Practical knowledge on the rehabilitation process of a rotary slasher

Project Abstract

This research project aims to provide practical knowledge on the rehabilitation process of a rotary slasher, a key agricultural equipment used for cutting grass and shrubs in farming operations. The rehabilitation of a rotary slasher involves a series of steps including inspection, maintenance, and repair to ensure its optimal performance and longevity. Through a comprehensive review of literature, practical guidelines and recommendations will be outlined for farmers and agricultural workers to effectively rehabilitate rotary slashers. The research will cover various aspects of the rehabilitation process, starting with an initial inspection to identify any visible damages or wear and tear. Subsequently, maintenance tasks such as cleaning, lubrication, and blade sharpening will be discussed in detail. The project will also address common issues that may arise during the rehabilitation process, such as blade replacement, belt adjustment, and gearbox maintenance. Furthermore, the research will focus on the importance of following safety protocols and guidelines while rehabilitating a rotary slasher to prevent accidents and injuries. Proper training on handling equipment, using personal protective gear, and ensuring a safe working environment will be emphasized throughout the project. In addition to the practical aspects of the rehabilitation process, the research will also explore the economic benefits of maintaining and rehabilitating rotary slashers. By extending the lifespan of the equipment and improving its efficiency, farmers can reduce operational costs and increase overall productivity in their farming operations. Overall, this research project aims to bridge the gap between theoretical knowledge and practical application in the rehabilitation of rotary slashers. By providing comprehensive guidelines and recommendations, farmers and agricultural workers will be equipped with the necessary tools and knowledge to effectively rehabilitate their equipment, ultimately leading to improved performance, longevity, and economic benefits.

<p> </p><p><strong>1.0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; INTRODUCTION</strong></p><p>Rotary Slashers is an agricultural machine, which is used for cutting unwanted grass. These rotary slashers are joined through jigs, fixtures &amp; dies, thus ensure joining accuracy as well as interchangeability. It has heavy duty gear boxes and rugged frame which can withstand rough and tough wild grass, anchored straw and bushes. It is designed for fast application to any type of 5080 HP tractor with three point linkage. (<a target="_blank" rel="nofollow" href="http://www.indianagrovision.com">www.indianagrovision.com</a>, 2018). &nbsp;</p><p>Rotary slasher are generally have an opening by the side of the housing through which cut grasses expelled. The blade is seldom Sharp enough to give a neat cutting point.The blade simply cut the grass resulting in brown tips.However the horizontal blades are easy to removed and sharpen or replace. Base on the energy source , the tractor power take off shaft is use to transfer power to the implement.</p><p>(<a target="_blank" rel="nofollow" href="http://www.ijeter.everscience.org">www.ijeter.everscience.org</a>, 2018).</p><p><strong>1.1 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; BACKGROUND OF THE STUDY</strong></p><p>This project deals with the rejuvenation of rotary slasher slasher which was broken down for a while in the workshop due to some mechanical fault. We aimed at restoring the rotary slasher to good operative,effective and also make it to serve the purpose.</p><p>Rehabilitation of rotary slasher means to the process involved in repairing and rejuvenation of a broken down rotary slasher in other to restore it back to normal working condition. Due to high global economic set back today, a lot of people find it difficult when it comes in term of rehabilitation of broken down machine, implement part or the machine as a whole and hence serve as an alternative to purchasing new one.</p><p><strong>1.2 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; STATEMENT OF PROBLEM</strong></p><p>A physical inspection was carried out on the scrapped and abandoned rotary slasher to access the problems of the implement.
