SWING RIGHT AND RAISE the boom by moving the lever back and to the right. 3. Crowd/Bucket: Push lever forward, the dipperstick moves out, away from the operator .
Smooth, light handling of the controls will result in the most efficient backhoe operation. Operate the backhoe control levers to become famil- iar with their speed and movements. The engine speed and the size of the hydraulic system will deter- mine the speed of cylinder operation.
CAUTION T o avoid possible injury , observe the following safety rules when transporting the backhoe: 1. AL WA YS engage safety locks as shown on Figs. 1 and 3 when transporting backhoe. 2. TRA VEL SLOWL Y over rough terrain, on hillsides, and around curves to prevent tipping.
General Operations FILLING THE BUCKET Control the bucket attitude throughout the digging cycle to keep teeth at the proper angle for best penetration. This will minimize dragging and scraping the bucket through the ground.
General Operations SIDE SLOPE EXCA V A TING OR TRENCHING Dig with the backhoe uphill whenever possible. Level the backhoe on slopes with the stabilizers to dig plumb trenches, or use the backhoe or loader to cut a level slot for the uphill wheel and stabilizer .
fully several times to purge the system of air . Hydraulic System Hoses Oil leaks in the pressure side of the system can be located by carefully inspecting the external area of the hoses and fittings. Check the return side of the system for leaks by examining the oil in the reservoir .
TOOTH REPLACEMENT Bolt-On tooth points, when worn, can be replaced by removing the hardware that connects it to the cutting edge. Install new tooth and replace hardware if nec- essary . (Figure 5) Roll-Pinned tooth points, when worn, can be replaced by driving out the roll pin with a hammer and punch.
REMOV AL FROM TRACT OR - ST ORAGE The backhoe is self-assisting during the installation and removal procedures. For removal and storage, follow these steps: 1. Install the swing safety lock pin as shown in Figures 1 and 3. 2. Stretch out the boom, dipper stick and bucket as shown in Figure 9.
ST ABILIZER P ADS The backhoe is supplied with flip-over stabilizer feet as standard equipment. They are suitable for most backhoe work and generally are all that is ever required. However , foot pad kits are available as options. These kits bolt to the standard feet and increase the versatility of the backhoe.

identical fitting to “In/Pressure” port of bulkhead con- nection. Orient fittings so that free ends of fittings point horizontally toward center of backhoe.
Figure 18 32 valve or other accessory valve is connected to the tractor system, and whether the tractor has an open- center system (constant pumping of oil to control valve and back to reservoir) or a closed-center sys- tem (no flow of oil until there is a demand at one hydraulic cylinder).
33 Since the Power Beyond Kit is used with open-cen- ter tractor hydraulic systems, oil constantly flows from the pump, through the backhoe valve and the loader valve or other accessory valve, and then to the reservoir. See further in this manual for instruc- tions on proper assembly.
Hydraulic Hook-Up (2175, 2185, 2195) For Tractors With Closed-Center Hydraulic Systems (Figure 21) There are two basic types of hydraulic systems, open- center and closed-center. The open-center system con- stantly pumps oil through the hydraulic cylinder operat- ing valves and returns the oil to the reservoir.
35 POWER BEYOND KITS FOR TRACTORS WITH OPEN-CENTER HYDRAULIC SYSTEMS General Description A power beyond application is required to convert a hydraulic valve so that pressurized oil can be directed to another “open center” valve.
