I am a dealer, for FarmPro, also a Jinma based tractor. I do have an AgraCat in my shop now that is two years old and I can see no difference to Jinma except some nice emblems. I think they probably pay a bit more attention to cosmetics on the new ones to help justify thier higher price,but I have not seen a new one They did offer a two year warranty, but I don't know if that is still the case.
I am planning to drive up to Farmington soon to take a look, especially their new LG based tractor and ATV, Skid Steer, and excavator lines too!
I was told that the new JINMA LE version was supposed to be a proprietary design for Agracat to help differentiate it in the market, but it seems Yancheng Tractor Company has sold it to several other importers too! (Chinese have a unique business ethic).
I suppose the proper answer is that SOME Agracats are Jinma but not all, Some are now LG and there is a huge difference in both quality and price between the JInma models and the LG models.
