FAQs
Q: What is the Ronix 4446 Gasoline Lawn Mower designed for?
For both home and commercial lawn care, the Ronix 4446 is a strong, gasoline-powered lawnmower. Its sturdy steel blade and height-adjustable cutting mechanism effectively trim medium-to-large lawns with a neat, level finish.
Q: What type of engine does the 4446 use?
A powerful 300W petrol engine that delivers consistent power and fuel efficiency powers the Ronix 4446. It is made to start easily, run reliably, and last a long time with the right upkeep.
Q: How do I stop the engine?
To instantly halt the engine and blade motion, release the safety control lever. To stop leaks during a long-term shutdown, turn off the fuel valve.
Q: How do I adjust the cutting height?
There is a central height adjustment lever on the mower. To raise or lower all wheels at once to the grass height you choose, move the lever to one of several preset positions.
Q: Can I use the Ronix 4446 on wet grass?
Wet or soggy grass should not be mowed. In addition to decreasing performance and raising the chance of slipping, wet grass can jam the cutting deck. For optimal performance, mow on dry ground at all times.
Q: How often should I sharpen the blade?
Sharpen the blade every 25–30 hours of mowing, or if grass is being ripped instead of being cleanly cut. The spark plug should always be disconnected before doing any blade maintenance.
Q: Does the mower include a grass collection bag?
Indeed. The Ronix 4446 comes fitted with a sturdy rear grass collection bag for efficient clippings handling. Depending on your preference, you can also remove it for side or rear discharge mowing.
Q: Can I use ethanol-blended gasoline?
Fuel with up to 10% ethanol content is acceptable (E10). Higher mixes, such as E15 or E85, should not be used since they can harm fuel system components.
