I own a Grand L series L3130 with a Kubota LA723 loader with quick attach, heavy duty 72" bucket, Woods tooth bar and a 72" Woods GB72 box scrape. I also have a friend with a Kubota M5400 with a Woods 1027 loader which I operate some. My Father bought a Kubota M6800 about two years ago.
So maybe I can help you a little...probably not as much as most of the people on here...but i can try. One thing I did that helped me decide was reading the posts on here about certain projects that people did with their tractors. The other thing I did was go to my dealers and get as many different brochures as I could on tractors and attachments...in the size ranges I thought I wanted and of course, afford. I then studied the brochures for a few weeks...comparing everything as much as I could with reading material.
A Kubota M-series runs from about $18,950(M4900SD 4WD, 50hp., R1 Ag. tires, ROPS) to $38,300(M9000HDC, 4WD, Cab, 90hp., hydr. shuttle trans. with LA1251 loader, R1 tires) at Rhinehart Equipment Co. in Rome, GA.. The Grand L series runs from about $12,350(L3130DT, 31hp., R1 Ag. tires, 8X8 shuttle shift, ROPS) to around $20,000 for a L5030. I was given a quote in November 2004 for a L5030, hydro, ROPS, R1 Ag. tires at my dealer...not Rhinehart...$19,600.
For comparisons on other models I will list a couple other tractors listed in Rhinehart ads.
L2800DT, 8X2 trans., 4WD, R1(R4's add $450) $10,450
BX23TLB $14,785
M6800HD, 68hp., R4 ind. tires, 8X8 Hydr. shuttle. $22,770
These prices could be higher or lower than where you live, but it should be a rough ballpark figure.
I hate to make a post so long, so could you give more specific's on what weight, size, horsepower tractor you might be wanting to look for?
My L3130 has plenty of power for what I need it for. It is a heavy machine for its size. I like the Hydro transmission verses gear. Gear has its specific uses though, plus it costs a little less. The Grand L (31 to 50 hp) series tractors are the largest size I am aware of in the Kubota line where you can get a Hydro transmisson. In my opinion, a loader is a must. Good for all kinds of chores from hauling things around the property to digging up shrubbery and jacking up the front tires, plus digging dirt. A toothbar is also a nice feature to have on your loader.
As far as brand I think all of them are probably fine machines, so I can't say one is better than another. Kubota just had the specs. and options I was looking for. Plus I owned a grey market Kubota L1501DT hydro years ago which was a fine machine for its size and I have a Kubota ZD21 mower which I really like...no problems at all in roughly 177 hours. I did look at John Deere, New Holland, Kioti, Branson and Mahindra.
I think from what you have described so far, something between 30 to 50 hp. in a compact series with a loader, backhoe, box scrape and bush hog would suit your needs.
If you are going to be doing lots of hay work, you might look at something like the Kubota M-series tractors. Maybe this will help you a little.
