Jeff, I sold the tu1700 to an 82yr old man that loves it. I think the Iseki tractors are a very good tractor. I currently have a TS1610 Iseki, E14 Hinomoto, S630 Satoh and I would say the Iseki one of the best. The 3cyl in the Tu1700 is a plus as for as the smoothness. I am interested in the TL Iseki [ TL2100 or TL2300. If the price is right ? You want go wrong on the tu1700.
