I've always given my B2601 mower a pretty hard time - I mow some rough pasture sometimes. That can overload the mower, which I did again the other day. I had a big clump of grass got stuck, which then caused one of the blades to spin on the spindle (accompanied with some smoke).
I've dismantled and reassembled the blades, one of them spins reasonably freely (i.e. when you turn the blade by hand, it spins rather than forcing the pulleys around - so not much friction at all).
They look to be a friction fit - there's a spline onto the spindle, but the spline isn't keyed onto the blade itself, so the blade can spin between the washers, the cup that covers the spindle, and the face of the spindle.
I dismantled again and swapped the bolt, the cup, the washers and the blades around between the spindles, it's better but it's still a bit loose.
In theory I think I could improve this by just adding a bit of thickness - another washer, or even some paint between the washers to give it a bit of stickiness (it seems they've worn very smooth and frictionless). But the better answer is probably replacing some of the parts - the question is which ones.
Has anyone had this problem before / have a view on how best to resolve it?
My logic is that it's actually made to spin when it has to - otherwise it'd have to force the pulleys to spin under the belt when the blades jam, which would be more damaging.
