This problem started last May pulling 4 row striptill rig. Hydraulic oil overheat alarm went off. We changed filters with no change. Changed sensors and no change. Carried it to Dealer shop and they rebuilt SCV couplers with no change. Back to dealer and they rebuild SCV control valves with no change. Mechanic came to field and said fan clutch was weak. Changed it and engine ran cooler but hydo oil still hot. We finished planting without finding the problem. This summer all the tractor did was run rotary mower with no problem. Put harrow on yesterday and in two hours alarm went off. The transmission is quad range and I was working in B 4. I let it cool till the alarm went off and changed to C 3 and ran same speed at 1600 RPMs with no problem. Changed to C 2 and ran 1950 RPMs with no problem. Changed back to B 4 and in 20 minutes alarm went off. Immediately changed to C 2 with alarm still flashing and in two minutes alarm quit and never heated up again. We pull the planter in B 3. The next thing the dealer wants to do is rebuild the transmission to the tune of $8000.00. Any opinions out there of what the problem might be. The dealer seems to be fixing possible causes with out really knowing what the problem is.
