The RMA 453 PV self-propelled, variable-speed push mower features the state-of-the-art, mono-comfort handlebar which provides strength and stability while also allowing for convenient access to the grass bag, easy height adjustment, and compact, foldaway storage. The integrated mulch flap is easily engaged with the flip of a switch, eliminating the need for a separate mulch plug. The polymer grass bag with directional venting reduces dust exposure for user. Compatible with AP System batteries and capable of sequential discharge of two onboard batteries, the RMA 453 PV offers powerful performance and run times featuring three power modes for increased efficiency depending on the application. ECO mode optimizes battery use, standard mode adjusts RPMs for grass resistance, and auto boost raises RPMs to compensate for resistance. Users can adjust for speed and mode as well as keep track of battery life with the at-a-glance HMI control panel.
