Like the Rhino® GPD-30 Ranch Pro™ and GPD-40 Fence Pro™, it is powered by a Honda 4-cycle engine, but the GPD-45 Multi-Pro™ has been engineered with increased driving dynamics needed to drive larger posts and versatility to take on more post driving applications. The design includes ergonomically balanced cushioned grip handles, Rhino® CIS™ anti-vibration dampening, Rhino Tension Grip™ crankcase cover for fast inspection and maintenance, and the Rhino® Chuck-Lok™ Adapter System that allows the operator to quickly install post adapters in the field, ranging in application from 1? to 2-3/8? round posts. The GPD-45 Multi-Pro™ versatile external chuck design can be configured with optional chuck and anvil for driving 1.2-4 lb channel post, tent stake chuck, concrete form pin chuck, or 1-3/4? to 2-1/2? square sign post and square post sign anchor with a drive cap.
