PREAMBLE OF THE INVENTION
The following specification particularly describes the nature of this invention and the manner
in which it is performed.

FIELD OF INVENTION:
This invention relates to a power tiller with adjustable handle, 360° nose wheel, easy ride on and off. Various applications in the field conditions require different type of handle positions of the power tiller to accomplish/carry out such various types of applications comfortably which reduce operator fatigue. Also the Power Tiller itself can be used as a versatile machine.
During uneven ground level or during bund crossing, the Power Tiller has to be handled properly. In such a situation, the Nose wheel act as a supportive member & Power tiller can be handled in proper manner.
As customer need a power tiller machine which will work in different type of field conditions & road conditions, easy ride on–easy ride off will enhance machine control as well improve productivity in field by covering optimum size of field.
BACKGROUND AND PRIOR ART:
Power tillers are amongst important farm machinery. With power tiller famer can prepare the land & carryout different applications as per need. This is a light weight machine as compared to a conventional four wheeled tractor, hence more suitable for light load farming applications. Currently, power tillers are being used in dry & wet land farming. Typically in dry land the usage is concentrated around post seeding operations like de-weeding, earthing up & secondary tillage applications. In wet land farming the power tillers are primarily being used for preparation of puddle before rice transplantation. During usage in the field, the user/operator walks behind this machine. In some cases this is also used on roads for transporting goods from field where road is in uneven conditions & control the power tiller with less effort is essential.
Need for this innovation:
The power tillers are targeted to be used in different farm applications. The user who operates this machine has to adjust according to the working position of the machine. The conventional power tiller has a fixed position of working handle bars, during ground engaging operations such as dry land rotary tiller or wet land tillage applications the operator

has no option but to bend & operate the machine. Adjustable handle bar is a solution to reduce operator fatigue & can be used in multiple applications.
The power tiller moves through the field which has different terrain profiles. Especially, when it goes downhill or while crossing the bund, there is a weight shifting tendency towards front side of the axle. In this condition, controlling the machine is difficult. Nose wheel act as a support & machine control will be easy.
Easy ride on – easy ride off arrangement is required for covering all corners of the field during field preparation. Since the farm size is not uniform and for better productivity user is supposed to cultivate each and every corner of the farm if easy ride on – ride off seating arrangement is not available it is very difficult for user to cover each and every corner of the farm. Some of the conventional power tillers offer seating arrangements but those are not easy to ride on and ride off.
OBJECTS OF INVENTION
The object of the present invention is to develop a power tiller which will allow the handle of the Power tiller to be adjustable in multi position handle bars.
Another object of the present invention is to develop a power tiller which will provide the nose wheel support towards front side of the power tiller axle for improved controlling the power tiller.
Yet another object of the present invention is to develop a power tiller which will provide the seating arrangement on Power Tiller for easy ride on & easy ride off will improve safety as well productivity of machine.

DETAILED DESCRIPTION OF THE INVENTION:
Handle bars are provided at both sides of the Power tiller i.e. handle bar LH & handle bar RH. These handle bars are mounted on hood with nut bolt type arrangement. Multiple holes or arculate slots are provided on both sides of hood for angular variation/adjustment of the handle bars. Handles can adjusted in these multiple holes or arculate slots as per need of the customer/operator.
There are two handle bars provided on this machine. These handle bars are fixed with bolted joints with the steering arm mounting cover (19). There are multiple hole positions or an arculate slot provided on the steering arm mounting cover (19). The handle bar LH (21) and handle bar RH (20) can be attached to the Steering arm mounting cover (19) in any of the multiple positions provided or along the arculate slot.
The Power tiller is further provided with a front support nose wheel (3) with rotational freedom of 360° (degree) to provide support during uneven ground level or bund crossing where the Power Tiller has to be handled properly. In such a situation, the Nose wheel act as a supportive member & Power tiller can be handled in proper manner. Nose wheel mounted at front side of power tiller on mounting provided on base frame. At the time of front support requirement front stand can be tilted down by using spring action. Due to spring action stand will remain intact with base frame & ease for operation. This feature will benefit the customer & enhance the control & safety of the power tiller. The detailed arrangement is given in Fig. 1. The nose wheel is optionally mounted towards front of the machine. This is foldable & can be deployed whenever required.

The Nose wheel (3) is mounted on a bracket (2) which is pivoted to the base frame assembly (1) by pivot bolts (7,8). The Nose wheel (3) can be moved into inactive or deployed position as per need. The spring (11) provides it the required resistance to retain it in deployed or inactive position.
The Power Tiller is provided with an easy ride on – ride off seat, mounted on the adjustable & detachable arrangement on the tail wheel. A seat mounting provision is given on rear side of the Power Tiller on tail wheel. The seat is positioned on bracket of tail wheel pipe at a predetermined angle which offers comfortable seating position to operator. Curvature shape is provided on both rear ends which provides easiness to the operator for easy ride on & easy ride off. This arrangement is basically provided for farm workers. This arrangement will enable user to enhance the utility of this machine.
The Power Tiller is provided with an unique ride on-ride off seating arrangement consist of parts as shown in figure (25 to 35). Height of the seat (25) can be adjusted by sliding and clamping the tail Pipe and bracket assembly (26) and clamp (27) on tail wheel sleeve assembly (28). The seat (25) arrangement enables user to get on & get off the machine as per his /her requirement. This facilitates the usage of the machine in corners of the farms.
Advantages to the user:
The user can adjust the handle bar in any of the position as per his need & comfort. This provides him with a flexibility to select the bar position & prevent bending or leaning over the machine during operation.
When the machine operates on slopes, bunds, uneven terrain, this front nose wheel provides additional support to the power tiller. This additional support helps in better control of the power tiller.
The Power tiller has unique but Easy ride on – ride off seating arrangement. This unique system provides comfort during field application and which in turn increases usage in terms of additional hours since user is not walking behind the power tiller. With it’s easy to ride on and ride off arrangement user can cover each and every corner of the farm their by increasing the output i.e. yield from the same farm. All these above features of the power tiller provides improved safety, ease and comfort in operation of power tiller.
