成果简介	NOVELTY - The system has an input drive extended from an engine driven hydraulic pump (1), and a steering unit comprising steering cylinders (3,4) operated at high and low revolutions per minute (RPM). The system is configured to achieve variable step less speed in a rotary tiller by step up or step down of the speed of the tiller without changing engine RPM by the pump driven through a power take-off (PTO) and pump displacement is controlled by an operator through a hydraulic control valve (8) such that variable flow and pressure drives a hydraulic motor (15) to achieve multiple speeds and torque at rotary blades, where variable speed range is achieved based on nature of soil when the vehicle is in moving condition without halting the vehicle. USE - Hydraulic controlled rotary tiller transmission system for use with an agricultural vehicle i.e. tractor. ADVANTAGE - The system achieves multiple speed ranges to cut different soil and field requirements, enables easy speed shift with a single control lever by operator or user. The system provides increased productivity, fuel efficiency, and versatility to various soil, crops and land conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating a hydraulic controlled rotary tiller transmission system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a hydraulic controlled rotary tiller transmission system. 1Engine driven hydraulic pump 3,4Steering cylinders 5Oil cooler 8Hydraulic control valve 15Hydraulic motor
