This is a replacement engine kit for the Walker MTGHS zero turn mower. It is offered with a new Kohler Command CH740 engine or a new V-twin Honda GX630 engine, plus the parts needed to install it.
The Honda kit includes the engine with a 3-year commercial warranty, driveline adapters, exhaust, mounting accessories and an electrical harness. The Kohler kit includes a wiring harness pigtail that simplifies the wiring, though some minor modifications are required. Detailed wiring instructions are provided.
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. The Kohler CH740 has an automotive-grade head gasket and hydraulic lifters, so the valve train needs no maintenance. It starts in temperatures from 0 to 110 degrees and has a standard 10% governor.
