I've replaced both small boards, made new clips for both, new microswitches in the throttle, new fuse board, 2 new reverse relays and new brushes in the main motor.
All this has given my tractor a new lease on life, but now I should be starting to research for a new set of batteries. Any suggestion regarding one brand/manufacturer over another?
Thanks,

The E15 is really being weird: Main motor is now giving me grief,
doesn't start sometimes but will start if I whack it with a wrench. I
see 38 volts at the studs, so I am guessing the brushes are out.
Drat. Parked it, will drop the motor next weekend or so.

Verify field control and wiring before doing anything
rash. ESPECIALLY if it is a Field Reversing control.

Trojan is considered one of the top brands, but they tend to be expensive.
I've had mostly good luck with US Battery, which are more mid-priced, in
road EVs.
I didn't get very good service from
Johnson Controls batteries, but that was
over 25 years ago.
That said, an ET isn't a really high-stress application, certainly much less
so than road EVs, so I don't know that it's all that critical.

Yep, I checked that. Field is actually ok, problem is the motor itself.
Oh well, just drop motor, open the back, clean it out....
In the meantime I noticed one of the deck motors was clanking and
running slow so I opened it up. Yep, magnet came loose. Yep, magnet
cracked. Yep, motor go in trash can. I thought I had a spare large style
mower motor shell but it turns out I have half a dozen small motor
shells. Apparently the magnets come loose on the large shells, and the
armatures short on the small
shells.
I wonder though WHY PUTTING IT IN STORAGE WRECKS MOTORS? I store the
deck vertically against the wall because I don't want it to rust
outside. But for the past 3 years now I have had to replace 1-2 deck
motors every spring. I have no clue as to why...
Maybe I should just leave it in the weeds.

I've seen brush holders corrode from
moisture in my garage and barn during
winter storage. This caused the brushes to bind.
I suppose something similar - say, rust on the inside of the motor housings -
could be causing your magnets to break loose from the housings.
I've been wondering for a while how practical it would be to adapt motors
from 36v push mowers for ET decks. Examples:

http://www.ereplacementparts.com/motor-assembly-p-1106816.html
I'd be surprised if these motors were as stout and sturdy as the original GE
motors.

Now that there are a few 36-volt mowers on the market (Worx, B&D, Toro,
Earthwise, Sears), I'm thinking about waiting for a couple to arrive in
my life (due to dead batteries) and rigging up a front attachment to
drive those from an ET. (Currently I push a 24-volt hand-me-down relic
which just needed a better charger and 2 replacement wheels - still on
the original batteries which have 2004 stamped on them. But I don't
have much lawn to mow.)

Hi HankBuy Trojan T105 batteries and add a Landis controller.Check the
web for the best price on Trojans.My Trojan pack is 7 years old and going strong.The Landis controller keeps the pack charger and eliminates the old style timer.Thanks,Paul Holzschuher?C-185
