131-3945 Deck Mount Rod Compatible with Toro Quest E S Series & TimeCutter SWX 4250, ZS 3200S, 4200S, 4200T, 5000, Replaces 104-8047

What It Is

The 131-3945 Deck Mount Rod is a steel pivot pin that secures the mower deck to the frame on select Toro zero-turn and lawn tractors. It replaces OEM part 104-8047 and is used to attach the deck lift linkage or deck hanger, critical for deck height adjustment and stability during operation.

Fitment & Compatibility

Before buying, verify your mower’s model and series. This rod is designed for Toro Quest E and S Series (e.g., Quest 42" deck models), plus TimeCutter SWX 4250, ZS 3200S, 4200S, 4200T, and 5000 models. It will not fit TimeCutter SS, MX, or other series without cross-checking.

Check the rod’s overall length (approx. 3.5") and diameter (0.5") against your original part. If your mower’s deck mount uses a cotter pin or hairpin clip, ensure the rod’s holes align with your existing hardware. This is an aftermarket replacement; OEM Toro part 104-8047 is identical in function but may vary slightly in finish.

Key Things to Know

• Quality & Durability: Zinc-plated steel resists rust, but inspect for burrs or rough edges before installation—these can cause premature wear on bushings.
• Installation Difficulty: Easy—slide out old rod, slide in new one, secure with cotter pin or clip. No tools required beyond pliers or a punch for stubborn pins.
• Common Gotcha: If your old rod is seized, penetrating oil and a hammer may be needed. Don’t force it; you can damage the deck bracket.
• Fitment Check: Always measure your old rod’s length and diameter. Some early Quest models used a slightly different rod (104-8048) that is not interchangeable.

Should You Buy It

If your Toro Quest or TimeCutter SWX/ZS deck mount rod is bent, worn, or missing, this $7 part is a direct, affordable fix. It’s ideal for DIY owners who want to restore proper deck alignment without buying OEM. Avoid it if your mower is not listed—measure first to confirm.
