After reading about your land and intended uses, I think you do need a larger, heavier tractor.
Our Kubota
L3400 is heavier than the Deere you mentioned, and if you will be doing snow removal, "feet at a time", you should consider size as important. I need rear spacers and chains to deal with deep snow (rare, thankfully) or the tractor gets pushed around by its 78" front plow. Our old
L3130, which weighed maybe 2000 lbs more with its heavy loader assembly and filled rears, was much better for plowing, with the same 78" plow, with better "blade" control.
For us, with about 1000' of lane to clear, a snow blower is too slow, and having used a loader bucket and rear scraper blade, I don't want anything other than the front plow. Okay, a cab would be nice, too, but it ain't gonna happen.
A SSQA loader and 3 range HST, as mentioned, would be very good. Consider filled R-4 tires, as well?
