Our take on the Walker MTGHS Kohler Command CH680 Compatible Engine Replacement Kits

A drop-in replacement engine kit for the Walker MTGHS mower, built around a new Kohler Command CH740 V-twin. The kit adds an electrical harness pigtail, a kit guarantee and unlimited technical support, and the wiring needs minor modification with detailed instructions supplied. It suits owners of a tired MTGHS who want to keep the machine rather than replace it. Against a bare engine swap, the kit covers the wiring and support side; the Honda GX630 version adds driveline adapters, exhaust and mounting parts that the Kohler kit does not include.

About the Walker MTGHS Kohler Command CH680 Compatible Engine Replacement Kits

This is an engine replacement kit for the Walker MTGHS. It is offered with a new Honda GX630 V-twin engine or a new Kohler Command CH740 engine. The kit includes what is needed to convert the machine from the old engine to the new one, unless otherwise stated.

The Honda GX630 has a two-barrel inner-vent carburetor for more precise fuel metering. Its fuel economy is similar to fuel injection. 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 high-efficiency cooling fan help with cooling.

The Kohler CH740 starts in all weather conditions, from 0 to 110 degrees. It has a standard 10% governor and an automotive-grade head gasket. Hydraulic lifters mean no valve train maintenance. The Kohler kit includes a wiring harness pigtail that simplifies the wiring, though some minor modifications are required. Detailed wiring instructions are provided.
