I have a 2002 JD 4200 hydrostatic , rear wheel drive and it has three speed ranges, A, B and C. Yesterday I was driving down the road in the High
range (C) and the tractor came to an immediate stop just like when you suddenly take your foot completely off the forward pedal. When I pushed the
pedal back down, it would stall and I would restart the tractor. I was able to restart the tractor and drove it home in low gear (A), but when it was
in B or C range, it would stall but it was very difficult to shift between the ranges. When I got it home, I shut the tractor off and then could
shift it between A, B and C, but it was difficult to find neutral. I was able to drive the tractor again around the yard, but it would only operate
at very low speed without stalling in B or C range. In low range (A), it is fine. Now I have it back in the garage and have it is in low range (A)
but it will not shift to B or C, the gear selector is locked up in the low range. A few months ago, I put brand new fluid in the tractor.... J20D low
viscosity, a new hydraulic filter, and I removed and cleaned the suction screen. The fluid at that time looked like it was old but there was only
very minimal material/filings in the suction screen. The loader and the three point on back are working fine. Any ideas of what is going on here????
Thanks for any help.
