The Yard Force YF120vRX 18” line trimmer with push button speed control has the power and control for all your trimming and edging needs around your yard. The convenient push-button start has 3 speed settings to give you the control to match every trimming and edging application. The motor and cutting head are perfectly balanced on the ends of the shaft to save energy and provide greater control. The trimmer head uses standard line up to . 095” that is easy to refill with the quick-load spool without taking the head apart. The bump-feed head keeps the 18” cutting swath at full capacity. The YF120vRX Lithium-Ion product group produces the power, torque and runtime of gas powered products without the mess, smell, maintenance and hassle of a gas engine. The advanced cell design of the high capacity 120v / 2. 5 Ah battery powers these tools right through the end of the charge without any “drop-off” for consistent power and the 4 Amp fast charger gets them back to full charge within 30 minutes. All products in the Yard Force 120vRX Series use the same battery for convenience and ease-of-use.
