You could split the difference with a L3560. A little more weight and lift capacity than the L4802, not as big as an MX or larger framed Grand L. The L3560 costs less than a L4802 too.
Consider if you’ll want/need rear remotes for top and tilt or an offset flail mower to mow your pond banks. The Grand L’s have better ergonomics for placement of the rear remote levers as well as more weight.
Wade, consider getting the tractor with two rear remotes so you can get top and tilt for that box blade. You’ll be glad you did so you don’t have to hop on and off the tractor twenty times every time you want to adjust your box blade.
That’s a good metric, thanks for posting. It’s confusing the way Yanmar lists the weight of the YT’s in the brochure. Up close they’re every bit as big as a Kubota Grand L.
