What the specs work out to
Figures MowerFacts computes from STIHL’s own numbers — not published by the manufacturer.
Mowing time

- 1 acre3 h 9 min 2 h 13 min
- 2 acres6 h 19 min 4 h 25 min
About 189 min per acre at 0.32 acres/hour, mowing at 2.0 mph. The second figure is at the published 2.8 mph top speed (0.45 acres/hour) — faster than anyone really mows.

Needs at least 23 in of clearance.
Mowing times assume 0.32 acres/hour: deck width x 2.0 mph at 80% efficiency, which allows for overlap, turns and trimming. 2.0 mph is 70% of the 2.8 mph top speed STIHL publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 2.8 mph, shown so you can see it.
Fit uses STIHL's published overall width.
