hi Paul, the Ariens mowers where not a great sucsess in Oz and where only imported
for a few years, they would have worked great in USA but most sucummed to harsh
conditions here, very few if any would be still self driving, and not many will still have
the swivel wheels in tact..
the self drive is a friction disc type with a massive horizontal drive disc that was supported by a centre
bearing that would collapse making the friction wheel, that is a smaller vertical wheel, not making contact.
if you look behind the motor above the deck you will see what i mean, if there is play in either discs
then there will be no drive, good luck mate,
ps, i have an original sales brochure for them!! sad i know
