...they are very light and do not generate the power of some of the other brands- new holland, massey, deere etc. they are great on fuel. the rule of thumb on kubotas (from farmers) is buy a kubota a size or two bigger than you might need to compensate....
What?! ^That's a first for me^.
I won't get into the tractor branding war because I don't want to turn your question into a Ford vs Chevy thread. However, I have a Kubota 5640 4x4 w/front end loader, a Massey 240, a Massey 245, and I used to have a Massey 135. I'm in love with my Kubota. A 30HP+ tractor would pull about anything 5 or 6ft long (bush hog, tiller, disc, etc) without any problems. For a 56 acre farm, assuming your whole farm is not one big grass field that will be a good sized tractor for you and do you well. Like any tractor, or any piece of equipment it has it's limitations and here and there you'll find jobs that are too big for it I'm sure. I have a 56HP Kubota and I find jobs around the farm that are too much for it, but that's just occassional.
The only thing I personally do not like about the L3600 is the hydrostatic transmission. Would it keep me from buying one? No, not if the price is RIGHT
. However, you do sacrifice some power with any hydrostatic transmission, and to me, it's just one more thing to tear up. 800 hours is nothing by the way. I don't know what the price is but you make it sound like a steal. I don't think you will be disappointed.
