Maximum Acreage per Hour (APH) Capacity

Match deck width with max mowing speed of your Grasshopper mower to determine max APH.

Maximum forward speed (mph)
7.5 mph 8 mph 8.5 mph 9 mph 9.5 mph 10 mph 10.5 mph 11 mph
41" 2.80 -- -- -- -- -- -- --
42" 2.86 3.05 -- -- -- -- -- --

72" 4.91 5.24 5.57 5.90 6.22 6.55 6.88 7.20

APH = MPH x Deck Width ÷ 110 (accounts for 10% overlap on each pass)



Hectares Per Hour (HPH) Capacity

Match deck width with max mowing speed of your Grasshopper mower to determine max KPH.

Maximum forward speed (kph)
Cutting Width (cm) 12.1 kph 12.9 kph 13.7 kph 14.5 kph 15.3 kph 16.1 kph 16.9 kph 17.7 kph

182.88 (72 in.) 1.99 2.13 2.26 2.26 2.52 2.65 2.78 2.92

HPH = KPH x Deck Width ÷ 1110 (accounts for 10% overlap on each pass)

Volume, moisture, mulching and ground roughness are some of the factors that determine true mowing speed from maximum forward speed. Maximum APH/KPH assumes perfect mowing conditions, generally defined as flat, even terrain, no hills or slopes, few obstacles, few turns, low moisture (after irrigating or rains) and minimal cutting volume (higher mowing heights). Adjust mowing speed to specific mowing conditions to optimize mower performance.
