Tractor stops pulling in forward or reverse

[David Hayes]

I have a new holland TC55DA, EHSS. Purchased this machine new. When I first start the tractor it will move OK. Then it quits pulling, doesn't matter if in forward or reverse. I can cut it off and restart it, pulls fine for a few feet, then quits pulling. After this happens several times it starts pulling again for a short time and does same thing, quits pulling. I have changed filters and hydraulic oil. No help there. This is first problem that I have had with this machine. Engine runs great. Can someone give me an idea what the problem is? I have checked the dump valve, it is working OK.

Thanks for any help.

How is your rear tire pressure.? Several people have noted the rims turning but not the tires under load. Low pressure and cold weather. Just an idea.. You would never know, as you are sitting on the tractor, have someone stand on the ground, and observe the wheel/tires.

OK.. let us know what it was when you get it figured out, I was hoping it would be something simple.

I will surely post here when I find out the problem. I think it is the EHSS controller Module. When the problem happens, I can turn switch off and restart the machine, the machine will move fine for a few minutes then stop pulling again. I think when I shut off the switch that resets the controller module. I have checked all wiring, nothing is loose.

This is one of those times when you are going to have to bite the bullet and call a service tech. With the electronics it can be something really simple like a sensor or it could be the module. With out the right diagnostic equipment you wont figure it out without spending a lot of $$$ on parts you don't need.

After many hours and a lot of money spent. Found the problem. It was the HSS Controller Module. The tractor mechanic spent several hours and could not diagnose the problem. Thanks for your suggestions.
