1. A battery-powered lawn mower comprising:
- a deck supported by wheels on a first side;
a cutting mechanism having a first motor including a first output member;
a first cutting blade driven by the first output member;
a self-drive transmission having a second motor that selectively communicates an output to a drive axle; and
a force feedback controller that measures a load on the first motor and changes an output voltage to the second motor based on the measured load.

Abstract
A battery-powered lawn mower includes a deck supported by wheels on a first side and a cutting mechanism having a first motor, including a first output member. A first cutting blade is driven by the first output member. A self-drive transmission has a second motor that selectively communicates an output to a drive axle. A force feedback controller measures a load on the first motor and changes an output voltage to the second motor based on the measured load.

8. A powered lawn mower comprising:
-
a deck supported by wheels on a first side; a first motor driving a cutting blade; a second motor connected to at least one wheel of the mower for controlling the speed of the mower; and a force feedback controller that measures a load on the first motor and sends a signal to the second motor based on the measured load to vary the speed of the at least one wheel. - View Dependent Claims (9, 10, 11, 12)

16. A battery-powered lawn mower comprising:
-
a battery; a deck supported by wheels on a first side; a drive axle coupled to the wheels; and a self-drive transmission comprising; a motor powered by the battery and having an output member; and a clutch assembly having a driven transfer gear coupled for rotation with the output member, and a clutch cam mounted for rotation with a user input member, wherein an input from the user input member urges the clutch cam to concurrently rotate about and translate along an axis thereby locking the drive axle for concurrent rotation with the driven transfer gear and the motor output member. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
