Yes, I have only used my new RZT S42 for 2.2 hrs but so far I am totally, did I say totally impressed. My property is mostly hills with some at 30 deg. Incline and some soft and wet spots near the river.
With my previous cub cadet lawn tractor it used to be a scary balancing act to mow those hills and I used to tear the lawn so bad near the river, I sometime had to pull me out of the mud with the quad.
With my new toy I was able to tread lightly in the worst wet spots (with all the rain we had lately) it has to do with the control you get applying power without having one wheel spinning madly.
My other 'like' on this machine is the steering, precise and very direct, with its capability to do a 360 on itself---WOW! Very useful to get out of tight places.
As any good reviewer you have to find something to improve upon, mine would to add a guard to the throttle lever as I was making good use of my new found zero-turn capability, hugging a tree, twice a branch hit my throttle lever pushing it back to idle. The first time I thought HOHO did I break my new toy, the second time I said to myself I got to make a guard for it
but I am not eager to drill holes in my new machine.
Ho, did I tell you I was impressed with my new RZT S 42.
