Our take on the Walker MTGHS Kohler Command CH730 Compatible Engine Replacement Kits

A drop-in replacement engine kit for the Walker MTGHS mower, built around a new Kohler Command CH730 V-twin or a Honda GX630. The Honda version ships as a complete kit with driveline adapters, exhaust, mounting hardware, an electrical harness, a three-year commercial warranty and unlimited technical support. The Kohler version is the closer match to the original engine, so wiring and mounting stay simple, while the Honda brings a two-barrel carburetor and hemispherical combustion chambers for strong torque and easy starting. It suits owners of an aging MTGHS who want to keep the machine running rather than replace it, and who can handle minor wiring work.

About the Walker MTGHS Kohler Command CH730 Compatible Engine Replacement Kits

This is a replacement engine kit for the Walker MTGHS. It comes with a new Kohler Command engine or a new Honda GX630 V-twin, along with the parts needed to install it. The Honda kit includes the engine, driveline adapters, exhaust, mounting accessories and an electrical harness.

The Honda GX630 has a two-barrel inner-vent carburetor for more precise fuel metering. Its fuel economy is similar to fuel injection, with the simplicity of a carburetor. It has a hemispherical combustion chamber, a forged steel crankshaft and pressure-fed crankshaft bearings. A high-capacity pump delivers oil consistently, and a large air intake and a high-efficiency cooling fan handle cooling.

It has a standard 10% governor, an automotive-grade head gasket and hydraulic lifters, so the valve train needs no maintenance. Some minor modifications are still required, and detailed wiring instructions are provided.
