3. Blade Overview
This chapter discusses the various types of blades used in bulldozers, highlighting their characteristics, functions, and applications. Key performance metrics such as cutting ratio and load ratio are examined, alongside their implications for operational efficacy in different soil conditions. Additionally, the chapter outlines methods to enhance bulldozer productivity by reducing end spillage and describes factors impacting efficiency.

4.2Material Type
What we have learnt
- High cutting ratio indicates a blade's ability to penetrate hard soil efficiently.
- Blade capacity is determined by its dimensions and varies among different types of blades.
- End spillage can significantly affect productivity, and certain dozing methods can mitigate this issue.
Key Concepts
- -- Cutting Ratio
- The horsepower per meter of the cutting edge of the blade, indicating its effectiveness in penetrating soil.
- -- Load Ratio
- The horsepower per loose meter cube of material retained in front of the blade, reflecting the blade's ability to push material.
- -- End Spillage
- The material that spills off the ends of the blade during operation which can reduce overall productivity.
- -- Types of Blades
- Different blade configurations (e.g., straight, angle, U blade) designed for specific tasks and soil conditions.
- -- Dozing Methods
- Techniques employed to enhance the productivity of bulldozers while minimizing issues like end spillage.
