Luke: A good tree puller should pull 1/4" through 10-12" trees (assuming the tractor has the ba!!s) without loosing grip or shearing the stem. IMO. Can you please post a link to this tree puller. I just would like to see an implement that will pull up a 10" to 12" tree, see what it takes to power it and of course see the price.
I bend the 4" trees on purpose to break them to get the upper part out of the way, don't know why I just do and then attack the standing 4" trunk which I get out with the JDUNN Grapple by going back and forth and curling the bucket back and forth. It grips, I'm not slipping off of the trees just breaking on purpose.
I'm sure you know an L3901 does not have the balls/traction/weight to pull out of the ground anything much over a 4" rooted tree, if you've ever done any tree "pulling" instead of using your backhoe to dig them out. I see you have some bigger, heavier tractors with BH at your disposal. I wouldn't use a BH, even if I still had one of them, for the 2" to 3" sapling since this JDUNN Grapple just grabs them and pulls them out of the ground quicker than I could set up the feet and get the seat turned for BH use.
Sorry you think I'm getting defensive about an implement that I just paid near $2000 for that works better than I expected and fits my needs perfect and have actually used for a few hours (Like actual hands on experience) instead of judging it's strength, use, limitations and abilities by watching one youtube short video. My invitation is still open for you to come try it yourself and then give your opinions of what it is or isn't.:thumbsup:
