Everything was working great... was backing up after dumping the front loader bucket, and the tractor stopped as if I pushed in the clutch. All the hydraulics stopped working, no deterioration of any kind just.....nuthin...hmmmm

Its either that or problems with the charge pump inside the front transmission case since it works the forward neutral and reverse system plus supplys oil to the main front pump. Im thinking the tractor should drive itself without the front pump since the fnr system works from the low pressure charge pump. Please let us know what you find out. I have a 310a that i use everyday loading gravel and would like to know the reason if mine ever does this.

I agree on checking frt hyd pump coupler. Also could have stripped the hub out of the engine disconnect clutch.
So, if it might be the low pressure charge pump, what would it have done to suddenly stop working? The tractor does not move. How could I check the charge pump, and is it the block mounted bottom right side of tranny where the forward/reverse linkage comes in?

If I am thinking straight....it is in the pump. There should be a single electric connector on the top of the pump.

I think tx jim may be on the momey. The hub on the engine clutch may have sheared off the rivets causing the transmission input shaft to quit turning. Thus stopping the charge pump. I had a IH 986 do this once.
