(ON SLIDE #218) 8. BACKHOE LOADER (1HR) INTRODUCTION: a. Fast-acting, variable-flow hydraulic systems and easy-to-operate controls give hydraulic excavators the high implement and breakout force to excavate trenches, the precision to set pipes, and the capacity to back fill. The 420DV operates on these principals. It has the precision to work in tight places and the mobility to move quickly from job to job. (ON SLIDE #219) Use: b. The backhoe is best suited for trench excavating, it can dig well below the unit's wheels. A large variety of booms, sticks, buckets, and attachments give excavators the versatility to excavate trenches, load trucks, clean ditches, break up old concrete, install outlet pipes, and numerous other jobs. (ON SLIDE #220) Classification: c. Horsepower classifies Backhoes and excavators. The Backhoe Loader is rated at 88 horsepower. Generally speaking, the greater the horsepower the greater the output. (ON SLIDE #221) Characteristics: d. The 420E IT is a hydraulic, rough terrain Backhoe Loader, equipped with a manually control all wheel drive able to negotiate a maximum grade of 35%. It comes equipped with a front bucket and a backhoe bucket. (ON SLIDE #222) Operation: e. the 420D is used primarily for below ground level excavation, a survey should be conducted for
