(ET) Wheelhorse E141

The E141 was a Wheel Horse only design based on a gasoline tractor chassis.
It used as delivered six 12 volt batteries, wired in a series/parallel
arrangement to give 36 volts.  Bill Gunn once theorized that Wheel horse 
did
that because at that time the six volt EV batteries were being supplanted 
by
the 12 volt types.  Of course, the six volt EV battery is still with us.
Unfortunately the use of 12 volt batteries gave you twice as many cells to
top off with water, and created the possibility of charge imbalance during
charging.  It also used a Wheel Horse supplied off board charger.
 
The E141 used a single speed traction motor with either a seven or eight
speed shift on the fly transmission, which I believe was Wheel Horse
designed .  Reverse was also by the transmission.  This transmission was
also used on some of the Wheel Horse gasoline tractors.
 
The mid mounted mower deck used a single large electric motor with belt
drive vs. the GE three motors on a front or mid mount (E12-M).  This made
the deck almost identical to the gas powered decks, although the electric
deck could not be supplied with a grass clipping bagger, where the gasoline
versions could.  I suspect a power limitation in the electric motor not
present in the gasoline powered tractor.

quick question.  the e-141 doesn't look anything like the elec-trak and the
add read needs 6 12v batteries......  did the seller mean 6 6v batteries or
is this tractor running 72 volts.
