If you're buying a 'logging' chain its should have a grab hook on one end and a slip hook on the other.
With the slip hook end you should be able to rig up a choker that holds well enough that you're not needing to drill the trunk.
Cut the trunk 3 or 4 feet high, but hook to it lower so that if rigging does start to slip, it's not popping of the top.
You want the tractor end of the rigging to below the centreline of the rear axle -- so the pull cannot flip the tractor over backwards. Perhaps not with GT's, but many have been killed by ignoring this with (small) tractors.
Hook point on the tree/shrub is a trade-off.
The higher on the trunk you can rig, the more mechanical advantage the pull has to break roots/pull the plant out. However, if it's too high, the chain tension can reduce the weight on the rear axle of tractor reducing traction.
Short chain hookup length and chain hooked at the ground will add downforce on tractor, increasing traction and increasing lift on plant -- but loosing the leverage advantage from hooking higher on the plant and loosing the safety factor from being further away from the plant.
In the early '70's dad and I pulled out a huge number of small trees and bushes with a small (30 or 40hp?) 1950's farm tractor. If you have a bunch to do, you'll soon figure out how to get a chain choker to work and the best height/hook-up length combo for the ground conditions, the size of your GT and the size/type of plants being pulled.
Hydraulics are your friend. I've done some cleanup in the yard and in fence rows over the years with a Case TLB, and have done areas measured in acres with a JD 25 ton excavator.
If I had many to do I'd be renting/borrowing a backhoe or mini-excavator. Faster and safer.
If only a few to pull and if in tight quarters a come-along is maybe another suggestion along with the jack-all-jack one.
Obviously, it makes a difference if you clearing overgrown stuff out from beside the house to prepare for new landscaping vs clearing a spot at the edge of a wooded area to build a shop or make a garden.
This all great stuff thank you.
So as funds are tight I want to buy a single chain that can be used for other purposes. The logging chain actually looks more useful than the trucker chains I was looking at with 2 different size hooks. So maybe that's a win there, Ill check TSC and online. Ive seen the HF chain supporting massive loads but when i was at the store the links were too thick to slide on the hook, so that seems like a no go.
So i would say there are about 5-6 bushes or whatever the heck they are and i think the tractor could handle 2-3 of them. The others I doubt it, I forgot to take pictures again today dangit, swamped with work other duties.
The jackall jack seems to be the same mechanism as a farm jack yes? I might see if these are available for rental anywhere as I cant see a use case after this is done. Feel free to correct me on this, always looking for excuses to convince the Mrs.
So I've pretty much decided that digging around the base and chopping any possible roots is a must no matter the size just to be cautious. Will chopping these roots dull an axe quickly? I ask because you stated to use a dull axe, I have an 8lb maul but its brand new, Im downing trees next week and will need to split for firewood. Just wondering here. Other than that Ive plenty of spades and a pickaxe.
Thanks for the response, I'll be posting pics tomorrow, most of you are going to LOL and tell me to get a chevy 2500.
