Care to elaborate? By my understanding, they tried to use the rear end from an M, and it would blow apart from looking at it wrong.
When that was sorted out, I thought they were great tractors though? I'm a JD guy mainly, so maybe I'm missing something.
Head gasket issues. They didn't have enough head bolts for the head. Which led to head gasket failures. I think later on they changed the number of head bolts.
The trans is lighter to. I think it was also the M trans.
A 560 gas is a lesser evil. No engine problems, no as much power to break the trans/ rear. But still not heavy enough out in the field.
Grandpa had bought a brand new 560D with loader. It was in great shape with low hours went it burnt up in a round barn fire in 81. No one was that upset about it. Other then it was still a nice tractor. It was middle of winter below zero morning. Barn was smoking pretty good already and it wouldn't start. There was a 460 gas dad had so he hooked it up and drag the 560 out. But the barn hill was icey and the loader was down. The 460 didn't have enough weight to pull it out.
Every thing else on the farm was diesel. ( Nothing plugged in)
The neighbor had a 806 gas that dad thought would have enough weight to yank it out.
So he ran to get it and by the time he got back the barn fire was too hot to get close enough to hook the chain.
The 560 was gone. Dad say he watched it fall through the floor a few minutes later, as the fire department arrived on scene.
They ended up letting it burn out. 560 gone, 20 or so Holstein calves gone.
Dad was milking cows in a barn up the road, so he was just using the round barn for young stock as the time.
(Dad figured any calves were dead or if they were still alive, they would die later on from the smoke, so he focused on the tractor instead)
