I purchased a new TN65 in 2002 and shortly thereafter the tractor started leaking oil or diesel out the exhaust manofold. Hauled it 50 miles to the dealer, they ran it on the dyno and I picked it up. About 150 hrs later the same thing. Back to the dealer, back on the dyno, and then back to pick it up. About a month ago it does it again. This time the New Holland rep gets involved and they found a leaking valve cover gasket and decided to send the injection pump in for excessive smoke and low power. I waited three weeks with no word so I went to the dealership and learned that the mechanic had dropped the key out of the injection pump into the tractor and from what I could see of my tractor most of the motor had been removed. The service manager said they were waiting for a gasket to come in and would have the tractor back together in a matter of hours once it arrived. That was five days ago and in two days my tractor will have been in the shop for one month. My question is; at what point should I be able to expect New Holland to buy back this tractor or give special consideration on a replacement tractor? Even if they do get mine "fixed" it may be some time before I know for sure since the problem is intermittent. Plus, if I ever decide to sell most people will back away when I tell the tractor's history.
