The improvements also include in increased power-to-weight ratio, an improved engine after-treatment system, and new grapple and boom options.
The upgrades to the engines increase power, providing customers with more pulling power and faster multifunctioning capabilities. The L-Series Skidders now have a simplified engine after-treatment system. Redundant temperature sensors have been removed, reducing harness complexity. The updated models now have a single temperature module, simplifying troubleshooting. Harnesses have been rerouted, improving access and reliability, and have more secured points to reduce rubs. Additionally, the Diesel Particulate Filters regeneration interval levels have been increased from 50 to 100 hours, reducing fuel consumption.
The L-Series models now also have an extended boom reach option. Designed for steep or uneven terrain, the longer booms increase lift height and improves rearward and downward reach. The new booms also reduce interference with the arch and fenders during turning and contact of tongs on tires and fenders when rotating the grapple. The skidders now have a 17.5 square foot (1.63 square meter) grapple option for all dual function models. This new grapple size increases productivity in thinning or heavy load applications. On the 648L the grapple will help to save time and fuel by reducing the number of trips needed in dry wood and thinning applications.
The L-Series skidders now have a cab with 25 percent more space and is 50 percent quieter. It includes fatigue reducing aspects such as the HVAC system, ergonomic controls and storage space. An optional rotating seat with joystick steering helps reduce strain on the back and neck. The updated L-Series Skidders are now available in North America. Source
