Bill's Place Toro Part # 145-5819 Grass Bag

What It Is

This is the OEM replacement grass bag for select Toro walk-behind mowers, specifically the 145-5819 part. It collects clippings during mulching or bagging operations, designed for residential mowing on standard lawns.

Fitment & Compatibility

Before buying, confirm your mower model. This bag fits Toro models with a 21-inch or 22-inch steel deck (e.g., Super Recycler, Recycler, and Personal Pace series from the 2000s-2010s). Check your mower’s model number (stamped on the deck or under the rear flap) against Toro’s parts list for 145-5819. It will not fit 19-inch or 30-inch decks, or any non-Toro brand. Measure the bag opening: it should match your mower’s rear discharge chute (approx. 6.5” x 8”). OEM only—no aftermarket cross-references exist for this part.

Key Things to Buy

• Quality: OEM Toro fabric is durable and resists tearing, but the plastic frame/metal hooks can crack if overstuffed or left in sun. Expect 2-3 seasons with moderate use.
• Installation: Simple—remove the old bag, slide the hooks into the mower’s rear bracket, and snap the top lip under the discharge cover. No tools needed.
• Common gotchas: The bag may sag if not fully seated; check that the flap seals against the deck to avoid clippings spilling. If your mower has a side-discharge kit, remove it first—this bag is bag-only.
• Fit note: Some 2015+ Toro models use a different bag design (e.g., 145-5992). Double-check year and series.

Should You Buy It

If you own a compatible Toro mower and your original bag is worn, torn, or missing the frame, this is the correct replacement. It’s a straightforward, drop-in fix that restores full bagging performance. Skip it if you have a non-Toro mower or a newer Toro model—you’ll need a different part number.
