FAQ

How do I confirm this pulley fits my mower?

Start by matching the OEM pulley number on your original part. Then compare the outside diameter, bore or center-hole size, pulley width, belt profile, deck layout, and mower model.

Can I order by appearance alone?

No. Similar-looking deck pulleys can have different bore sizes, offsets, belt profiles, and deck applications. Match the part number and dimensions first.

What causes a mower deck pulley to fail?

Common causes include worn bearings, belt misalignment, impact damage, seized hardware, or long-term wear from deck belt tension.
