and watch it! Unless you are clearing rough, rocky or steep ground, after some adjustment to the track tension, you should be able to finish your work about the time the undercarriage is finished.
If you are on rough, rocky or steep ground you can likely still get it done, just change to more of a "watch it and run it" mode.
I like the ol' D6B and would probably still have mine it it had a p/s tranny.
Which of course would have made it a D5
You only need two tools in life - WD-40 and Duct tape. If it doesn't move and should, use the WD-40 If it shouldn't move and does, use the duct tape.
