Studies on the Recording Slip Meter for Wheel Tractors (1)

Abstract

In order to measure the slippage of wheel tractors at fields, a recording slip meter which could simply measure it has been developed.
The principal parts of this meter (Fig. 1) are composed of friction disks which regulate the ratio of front wheel radius to rear one, of differential gear by which the slipped revolutions were taken out and of recording apparatus.
When examined with a wheel tractor on an asphalt pavement, the characteristics of this meter were almost regarded to be satisfied.
