I haven't used the field weakening in earnest yet, but there is some serious potential there (pardon the pun...)
|Acceleration||pretty good for a 700 lb. tractor. Limited top speed until you activate the field weakening, then it's off to the races....|

typically these can do 2 acres per charge. I have a lot less than that to do.

It's sometimes hard to tell if the mower deck is cutting since the wheels mash the grass flat for a while after they go over it.
|Conversion Time||about a year of weekends and evenings|
|Conversion Cost||Slightly more than a new ZTR, but a lot more fun, too.|
|Additional Features||2000 lb. winch in lieu of factory lift.|
1800W inverter to power standard 120VAC accessories (not yet mounted)
Bright yellow paint job (I always hated the original elec-trak "putrid mustard" color).
|The only thing that takes getting used to is the front mounting of the deck. The shunt motor brings you right to a stop when you turn down the throttle - haven't needed to use the brake yet!|
