Project Abstract

Abstract
The rehabilitation process of a rotary slasher is a crucial aspect of maintaining and optimizing the performance of this agricultural equipment. This research project aims to provide practical knowledge on the rehabilitation process of a rotary slasher, focusing on the key steps and considerations involved in restoring the functionality of the equipment. The study involves a comprehensive review of the common issues and challenges faced by rotary slashers, as well as an analysis of the best practices for rehabilitation. The first step in the rehabilitation process is to conduct a thorough inspection of the rotary slasher to identify any worn-out or damaged parts. This involves checking the blades, bearings, belts, and other components for signs of wear and tear. Once the damaged parts are identified, they need to be replaced with high-quality and compatible replacements to ensure the optimal functioning of the equipment. Another crucial aspect of the rehabilitation process is proper cleaning and maintenance of the rotary slasher. Cleaning the equipment helps remove dirt, debris, and other contaminants that can affect its performance. Regular maintenance tasks such as lubricating moving parts, adjusting belt tension, and ensuring proper alignment are essential for extending the lifespan of the rotary slasher. Furthermore, this research project highlights the importance of following the manufacturer's guidelines and recommendations for the rehabilitation process. Manufacturers often provide detailed instructions on how to disassemble, repair, and reassemble the rotary slasher, which can help ensure that the rehabilitation is done correctly and efficiently. In addition, the study explores the role of training and skill development in the rehabilitation process of a rotary slasher. Proper training on equipment maintenance and repair techniques can empower farmers and equipment operators to effectively rehabilitate rotary slashers on their own, reducing the reliance on external repair services and minimizing downtime. Overall, this research project contributes valuable insights into the practical knowledge required for the successful rehabilitation of rotary slashers. By following the key steps and considerations outlined in this study, farmers and equipment operators can enhance the performance, longevity, and reliability of their rotary slashers, ultimately improving agricultural productivity and efficiency.

Project Overview

 INTRODUCTION

Rotary Slashers is an agricultural machine, which is used for cutting unwanted grass. These rotary slashers are joined through jigs, fixtures & 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. (www.indianagrovision.com, 2018).  

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.

1.1                                                     BACKGROUND OF THE STUDY

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.

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.

1.2                                                     STATEMENT OF PROBLEM

A physical inspection was carried out on the scrapped and abandoned rotary slasher to access the problems of the implement. After inspection and diagnosed. It was discovered that the following faults were detected.

      i.           The oil seal was damaged

    ii.           The slip clutch safety guard was missing

  iii.           The blades is blunt, require resharpening

  iv.           The center hitch pin was missing

    v.           The bolts and nuts on the blade need replacement

1.3                                                     AIM AND OBJECTIVE

1.3.1                                                 AIM

      i.           The aim of this project is to acquire practical knowledge on the rehabilitation process of a rotary slasher

    ii.           To make the implement functional

  iii.           To highlight on the advantages of good maintenance culture

1.3.2                                                 OBJECTIVE

      i.           To inspect the implement

    ii.           To diagnose and detect the fauts in the rotary slasher

  iii.           To estimate the requirements for the rehabilitation

  iv.           To rehabilitate and test implement

    v.           To provide additional implement to the department.

1.4                                                     SIGNIFICANCE OF THE STUDY

Is to have practical knowledge and experience of what is been thought in the classroom and also have idieas on the maintenance to add to the number of good equipment in the department.

This project would not only help in the rehabilitating the rotary slasher, but will help in correcting the maintenance of the implement, broadens the students technical knowledge of the implement hereby increasing their interest the field.

1.5                                                     SCOPE OF THE STUDY

The scope of this project is the precurment, purchase and replacement of the defectives parts in the rotary slasher and to extend the functionality of the implement in the department.

1.6.1                                                 DEFINITION OF TERMS

      i.            MACHINERY

This is a group of powerful multipurpose engine powered machines or device on which implement are mounted or attached for their operations. This device require skills to operate, example tractors, bulldozer, milking machine, etc.They are often heavy duty machines adopted for large scale mechanized farming.

    ii.            EQUIPMENT

These are lower machines or advanced implements that require both skilled and unskilled labour for their operation.They range from simple hand held apparatus to complex ones designed a specific work.

  iii.            IMPLEMENT

These are higher and larger tools or devices that are attached to or mounted on animals or machines used in farming operation. Without the aid of these machines or animals,implements cannot function on there own.They are made up of material especially iron for a specific purpose in the farming operation.example ,ploughs, shearing blade,harrow, Rodgers,cultivators, tiller.etc that are attached to the tractor use in mechanized farming

1.6.2                                                 CLASSIFICATION OF IMPLEMENT

Agricultural implement can be further classified according to how the drive power from the power unite the can be further classified into four major unit namely.

                      i.            FULLY MOUNTED IMPLEMENT

Fully mounted implement are machines that drive all power required for work from the prime mover,such machine is mounted is mounted on the tractor’s three point linkage and can be lowered or lifted using a tractor hydraulics system. Example of fully mounted implement include rotary slasher,plough, subsoiler, disc harrow etc.

                  ii.            SEMI-MOUNTED IMPLEMENT

These is an implement that is partially supported by the tractor and partially supported by own wheel.such implement has only one pair of wheel, usually at the back while the front is supported by the tractor draw bar.example of such implement includes planter,sprayers,and fertilizer drills

                iii.            TRAIL IMPLEMENT

These are implement that is attached to the tractor through the draw bar which provide a towing or pull force but can not support the weight of the implement .such implement include tractor trailer use for transportation.

                iv.            SELF PROPELLED IMPLEMENT

This is a machine this is self propelled and has his own engine and tyre for support. It does not depend on the tractor for power and support.
