Generic Kohler 7000-Series Starter — Compatible with KT/SV Engines, 9-Tooth 12V 250A Aluminium Base

Replacement 12V starter for Kohler 7000-series mowers that delivers reliable cranking with upgraded steel gears and an aluminum base for longer life.

This starter is built to fit a wide range of Kohler engines (KT and SV/Courage families) and many popular Cub Cadet models, providing a direct, high-torque swap for worn or failed stock starters. It combines a 250A electric current rating, 800W power output and a 9-tooth drive gear to give stronger bending radius and improved torque where it matters most. The housing uses aluminum alloy for corrosion resistance while upgraded carbon steel gears increase durability under heavy load.

Which engines and mower models will this starter work with?

This unit is compatible with Kohler KT and SV/Courage engine codes and lists numerous Cub Cadet model families. Always cross-check part numbers or engine code on your mower before ordering to confirm fitment.

• Fits Kohler: KT715, KT725, KT730, KT735, KT740, KT745 and SV710–SV840 series
• Works on Kohler Courage 20–27 HP engines referenced in compatibility lists
• Also compatible with many Cub Cadet models including LGT, GTX, LT, LTX, RZT, XT and Z-series
• Reference OEM numbers like 3209801, 3209803, 3209804, 3209808 when verifying

How does the 9-tooth gear design affect starter performance?

The 9-tooth gear used in this starter increases the bending radius at teeth roots, which improves torque transmission and reduces stress at the joint. That design choice helps the motor crank more effectively, especially on cold starts or higher-compression engines.

• 9-tooth gear provides larger bending radius than 10-tooth alternatives
• Improved torque at the gear joint for consistent engine engagement
• Carbon steel gear construction increases wear resistance under load

What materials and build upgrades extend the starter's lifespan?

This starter pairs carbon steel gearing with an aluminum-alloy base to reduce corrosion and add stiffness without excessive weight. Those material upgrades reduce wear and help the starter resist the environmental stresses typical of lawn and garden equipment.

• Carbon steel gears for higher hardness and reduced tooth wear
• Aluminum-alloy housing lowers weight and resists oxidation
• Enhanced anti-corrosion properties for longer service life

What electrical specifications should I expect and how does that impact installation?

The starter runs at 12 volts with a 250A current rating and delivers about 800W of power, offering strong cranking capability for small engines. Installation follows the same mounting points and electrical connections as the original starter for compatible engines, but verify wiring polarity and bolt pattern before fitting.

• 12V system, 250A current rating, ~800W power output
• Torque approximately 2.5 Nm and 9-tooth pinion gear
• Designed for direct replacement using original mounting and electrical connections

Who is this for: This starter is aimed at homeowners, landscapers and small-engine repair shops who need a dependable replacement for Kohler 7000-series and compatible Cub Cadet mowers. If your mower shows hard starting, slow cranking, or an intermittent starter problem and the engine model or OEM numbers match those listed, this unit offers a durable, cost-effective swap backed by upgraded materials and a one-year warranty.
