Stump grinder build Idea.

[massey driver]

It wasn't to cold of a day so moved some stuff out of the way and took a couple pictures.This gear case as you can see I have a spare piece for it.Whats unique about this is that it has a over run clutch built right into it.If you look close near the guard you can see a rod sticking out that at one time must have had some kinda of linkage to shift it into netural of drive.I have the guard holding the shifter in gear all the time.But that doesn't affect the over run clutch so in away it's pretty good to have.I can idle the tractor right down and the over clutch takes over and lets the cutting wheel slow down on it's own,not affecting the tractor at all.No idea what this gear box was off[maybe some sort of old hay binder] all I know is that it works excelent.The person who had it before me had tried making a 3pth post hole auger.He had welded two different size fligthing onto each of the long pieces,I've cut them off and used one for the stump grinder.I do know when I put it onto the tractor[when it was still a auger] that thing turned like crazy.Bet thats why it was never used for post hole digging.It's something like 1 1/2 times faster on the output then the input shaft.So for a stump grinder it works just fine.Anyone have any idea as to what this gear box is off of??? It's got MH cast right into the cast housing.So its pretty heavy even with it grinding it doesn't bounce hardly at all.It's not something you want to try and lift and put into the truck to often. Sorry about not showing the wheel and teeth but you can't really see them with the guard in place I used a old air plane tire for the side guard its sandwiched between 2 plates of 1/8" steel.Don't want anything flying out and hitting me the operator while it's being used.Using the tire allows the wheel to be completely covered in from the side yet still flexable to give and be out of the way while grinding.Haven't had any problems.Had to change the teeth only once since making it.I have lots of stones etc: and sometimes the stump is grown into a stone so all in all I'd say its stood up pretty good.By the way its ground out 200 plus stumps over the last few years,now its getting used less as I only need to grind out stumps when we lose tree's.

Massey Driver,

Thank you for taking the extra effort to post pictures of your machine.
It is not quite what I expected, but it sounds like quite a unit. Especially after chewing up over 200 tree stumps.

David,

Thanks! That's about what I had envisioned turning my shredder into, but your simpler design has given me ideas and hope!

Thanks for all the feed back guys. When I get a chance and a little better weather I will post some pics of the dump trailer I made. Shortly after I completed the trailer it was rearend by an 18 wheeler. Done I pretty good number on the trailer. I will post some pics of the damage and pics after I fix it. I am waiting to get it on the frame machine at votech to straighten it out. The trailer was pulled home. The 18 wheeler was towed off with a lot of damage. It was undrivable. The driver wasn't paying attention and smacked the trailer doing about 45mph. Spun the trailer and truck around 360 degrees. My nephew had borrowed it. Lucky he wasn't hurt.
