I cut the fingers from my 2.25 powerclaw...works much better. I had a problem before with the nose coming up too much during slow, full throttle moves in sidehills or climbing. Gets up on top much better now and the slow, full throttle situations the nose stays down better.
To cut mine off, was pretty easy. I used a sawzall and pair of large vice grips. I would rotate the track so that the finger was horizontal off the back idler wheel, clamp the vice grip on the end of the paddle (which would bend it down a bit) and then would cut from the top of finger downwards...as the cut progressed, the weight of the vice grip kept the cut well open and avoided any smoking or friction and didn't need oil or anything. Cuts were clean and it was simple. I didn't cut too close to the bottom...left about 1/4 to 1/2 inch on each finger. Worked great and was fast.
