Abstract

PURPOSE:To read easily the speed and the speed change position of each part at a glance, by operating and displaying the speed of each part of the vehicle on the basis of the engine rotation number and the speed change position of a speed change gear mechanism in the speed detecting device for a tractor or the like. CONSTITUTION:The rotating speed of an engine 1 of a tractor or the like is detected by a rotating speed detector which is not shown in figure. The switching for speed change of speed change gear mechanisms such as a main speed change gear mechanism 9, an auxiliary speed change gear mechanism 14, a creep speed change gear mechanism 19, and a PTO speed change gear mechanism 30 is operated by operating shifters 7a, 13, 18, and 29 with shift levers 45-48. Their speed change positions are detected by switches Sm1-Sm6, SS1SS2, SC1SC2, SP1 SP2, etc. The rotating speed of each part is operated and displayed on the basis of the engine rotating speed and the speed change position of each part.
