The MMM works great, but the 1526 wants to be on full throttle in tall grass with open chute. IT doesn't seem to bog down much. Medium range full throttle, full speed. The high range I find a bit too tall, but the tractor goes faster than one with a 2 range HST. The HST has 3 ranges and it has an oil cooler, so you can abuse it as much as you want. Sure a few HP more would have been nice, like the older model... But in real live you aren't going to notice that in that application. I suppose you can turn up the fuel some. I looked at Max26 (too small), the 1526 (perfect size for what I wanted it for, while it being just little more $$$ than the Max26 and a third HST range) and the 1538 (too big and too much money). I wanted 4wd, a big MMM and be able to pull a 72" boxblade and handle the hinged offset flail mower. I added a second hydraulic remote to the rear.
