Well you are certainly correct about pushing the envelope. I hadn't realized the trailer was loaded? But, I forever surprised what these
little tractors can accomplish. I use the nylon slings, tie downs, lifting and towing straps from 1" to 4 ". I can't tell you the number of
saplings that have lost there life . to a yellow strap connected to a yellow cub. A neat set up was a 30 ft i in. strap my friend made up for me.
It has a loop on one end that goes over a trailer ball on my draw bar. The other end has a hook and in between a sliding steel ring. I lay out the strap and lay out tree limbs I've cut on top of the strap butt end towards the tractor. Cinch the hook in the sliding ring, the loop over the trailer ball, where you backed the tractor.
Put 'er in second and drive off. I've moved brush, limb piles, old boards. etc. I 've even drug some pretty big pines with a hook in the lift arm and raise the trunk just enough so it won't dig in. Sometimes if the limbs are big enough it will just kinda float if balanced correctly. Next time I'll post some pictures.
