Working vehicle, particularly plant protective agent-spraying vehicle, has hydrostatic traction drive and internal combustion engine as primary drive assembly, which drives hydraulic pumps in hydraulic circuit

摘要

The working vehicle (F) has a hydrostatic traction drive and an internal combustion engine (1) as a primary drive assembly, which drives hydraulic pumps (3,6,12) in a hydraulic circuit (K1) and auxiliary loads (9,16,17,18) in another separate hydraulic circuit (K2). A brake valve arrangement (10) is provided in the latter hydraulic circuit.
