To clean it first start with a cool engine. If your mower has a fuel valve switch it off. If you can disconnect the spark plug too. Next use a leaf blower to blast away any old dirt and major debris. Now gently lay the mower on its side fuel cap facing up. Try to get rid of any junk on the mowers underside as well.
The 190 cc engine allows you to mow at a decent clip and it starts more easily and runs more efficiently than most side-valve engines. Also the rear-wheel drive makes it so you can mow inclines and hills effortlessly. There are more features than we have space to cover here but we would be remiss if we didnt touch on the Versamow system. This system allows you to choose how much grass is mulched and how much is bagged depending on your yards conditions. It also lets you shred leaves so you no longer need to use your leaf blower.
Get out there and mow Now that you have done all that your mower should be ready to tackle the season in stride. It should run smoother and more safely too. Even better you have just saved the $200 to $300 fee it typically costs at least in my neck of the woods to have your lawn mower serviced professionally. So go on and get out there. That high grass needs cutting.
