Challenges included developing a light four-cycle engine and an autopilot calibrated by GPS.
This four-cycle model can easily be reconciled the observations of the Schlesingers, Klingberg and others if we collapse the four into two.
Other impressive models so far include the 26-inch Yard Machines 31AM63EF700, $700, and 24-inch Craftsman 88955, $580, both four-cycle, two-stage models made by MTD.
Note that our ratings of string trimmers and leaf blowers (available to subscribers) do not identify whether an engine is a two - or a four-cycle type.
It's powered by a four-cycle overhead-valve engine and provides an 18-inch clearing width, 2 inches wider than that of the 38182/38172.
But results from the four such trimmers we tested demonstrate that four-cycle technology in string trimmers isn't the panacea you might think.
The John Deere BH25LE and Craftsman 79498 leaf blowers have a four-cycle engine. —
The Cub Cadet 4125, Craftsman 79614, and Troy-Bilt TB465SS string trimmers have a four-cycle engine.
Both models have four-cycle engines that are less likely to stall out when the blower ingests too much snow at once.
