Now that the fall golf season has arrived and temperatures are starting to drop, putting greens require more-delicate care to remain in optimal condition. One often-overlooked adjustment is the transition from grooved front rollers to smooth rollers on greens mowers. While grooved rollers are highly effective during the growing season, their design can impose stress on turf as it enters dormancy or experiences periods of slower growth. Making this switch in the fall can provide several benefits for maintaining healthy greens, including:

Reduced wear and tear. A grooved roller exerts more pressure on the putting surface, creating additional stress on the turf. During fall and early winter, the grass is more vulnerable due to slower growth and can’t recover from damage as quickly as it can in the growing season. A smooth roller is gentler and lowers the risk of damage to semi-dormant or slowly growing grass by reducing the mechanical stress placed on the turf, leading to less wear and tear over time.

Preventing scalping. Grass in the fall and winter seasons tends to be shorter and less dense. This means a grooved roller can increase the likelihood of scalping, especially on undulating greens. A smooth roller minimizes this risk by distributing the mower's weight more evenly.

Improved surface quality. A smooth roller can help produce a more even cut, resulting in a better putting surface with fewer imperfections. The lack of grooves also ensures fewer marks are left on the greens.

In conclusion, switching to a smooth front roller on greens mowers during the fall and winter season offers several key benefits and helps protect the turf during its most vulnerable period. As turfgrass growth slows, this gentler approach to mowing promotes healthier greens, better playability and quicker recovery come spring. This simple change will help you maintain high-quality putting surfaces throughout the cooler months.
