I purchased an NT204 in March of 2005. The machine is used for mowing and plowing snow, and I have recently begun to do some grading around my property as well. I've got 41 hours so far and have done nothing but fill the fuel tank and change the oil. No problems or warranty issues to report. I'm pleased with the purchase. The tractor is everything Northern advertised--and then some. (I think if Northern put some more information in their ad copy they probably would attract more customers. It's a bit of a stretch to lay out $5k based on a 3x3 inch ad with a few highlighted features, and the "informational video" than Northern offers doesn't help much either. I had already decided that I wanted a Jinma and was somewhat familiar with the machines before I bought so I didn't rely on Northern's catalog to make the sale). Crate machines have some appeal, but with shipping factored in the price wasn't that much lower than Northern's sale price and I appreciated the fact that Northern flushes and runs in each machine prior to shipment. I understand some folks have received the run-around from Northern when problems arose, but overall most seem to report a positive experience. Again, I have had no contact with Northern since I placed my order a year ago and therefore can't comment firsthand regarding warranty service, but I wouldn't hesitate to buy from them again.
