building a tree grubber

[kossetx]

I'm building a tree grubber. I would liked to build one for the fel with multiple teeth like some others have shown here, but I decided against it until I get a qa fel bucket though.

What I am going to do is make a 3pt grubber using a middle buster frame to make the grubber. My Howse MB uses a 3/4"x 6"X 28" "shaft" for the middle buster bolted to a frame. I got a hold of some 3/4X8X36" plate which I'm going to change out with the shaft for the MB. It simply bolts to the frame with 2, 7/8" bolts so I can change them out fairly easy. I'm trying to determine how long to make the shaft out of this 36" piece. I'm thinking 18" should be more than enough for the shaft of the grubber. If I cut the 36" onto 2 18" pieces, I could use the other 18" piece to make the tooth/teeth out of. I'm thinking the lower to the ground I make the grubber the better it will pull. A longer shaft would help keep the tree from falling on me, but I'm only going to try pulling 1-3" trees so I don't really see that as a problem. I'm still up in the air on whether to make 1 V shaped tooth or multiple teeth for the grubber part. It will mostly depend on how long I make the shaft.

Anyone have any thoughs on this?

sounds like a good idea.I wish I would have thought of that. I built one today using 3"x 1/4 wall square square tubing and 3/8" plate.havent cut the teeth yet, still up in the air about how many teeth and how far apart.never used one so i do not know what would work the best.yours sounds much simpler and lighter than mine,let us know how well it works
