I have to agree with GERRY on the old fashioned "L" shaped NEW allen wrenches for busting those six PTO setscrews loose. And lots of PB Blaster, Kroil, Liquid Wrench, home-made Acetone/ATF, whatever your favorite rust-buster is. Then coat the screws with Anti-sieze when you put it back together. Makes future disassembles MUCH easier.
STEVE B. - Week ago tonight I was watching an older Coffin-nose Magnum pushing 5 inches of new snow around our parking lot at work. FWA, duals, no chains, BIG 12 ft snow blade on the frt. 7150, 7250, 8950, maybe a smaller HP rating. He was having NO HP or traction issues. Kinda envious, I could see into the cab well enough to tell he had the sleeves on his flannel shirt rolled up, no coat/jacket, but couldn't make out the model looking into the flood lights around the parking lot 250 ft away.
When he'd power-shift from 13th, 14th, or 15th gear forward into 4th reverse, sure a LOT of clunking going on in the trans. The neighbor's MX-180 & 200 don't make those noises.
Have to laugh, neighbor across the road chisel plows with a green 4955 and a 2-shank too big chisel plow. Neighbor with the MX-200 uses a smaller plow and actually covers more acres per day/hour, and doesn't have to run 2000# of suitcase weights below the back window of the cab to get traction.
I've watched the neighbor behind me farm for 20+ yrs, seen everything from a Farmall 300, M, 706G, 1486, 3588, 5288, couple newer Magnums, now the MX's run. Used to enjoy falling asleep 15 yrs ago listening to the DT466 in the 3588 chisel plowing.
Bet he mows with an IH CC too!
A power-shift of some sort would be better than a full hydro for draft loads. Today's designs reduce the parasitic power loss and heat build-up of the early P/S trans. And they're durable with wet clutches. But finding a trans small enough with enough gears for a CC would be hard. A hydro is probably the best alternate. But I'm still partial to GD's.
