I am looking f or a PTO shaft for the tiller. Part # 52448404. This is a 1984 model tiller and the best price I can find is $150 for the shaft. Any help for used or better pricing?
Certainly you can look for generic shafts, if you know the min/max length, and which type of ends. But a buck-and-a-half doesn't seem too outrageous; I doubt you'd save even fifty bucks.
You need to be certain to get a pto shaft with a shear bolt to avoid smashing the guts out of the tiller gear box.
The shear bolt end of the pto shaft should be at the tiller gearbox end and not the tractor end.
Whatever you buy, you want to be certain you can get parts for it as they don't last forever.
Having outer guards on the shaft is like having a seat belt or a roll bar, you don't appreciate them until the fraction of a second before you need them.
The more angle there is on the joints the short life that shaft will have as this graph shows.
A joint angle of 5 degrees results in a pto joint life of 450 hours. Increase the joint angle to 25 degrees and the life is only 20 hours.
Having a longer pto shaft lessens the joint angles and thus increases the pto shaft life
