GREENKEEPING
Why Cylinder Mowers Are Vulnerable
Cylinder mowers are designed for precision and high presentation standards. Their close cutting tolerances and roller configurations deliver exceptional finish— but they are not designed to operate in persistently contaminated conditions.
Soft casts passing under rollers are compressed and smeared causing build up on rollers which in turn alters the height of cut. Soil entering the cutting interface accelerates dulling. As tolerances open up, quality of cut suffers.
This is not a criticism of cylinder technology— it is simply a recognition that their strengths become vulnerabilities in heavy casting conditions.
For many facilities, this has prompted a review of mowing strategy during peak worm activity.
A Practical Alternative: Trailed Rotary Mowers
One increasingly adopted approach is the use of modern trailed rotary mowers for affected areas.
Today’ s rotary designs differ significantly from older perceptions of rotary cutting. Key features typically include:
• Large-diameter smooth rollers
• Scraper systems to prevent roller build-up
• High blade tip speeds
• Strong airflow through the deck
The blade speed and airflow help disperse material while maintaining an even cut. Because the cutting system does not rely on a tight scissor action, soil contamination does not create the same abrasive grinding effect experienced with cylinders.
For many grounds teams, this means:
• Less impact on sharpening schedules
• Fewer workshop interruptions during casting season
• Improved operational efficiency
It is not about replacing cylinders entirely— but about deploying the right equipment for the conditions.
Where Rotary Makes Sense
Trailed rotary mowers are not intended for ultra-low height-of-cut environments such as fine greens. However, they are particularly well suited to:
• Roughs and Fairways
• Sports outfields
• Amenity turf
• Large maintained areas
• Sites experiencing prolonged casting seasons
For facilities prioritising durability, efficiency and consistent presentation during challenging months, a rotary can provide a practical and cost-effective solution.
For example, many Trimax Snake users lower the height of cut and use the machine as their primary fairway mower during peak worm activity. This allows them to protect dedicated fairway cylinder mowers from abrasive wear during the winter months, while still maintaining consistent turf presentation.
Rethinking Worm Cast Management
With chemical control no longer an option, worm cast management is fundamentally a machinery decision.
If you are experiencing:
• Increasing sharpening frequency
• More workshop downtime in autumn and winter
• Labour diverted to brushing and remedial work
• Inconsistent presentation in damp conditions
It may be time to review whether your current mowing approach is working with— or against— today’ s environmental reality.
Earthworms will remain a vital part of healthy soils. The challenge is ensuring their activity does not undermine surface quality or operational efficiency.
