tl100a 4x4 stays on

[lars]

I've got an 06 tl100a that only has 300 hours on it and just recently the 4x4 stays on. The tractor is 100 miles away at the inlaws farm and I'm going up this weekend to check it out so haven't been around it myself. I called the dealer I bought it from and was told that when you put the unit into 4x4 the solenoid/hydraulics are required to disengage the clutch pack, which actually powers it into 2 wheel drive. Also when you are in 2 wheel drive and hit the brakes it puts it back into 4x4 for extra braking by cutting hydraulics and re-engaging the clutch packs. I think the idea is that it will fail safe (into 4x4) if something does go wrong with the solenoid.

I plan to check the solenoid and switches to see if resistance is ok and power is getting to the valve. I may find it's something simple and the service guy said as little as the tractor is used, being in 4x4 is ok.

Just curious if anyone else has had a similar thing happen. I'm new to tractors so I don't know how common this 4x4 system is.

Thanks - Dan

I apologize for the duplicate post. When I visit this site I quite honestly have not been to the parts and repairs section as I usually go to the NH threads or sometimes the attachment threads, and have really never been on threads for other makes of tractors. I wasn't sure if some other brands of tractors had the same 4x4 system and someone like me might not visit the NH site but would go to repairs site.

I appreciate your input on how the 4x4 indicator lamp is acutated on my tractor.
