5. CONTROLS

The backhoe has two single lever controls plus two stabilizer control levers, located on the console control panel directly ahead of the operator. Following is a list of the controls from left to right, with the function of each. NOTE: You will find some functions will not work when operating simultaneous operations. If this occurs, move lever to center and operate functions individually.

NOTE: You will hear some noise coming from the valve whenever a port relief opens. This noise is normal during backhoe operations.

5.1. Boom & Swing:

Push lever forward, boom moves down, away from operator.

Pull lever back, boom moves up, toward operator. The Boom/Swing Control Lever has an added “float” function. A detent or stop should be felt when the lever is pushed forward to move the boom down. Pushing the lever forward more will overcome the detent and cause the boom to float, or move down or up freely, depending on the forces acting on it. When the lever is released it should return to the center, neutral position.

Move lever to the left, backhoe swings to the left. Move lever to the right, backhoe swings to the right. By moving the lever to one of the intermediate positions, the boom can be swung left or right at the same time as the boom is being raised or lowered, performing two operations simultaneously.

Boom & Swing

Crowd & Bucket

SWING LEFT AND LOWER the boom by moving the control lever forward and to the left.

SWING LEFT AND RAISE the boom by moving the control lever back and to the left.

SWING RIGHT AND LOWER the boom by moving the control lever forward and to the right.

SWING RIGHT AND RAISE the boom by moving the control lever back and to the right.

5.2. Left Hand Stabilizer:

Push lever forward, the LH stabilizer lowers. Pull lever backward, the LH stabilizer raises.

5.3. Right Hand Stabilizer:

Push lever forward, the RH stabilizer lowers. Pull lever backward, the RH stabilizer raises.

5.4. Crowd & Bucket:

Push lever forward, the dipper assembly moves out, away from the operator. Pull lever back, the dipper assembly moves in, toward the operator. Move lever to the left, the bucket curls in. Move lever to the right, the bucket extends out.

By moving the lever to one of the intermediate positions, the dipper assembly can be extended or retracted at the same time as the bucket is being loaded or dumped, performing the two operations simultaneously.

EXTEND AND LOAD the bucket by moving the control lever forward and to the left.

RETRACT AND LOAD the bucket by moving the control lever back and to the left.

EXTEND AND DUMP the bucket by moving the control lever forward and to the right.

RETRACT AND DUMP the bucket by moving the control lever back and to the right.

The two operations of the boom control lever, combined with the two operations performed by the bucket and dipper control lever, provide four simultaneous operations from the two levers, keeping cycle time to a minimum. NOTE: You will find some functions will not work when operating simultaneous operations. If this occurs, move lever to center and operate functions individually. In general, the direction of movement of a control lever corresponds to the movement of the operating member.

5.5. Operating the Backhoe

CAUTION: Equip your tractor with a ROPS frame for your protection. See your tractor/ROPS Operator Manual for correct seat belt usage.

1. Disengage transport locking pins before attempting to operate the backhoe. Store transport locking pins in holes provided in operator platform.

2. Operate from the backhoe operator’s seat only.

3. Lower the stabilizers until the rear of the tractor is totally supported by them note: rear tires should not come up off of the ground.

4. Do not dig near the stabilizers.

5. Do not touch overhead wires with any part of the backhoe.

6. Do not attempt to raise the tractor off the ground or move the tractor forward or backward using the backhoe dipper assembly or bucket.

7. Do not lose stability by swinging the bucket downhill when positioned on a slope.

8. Do not lower the backhoe boom using the “float” function. It w ill freefall, and could result in serious injury to bystanders or damage to the backhoe.

It is not difficult to become an efficient operator. Control lever operating decals are located on the valve cover plate assembly. Study these decals. They will assist you in becoming familiar with the controls. Smooth, light handling of the controls will result in the most efficient backhoe operation.

Operate the backhoe control levers to become familiar with their speed and movements. The engine speed and the size of the hydraulic system will determine the speed of cylinder operation. When powering from tractor systems with higher output than required, reduce engine RPM to obtain acceptable backhoe operating speed. Swing the boom several times to practice controlling the speed of swing. Do not operate the swing more than 45 degrees each way for the first few times, then gradually increase the arc.

The boom “float” function may be used during digging to eliminate down pressure when cleaning the bottom of a trench. The primary purpose of the boom “float” function is to protect the operator from serious injury in the event that some component of the backhoe would fail.

Best results are obtained by digging near the center of the swing arc so material can be dumped on either side.

As the operator becomes more familiar with the operation of the backhoe, it will be common practice to operate two controls at one time. For example, with the bucket extended and the dipper assembly extended, the boom control and crowd control can be operated together to bring the bucket toward the operator with down pressure on it. As the dipper assembly approaches the operator, the crowd and bucket controls can be operated to close the bucket and trap the material. At the end of the stroke, the boom and crowd controls are operated to move the load up and away from the operator to save time in clearing the excavation.

This dual operation of controls will speed and simplify the digging operation. Normally the two or more movements will not be equal or even simultaneous, but as the pressure within the cylinders changes, and the resistance on an operating member of the hoe lessens, it will begin to move. It is balancing the force of one member against the other.

NOTE: Actuating the bucket is the key to powerful digging. Operating the crowd and bucket controls simultaneously will insure a full bucket and prevent waste motion and time.

NOTE: If any handle begins to develop excessive play, or becomes misaligned in neutral or center position, it is an indication that control handle or linkages have become loose or worn. Replace or repair immediately.
