I recently started experiencing "bucking" on my 1997 520-H with the Eaton 1100 series transaxle. This occurred after 500 hours of heavy use with the 60" mowing deck, with all transaxle oil changes performed per specs. In reviewing causes of "bucking", I came across this for a similar complaint in a Simplicity 4711 that used the same transaxle. ( simpletractors.com/forums/topic/7441-simplicity-4211-hydro-bucking-problem/ ). One thought was that this was due to missing or loose bolts securing the transaxle to the frame.
This turned out to be precisely the reason for the "bucking" in mine. One securing bolt replaced, all other securing bolts tightened (along with the engine bolts), and the Forward-Reverse lever/linkage adjusted and tightened, and the tractor is back to "usual".
It's just something to consider before the nightmare of a transaxle overhaul...
Does anyone know where you can get the correct size, 90 deg crimp fittings for the hydraulic line going from under the hydro trans to the lift valve on the 520-H? I found a Gates fitting with the correct thread size but it was too long on the thread end. It came down too far under the transmission to allow the hose to come over the frame.
Hopefully I described this well enough?

Problem # 1
Last winter Noticed that the Drive Pully on the Blower was wabbling
This spring when I took the belt off I noticed that the Keyway on the spindle and pulley was worn.
The Key ways actually rounded
The set screw in the pully to spindle was missing.
So, what is the easy/cheap fix that will solve this issue
Thinking of mig welding the pulley to the spindle.
How Stupid is that idea?
The scraper Blade is well worn. Should I try to find a new piece or weld something to it?
What would you guys do?
Thanks In Advance for taking the time to Respond,
