The present disclosure is directed to broadcast spreaders, and more particularly, to a broadcast spreader which may be used in a push configuration and converted for use in a tow configuration.
Presently available material spreaders are used for spreading material such as grass seed, fertilizer, sand or ice melters, for example, over the ground in a controlled spread pattern. The material spreaders also control the flow rate of the material.
There are presently available material spreaders that are capable of being pulled and pushed. However, such spreader do not include all of the parts necessary to convert from a push configuration to a pull configuration and then back again. Presently available material spreaders require that certain parts used in one configuration be removed and replaced with different parts for use in the other configuration. The parts which are not used in the one or the other configurations must be stored in a separate location. A major disadvantage of such presently available material is that the parts which are in storage are often lost and increases the time and complexity of the conversion.
Therefore, there exists a need in the art for a broadcast spreader which can be converted from a push configuration to a tow configuration using only the parts connected to the broadcast spreader that can also be manipulated without tools. Such a broadcast spreader is advantages in that the conversion can be accomplished quickly and without tools. Further advantageous include a broadcast spreader that is inexpensive, easy to convert and does not require tools for any disassembly or assembly thereof.
Certain embodiments are shown in the drawings. However, it is understood that the present disclosure is not limited to the arrangements and instrumentality shown in the attached drawings, wherein:
For the purposes of promoting and understanding the principles disclosed herein, reference will now be made to the preferred embodiments illustrated in the drawings and specific language will be used to describe the same.
