But is today!
Took the axles out first. Was simply a by the numbers operation. Bolts out, axles on the ground, hook strap to end of axle and other end to tractor and drag out till it hits the frame then dig and move and shift till it comes out. pant and blow a while and do it again. Eat lunch after the second one is almost out. Back out afterwards and dig a while then pull the second one out. same on the third. Jacked the trailer up a bit more and got the sideboards that came on Bertha. Got the grinder and some grease. Ground all the welds and bumps and such that could possibly impede the forward motion of the trailer. After i finished that got the grease gun and coated the top of both pieces. slid them in on top of the log and under the trailer frame. Lowered the trailer onto them so it was resting on those 2 points in the back and the tongue on a sheet of plywood in the front. Hooked the chain up to the frame and to the dozer. Started forward and the trailer moved like it had wheels. Pulled it the entire 7 feet in just a few seconds.
Alignment wasn't what I had thought so I moved the dozer to the hitch end and pushed it over a bit and then a bit more and then some more. got it close there and was over a couple of feet too much at the back now. the other way of course. so to the south side and hooked the chain to the frame close to the wheels and pulled it over a bit. looking good so moved to the front and got up on the bank with the dozer and hooked the chain to the hitch and pulled it forward a couple of inches and then it stuck. got the shovel and bill and I dug and flattened the ground uphill of where it needed to slide. got back on the dozer and after a few jarring lunge and snatch it a inch or so at a time got it moved the required 3 feet. That gives us an entry between the qhut and the trailer.
the alignment is close. not exact by a long shot but close enough for my kind of building.
