Thanks mcmxi. I also contemplated (and tried out an M6060) the dealer had, but it was open station. The M6060 is a more significant tractor in terms of weight, the larger 3.3L engine, better loader, a little more PTO horsepower, etc. The cab version was only a few thousand more than the MX at least the way I've configured mine. In the end, I decided I still wanted an HST tractor because I mow steep slopes (dams, reservoirs, capped landfills, etc) and wanted the very precise control near the water's edge, top of a dam, etc. I ran a Glideshift Kubota years ago and it required careful attention in these areas. I took the R4 tires mostly because I really like the wide steam-roller appearance of the MX R4's. I previously had an MX4800 open station with the R1 tires. They grip awesome but are a lot narrower. I always run spacers on the rear, so I've already got 2" Bro-Tek spacers on order. The dealer will set the tires to their widest rim position and load them with BallastStar. My dealer required the optional CCV heater. I've added a couple of rear remotes, the trailer plug, the outside mirrors, the seat arm rests, the rear work lights, rear wiper / washer, and re-added the right side cab door latch and lock. Of course a stereo system; I like the Jensen marine radio the dealer installs with the NOAA weatherband that will actually break in over the radio, bluetooth, CD, etc to warn you of a storm.
Some of the grass I mow will be very dense and tall, the L4060 would struggle through these sections and you'd have to go very slow. The Stall Guard feature would constantly be kicking in. If this machine can power through smoothly, that will be awesome.
