What It Is

This is a replacement discharge deflector chute (OEM part 137-7046) for Toro Timecutter and Exmark Quest E-Series zero-turn mowers with a 42-inch deck. It directs grass clippings downward during side discharge and includes all mounting hardware.

Fitment & Compatibility

• Exact models: Toro Timecutter SW4200, ZS4200S, 75742, 74665, 75748, 75749, 74667, 74677, 74705, 74711, 75742TA, 75742W; Exmark Quest E-Series 42" (check your serial number prefix).
• Deck size: Only fits 42-inch cutting decks. Do not use on 50" or 54" decks.
• OEM vs aftermarket: This is a genuine Toro/Exmark part, not a generic. Expect exact fit but higher price than third-party options.
• What to measure: Ensure the two mounting holes on your deck are 6.5 inches center-to-center and the chute pivot pin diameter is 0.25 inches. If your old chute broke at the hinge pin, verify the pin hole isn’t wallowed out.

Key Things to Know

• Installation difficulty: Easy—one bolt, one pin, and a spring. No special tools needed. Takes 10 minutes.
• Spring tension: The included spring is pre-stretched; you may need pliers to hook it onto the deck bracket. If the spring is too tight, the chute won’t drop fully.
• Common gotcha: The chute may not stay down if the deck’s pivot pin hole is worn. Replace the pin (Toro part 1-633690) if it’s loose.
• Durability: Molded plastic—can crack if you hit a tree root or curb. Keep a spare if you mow rough terrain.

Should You Buy It

Buy this if your OEM chute is cracked, missing, or won’t stay in place. It’s the correct fit for the listed 42" Toro/Exmark models and comes with all hardware. Skip it if you have a different deck size or want a universal chute that might need modification—stick with OEM for hassle-free replacement.
