RMA 443, without battery and charger
Compact, high-performance battery-powered lawn mower
General
The STIHL RMA 443 is the clever choice if you have high standards for the mobility of your lawn mower. Equipped with the high-quality lithium-ion batteries from the STIHL AP-System, the lawn mower has high energy reserves. For economical application of this power, the motor's activatable eco mode offers especially energy-saving operation in combination with the flow-optimised blade. The foldable grass catcher box holds a large quantity of clippings and is easy to empty. So that you do not expend any unnecessary energy either when mowing your lawn, the STIHL RMA 443 is easy to manoeuvre, relatively light and thanks to the QuickFix quick-clamping device can be quickly and space-savingly stored or transported.
