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.
Top 5 Lawn Mowers recommends the Sun Joe MJ401E to people with a small yard who dont want to spend a lot on a mower. The reviewer liked it overall for many of the same reason one might like any electric mower (no fossil fuels lightweight etc.) but he also noted that there were only three height positions with the lowest scraping the ground. And due to its 14-inch blade it takes longer to mow a lawn.
About 86% of the buyers who reviewed the Honda HRX217VKA on Home Depots website gave it four or five stars. Handyman left the most helpful review after using his mower for one year. He noted that its the best mower he is ever owned because of the adjustable speeds for the self-propel controller. He goes top speed and has to walk briskly to keep up. Other buyers remark that the mower cuts well after just one pass and doesnt leave stragglers clumps or lines. One buyer was impressed with how it could even handle unkempt grass over six inches high.
