Is the 144cc engine powerful enough for thick St. Augustine grass? My old mower bogs down constantly in my Florida lawn during summer growth.
Hey Robert! The 144cc 4-cycle engine handles thick St. Augustine very well, especially with the 21-inch cutting deck. For dense Florida summer growth, we recommend setting the deck height one notch higher and making two passes. The 2-in-1 mulch mode chops clippings fine enough to feed back into the lawn! – Admin
