Bob, They really don't say. They only state heavy gage steel. It does weigh 41 lbs. I am guessing 1/4 in. but 3/8 in would be stronger. They have about 5 different versions.
J_J, thanks for the link. It looks like for many things (like trenching) this is similar to a back hoe or minihoe, but it would not have the leverage of the curling backhoe. For taking out a stump it would be able to work around the tree and cut the roots. As an add on to a bucket I would see some advantages. Do you have any thoughts on this.
Bob, It would be good for those operators that do not have a mini-hoe. It is light weight, easy to install, and can dig faster and deeper than a human.
Hi, Im trying to design a tree transplanter for my school project. But I am not sure how to calculate the force required to push the blades into the ground. Does anyone has any idea how to determine that?
You would have to put a force scale on the blade and measure how much weight it takes to break the soil. Also, a lot of it depends on blade shape, size, weight, soil type, moisture content, etc... lots of variables.
There are plenty of trans-planters around. Are you wanting to build something special that has not been used before, or you looking for something easy to use to transplant. Is it something a person could use, or is it for a machine? These units below are for tracrtors and SS.
Moss, if you want to try the tree spade I made for my 425/refine ideas, contact me. I built mine from the frame rail of a semi tractor ( high carbon heat treated steel ?} similar to the picture JJ posted. Works fine up to 4'' hardwoods, after that the tap root is to much for lift capacity of tractor
