SR620

McConnel’s high-performance SR620 features a 6.2m cutting width, five powerful rotors and a choice of 10 or 30 hardened updraft swinging blades for outstanding productivity.

Ideal for large-scale farmers, local government teams, and professional mowing contractors, SR series machines can be used in a huge variety of applications from airports and sports venues to pasture and stubble.

Overview

Capable of tackling everything from grass to gorse, the SR620 can cut material up to 50mm thick, and has a fast-cutting action which enables operators to tackle up to six hectares an hour. Flexible wings with 115 degrees of movement ensure the SR620 closely follows the contours of the ground and delivers an attractive cut with an even spread, while walking axles deliver a smoother ride.
