Rotary Cutter bush hog not cutting

[newbury]

Thanks everyone for the advice, it's working!

everything was turning, and I thought the slip clutch was tight, but once I held onto the drive shaft and pulled on a blade, it slipped. So I re-tightened the slip clutch bolts and it's cutting.

I did touch up the blades with an angle grinder, not sharp to the touch, but about a 1/16"-1/8" rounded edge and no burrs.

Thanks for posting the results.

i thought it was recommended to loose and spin the clutch and the readjust yearly to make sure it wasn't stuck, and not let go when you really need it. if there is anything on the surface of the clutch plate wouldn't scotch brite take it off.

I ran it for about an hour cutting and it did great, no slippage as it cut cleanly.

Things look fairly even between the two sides of the clutch for contact (no worn spots I can see). I'm not sure if I tightened it enough, but I was worried about going too tight.

I'll keep an eye on it and repost. Hopefully someone else will learn from my dunce moment!

Yep, you are supposed to slip the clutch. They are made to be slipped when they encounter an obstacle and then rengage on their own. I intentionally slip mine every spring to unseize them and the clutch will get warm. Don't take it apart to clean it, just properly adjust it and forget about it.

You'll know if it is too loose because it will stop cutting grass or it will get hot to the touch. Check it for heat periodically until you are confident it is not too loose. You want it to slip when you hit something pretty hard.

If this is your worst "dunce moment" you have done very good. Really don't care to think of my list of those. At least nothing or no one hurt and no big price tag. Just tell your family and friends.

Never seen one yet that was in need of "resurfacing" after it slipped.

Nor I.

way0ut, once u think u got it adjusted correctly, mark it with a paint stick or something so u could tell whether it was slipping. U don't want 'any' slip unless you contact immovable objects.

Like a 'shear bolt', they're designed to 'give' unto 'major' obstructions.

Thanks for the advice. I'll mark it and check it today while clearing out pasture.

ok guys...my bush hog was cutting then for no reason it stop cutting the grass...mmmmmmmmmm now the blades do spin..lHOWEVER, how do you get them up high enough to look under? I am going to look for the sher pin thingy tomorrow. It started making a noise that was scaring me and I mean to tell you I don't scare easy. So how can blades move and not cut? Give it your best shot before I have to get out there with my scissor and cut 6 acres. thanks guys...woman in need of help.
