Caltric Upper Chute Compatible with John Deere D125 D310 D140 D150 D155 D160 D170 E100 E110 E120

What It Is

The Caltric Upper Chute is an aftermarket replacement part that directs grass clippings from the mower deck toward the discharge opening. It fits select John Deere lawn tractors with 42-inch or 48-inch decks, primarily from the D100 and E100 series.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size. This chute fits John Deere D125, D310, D140, D150, D155, D160, D170, E100, E110, and E120 models—but only those with a 42-inch or 48-inch stamped deck. Check your deck’s underside for a model tag or measure the cutting width. The Caltric part replaces OEM number GY21148, GY20570, or GY20996, but it’s not a direct OEM part; minor drilling or trimming may be needed on some decks. Also confirm your chute mounting hardware matches: the chute uses two bolts and a spring (not included). If your mower has a different deck design (e.g., fabricated or 54-inch), this won’t fit.

Key Things to Know

• Quality: Caltric parts are budget-friendly but may have thinner plastic than OEM. They hold up for typical residential use but can crack under heavy or frequent use.
• Installation: Moderate difficulty. You’ll need to remove the old chute and spring, then bolt the new one on. Expect to drill or file mounting holes if alignment is off—common on aftermarket parts.
• Common Gotcha: The spring tension must be correct to keep the chute in place during operation. If it’s too loose, the chute can rattle or fall off; too tight, it may bind. Use the original spring if it’s in good shape.
• No Hardware Included: You’ll need your own bolts, nuts, and spring. Check your old setup before starting.

Should You Buy It

If you need a functional replacement for a worn or cracked upper chute on a John Deere D100/E100 series mower and want to save money over OEM, this Caltric chute is a solid choice. It’s best for residential homeowners who mow a standard lawn and are comfortable with minor DIY adjustments. If you need a perfect fit with no fuss or have a commercial-grade mower, stick with the OEM part.
