First Considerations in How To Build A Racing Mower

If you've ever considered how to build a racing mower, then this is your lucky day.

We'll start with the engine. But first, you have to decide in which division you'll be racing. Once you've determined the division, download the rulebook and make sure that your intended engine modifications comply with all the rules.

It is advisable to take your modifications to the limit. This ensures you get the most out of your engine. Note that I said take it to the limit, not over the limit. This is an important distinction when learning how to build a racing mower.

I’ve never heard a mower racing driver say that his mower has too much horsepower. More often than not, drivers say they need more horsepower. This is one reason why you need to take your modifications to the limit…just to keep up with your competition.

If you don’t know anything about engines, you can always find engine rebuilding and repair shops in your area. They will be thrilled to help you out and put as much horsepower in your engine.

The key components that you have to concentrate on when learning how to build a racing mower are: carburetors, flywheels, valves, pistons, heads, and crankshafts. You’ll be ready for any mower racing event once you’ve addressed each of these components.

Carburetors play a big role in your engine’s combustion process but they can be very limiting if not modified properly. You will have to spend time porting and polishing its components in order to achieve the desired results. But for those who have extra money, you can always take a short cut by purchasing racing carburetors from your local shop.

Stock flywheels are weak and are not safe for racing; this is something that you have to be familiar with when learning how to build a racing mower.

To make your mower fit for the tracks, you will have to purchase a high-quality billet flywheel, like those from ARC, and make sure that you choose the lightest one. Light flywheels allow the engine to rapidly build up the much needed RPM when passing competitors during mower racing events.

As for your valves, you will need to prepare them by doing a precision multi-angle valve job.

Engine heads may also become a limiting factor to the overall performance of your engine. To address this issue, simply port and polish the intake for improved airflow.

Crankshafts, on the other hand, are heavy and will affect your mower’s ability to accelerate. To make up for this, you need to find a way to reduce its weight while keeping it is balanced for that added durability.

These are the most important things that you have to be aware of when learning how to build a racing mower. If you take all of this into account and push the envelope of the modification allowances, you’ll be ready to focus on your driving skills for the next mower racing event.
