Project All-Klaw (root grapple)

keep us posted!

I am building a root grapple from two halves of an old Prentice log loader "pulp bucket" that was owned by my Grandfather Allen--(the "All" in my project name).

Each one measures 20" wide.

That's cool, I grew up in the town that makes Prentice Loaders, "Prentice, WI", I have several friends and relatives that work there. Good Luck with your Project!

Thanks all for the interest.

Rob-- I'm guessing I'm somewhere in the 500-600lb range

In these pics I have cut out the plate from between the tines and welded on my QA brackets.

This is what the "thumb" of the grapple looks like.

I squared it all up, welded in 1.5" box tube across, then used 3/8" steel for gussets and reinforcement.

I used another piece of 4" C channel to protect my hydraulic cylinder.

Out at the tips, I used 3/8" x 1" steel for reinforcement. I would weld 1.5" then bend down with a crescent wrench, continue my bead, bend again, until I had worked my way out to the point. It gave me a nice curve.

I used 1" dom tubing for my pivots and 63/64" rod.

I recycled the 1/2" plate cut out from between the tines to make my mounts for the hydraulic cylinder.

man, that turned out great!

i like how you saw something out of nothing......and then built it...

That is a great job, probably better then factory

To finish up, I welded angle iron across the back of the center spacer to give me a flat area to weld in the 1.5" rod recycled from the beginning of the thread. I also welded in the center tine.

I also welded dom tubing on the outside of the four pivot mounts for the clamshell. Before welding, I drilled a vertical hole, perpendicular to the tubing/pin to accept a lynch pin, one for each pivot. I also drilled and tapped both pivots for a zerk fitting.


Sanded, wire brushed, primed and painted!!!

Testing 1-2-3

Everything seems to be working good. I think that the clamshell does not open far enough, and gets in the way when nosing into brush.

I lowered the base hole for the hydraulic cylinder. This maximized the stroke of the cyl., allowing the clamshell to open further and allowing the gussets to rest on the tines in the closed position.
Previously there was about an inch gap in the closed position, now it will have a stop.

I also made my decals and put them on.

Very Impressive.

How many hours did it take you? What are you using to cut your steel?
