Re: (ET) Reliable, heavy-duty electric tractor?

How about an E-15 with an Alltrax controller upgrade? This would make it
far more reliable than the original relays and circuit boards. The
mechanicals are pretty solid (except for the mini-brake). It may be a
sacrilege to this group, but I use a 14 hp DR brush hog, an old Gravely
walk-behind, and a 40HP John Deere utility tractor with PTO drive brush hog
to mow trails. By my standards, the front deck on the 15 and the mid deck
on the 12 are certainly not trail mowers, nor do I know of a tow behind
electric trail mower. Swisher makes some powered tow behind trail mowers
for ATVs and garden tractors that could be used as trail mowers (if you
don't have an objection to a gasoline engine in tow).
For simplicity I would recommend a straight E12. Very basic speed
control, no worry about field weakening, no electronics more complex
than a pair of diodes (replace), and the frame/body/motor of E15/20 caliber.
However I think the deck would disintegrate if used heavily on things
like trails. The wheels are not up to it, nor are the wheel spindles. As
well the deck itself would need reinforcing.
