Replacing Your Engine On A Scott Bonnar Reel Mower

Replacing Your Engine On A Scott Bonnar Reel Mower

The Scott Bonnar Reel Mower range, is still considered one the best mowers for a low, clean and high quality cut. You can definitely identify a lawn that has been cut with a Scott Bonnar Reel Mower.

One of the most common questions we get, is what engine would be a suitable replacement option for the 430 and 450 series models. 

The new Briggs & Stratton 3.5 Horsepower 550 Series Horizontal Shaft Engine, would be the most suitable replacement, as it has the same shaft and mountings to bolt straight on.

The Briggs & Stratton powerful 550 Series petrol engine utilizes (OHV) overhead valve design technology. It features an automotive style air filter, cast iron cylinder sleeve, and dual bearings for longer life. 

Briggs & Stratton's great reputation for easy starting and superb reliability, make the 550 Series the ideal replacement engine for your Scott Bonnar Reel Mower.

Mike Donovan,

You have a choice of a 5/8" or 3/4" diameter shaft when replacing the engine on your Scott Bonnar mower, you will need to measure the diameter of shaft of the engine you are replacing so everything fits back together easily.
