Problems solved by technology

[0007] However, in order to keep the PTO shaft rotating, the transmission case has a divided structure, which increases the number of parts, and requires time for maintenance, such as disconnection of each part and detachment of the clutch mechanism from the main frame, etc. and labor issues
[0008] In addition, by using a dry clutch, although power loss is suppressed, wear tends to occur, and there is a problem that the frequency of replacement becomes high.

Abstract

Provided is a work vehicle that is easy to maintain. Provided is a work vehicle. The field management device is provided with a traveling vehicle body (1 '), a work device for performing management work in a field, and a gearbox (20) for transmitting traveling driving force and work driving force, the gearbox (20) is provided with a front shell (21) equipped with hydraulic components (25, 26), a rear shell (23) equipped with an HST (30), and a central shell (22) equipped with a traveling transmission component and a work transmission component, and the central shell (22) is fixed to the traveling vehicle body (1').

Description

technical field [0001] The present invention relates to a work vehicle such as a chemical dispenser that has a spray boom for spraying chemical liquid at the front of a machine body and performs spraying of chemical liquid and the like. Background technique [0002] The work vehicles shown in existing Patent Documents 1 and 2 have: a front transmission that receives driving force from an engine; a dry clutch that turns ON / OFF transmission from the front transmission toward the transmission downstream side; and a rear transmission. The box transmits the driving force to the driving system and the operating system such as the boom sprayer. The front gearbox is provided with a PTO shaft (constant PTO, real-time PTO) that transmits the driving force to the plant protection pump. [0003] By providing the PTO shaft in the front transmission, the dry clutch can be disengaged to cut off the power transmission to the rear transmission, and the driving and work can be stopped, and th...
