John Deere Worksite Pro GR84B Rock GrapplePremium
🟢 Standard Flow
View on deere.com →
Overview
The GR84B is John Deere's 84-inch rock grapple — a wider version of the GR72B designed for large-frame skid steers and CTLs doing high-volume land clearing, large site cleanup, or commercial demolition debris work. The wider opening capacity means fewer grabs to clear the same area, which matters on big acreage clearing and commercial jobs. Weld-in serrated cutting edges and high grapple forces remain the same as the GR72B. Canadian contractors clearing standing timber or large rock piles will use the GR84B where the additional width justifies the larger machine requirement. Available in Canada through Brandt.

Is This Right For You?
✅ Buy if…
- You handle large boulders, rip-rap, or irregular rock that a bucket can't safely grip
- You work in quarrying, shoreline work, or heavy land clearing
⛔ Skip if…
- Your rock is small and uniform — a rock bucket moves volume faster
- You need to sort debris — a grapple with fingers works better for mixed piles
🔍 Also consider…
- Industrial grapple for mixed debris with some rock
- Rock bucket if you're loading and moving more than sorting
🔧 Machine Compatibility
Compatible with compact track loaders and large-frame skid steers (S750+ class). Verify your machine's rated operating capacity (ROC) before ordering.

Care & Maintenance
- Grease all pivot points every 8 hours of operation — this single habit extends service life more than any other maintenance step
- Inspect tines for bending or cracking after use in rock or demolition debris — bent tines cause uneven closing force and can fail under load
- Check hydraulic hose connections and fittings weekly — grapple hoses take more abuse than most attachments due to constant jaw cycling near rough material
- Inspect cylinder pins and bushings monthly; sloppiness in the jaws indicates worn bushings, not just general age — replace before the pin starts wearing the bore
- Store with jaws closed to reduce stress on the frame and keep the hinge pivot pins from accumulating debris
