Specs At A Glance

Good To Know

Q: Do I need to replace all spindles at once? A: Replacing the full set together keeps blade heights even and prevents uneven cutting across the deck. It also saves repeat disassembly later.

Q: Are the blades pre-sharpened? A: Blades arrive with a factory edge and are ready to install. Check the edge before each season and sharpen as needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
