I have changed the drive belt on my HR 42" a few times, it has been getting thrown off the damn pulleys and breaking.
Anyway changed the drive belt again on Sunday drove the damn thing 10 yds and the belt come off again.
Going to replace the idler arm spring first; I changed the idler pulley on Sunday.
Then I saw a vid on you tube and I think one or more of the pulley cooling fan fins? is bent! and hitting the belt throwing it off the pulleys.
So do the pulleys need those cooling fins I assume they cool the transmissions? or are they speed fins?
If not I will try to cut the fins back a bit.
If they are needed I have to drop the transmission units to change the pulleys.
So there is me and a floor jack... how do the transmissions come out of the mower!
Any answers would be gratefully received.
:ashamed:
