The EcoPro Series Firewood Processors’ manual saw arm can be replaced with the Range Road RR2540 Hydraulic Saw Arm Kit, which provides hydraulic control of the chainsaw. It is driven by the processor’s hydraulic system and controlled by the operator of the processor. This kit is ideal for those who have difficulty operating the manual saw arm to cut firewood. However, we do not recommend the RR2540 for those seeking to increase production on the EcoPro Series Firewood Processors. The RR2540 kit includes a hydraulic cylinder, valve bank, required hoses, and fittings. The RR2540 can be used in conjunction with other EcoPro Series Firewood Processor Accessories, such as the RR102, RR103/RR104, RR106, or RR2521.
