dvanced Structure © The speed change gearbox is standard on all models wh ch give high torque output for cutting. There are two types of gearboxes for your choice, which are the type of two speeds with auto Hi-Lo steps and the type of auto 4 speeds. They handle heavy duty cutting with ease and offer proper speed range for light and medium cutting as well. There are also two opt onal gearboxes for your choice, wh ch are 4-speeds Bult-in type and 2-speeds ZF gearboxes.
