Tractor hydraulic system pressure measuring device - has manometer connected to lifting cylinder and coupled to pointer movable over scale

摘要

The hydraulic pressure measurement system for a farm tractor has a manometer (17) which is connected with the pressure transmitter (15) or hydraulic cylinder (10) of the lifting device (4) and is fixed to the vehicle. The manometer has a plate (18) with a scale (25) which together with the pressure pointer, serves to indicate the total weight of the attachment implement (9). The plate is adjustably supported within the housing (19) of the manometer in relation to an operating lever (11) for the hydraulic lifting device (4).
