Here's a few of my recently (yesterday) completed home-built root rake/grapple ... I'm sure lovin' it so far:

Interesting and quite novel clamshell design. I like the fact that the upper arm pivot point is moved forward a foot or so. That will prevent the dreaded "pinch point" problem inherent to clamshells where the first log is clamped but prevents the grapple from closing further so the rest of the load falls out.

Show us more of what it can do. Nice work!!

That was the idea ... ;)

My pleasure.

Thanks ... :eek:

Thank you very much.

I spent most of today moving debris - mostly old logs and stumps - to the rear (south) property line. There used to be a large pile of them in the photo below:

There's a shared trail between my neighbor (east) and I, which connects to a gas line right of way on the south end of properties. It's where I took these two photos from.

We've both had some problems with trespassers, so I blocked off access to our properties (via that trail) from the gas line right of way:

Still have many, many loads to go.

Yesterday (and this evening) I worked on clearing out the area below ... we used to have a garden (mid-ground, on the far side of the wood pile) ... in the background the trees have encroached from my neighbor's property, which is what I was clearing:

rswyan, can you show us some photos of your grapple without a load to demonstrate the geometry wide open and fully closed? Side view would be best. The pivot point arrangement is unique. I thought initially that the pivot point was forward of the frame but another TBNer pointed out that actually there is a pivot point at the frame it's just higher than on a typical clamshell. It looks to me now like you avoided the pinching problem of a scissor type joint by designing in a void with "C" type upper jaw so there is never contact between the upper jaw and back of the grapple as happens with a typical clamshell. What do you call your design? A cantilevered clamshell????

Hopefully that solves the problem.

We used to have "public" trails through our place and the neighbor's properties, but one by one we (land owners) took it upon ourselves to blockade the access(s), and I was the last parcel to end the era. Potlatch owned my property before me, and the folks who held the hunting lease didn't care what anyone did back there as long as they weren't messing up rifle deer season. I had a lot of hate mail when I took over and ended the free-for-all, but it only took a couple trespassing citations to get the message out I was serious.

Sure, wide open:

Works pretty good for raking too:

IMG_0118.jpg

Jaw opening, tip to tip = 55 1/4"

Jaw height from ground when open, with lower jaw/frame oriented vertical = 54"

The one below is of it closed ... BEFORE I cut off some metal on the upper jaw arms (where it was contacting the bottom of the hydraulic cylinders and preventing it from closing further) and lengthened the hydraulic cylinders by 1/2".

It closes a little further now - the tips of the upper jaw are probably within an inch or so of the slots in the root rake:

Sorry ... don't have any current side view pics of closed in it's current config. If I can remember I'll snap some later today ... :D

Sounds good to me ... :thumbsup:

Yeah, I hope so too.

Had three middle school kids come strolling through the other day ... had to read them the riot act (Ahhh ... just exactly how stoopid are you guys anyways ?) ... particularly given that they crossed two other properties before they hit mine, both of which were clearly posted.

Told 'em no second chances ... next time they will be detained until the police arrive.

They aren't the ones I'm really concerned about though.

Unfortunately, I (and my neighbors) can't blockade all of the access - due to gas line right-of-ways - they have to be left open ... something the new guy a couple of places over is going to find out when the gas company maintenance crew comes thru with their big New Holland tractor and finds he's chained their right-of-way ... :laughing:
