What engine is in this kit?

It is the Kohler Command CH740, a 25 hp air-cooled V-twin with 725cc displacement and a horizontal shaft. It uses full-pressure lubrication with an oil pump.

Which mowers does it fit?

It is a replacement kit for the Walker MT application, so it is meant for Walker MT-series machines rather than other brands. Check your model and engine before ordering.

Is it more powerful than the engine it replaces?

No. It is a like-for-like replacement at 25 hp, so expect the same performance rather than an upgrade.

Can I install it myself?

It is a full engine swap, so it needs mechanical skill, the right tools and time. Many owners have a dealer or small-engine shop do the work.

What maintenance does the CH740 need?

It is air-cooled, so keep the cooling fins and air filter clean, change the oil on schedule and check the oil level often. There is no coolant to service.
