Re: (ET) Coasting with E20

One other thought: Without power, the motor does not present much of a drag
load to slow an E-20 down. In fact if you're going down a hill with the
tractor in L or LL, you *CAN* wind up overspeeding the motor and wrecking

Solution is simple: Drive down the hill with power.
