Was plowing the garden with my '78 446. Everything was going good until the very end..... After plowing, I was running the tractor down the road to throw off some of the mud. Right before I turned back into my driveway, I heard a CLUNK and lost most of the power to the engine. It was still running, but not enough power to move the tractor up my inclined drive. It finally died and I can't get it to start again. It's too late tonight to tear into it, but I fear the worst :sad:
