I cleared snow with the new RTV-X1100C "for real" (outside of practicing operating the unit) for the first time this morning. Super impressed with the power of the blower, overall RTV power, stability, & traction. I have the HD worksite tires, and didn't carry any extra weight in the bed. The cab is great: I had to lower the heat because I was getting too warm. I turned on the AC because the windshield was fogging up and it worked like a charm. The windshield wiper came in handy.
I was getting frustrated with shifting for the first 30 minutes because some areas that I clear require a lot of backing up / go forward maneuvers, and it felt like the transmission more often than not would not smoothly shift into reverse then back into "L". I tried two mitigation techniques: (1) with my foot on the brake, "blip" the throttle pedal briefly, then attempt to shift. This helped somewhat but annoyed me every time I had to do it. (2) swampy6 mentioned that changing the height of the front implement (in his case the Boss V-Plow) helped. I tried this with my blower, and I was surprised that it did sometimes help.
Then for some reason things started getting better: I think the main change was me having a lighter touch with the shift lever. If I encountered any resistance, I jiggled the shift lever slightly, then tried again, lightly. Things just seemed to work better. I only had to use the floor throttle "blip" a couple of times in the second half of my snow clearing. My frustration level dropped, and I began to enjoy the job.
It is odd to me that shifting difficulty seems to be a widespread issue for people, and Kubota hasn't done anything to address the issue. But I am heartened by the fact that maybe me adapting to the quirks may be enough to let me enjoy this otherwise GREAT machine.
