This document is a course project report for ME 203 Kinematics and Dynamics of Mechanical Systems from 2016. It discusses the design of a crop cutting mechanism with the following key points: - The project members are 5 students and the mentor is Prof. Tanuja Sheorey. - The topic of the project is a crop cutting mechanism that can be used to cut crops like jowar, tuar, and wheat, reducing labor costs and requiring only one person to operate it with low maintenance. - The mechanism's mobility is calculated to be 1 based on the number of links and joints.

3. TOPIC
CROP CUTTING MECHANISM

4. INTRODUCTION
This can be applicable for the cutting of the crop
such a Jwar, Tuar and wheat etc. It can reduce labour
cost due to the only one person can be handle with
low maintenance.
Crop cutting machine is a mechanical device. It
can be use for cutting the dry cut stalks of grain
break or covering of trunk tree.

5. ORIGIN
THIS MECHANISM IS EXTRACTED FROM THEORY OF MACHINE S.S. RATAN

6. MOBILITY CHARACTERISTICS

7. Cont...
MOBILITY (M) = 3(n-j-1)+j
where, n=no. of links
j=no. of joints
Here, n=6
j=7
So, M=1

8. DESIGN OF MACHINE

9. GENERAL BENEFITS
 REQUIRED LESS HUMAN EFFORTS.
 VERY REASONABLE FOR FARMERS.
 SIMPLE IN CONSTRUCTION.
 UNSKILLED WORKER CAN OPERATE.
 LOW COST.
