Walker A10 DT40A 40″ Dethatcher Attachment

The Walker A10 DT40A Dethatcher is a productive, front-mounted solution designed to efficiently remove lawn thatch while mowing in a single pass. When paired with Walker’s Grass Handling System on Models S, C, T, and D, the dethatcher lifts and loosens debris, allowing it to be collected simultaneously—saving time and eliminating extra cleanup steps.

Originally developed by Walker in 1989, this attachment has evolved with upgraded durability and improved ease of use. The addition of front gauge wheels ensures consistent tine depth across uneven or articulating terrain, while structural improvements such as a reinforced tine tray spar, redesigned transport latch, and folding handle enhance long-term reliability.

 The Walker A10 DT40A 40″ Dethatcher Attachment is available at Kooy Brothers Equipment Ltd. located at 1919 Wilson Avenue in Toronto, Ontario.
