Agri-Fab Qty 4 Craftsman 21" brush for 42" Tow Behind Lawn & Leaf Sweeper 46780

What It Is

This is a set of four replacement brushes for the Craftsman 42-inch tow-behind lawn and leaf sweeper (model 46780). They sweep grass clippings, leaves, and light debris into the hopper as you pull the sweeper behind a lawn tractor or zero-turn mower.

Fitment & Compatibility

• Exact use: Designed for the Craftsman 42" tow-behind sweeper (model 46780). Not for other sweepers without verifying dimensions.
• Measurement check: Each brush is 21" long. Measure your existing brush length to confirm—if yours are shorter or longer, these won’t fit.
• Mounting: They slide into the sweeper’s brush bar and are secured with a pin or bolt. Make sure your sweeper uses the same retaining method (most 46780 units do).
• OEM vs aftermarket: These are genuine Craftsman/Agri-Fab parts, so fitment is guaranteed for that model. Aftermarket alternatives may be cheaper but often differ in bristle stiffness or length.

Key Things to Know

• Quality: Bristles are stiff but flexible—good for leaves and dry grass, but may wear faster on wet, heavy debris or gravel surfaces.
• Installation: Easy. Remove the old brushes by pulling the retaining pins, slide the new ones in, and re-pin. No tools required.
• Common gotcha: If your sweeper hasn’t been used in a while, the brush bar may be rusted or sticky. Lubricate the bar pins before inserting new brushes to avoid binding.
• Wear indicator: Replace when bristles are less than 1/2" from the brush base—performance drops sharply past that point.

Should You Buy It

If you own a Craftsman 42" model 46780 sweeper and your brushes are worn down, this is the direct, no-guesswork replacement. It’s a solid value for the price, with easy installation and proven durability for typical lawn cleanup. Not for other brands or sizes—double-check your model number first.
