The common failure on the Peerless transmission is the input shaft.  The
input shaft, which is not hardened, rides directly in a needle bearing.
When the transmission is old or if someone goes gorilla on the belt tension
the input shaft wears and no longer rides in its proper position.  If it is
that noisy, repair it before more damage is done.  As the Peerless
transmission (Peerless now owned by Tecumseh) was used in many no GE
tractors, transmissions and rebuild parts are available.  My local John
Deere dealer is also a Tecumseh/Peerless dealer.

My guess is that the grass will stand up to be cut despite the presence of
bands.  Remember that there are two chances to cut the grass as the deck
passes over your lawn.  I have converted my deck to side discharge.  With
heavier cutting I got clumps with the rear discharge that I don't get with
the side discharge.  There is a different band available for side discharge
that just bolts on.

If you were to have a catastrophic failure of the charger it would be nice
to be able to disconnect the charger from the batteries.  That is probably
why GE did it that way in the first place.
