Here is the stupid question of the day.
Are those R&K *cart* wheels stock?
I have a full set on my 1542. I was told they are not.
Anyhow in the speculating dept.... Hour meters are art, not science.
My tucker has 19,000+ miles and according to the hour meter it averaged 19MPH grooming snow in the UP of Michigan....
With idle-ing time and grooming, 1.5MPH isn't out of line, I might be able to sustain 4.5-6 MPH Grooming, If I go into beast mode and flat foot it 9 MPH is achieved, with glowing exhaust.
Just $.02 worth of banter
