Description:TECHNICAL FIELD
[001] The present disclosure relates generally to a field of a working vehicle for agricultural operations. More specifically, it pertains to a compact, a light weight, and economical working vehicle which enables mechanization of small sized agricultural farms and benefits marginal farmers to perform variety of conventional agricultural operations.

BACKGROUND OF THE INVENTION
[002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] A working vehicle, such as tractor, is commonly used in every part of world including under-developed, developing, and developed countries for performing agricultural operations. In present scenario, working vehicle, such as tractor, is mostly used for agricultural operations in large agricultural fields. However, in under-developed and developing countries around 60% farmers are having small sized agricultural field being marginal land holders. The current range of working vehicles is not ideally suitable for the needs of marginal land holder because of its build, heavy-weight, and constraints in manoeuvrability. Also, marginal land holders are not able to afford such working vehicle.
[004] Presently, working vehicles available for marginal land holders are makeshift measures having technical and operational constraints, and inefficiencies in mechanization of conventional agricultural operations. Also, these makeshift solutions do not cover entire range of agricultural operations as done by conventional working vehicles.
[005] In an existing technology used in such makeshift measures for agricultural operations, a working vehicle provides mechanically operated three point hitch, and do not provide a mechanism for maintaining continuous operating depth of an implement during agricultural operation. Further, the existing technology does not provide power take off shaft thus disabling farmer from use of various rotary implements such as rotavator, thresher, water pump, potato digger, trench digger, sprayer, and the likes. Another disadvantage with the existing technology is that an operator needs an extra effort to operate three point hitch, and cannot automatically maintain the operating depth of the implements.
[006] In another existing technology, working vehicles, having a steering actuator with steering ratio ranging between 12:1 and 20:1, do not provide efficient turning which is required in small sized agricultural fields. Further, weight of such working vehicles is high. This reduces their fuel efficiency, and also increases cost thereby making it unaffordable and providing low return on investment to the marginal farmer. Another disadvantage is that the existing technology do not provide a device for maintaining operating depth of an implement.
[007] Therefore, there is a need to provide a compact, light-weight, manoeuvrable, fuel efficient, and cost effective working vehicle, which enables marginal farmers to perform a range of conventional agricultural operations including draft as well as rotary implements and haulage of agricultural produce for increasing output from same small sized agricultural fields.

[0010] Another object of the present disclosure is to provide a working vehicle for agricultural operations having a plurality of structural frames which are integrated in an arrangement to support steering actuation, to enable mounting of a prime mover assembly and an agricultural vehicle unit, and to incorporate an operator seat and various operating controls.
[0011] Another object of the present disclosure is to provide a working vehicle for agricultural operations which provides 1:1 steering ratio for efficient turning of the working vehicle in small sized agricultural fields.
[0012] Another object of the present disclosure is to provide a working vehicle for agricultural operations having a unit for disengaging drive of hydraulic pump from a prime mover assembly, thereby increasing fuel efficiency of the working vehicle during operations such as haulage of agricultural produce.
[0013] Another object of the present disclosure is to provide a working vehicle for agricultural operations having independent brake actuation for each of rear wheels to enable shorter turning radius during field operations.
[0014] Another object of the present disclosure is to provide a working vehicle for agricultural operations having simultaneous brake actuation for all the rear wheels combined during operations such as haulage of agricultural produce.
[0015] Another object of the present disclosure is to provide a working vehicle for agricultural operations having means to fix engine throttle position at a predetermined speed to enable constant speed movement of the working vehicle during agricultural operations in fields.
[0016] Another object of the present disclosure is to provide a working vehicle for agricultural operations having integrated load carrying platform for carrying loads such as agricultural produce.
