Like I said, I see no reasoon a small backhoe could not be used with the 4100. There are several differences between the rear end of my 2410 and the 4100 but I cannot see that one is better than the other, just different. I added the backhoe kit to my 2410, it consists of a heavier duty top link bracket, longer bolts and a few other bits. I wish I had a backhoe but I just spent 25,000 dollars on a new engine for my airplane project so once again I am rather poor. The only real reason I need a tractor is to build me a runway and then keep it mowed and the Kubota is much better for that--why you ask--I can see my bright orange Kubota from the air much better than some silly green thing so that while my wife is mowing the runway while I flit about I will not land on her by accident. Why would anyone paint a tractor green anyway?
The pictured tractor with the backhoe is a 4110 I think, certainly not the 2210, how do I know, the 2210 has the black plastic floorboards like the 4010, the 4110, does not. I would expect for JD to have or develop a backhoe version sooner or latter of the 2210--why not? J
