Abstract
A monitoring and control system for a tractor having a power-take-off (PTO) shaft comprises inductive sensors (9, 11) associated with toothed wheels (8, 10) on the input and output shafts respectively of a PTO gearbox (5). Each type of PTO shaft will carry a toothed wheel having a different number of teeth, and thus the ratio between the frequencies of the signals generated by the sensors (9, 11) is indicative of the type of PTO shaft and the ratio engaged in the PTO gearbox. This information can then be displayed on a control/monitoring unit (14) and also used to automatically control the engagement rate of a PTO clutch (6).
