Overview of mathematical mowing values: (mowing performance per hour)
R40Li 30 m²; R70Li 45 m²; SILENO 56 m²; SILENO+ 56 m².
In order to calculate the required mowing times per day, taking into account
individual needs, there are very simple calculation methods.
Our example assumes a lawn area of 150 m² that is to be mowed
A
7 days per week (daily mowing)
B
5 days per week (intensive use of the lawn at weekends, excluding
Saturday and Sunday from the mowing cycle)
Example
A
Daily active time = lawn area : mowing performance
E.g. R40Li: 150 : 30 m² = 5 hours of active time
or SILENO: 150 : 56 m² = 2.7 hours of active time (rounded to 3 hrs)
Example
B
Active time on 5 days/week (e.g. R40Li, 150 m
2
lawn area)
Step 1: Lawn area : mowing performance = daily active time
(150 : 30 = 5 hrs)
Step 2: Daily active time x 7 days = required, maximum active time for
this area (5 x 7 = 35 hrs)
Step 3: Reduction to 5 days (exclusion of Sat/Sun) max. active time :
5 days (35 : 5 = 7 hrs)
