04331700 09089700 Starter Ignition Switch 04331600 Compatible with Ariens Gravely Max Zoom XL ZT Apex Ce 48 52 60 Zero Turn Mower Lawn Tractor Starter Ignition Switch with 2 Key 6 Terminals

What It Is

This is a 6-terminal starter ignition switch assembly (replaces OEM part numbers 04331700, 09089700, 04331600) designed for zero-turn mowers and lawn tractors. It controls power to the starter, ignition, and accessories, and includes two keys.

Fitment & Compatibility

Before buying, check these specifics:

• OEM replacements: Fits Ariens and Gravely models including Max Zoom XL, ZT, Apex, and CE series in 48", 52", and 60" deck sizes. Also compatible with some Husqvarna and Craftsman models using the same terminal layout.
• Terminal count: This switch has 6 blade terminals (labeled B, S, A1, A2, I, M). Verify your original switch has 6 terminals in the same positions—some models use 5 or 7 terminals.
• Physical size: Measure the mounting hole diameter (typically ~1.375") and shaft length. This switch has a standard 3/4" shaft and fits most panels up to 1/4" thick.
• Key profile: Keys are unique to this switch—not interchangeable with OEM keys. Ensure the key slot matches your existing switch.
• Voltage rating: Designed for 12V systems only—not for 24V or 6V mowers.

Key Things to Know

• Quality concerns: At $17.99, this is an aftermarket budget switch. Some users report plastic housing feels less durable than OEM, and key insertion can be stiff initially.
• Installation difficulty: Easy—swap takes 10-15 minutes with basic tools (socket wrench, screwdriver). Disconnect battery first. Label wires before removal to avoid confusion.
• Common gotcha: Terminal positions may not match OEM exactly. If your mower has a safety interlock circuit (e.g., seat switch), double-check wiring diagrams—miswiring can prevent starting or disable safety features.
• No instructions included: You’ll need to match wire colors or use a multimeter to identify terminal functions (B = battery, S = starter, etc.). Take a photo of the old switch wiring before removing.

Should You Buy It

Buy this if you need a quick, low-cost replacement for a worn-out ignition switch on an Ariens or Gravely zero-turn mower and are comfortable matching wires yourself. Skip it if you want OEM durability, prefer plug-and-play installation with instructions, or need a switch with a metal housing for heavy use. For the price, it’s a functional stopgap but not a long-term upgrade.
