Mow away from your viewpoint
Grass bent away from you reflects more sunlight and appears lighter.
Don't see your mower listed? Call us—we can fit the CheckMate™ to most mowers on the market.
A CheckMate™ roller gently bends the grass as you mow. Alternating directions change how sunlight reflects from the blades, creating the light and dark stripes you see.

The roller does not paint or permanently mark the lawn. It creates contrast by changing the direction the grass lays—and therefore the way it reflects light.
Grass bent away from you reflects more sunlight and appears lighter.
Grass bent toward you creates more shadow and appears darker.
Those light and dark passes build the finished stripe pattern across the lawn.

The CheckMate™ system follows the contours of the lawn while its solid-rubber rollers provide consistent pressure—without water, sand, or routine filling.
On riding mowers, an oversized roller can overlap adjacent passes, catch landscaping, and reduce maneuverability. The mower’s rear tires contribute to the stripe, so the properly sized roller connects those tire tracks into one clean result.
Our product pages do the sizing for you. Choose your mower and deck size, and the page presents the recommended CheckMate™.

Cool-season grasses generally grow more upright and hold the roller’s direction especially well. Warm-season grasses tend to spread or crawl, so their stripes are often subtler.
Kentucky bluegrass, fescue, and ryegrass.
Zoysia, centipede, Bermuda, and St. Augustine.
Once you understand alternating passes, use the same light-reflection principle to build checkerboards, diamonds, and waves.
