Uniform Travel Speed for Manually Propelled Sprayers and Spreaders1
- D. D. Wolf and
- K. L. Edmisten2
Accurate application of solutions from sprayers and of granules from spinner spreaders requires a known constant speed of travel. Use of a commercially available pocket-size audio metronome is described to aid the operator in maintaining a desired speed. The metronome was powered by a 9-V battery and was carried in a shirt pocket. The tempo of the metronome was adjusted so that the operator traversed a known course length in a specified time period. for example, 24 s to traverse 26.8 m would be equivalent to 4 km h−1. The tempo set by the metronome varied depending on the stride length of the operator. Coefficient of variation with metronome pacing was 1.7% and without the metronome was 3.7%. A method for calibrating walking speeds using a metronome is described.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
