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.
