Find the Right Attachment for Your Machine

Enter your machine's rated operating capacity, hydraulic flow, and primary job — get attachment recommendations with width ranges and flow requirements specific to your setup.

Your Machine

Tell us about your machine so we can match you with compatible attachments. All recommendations are based on real machine class and hydraulic engineering specs.

CTLs generally have better traction and hill stability. CULs (stand-on) are limited to lighter attachments.

Check your machine's spec plate or manual. ROC is listed at 50% of tipping load.
High flow is often a factory option — check your spec sheet, not just the model name.

Attachment Recommendations

Note: These recommendations are based on typical machine classes and manufacturer specs. Always verify compatibility with your specific machine model before purchasing — flow requirements, coupler compatibility, and weight limits vary by make and model year. Ratings assume standard Canadian conditions unless noted.

How to Read Your Machine's Specs

Rated Operating Capacity (ROC)

ROC is 50% of the machine's tipping load and is stamped on the spec plate inside the cab. It's the maximum weight you should lift at full reach. Attachment weight counts against your ROC — a 600 lb grapple on a 1,500 lb ROC machine leaves only 900 lbs for material.

Hydraulic Flow (GPM)

Your machine's auxiliary hydraulic output in gallons per minute. Standard flow: 14–18 GPM, on virtually all machines. High flow: 22–30 GPM, typically an ordered option that must be enabled. Ultra high flow: 30+ GPM, available on specific large-frame models.

Machine Classes Explained

  • Compact (<1,000 lb ROC): Bobcat S70, Case SR130, Kubota SSV65
  • Mid-frame (1,000–1,750 lb): Bobcat S650, Case SV340, Kubota SVL75
  • Large-frame (1,750–2,500 lb): Bobcat S770, JD 332G, CAT 299D
  • Heavy (>2,500 lb): Bobcat T870, CAT 299D XHP, JD 344L

Width Selection Logic

Attachment width should not exceed your machine frame width by more than 6 inches. Wider attachments reduce breakout force and operator visibility. For high-production work, match width to your lane width, not your machine's maximum capacity.

Hydraulic Flow Reference

⚪ No Hydraulics Required 🟢 Standard Flow (14–18 GPM) 🟡 High Flow (22–30 GPM) 🔴 Ultra High Flow (30+ GPM)

🟢 Standard Flow Sufficient

  • GP buckets, rock buckets (no hydraulics)
  • Pallet forks (no hydraulics)
  • Snow pushers — basic (no hydraulics)
  • Grapples — standard aux
  • Augers — standard drive units
  • Angle blades, snow blades
  • Brooms, soil conditioners, power rakes
  • Post drivers, cement mixers
  • Landplanes (no hydraulics)

🟡 High Flow Required

  • Rotary cutters (18–30 GPM)
  • Flail mowers (18–30 GPM)
  • Stump grinders (15–35 GPM)
  • Chain trenchers (18–30 GPM)
  • Rock wheel trenchers (25–35 GPM)
  • Hydraulic breakers — large class
  • High-torque auger drives
  • Snow blowers — large (22+ GPM)

🔴 Ultra High Flow Required

  • Drum mulchers (25–45 GPM)
  • Disc mulchers (30–40 GPM)
  • Cold planers (30–45 GPM)
  • Forestry cutters — heavy class
  • Production stump grinders

CUL (Stand-On Loader) Limits

Compact Utility Loaders (Dingo, Boxer, etc.) typically have ROC of 500–1,200 lbs and standard flow only. Avoid: mulchers, large rotary cutters, heavy trenchers, heavy stump grinders. Suitable for: light buckets, small augers, post drivers, small brooms, landplanes, small grapples.
