John Deere OEM Lower Bagger Chute 102 115 125 135 L 110 LT 133 155 166 170 D 110 LA 100 X 300 310 Z 225 AM143911

What It Is

This is the OEM lower bagger chute—the rigid plastic duct that connects your mower deck’s discharge opening to the upper bagger chute or bagger assembly. It directs grass clippings from the deck into the collection system. Designed for John Deere 100, X300, and select older 100-series lawn tractors, it’s a direct replacement for worn, cracked, or missing chutes.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This chute (AM143911) fits:

• Lawn tractors: 102, 115, 125, 135, L 110, LT 133, 155, 166, 170, D 110, LA 100
• X-series: X300, X310
• Z-series: Z225

Critical checks:

• Deck size: Works with 38", 42", and 48" decks—but not all models use the same chute. Verify your deck’s discharge opening shape.
• Bagger system: Compatible only with John Deere bagger kits that use a two-chute design (lower + upper chute). Not for single-chute or side-discharge setups.
• OEM vs aftermarket: This is genuine John Deere. Aftermarket versions may fit but often have thinner plastic and looser seals. If you have a tight fitment, stick with OEM.
• Measurements: Chute length is roughly 12 inches, width about 6 inches at the deck opening. Compare to your old part.

Pro tip: Remove your old chute and compare the mounting tabs and flange shape. If your model isn’t listed, measure the deck discharge and chute mounting holes.

Key Things to Know

• Quality: OEM plastic is thicker and UV-resistant. Aftermarket chutes often crack within one season.
• Installation difficulty: Easy—two bolts or pins, no tools needed. But the chute must snap firmly onto the deck lip. If it doesn’t, clippings will leak.
• Common gotcha: The chute can warp in direct sun. Store the mower in shade or a garage to extend life.
• Compatibility gotcha: Some models (like certain X300s) may need a different upper chute or adapter if you’re replacing only the lower. Check your bagger kit part number.

Should You Buy It

Buy this if your original lower chute is cracked, missing, or leaking clippings, and you want a perfect fit without modifications. It’s the right choice for John Deere owners who value durability and hassle-free installation. Skip it if you’re on a tight budget and can tolerate an aftermarket chute with possible fit issues.
