SR420
Overview
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.
McConnel’s range of high-performance delta wing rotary mowers has been designed to deliver peak performance over the ground with working widths from 4.2 to 8.2m, flexible wings, and powerful triple rotors.
Hardened updraft swinging blades ensure an effective cutting capacity of up to 50mm, while hydraulically folding wings enable a fast and smooth transition from transport to working position.
