broke my tractor , battery was spent so we tried to pull start it. i was in the truck my son on the tractor. tractor was in low gear he poped the clutch, engine didn't start. so we went to the shop and got the cables and jumped it. it fired right up. but now it willn't engage the transmission . my son said there was a funny noise when we tried to pull start it. how much damage ya'll think we did and to what clutch, trans input shaft ,trans output shaft . i'm hoping we just striped a coupler. what do you think all response will be greatly appreciate.
