That's a good question. I was shopping that size range and compared the Bota and Deere, Kioti as well. I found them comparable - now you've got me scratching my head. I don't recall there being a huge difference in the specs. With that said, the Deere Dealer I ended up buying from pointed out that some published specs are hard to compare because they don't use a standard measurement methodology. He of course said the Deere 430 was every bit as good as the Bota I was comparing it to, and offered to let me try it out and see.
I ended up buying the Deere simply because I believed it would do everything I needed it to do. The dealer is top notch and has taken great care of me and the tractor well after the sale. After 70+ hours of hard use I can say with experience that the Deere 4310 and 430 loader combo is no weakling. I pop small trees, I've moved everything imaginable in this old mother earth. In the past 3 weeks I've loaded and moved about 100 tons of fill, rip-rap, and 3/4" gravel as I've been reshaping my yard and driveway. It will do everything they say it will... So will the Bota! Don't get too loaded up on specs - I did and it got confusing after a while. Comparing is important, but keep in mind nobody in the reputable brands is making bad tractors.
Find a good dealer and you'll be really happy with the purchase - whatever the brand.
Good Luck! /forums/images/graemlins/cool.gif
