In the world of rough grass machinery, rotary field mowers are the best all-rounders and are capable of maintaining large open areas of grass. Some models of rotary field mower are also able to clear rough scrub and mature undergrowth with relative ease. A heavy duty metal blade housed beneath a sturdy steel cutting deck is the normal design of rotary field mowers, with at least one forward gear to aid travel over uneven ground. Often favoured by professional landscapers and those needing to clear areas out of the reach of heavy agricultural machinery, their comparatively small size and low weight makes them exceptionally manoeuvrable on difficult terrain. Owners of large properties will find rotary field mowers invaluable for keeping pastures and areas of parkland properly maintained throughout the growing season.
