Types of ATCO Lawn Mower Belts
Most ATCO ride-on mowers and lawn tractors use multiple belts. Each belt performs a different function and should always be replaced with the correct specification.
ATCO Drive Belts
The drive belt transfers engine power to the transmission, allowing the mower to move forwards and backwards. If your ATCO mower loses drive or struggles under load, inspect the drive belt for wear.

ATCO Deck Belts
The deck belt powers the cutting blades. A worn or stretched deck belt can reduce cutting performance, cause uneven mowing and prevent the blades from engaging correctly.

ATCO PTO Belts
Many ATCO lawn tractors use a PTO belt to engage the cutting deck. Using the correct replacement ensures reliable blade engagement and long service life.
