An outdoor power equipment device, such as a lawn mower, includes a main chassis having first and second pivot joints, a first rocker arm having a caster wheel on a first end portion and a drive wheel on a second end portion, and a second rocker arm having a caster wheel on a first end portion and a drive wheel on a second end portion, wherein the first rocker arm and the second rocker arm are independently pivotally coupled to the respective first and second pivot joints of the main chassis at a location between the caster wheels and the drive wheels.

A portable heater includes a housing having an air inlet and an air outlet, one or more burners housing within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a duct positioned in a storage compartment of the housing. The duct includes a first end coupled to the storage compartment and a second end extendable from the housing when a door of the storage compartment is in an open position.

Towable heater

A portable industrial heater including a housing having an air inlet and an air outlet, one or more burners housed within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a generator selectively providing power to the one or more burners. The air inlet and the air outlet are positioned on a same side of the housing.

An autonomous lawn mower includes removable batteries, one or more electric motors, a cutting blade, one or more wheels, an angle sensor, and a controller. The cutting blade is driven by one of the electric motors. The wheels are driven by one of the electric motors. The controller is configured to allow the lawn mower to perform a grass cutting function at a jobsite without human interaction. The controller is configured to determine whether a roll angle is greater than a first predefined amount using data from the angle sensor. In response to determining the roll angle is greater than the first predefined amount, the controller is configured to stop operation of one of the one or more electric motors configured to provide rotational drive power to the cutting blade.

Systems and devices for lawn care

A ride-on vehicle, such as a zero turn radius lawnmower, includes a main chassis having first and second pivot joints, a first rocker arm having a caster wheel on a first end portion and a drive wheel on a second end portion, and a second rocker arm having a caster wheel on a first end portion and a drive wheel on a second end portion, wherein the first rocker arm and the second rocker arm are independently pivotally coupled to the respective first and second pivot joints of the main chassis at a location between the caster wheels and the drive wheels. The ride-on vehicle may also include a modular mower deck assembly with a plurality of mower deck modules having a blade assembly, an electric blade motor configured to provide rotation to the blade assembly, and an attachment assembly configured to enable attachment between adjacent mower deck modules.

Modular mower deck for use with a lawnmower

A system for providing autonomous lawn care services. The system includes a number of autonomous outdoor power devices, and one or more service vehicles. The one or more service vehicles are configured to selectively load and unload one or more of the autonomous outdoor power devices at a jobsite based on instructions received by a controller of the one or more service vehicles.
