The mower deck is made of steel and allows for mulching or rear bagging of clippings. The height can be adjusted using the wheel adjusters on each wheel. The handle's height can also be adjusted. To operate the mower, the throttle control needs to be moved to the FAST position. The engine is primed three times if it's cold, and then the starter rope is pulled quickly.
