Live in a swamp, so no nearby cliff to push it off of.

You could always just push it into the swamp.

Issue resolved, but a tad tedious:
Remove all existing wiring from the mower. except wires from blade motor and Traction motor.
Install and connect generic BLDC Motor Controllers (2). ($60 each)
Add one toggle switch for "Main Power". (Closes contactor to provide power to controllers)
Add two potentiometers for a) Blade Speed, and b), for Mower Speed.
Way simpler, but do so at your own risk. I'm not responsible for anybody else performing these modifications.
