Rotary Cutter Bush Hog Rotary Cutter Blade Problem....Help??

[BB_TX]

When you hit the log, it probably almost sheared the bolt. Or possibly did shear it but the PTO collar was tight enough on the cutter shaft that it was still spinning the blades. After more cutting, it finally gave up.

I do the same thing on ground hog hole mounds. Always sneak up on me too. I don't have a shear pin though, just a slip clutch. Should it still stall with the slip clutch, or should I check the clutch plate torque?

Gerald, I think suddenly hitting something solid would shear the bolt or slip the clutch, but I guess going into something like dirt that's not a sudden or sharp impact, but very quickly applies a great amount of load can bog the engine down instead. However, since I lived in an area with almost no rocks, I've never personally owned an implement with a slip clutch. I do know that they require a bit of maintenance, so I don't know whether yours is in need of adjustment or not.

John Miller III obviously is quite familiar with the maintenance and adjustments so maybe he can advise you.

Not familiar with slip clutches on farm equipment, but familiar with them in other applications. Their principal is essentially the same as a shear pin.

During normal use, there is a certian amount of force placed on the pin / clutch. When a specific "breakaway" force is reatched, the pin breaks or the clutch slips. When a pin breaks, it needs replacing before proceeding. However, with a clutch one has to be more careful.

After the slip clutch slips, one must remove close to all of the force placed on it for it to re-engage. I guess what i'm trying to say (and poorly I might add) is that one can go back to the original force and the clutch will still slip since the breakaway force is what is keeping it from slipping in the first place.

I have seen where the person just continues to use the equipment and burns out the clutch since it is continuing to slip. It is always safe after hitting an object to stop the implement and check for any damage. This also allows the clutch to stop spinning and "reset".

Sorry this is such a poorly worded post. Maybe someone more mechanically inclined than I can do a better job! /forums/images/graemlins/smile.gif

I was rereading my Woods manual this past weekend and it states "remove all rocks, logs etc. form the cutting area before using". I guess I just never thought to do that /forums/images/graemlins/smirk.gif. With information like that how do you know what really important!
