has anyone ever replaced the pressure or friction disc/discs on a Bush Hog brand rotary cutter? Mine sort of disintegrated today. They had been taking to overheating ang smoking and stinking several times lately. I guess this was really the last straw.

I don"t know what model of Bush Hog that you have, but I will give you the starting point for the models 285, 286, and 287. There should be eight bolts with springs on them on the slip clutch pack. Back off each nut a little at a time until all spring tension is removed. Remove all nuts and springs. The clutch pack should now be able to be pulled apart at this point. If you are lucky, the metal bearing surface of the clutches is not in too bad a shape. Install new clutch disks in the clutch pack and put the unit back together. Reinstall the springs and nuts. Tighten all of the nuts equally till the distance between the bottom of the nut and the base of the spring is 1 1/32" for the Model 285 and 286 and 1 1/8" for the model 287. This is a good starting point for the slip clutch adjustment. Start the tractor and engage the PTO and see of the clutch slips. If it does tighten each nut by two flats and check again. Slip do clutches require some tweeking over time due to wear of the mateing surfaces. Hope this helps.

Learning2Pull got it exactly right. Didn't we have sorta this conversation last week about how some of us cherish the opportunity to learn here even though some seem to only come here to be rude?

Anyway, the original poster didn't need the BS - anyone who reads the first post will see he knows he needs to replace the thing - he was just asking for some advice on how to do it. Wish I could help him but I don't know either - although i look forward to someone posting something helpful then at least two of us will learn something worthwhile.

I'm sure he appreciates the rude explanation there JMS/.MN . Consider the possibility that maybe not everyone in life has experience with slip clutches instead of being condescending to someone asking for honest help. This forum could stand more folks like the ones on here offering support and info and less of people with a PHD in BS.

Thanks for your comments. It made me realize that I didn't need to feel stupid or bad even though i may have been abusing the equipment. I have learned from my experience.I never could , except by experience, determine how much to expect from this cutter. It was so tempting to make short work of that rubble. It was just too much.When rotted pieces of just about any size or 18-24" pine were encountered the cutter seemed to handle them as long as a longer piece didn't jam up the swing of the blades.

You burned it up because you overloaded it. Everything has its limits. Drive slower. When you smell asbestos burning- you are overloading the slip clutch. When you see smoke, you are overloading the slip clutch. When pieces of the slip clutch fly out, you have ruined the slip clutch. This is a duh ... question.

That's why I hate slip clutches. They have to be adjusted frequently. They burn up pretty quick if they start slipping and you don't see it for awhile, and they're a pain in the neck to change. Give me a shear pin any day.

You talking about the slip clutch? If it is smoking.. it is slipping...

yes, it would the slip clutch Im talking about. It seems that several pieces came flying out of the doorpoening in the plastic shroud. I was chopping too heavy of material at the time.
