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. Despite its size it is highly manoeuvrable and folds easily to a safe transport width of just 2.8m.
The SR820 is designed for productivity with five high-performance rotors and a choice of 10, 15, 20 or 30 hardened updraft swinging blades that enable it to tackle material up to 50mm thick.
Reliability is enhanced by a six gearbox driveline, each with built-in slip clutch protection, ensuring the power is spread evenly across the cutting width. This feature also enables an even cut and spread and an attractive finish.
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 rotors.
