About the rotary cutter
A tractor-mounted, vertical-axis grass cutter with rear discharge for grass maintenance in gardens, parks, green areas and orchards. The HM configurations use PTO drive and model-specific working widths.
Features & benefits
Rear discharge
The HM layout releases cut grass behind the deck during operation.
PTO gearbox drive
The gearbox transfers tractor PTO power to the vertical-axis cutting blades.
Typical applications

Rotary cutter questions
How does it differ from a flail mower?
A rotary cutter uses blades rotating on a vertical axis beneath a deck. A flail mower uses multiple flails on a horizontal rotor.
How do I compare the rotary cutter models?

What connection information should I provide?
Send the tractor make and model, hitch category and lifting capacity, plus the actual mounting arrangement.
Does this product require PTO power?
Yes. Check the specified PTO speed, available PTO power and driveline arrangement.
