I have fairly steep areas and like to cut some of it across the slopes. i also like pulling a trailer, so a lawn tractor works best for me. I've had the best success with a JD X series. Before that I used a Cub Cadet 54" with power steering, but it was not on the same level as the JD. To get the trans filter and diff lock you have to get a X570 or bigger I think. Years ago you could get a X300 series with a HD K78 with the removable filter, but no diff lock. I've gone through too many cheap mowers, they aren't worth fixing after three years here. My JD lawn tractors runs and runs, the larger HD trans has held up fine because the fluid gets changed, much higher toque capacity, the removable cartridge filter makes a big difference in longevity too. I have a L4330 Kubota for the 6' bush hog 286, thats been a great machine combo. My Kubota is a 2003 with the OEM loader, still runs like new. I would have a dedicated diesel Kubota lawn mower if I had the money to spend. Maybe a B series with a belly mower, but the JD gas mower does good.
