This is Stihl's HTA 135 pole pruner tackles trimming overhead branches with the commercial-grade power and durability of its gas-powered counterparts. It also provides users with the quiet performance and zero exhaust emissions of battery-powered equipment. Featuring a similar durable and field-proven magnesium gearbox to that found on the gas-powered HT 131 and the same shaft as the HT 135, the HTA 135 delivers the cutting performance you have come to expect from STIHL. And its balanced design and ability to quickly and easily extend up to 13 feet helps minimize operator fatigue. With a host of professional features, such as brushless motor, translucent bar and chain oil tank, the included foot mount, onboard battery slot, and variable-speed trigger, the HTA 135 is a true force for pros and demanding homeowners alike.
