I have a heavy duty Bush Hog brand 6 foot brush hog. This Spring I mowed down quite a few saplings and thorn trees etc. Most under an 1 inch in diameter, some up to 3 inches or so. It worked well. Today when I took it out it would barely cut 6 or 8 inch high grass. When it got into the thicker grass the PTO shaft was rotating slowly. I think the slip clutch is slipping, either that or could the main nut holding the blades on underneath be loose? I have had it to the dealer twice in the last 2 years because the nut came off and the blades came off. I told them to torque it high enough or use loctite or spot weld it. Hopefully it is not loose a third time.
If that is not it and the slip clutch is slipping. Can I just tighten the nuts slowly, say a half turn each and see if the puts more tension on the unit so that it cuts the thicker grass? Keep doing so slowly until the unit functions and does not slip excessively. Thoughts or ideas. Thanks
