I have friends with Kubota
M7040 and M9540. Both have good things to say about their tractors. Another friend has a JD 5525 w/FEL and 6420. Nothing negative about these, except once when the narrow 5525 and FEL made for an unsteady situation.
Kubota has a large amount of experience in compact tractors. I am not sure how long they have been making larger tractors, but the Mxx40 series are only about 2 yrs. old.
Farmers, auctions, farm equipment sales magz. all have JD green from front to back with the occassional orange scatterred in. But JD has made the larger tractors for alot longer, and they have a entire range of tractors not even offerred by Kubota.
I THINK if I were buying, I would look at how much I would be demanding from my tractor. If I were using it on a regular basis and under heavy applications, I would PROBABLY go green.
I have never buckled down and got ready to purchase, but I considered talking to a local contractor before buying. I have noticed a fleet of Kubota tractors bush hogging the interstate ROW's, and I have also notice a fleet of JD's doing the same. Maybe it's a different contractor, but if the same guy just changed fleet, then he would have many hrs. on both orange and green.
I would put some value in his opinion since I would mostly be bushhogging.
Everyone has their favorite features, and one of my most favorite features that I like to look for is $$$$$$. So operate both, find your likes/dislikes, then weigh them out vs. the $$$$$.
My friends 5525 has the 24 spd with is an expensive option and the dealer said it was not worth the $$$. He may be right, but since I did not have to pay for it I really enjoy the extra gear options.
Maybe next week I can spend some time on the 9540 and see how I like it. Best I remember, it was vinyl/plastic interior and the JD was cloth, comfy. More like a car, pretty quiet too.
If I remember correctly JD's 4720 cab is sealed. The 5525 may be as well. Kubota also maybe, but it may be worth considering if you are in dusty conditions. I had ran a unsealed enclosed cab skid steer, then I stepped up to a JD 9520 and they could not pry my hands off it's steering wheel. I was not giving it up for somebody else to operate! It's mine! The dust would be boiling up outside, yet clean and dust free inside.
I probably caused more confusion than help, sorry.
