Good morning,
I got my old IH sickle mower working and cut several acres of hay with it. It worked great.... until I ran into some very heavy grass with it. The slip clutch started slipping, I stopped the tractor, cleared out the grass by hand (not the first time I'd done that) and drove the tractor into a clear area which had already been mowed and raked. When I engaged the PTO, the slip clutch started slipping again....
The bar is tightly bound up. I have disconnected the pitman arm and the gearbox and arm and pto shaft turn easily by hand. The sickle won't move. I pulled off the hold downs closest to the pitman and that lets the bar move, but not easily.
There's nothing jammed up under the cutter, nothing is visibly bent or broken... it just won't move past a certain point.
There is an elaborate mechanism attached to the bar and the lift lever which I'm afraid I do not understand and therefore don't know how to troubleshoot.
I've searched all over (over an hour of googling now...) and searched for pictures and diagrams, no luck. I'm not certain of the model, some say 25v, some 27v, others say, no, not either of those...
Any suggestions much appreciated.
Thanks.
John
