Remote-control slope mowing system with inclinometers and safety features

A system, comprising:

• a mower having:
• an engine selectively coupled to mower blades via a power takeoff (PTO) unit,
• a first inclinometer,
• a first antenna, and
• a first controller coupled to the PTO unit, the first inclinometer, and the first antenna;
• and
• a remote handheld unit having:
• user input device(s) with which a user can issue commands to remotely control the mower,
• a second inclinometer,
• a second antenna, and
• a second controller coupled to the user input device(s), the second inclinometer, and the second antenna such that the second controller wirelessly communicates with the first controller;
• wherein the first and second controllers cooperate to control operation of the mower based on both a condition of the first inclinometer and a condition of the second inclinometer.

A method of operating a mower system that includes a mower and a remote handheld unit coupled wirelessly to the mower to control the mower's operation, the mower having a first inclinometer, a first antenna, and a first controller, the handheld unit having a second inclinometer, a second antenna, and a second controller, the method comprising:

• communicating a first tilt angle of the first inclinometer to the first controller;
• sending a wireless signal from the handheld unit to the mower, the wireless signal indicative of a second tilt angle of the second inclinometer;
• communicating the second tilt angle to the first controller;
• and
• controlling operation of the mower with the first controller based on both the first tilt angle and the second tilt angle.
