Agri-Fab Part 46780 21-3/4-Inch Brush

What It Is

The Agri-Fab Part 46780 is a 21-3/4-inch brush replacement for lawn sweepers. It’s designed to attach to the sweeper’s reel to collect grass clippings, leaves, and light debris—not for use on mower decks or as a standalone tool.

Fitment & Compatibility

This brush fits Agri-Fab lawn sweepers with a 21-3/4-inch brush length. Check your sweeper’s model number: it’s compatible with many Agri-Fab sweepers (e.g., 46-0290, 46-0300, 46-0320) but not all. Measure your existing brush’s overall length (including end caps) before ordering—this one is exactly 21-3/4 inches. It replaces OEM part number 46780. Not compatible with sweeper brands like Brinly, John Deere, or Craftsman unless they use the same Agri-Fab reel design. Verify your sweeper’s brush diameter (typically 6-7 inches) to ensure it fits the reel housing.

Key Things to Know

• Quality: Bristles are stiff polypropylene—good for leaves and grass, but not for heavy twigs or wet, matted debris. Expect 2-3 seasons of moderate use before bristles wear.
• Installation: Moderate difficulty. Requires removing the sweeper’s reel end caps and sliding the old brush off. You may need a mallet to tap the new brush into place. No special tools, but patience helps.
• Common gotcha: The brush is sold without end caps or bearings—reuse your old ones if they’re in good shape. If caps are cracked, order them separately (Agri-Fab part 46781).
• Fitment nuance: Some newer Agri-Fab sweepers use a slightly different reel design—check that your sweeper’s brush shaft is the same diameter (usually 5/8-inch) before buying.

Should You Buy It

Buy it if your Agri-Fab sweeper’s brush is worn out and you want a direct, affordable OEM replacement. Skip it if you need a brush for a different brand or a sweeper with a non-standard reel—you’ll waste time on fitment. For heavy-duty use (e.g., commercial landscaping), consider a stiffer aftermarket brush instead.
