SR820
McConnel’s largest and most productive mower, the SR820’s fast cutting action and 8.2m working width enables operators to tackle as much as eight hectares an hour - making it one of the most productive mainstream rotary mowers on the market.
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.
SR820
The SR820 is designed for productivity with five high-performance rotors and a choice of 10 or 30 cutting blades
Overview
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.
