What are you planning on doing with the machine mostly?
What machines are you looking at?
Primary tasks are loading manure in spreader and spreading on field, moving and grading limestone and gravel for paddocks and buildings, and I'm building another barn next year, need something bigger to handle that much excavating. We're also going to start buying hay in either large squares or round bales, so I need something that can move bales up to 1500# since that's what's available around here for good prices. I also pull a bush hog but would be completely happy with what I have for that. When I bought my B2710 I really underestimated how often I'd need to use FEL. Our problem is we're land locked for access by semis except when there's no crops in the adjacent field, so when I have something delivered I have to dump it on one side of the property, then load it in my dump trailer and move to the other, then spread it. My tractor just takes forever.
I've borrowed my neighbors JD which is 30HP, can't remember model number, that's still clearly too small. My last neighbor had a JD that I used, that was about 40 HP and in retrospect that was about right, but I was too worried about tearing up grass and leaving ruts. Now that I've graded things and put down gravel where I need it, that's not an issue. I also realize I can just wait for the ground to dry out and it won't leave ruts (duh). So I'm looking at L series and M series that are about 40-45 HP. I have to cruise over to the dealer where I bought mine, I don't understand difference between L and M with comparable engine size. Kubota web site sure isn't very good comparing tractors from different families. It seems like M series are cheaper than L series for comparable sized engine, but it's hard to compare used equipment. I also want a cab, tired of freezing my tail feathers in winter.
