Abstract: A deck height control system for use with a mower that has a deck positioned at a first height and is configured to support a blade motor. The control system includes an actuator that may be configured to vertically displace the deck from the first height to a second height. A deck system module may connect to the actuator and be capable of signaling the actuator, during operation, to displace the deck a particular deck distance in a particular vertical direction necessary to achieve the second height. The deck system module may further have a deck height memory capable of storing information relating to deck displacement activity. A control may connect to the deck system module and be capable of signaling the particular deck distance and particular vertical direction to the deck system module when engaged by an operator. A battery-operated mower may include the deck height control system.

Abstract: A cooling backpack apparatus includes a frame secured to a harness with the harness configured for removable securement to an operator. A battery pack having a battery pack enclosure encases a plurality of battery cells. The battery pack is removably or permanently secured at least indirectly to the frame. A cooling fan is secured to the frame and electrically connected to the battery pack. An air input port receives air into the cooling fan, and an air output port permits exit of forced air generated by the cooling fan directly to the operator wearing the harness. An air chute is provided for guiding the flow of air from the air input port to the air output port.

Abstract: A backpack blower having a fan frame with an air inlet and an air outlet. A fan assembly is positioned within the fan frame. A motor rotates the fan assembly to move air out the air outlet. A controller is connected to the motor and to a battery pack, for using power from the battery pack to energize the motor and thus rotate the fan. A harness frame is connected to the fan frame and has an opening in air flow communication with the air inlet, so that, when the motor is rotating the fan assembly, air is drawn in through the harness frame opening. Since the harness frame is positioned in the area of an operator's back when the blower is in use, the air flow drawn in through the harness frame opening has the effect of cooling the operator.
