My old lawn mower died, the engine won’t start and if it try to start died immediately, I flushed the fuel, cleaned the carburetor, replaced the spark plug, the oil still look good and full, but it just wont’ start, so wasted the whole I decided to get a new one and sell the old one for spare parts I think combustion engine something inside the engine is not working correctly. Anyhow, I searched and decided to try a self propelled lawn mower, the idea is the lawn mower drive or roll on its own using the engine power, whether it use more gas or not I’m not sure but guess what? it’s working great! I got the Toro 22 in. High Wheel Variable Speed Self-Propelled Gas Mower – 20371 from Homedepot and it work great, I have a steep slope in the back, so this thing help me greatly, I wonder if last for a long time though. Highly recommend, I think it’s easy to get the hang of it, there’s a extra lever where you can control the propelled speed, some drive in front wheel some drive in the back, I prefer front because it will be easier for me to turn by push down on the mower.
