cbturf-
The machine is a Tiger cat M760 with a 10 foot mulcher head. Most guys in our area are using 720s for tree shears. My machine is 400+ hp . Working in the mountains of VA and other areas in VA as well. The machine has differential locks for steep grades. When working on steep grades, I usually back up the grades rather than go down them.
I have another question- I go in the ground at least 3 inches, does anybody else out there go in the ground? Looking at hours per teeth, how much are you guys averaging for a set of teeth?
