The local tractor dealer in town quit selling Woods because they were having a lot of problems with gear boxes and they couldn’t make any money because Woods is way overpriced. Their words, not mine.
  What did you expect them to say, when/after they stopped selling Woods rotary cutters?  lol
  This is what Woods calls their medium duty cutter, (their words not mine) it has a 115hp gearbox, and yes, they do make a heavier duty cutter too,
  Here it is, just about to take out a 3+ inch tree,
  That is how I got all the extra trees out of this field,
  I have three Woods cutters, I do this for a living, do you really think I'd keep a rotary cutter around that was always having gearbox problems??
  The OP isn't looking for a "medium duty" cutter, he's looking for a higher quality lighter duty cutter...
