The brush grubber or the choker chain brush puller are the least expensive of the options and a shear woukld be terribly expensive to rent for a very small lot.
you will probably be money and agravation ahead by buying a 12 volt winch
using the kubota for the 12 volt dc power, chaining the winch to the tree trunk using a shakle sided for the winch and chain that is cinched tight.
and use the winch and the choker with a very safe way to do it from a central location in the area you want to clear. the cable will pay out freely and the choker will do its job as long as the choker has tension and can maintain the tension. The grubber is the scizzors and it needs a quick yank to dig in the teeth and hold.
The other option is a chain come along and ratcheting out the saplings with the choker and a length of chain.
dont bother with any of the available straps as they will slip
You would get more year round use out of a 12 volt heavy duty winch than the chain come along too I think as you could pile the firewood on a car hood and safely bring it down from where you are cutting.
I would have no idea what a chain come along of five tons capacity would cost from mcmaster carr but the problem of only using it once for this job is another issue-perhaps you could sell it in the swap sheet or craigs list after its all said and done
The winch would see more year round use and the majority are able to be mounted using automotive hitches on your tractor.
The winch could make quick use of a sheave block for the cable to increase its pulling power with much less effort on the winches part.
The sheave or sheaves would create additional mechanical advantage for the winch with low amperage loading on the winch motor.
chaining sheave blocks to larger trees would allow a longer pulling distance for safetys sake also as very liitle effort will create huge amounts of pulling energy and the sheave blocks will eliminate any cable damage and allow a smooth pull at all times.
