I have an 806 that looses steering when it gets warmed up and will also stop like you had pushed in the clutch when you turn the steering wheel. You can turn the wheel back a little bit and then continue to drive. Can anyone tell me what in the world is going on?
Thanks, Elvin

Chadd's got it right. Most likely a problem in your MCV (Multiple Control Valve) or MCV pump. The MCV controls steering, brakes, the TA, and transmission lubrication. Since the direct drive clutch pack in the TA uses hydraulic pressure to lock up, it will unlock and cause your tractor to stop moving when the pressure drops. I can tell from this that the low side of your TA is out, since the mechanical sprauge clutch for the low side requires no hydraulic pressure. If you've got a couple thousand bucks to throw at this tractor, I'd recommend installing a new TA, a new MCV pump, and rebuilding the MCV valve.

More than likely the same thing that is wrong with ours. The MCV pump is probably starting to get bad and so when several things are trying to be used at once, it runs out of pressure and something gives. It will usually happen when the steering is turned to its lock and also when you press one brake all the way down. We don't have the time or the finances right now to fix it, so we just make sure not to turn super short. Otherwise it involves pulling the entire MCV (the plate right in front of the stair to get on the tractor) out and replacing the pump mounted on the back. It might also be a valve though too. The only way to know for sure is to flow test it, which most people (me included) don't have the tool to perform.
