Thanks for all the responses guys
I was out of town for a day trip over the weekend, and just now had a chance to read all your responses. I really appreciate the ideas. I really liked the Jeep with the hitch hauler. I have a hitch hauler. I'll have to look on line to see if anyone makes a 3 pt adapter for it. That would be one answer.
My 1010 is pretty much identical to the one someone posted. I had a weight rack built for the front end that I can hang MF suitcase weights on. I think they are roughly 35 lbs each, and I have 4 of them, with room for 2 more. With 3 of the weights in place, I can handle a 250 lb core aerator on the 3 point with no issues. So I'm thinking maybe 6 weights and try to keep the load under 500 lbs each trip may work. Maybe I won't have to back up the grade, but if I get enough traction to do this slowly enough, I'd try it.
The trailer I was using is the one I haul the tractor on...it's a 4 x 8 and probably weighs 500 lbs empty. But my loads were maybe 4 x 5 x 12" high on average. I do have a lot of turns in the woods, including a 90 degree turn at the bottom of the hill into the creek bottom. And I have to get around the stumps and trees. The length of the rig is one of the problems. I have lifted the back of it when empty to get it into position for backing up a couple times.
Friday I went down the trail with a leaf blower to move the leaves, and spread a partial load of chips from where we had earlier ground up a bunch of the limbs. That improved the traction. Then when I get to the bottom of the hill with a load, I go to 2nd gear, high range, open the throttle, hit the diff lock, and let out the clutch. It claws up the hill pretty well like that. I have dropped the air pressure on the rears, but may drop it more. I don't have a winch but used a 4 ton cable come-along Friday when I got stuck. That worked pretty well too. I have pulled about 10 loads out of the creek bottom so far like this.
I've been doing some searches on the internet about it, and I think the answer for me may be a 3 pt carry all, lifting a wooden pallet loaded with rounds. If I get stuck, I can set the load down and pull away, or get around the pallet and pick it up from the other end to move it off to the side. I have a pallet in my garage, so I can see how this might come together.
Any other thoughts on this, please post...thanks again for your ideas.
