Delimbing starts at first gear , as MultiSpeed provides high torque at a low speed . MultiSpeed is a popular option for the H415 harvester head because it offers the highest possible hydraulic power and feed torque for customers working on sites with large trees and heavy branches .
The higher frame of the H415 helps control the felling process , and the hydraulics solution makes the hoses more durable . Feeding is handled efficiently , due to excellent grip and trunk management features as well as the location of the delimbing knives .
