John Deere Worksite Pro RC78 Rotary Cutter
Overview
A 78-inch rotary cutter in John Deere's Worksite Pro line. The RC78 is the widest option in the Worksite Pro cutter range — broader coverage per pass for larger-scale field and brush work. At 1,666 lb it's matched to large-frame high-flow skid steers and CTLs. Double-edge blades and a rigid quarter-inch steel deck handle hay, brush, and saplings up to 4 inches in diameter. Includes blade-stall indicator, front chain shield, and standard stump jumper for gearbox protection on hidden obstructions. Available through Brandt.

Is This Right For You?
Buy if
- Your skid steer runs 25+ GPM high-flow hydraulics and you need maximum cutting power for heavy brush
- You're land clearing or maintaining overgrown acreage where standard-flow cutters bog down
- ROI matters — a high-flow cutter clears more per hour than a standard model on the right machine
Skip if
- Your machine doesn't have high-flow — you'll get no performance benefit and may damage fittings
- You're doing light grass cutting — standard flow is sufficient and the attachment costs less
Also consider
- Standard rotary cutter if your machine doesn't have high-flow auxiliary
- Brush mulcher/forestry mulcher if you need to process material over 4 inches diameter
Designed for John Deere machines but mounts to any skid steer or CTL with a universal SSQA quick-attach plate.

Care & Maintenance
- Inspect blade tips or flail hammers for wear after each use — dull cutting edges increase engine load and reduce cut quality significantly
- Check all blade bolts for proper torque before every use — loose blades on a high-RPM rotary cutter are a serious safety hazard
- Grease deck spindle bearings after every 8 hours of operation — spindle bearing failure is the most common and expensive rotary cutter repair
- Check the belt drive or hydraulic motor for overheating signs (excessive heat, smell) after extended cutting sessions in dense material
- Remove wrapped material (wire, twine, root) from around the rotor shaft after every use — wrapped material cuts through shaft seals and causes bearing contamination
How to Connect
- Attach rotary cutter frame using Bob-Tach
- Connect hydraulic couplers for motor
- Test blade rotation direction before cutting
- Keep 50m+ clear of bystanders — blade tip speed is extremely high
