Using tractor driven tillers (wasRe:[AT]AllisChalmersB-1lawn tractor

[Gilbert Schwartz]

Charlie; Now that you mention it I don't remember a shear pin doing what
it's supposed to do, when it's supposed to do it. I did twist off the
gearbox input shaft when I hit a broken off fence post and the clutch didn't
do it's slipping business. Happened to have another gearbox but couldn't get
the clutch to slip so went to a shear pin probably mostly for peace of
mind.Started with soft bolts and after getting tired of crawling off and on
the tractor went to harder bolts. Haven't had any trouble since but then
haven't hit anything really unmovable either. I don't generally run very
hard with a brush cutter and definitely not fast. It seems like it's too
easy to run over the ground without cutting off what you're there for. I
kind of like to give the thing a chance to do it's thing. That heavy,
spinning inertia seems hard to start and really hard to stop Gil
