2025 John Deere GR84B Rock Grapple 

2025 John Deere GR84B Rock Grapple

High grapple forces, wide grapple capacities, and weld-in serrated cutting edges make rock grapples ideal for tasks such as land clearing, jobsite cleanup, and brush removal. These rock grapples are optimized to work with John Deere skid steers, compact track loaders, and compact wheel loaders. They're also compatible with most competitive models.

Features May Include:

• GR Series Rock Grapples are ideal for a variety of applications

OVERVIEW

GR Series Rock Grapples are designed to be a multipurpose tool for land clearing, brush removal applications, and jobsite clean-up.

BENEFITS

• Each unit includes two independent-action grapples that allow for optimal clamping action when grappling objects with non-uniform sizes such as root balls, large rocks, or demolition debris.
• Open sides on the rock grapple models allow easy grappling of material that is wider than the bucket
• Specifically integrated design features allow the rock grapples to be used for grading a site after debris removal
• Tine spacing allows for material sifting when used in the forward direction
• The bucket heel profile allows for loose material to flow through or for scarifying of surfaces when grading in reverse
• A weld-in serrated cutting edge supports each tine and provides superior material penetration capabilities
• Greaseable and hardened 31.8-mm (1.25-in.) pins with increased cylinder specifications result in improved durability
• An improved hose routing over the previous series grapples eliminates the need for grapple cylinder stops on large frame G-Series Skid Steers
• Increased side cutter, side sheet, and backsheet plate thicknesses, combined with larger torque tubes result in heavy-duty bucket construction for the most demanding applications

• Design improvements

OVERVIEW

Accomplish more with increased capacity and improved design.

BENEFITS

New rock grapple design

• Tines are spaced three inches apart and fully supported on each side for maximum bend resistance
• Weld-in serrated cutting edge easily penetrates difficult ground conditions
• Solid backplate along the Quik-Tatch™ area protects hydraulic cylinder hoses and the machine from debris and damage
• Thickened side cutter, side sheet, and backplate combine with large torque tubes for heavy-duty construction that meets the most demanding applications

Increased cylinder size

• Cylinder size of 63.5-mm (2.5-in.) bore diameter and 35.56-mm (1.4-in.) rod diameter delivers high grapple forces to tackle even the most difficult materials
• Grapple arms feature integrated mechanical stop to reduce cylinder load when open

Improved grapple capacity

• 619.76-mm (24.4-in.) wide grapple arm and range of grapple stances  help grasp broad, cumbersome loads

• Independent-action grapples enable different-sized objects to be picked up with each grapple

Improved hose routing

• Durable 90-degree quick-couplers on the hydraulic cylinder hoses eliminate interference with the grapple
• Standard low-profile cylinder guards simplify hose connections
