L110 Carburetor for John Deere LT155 L110 LT160 Lawn Mower with 15hp 17.5hp Kohler SV600 SV540 SV530 SV590 Command PRO Engine

What It Is

This is an aftermarket carburetor designed to replace the fuel system component on John Deere LT155, L110, and LT160 lawn tractors equipped with Kohler Command PRO engines. It handles the air-fuel mixture for engines in the 15hp to 17.5hp range.

Fitment & Compatibility

Before buying, verify your engine model—this carb fits Kohler SV600, SV540, SV530, and SV590 engines. It does not fit Kawasaki or Briggs & Stratton engines. Check your mower’s engine shroud for the model number (e.g., SV540-1234). This unit is a direct replacement for OEM part numbers like Kohler 12 132 14-S, 25 132 14-S, or 24 132 14-S. Deck size (38", 42", 48") doesn’t matter—only engine model matters. Measure your carb’s mounting bolt spacing (typically 2.5" center-to-center) and intake flange size (1.25" diameter) to confirm.

Key Things to Know

• Quality variance: This is a budget aftermarket carb. Some units may have slightly rough castings or float adjustments out of spec—check the float level (should be parallel to bowl gasket) before installing.
• Installation difficulty: Moderate. Expect to replace the gasket (included) and possibly adjust the idle mixture screw (usually 1.5 turns out from lightly seated). You’ll need to drain old fuel and clean the fuel line.
• Common gotcha: The included fuel line may be too short or wrong diameter for your mower—reuse your original line or buy a separate 1/4" fuel line. Also, the choke linkage may need bending to align properly.
• Tuning required: After install, you’ll likely need to adjust idle speed and mixture. A tachometer helps, but you can set it by ear—aim for smooth idle without surging.

Should You Buy It

If your Kohler-equipped John Deere has a clogged or failing carb and you’re comfortable with basic DIY tuning, this is a cost-effective fix. It’s not for purists needing OEM durability or for engines with severe wear—but for a quick, functional replacement at a fraction of dealer cost, it gets the job done.
