I use my tractors hard.
My TN75 has been darn near unstoppable. (TN75DA (cab), 2007 16x16 power shuttle)
I did have to replace the battery in it this last week, I don't think that's a big deal.
I had two hydraulic hoses get cut (they were routed wrong at the factory), and that was the total warranty work I've had in 2 years.
I put it on a PTO dyno, it made 69hp. It's only rated at 67 and I'm at 5000 feet. It's a great motor.
Well designed cab, very ergonomic and easy to get around in, easy to maintain. (unlike the TC cabs which are LTO)
The quick lift feature is awesome, it's my favorite thing on the whole tractor. The 3 point hitch is well designed, incredibly strong and easy to hook up.
It's made in Italy and by far it's been my most reliable piece of equipment, how ironic is that?
The loader is pretty slow. It lifts what it should, but it's slow. But I don't think ag tractor loaders are all that fast so I don't think that's a deal killer.
