Bonbo 4PCS 46780 21-3/4-Inch Brush Compatible with Craftsman Agri-Fab 42" Tow Behind Lawn & Leaf Sweeper, Replace for 45-0261, 45-0456, 45-0492, 45-0521

What It Is

The Bonbo 4PCS 46780 brush set is an aftermarket replacement for the brush assembly on Craftsman and Agri-Fab 42-inch tow-behind lawn and leaf sweepers. These brushes sweep leaves and debris into the hopper as you tow the sweeper behind a lawn tractor or zero-turn mower.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This set is designed for 42-inch tow-behind sweepers only. Do not use on 30" or 50" models.
• Model numbers: Directly replaces OEM parts 45-0261, 45-0456, 45-0492, and 45-0521. Fits Craftsman 46780 and Agri-Fab 45- series sweepers.
• Measurements: Each brush is 21-3/4 inches long with a 1-1/2 inch diameter mounting hole. Measure your old brush length and hole size to confirm. If your sweeper uses a different hole diameter (e.g., 1-1/4"), these won’t fit.

Key Things to Know

• Installation difficulty: Easy – 15 minutes. Remove the old brushes by sliding them off the mounting rod, then slide the new ones on and secure with the original hardware. No tools beyond a wrench or socket for the rod nut.
• Quality note: These are aftermarket, not OEM. Some users report slightly thinner bristles than original Craftsman brushes, but they still perform well for leaf pickup on dry grass and light debris.
• Common gotcha: The brushes are packed tightly in the box – let them sit in a warm room for an hour to relax before installing, or they may feel stiff and not sweep evenly at first.
• Pack size: You get 4 brushes, which is the full set for a 42" sweeper. No need to buy additional parts.

Should You Buy It

Yes, if you need a budget-friendly replacement for worn brushes on a 42" Craftsman or Agri-Fab tow-behind sweeper and are comfortable with aftermarket quality. Skip it if you need OEM exactness or sweep heavy, wet debris regularly – the bristles may wear faster than originals. For light to moderate leaf cleanup, this is a solid value at $27.
