Hi, I am a new member but not new to the site. I have searched your discussions many times in search of advice and I often find that someone else has experienced the same problems. I recently had my 4WD stop working on my 2005 TC40DA (1000hrs) but couldn't find the answer, perhapse I didn't look hard enough. I did discover the source of the problem so I decided to return the favor and post my findings. So I finally took the time to register. Anyway my problem turned out to be where the drive shaft connects to the spline on the front of the tractor. The shaft is connected by a female coupling. The splines on the front part of the coupling were rounded off. This prevented the drive shaft from turning the front tires. 36$ dollar part from New Holland and I was back on the road. Anyway hope this helps someone else and thanks for all the good advice I have gotten from you guys over the years.

Thanks Mizell and :welcome: to TBN. That splined collar has been a source of frustration for lots of users. Sometimes the rollpin that holds it in place will shear and the spine moves out of position. I'm sure glad your fix was simple and the cost low. Anytime you can fix a tractor these days for $36, that's reason to celebrate.:drink:
