I have a Kubota
B2710 which I bought used about 13 or 14 years ago with about 200 hours on it. It does not have loader and wish it did but never thought of loader on it when shopping. Like it a good bit and have used in in some ways that some would be surprised at. Have pulled 500 gallon sprayer with it, dirt was firm or it would not have done that as the loaded sprayer out weights it. Great with rough cut mower in the woods as it is easy to back into tight spots. I have brother in law with a 4 series JD he bought last year I have operated maybe 2 hours. Big difference in the size of the two tractors and I really prefer the JD 4 in size over my
B2710. This is not an apple to apple and I realize that but for what is worth:
Kubota (I have two one bought new in 1999 a
M6800) and they rust. Sorry. Metal hoods and fenders get scratched and they rust. Weld seams on roll bars rust. It not just mine I have noticed that on either. Reminds me of the Japanese cars from maybe the 70's.
My
B2710 does have 3 speed HST and my brother in laws JD 4 series has 2 speed HST and noticed that right off. His JD has fel and used it a good bit and never had issue with it needing another speed. In reality the lowest range on my Kubota is only used for improper reason, using to move tractor while standing on the ground to hook implement. On the JD to me the fel control was in bad location as I would hit it when turning to right to watch backing up. Took me a little while to realize why the loader was changing when backing.
Again my
B2710 and the JD series 4 are not same size but think the lift arms are heavier on the JD but those on my Kubota have done well even though both of the sliding stabilizers have slight bows in them.
For my nickle the Kubota makes very good engine but think their transmission is light weight compared to JD. This has shown up with my
M6800 twice requiring transmission repairs under 1,000 hours.
Have used the rocker pedal on the Kubota HST for years but think the side by side of the JD is easier as it does not require the lifting of the foot to change the direction.
I have enjoyed my two Kubotas and may buy another but three years ago bought a used JD larger tractor and prefer the JD. Might sound odd but it just feels great. Have others who has used it and they say the same about how good that tractor is to use with comfort being some of it.
