Zero turn radius mower with cutting blade control
A zero turn radius mower including a pair of rear drive wheels, a mowing deck including multiple cutting blades, an electric storage battery, a pair of electric wheel motors each operable to rotate one of the rear drive wheels, multiple electric blade motors each operable to rotate one of the multiple cutting blades, and a master controller in communication with each of the pair of wheel motors and the multiple blade motors. The master controller is operable to control a rotational speed of each of the pair of wheel motors and the multiple blade motors. The master controller is operable to stop rotation of the cutting blades when the wheel motors are operating below a threshold speed.
1. A zero turn radius (ZTR) mower, comprising:
a pair of rear drive wheels;
a mowing deck including a plurality of cutting blades;
an electric storage battery;
a pair of electric wheel motors each operable to rotate one of the rear drive wheels;
a plurality of electric blade motors each operable to rotate one of the plurality of cutting blades; and
a master controller in communication with each of the pair of wheel motors and the plurality of blade motors, wherein the master controller is operable to control a rotational speed of each of the pair of wheel motors and the plurality of blade motors and wherein the master controller is operable to stop rotation of the cutting blades when the wheel motors are operating below a threshold speed.
2. The ZTR mower of claim 1 , wherein the master controller is operable to receive user inputs and to control the rotational speed of the pair of wheel motors based on the user inputs.
3. The ZTR mower of claim 1 , wherein the master controller is operable to adjust the rotational speed of the blade motors based on the rotational speed of the wheel motors.
4. The ZTR mower of claim 1 , wherein the master controller is operable to adjust the rotational speed of the plurality of blade motors separately such that the cutting blades selectively rotate at different rotational speeds.
5. The ZTR mower of claim 4 , wherein the plurality of blade motors include a first outer blade motor and a second outer blade motor positioned on opposite sides of the mowing deck, wherein the master controller operates the first outer blade motor at a higher rotational speed than the second outer blade motor when the mower turns in a first direction and operates the first outer blade motor at a lower rotational speed than the second outer blade motor when the mower turns in a second direction.
