527 Track Skidder - Puckett Rents

The Cat 527 Skidder is designed and built specifically for log skidding applications. The 527’s extended track roller frame and weight-forward bias make it well suited for mountainous and soft underfoot logging operations. The skidder’s ergonomic and spacious operator’s environment allow for increased comfort and production. The 527’s standard forestry guarding and undercarriage design ensure the durability required in logging applications. Both Cable and Swing-boom Grapple configurations are provided to suit a wide range of skidding applications.
