket stops and holds the height it's at and you can still push the valve down more till the lever stops. the bucket still stays in that position. This problem is the same loaded or empty. I had an old kubota and you could slam the valve in any position and it worked fine. This problem makes loading a truck a pain. Any help would be greatly appreciated.
