Preparing For Operation

Preparing The Backhoe

Unlock the boom lock. You may have to raise the boom in order to relax the tension on the lock.

Preparing The Tractor

Move the tractor’s gearshift lever to a neutral position. Set the engine throttle to the correct RPM. For added stability, lower the front-end loader to the ground (if equipped). Move the draft control lever to the bottom- most position (Refer to your Tractor Operator’s Manual for Draft Control Terminology). If you are using an independent hydraulic system, engage the PTO.

Operating The Backhoe

IMPORTANT: If you are not familiar with the operation of the Backhoe, DO NOT PROCEED until you have studied the following “Transporting the Backhoe” section.

Transporting The Backhoe

!CAUTION!

While traveling with the backhoe, the tractor must have at least 20% of the combined tractor and backhoe weight on its front wheels. Add additional front-end weight, if necessary, to meet this requirement. This is necessary in order to maintain complete control of the tractor during travel.

!CAUTION!

Operate the backhoe only from the backhoe operator’s seat. Be sure to place your feet on the footpads during operation. This protects them from injury that could result from moving parts.

!CAUTION!

For tractors with a top link draft control system, make sure the draft control is in its heavy position. It is very important to prevent the top link from exerting pressure that may activate the draft control system. Continued operation with the draft control system activated can cause overheating of the hydraulic fluid and can cause tractor hydraulic pump failure. Put the draft control lever to the bottom of the quadrant.

When loading or unloading from the trailer, you may need to extend the dipper stick out to keep the bucket from dragging. Refer to Figure 2-1.

Your backhoe comes equipped with a transport lock. See Figure 1-6 on page 14. This transport lock should be put into proper position anytime you are transporting your backhoe. To ready your backhoe for transport, perform the following:
