I have had repeated trouble with failed shear bolts on a brush hog. Pretty sure the problem is/was with me. I'm new to two-stage clutches and have moved from a 23hp gas to 47hp diesel tractor. I figured once I got the hang of the two-stage and used the correct diameter shear bolt, I would spend more time mowing, less replacing sheared bolts. Bought four shear bolts and ended using all of them yesterday. Just letting the clutch out too quickly will fail a shear bolt, mowing along and hitting a fire-ant mound will fail one, mowing into heavy grass or a one inch sapling - snap! Having the blades go to ground shears them as well. Over six years, the gas tractor rarely snapped a bolt no matter the sapling size or ant mound size, so it must be me and this tractor.
My question is this; while it is common for a piece of equipment to require a certain level of horsepower tractor, is it conversely true that you can over power a piece of equipment... like a simple brush hog?
It's an older, unknown mfg. brush hog, spent it's life behind a couple of Ford N's and a 1900 before being gifted to me. I am considering going up to grade 5 bolt.
