3. A frontless option allows you to customize the machine to fit your operations applications.

    
1. The log loader configuration is ideal for truck loading, Butt-n-Top loading, power clam applications and mill yard work.
    
2. An under-mounted heel cylinder provides maximum force for shovel logging with a Cat grapple. A variable displacement pump delivers high-flow rotating capability for heel and log grapples and Power Clam and Butt-n-Top grapples.
    
3. An overmounted heel cylinder provides maximum clearance to load trucks and increases lift height for millyard applications.
