Thanks for the input. I took the Deere xl178 in, it will be about $150 to fix a pulley and it will get running again. I run it pretty hard, with chains, and pull a 10 cu. ft. wagon full of limbs, vines, rocks, etc all over the small property. We are currently remodeling the house and deck, so there is construction material all over the place right now. I have lots landscaping to do in the next year at this new property and don't know if the Deere will last long. Whether its me or the tractor that gets broke on the slope is another question.
Also, I went and looked at several 4wd tractors in the past few days.
Simplicity Prestige and Legacy XL. I think the legacy xl is in the price range of the deere x748 and kubota bx1860.
Ventrac 4000. The dealer was informative about the 3000 series though and recommended it for my type of application. It has a lot of attachments and is probably a bit more than I'd like to spend at around $12,000
Test drove Kubota GR2120 and BX2360. The GR2120 has a lot better turning capability than the BX platform. But you get a tractor with the bx which I don't think I'll need after next year. I'm lucky that my dad offered to let me borrow his Deere with a FEL if I have a weekend project.
The Prestige and GR2120 are probably front contenders for my needs. I used a phone app to see the slope angle that I had been cutting and hanging off the side of that Deere. A lot of 20 degree slopes and several 25 and 30 degree sections. The GR2120 diesel with ag tires looks like a winner but the cost is a lot for a mower. $8600 with 54" deck. The prestige was a little lower, but that kubota glide steer was slick and the turn radius was great, even comparing to the small deere.
Hooking up a Johnny Bucket Jr. to the Kubota or Simplicity would probably take care of 98% of what I'd like to do with the tractor.
