bought a new(to me) branson but still got the old ford 4000(1973?, ind. pto). needs some work but will crank and run. the pto shaft seal leaks again after i paid someone to put it in after i couldn't shaft back in. the thrust washer whipped me. i believe the inside snap ring has broken again but the shaft is still in place, i'm just not gonna use the pto for now. is there a fix for this? implement shaft telescopes properly, although bush hog does have vibration. if not i may just use it with non pto implements. seal doesn't leak bad when pto not turning
