This pull-type PTO-driven gang finish mower is designed for tractors in the 35–80 HP range and provides wide-area cutting performance from 12 to 20 feet. It is built for large-scale turf maintenance including parks, sports fields, estates, agricultural land, and commercial properties. Operating at 540 RPM with a constant velocity driveline, it delivers consistent cutting performance while maintaining maneuverability around obstacles and terrain variations.

The mower features multiple independent floating decks that adjust to ground contours individually. This allows the cutting system to maintain an even finish across uneven terrain, including slopes, swales, and irregular ground surfaces. Each deck operates independently, helping maintain consistent cutting height and reducing striping or missed areas during operation.

A heavy-duty gearbox system with spiral gearing and SKF bearings supports efficient power transfer and extended service life. The belt-driven system uses reinforced belts with a manual tensioning mechanism to maintain consistent tension and reduce long-term wear. Cast iron pulleys support balanced operation and improved durability under continuous use.

The telescoping wing system allows adjustment of cutting overlap to match field conditions, improving both efficiency and cut quality. Hydraulic folding wings provide fast transport configuration and compact storage. Safety systems include chain shielding and driveline protection to reduce operational risk.

This mower is available in multiple configurations to match tractor horsepower and acreage requirements, providing flexibility for different professional mowing applications.
