Attach the appropriate couplers to their corresponding hydraulic hoses. See your skid steer owner's manual for proper identification of auxiliary hydraulic coupler flow.

  • Page 39: Trencher Installation

    TRENCHER INSTALLATION 617 TRENCHER GENERAL INFORMATION The following instructions will help you to mount your trencher on your skid steer. The trencher uses the skid steer's quick-change attaching system for ease on installation. Therefore, if you know how to attach the skid steer loader bucket, attaching the trencher should prove no problem.
  • Page 40 TRENCHER INSTALLATION 617 TRENCHER Tilt the toolbar back to hook the trencher onto the toolbar. It may be neces- sary to lift the loader arm somewhat. Set the quick-change attaching lock to the locked position to secure the trencher. It may be necessary to raise, lower, or tilt the toolbar in order for the trencher mount and toolbar to properly align so the locking mechanism can be activated.

  • Page 41: Operating Instructions

    617 TRENCHER GENERAL INFORMATION Simplicity of operation is one of the key features of the 617 trencher. The trenchers themselves have no controls, just a few adjustments to check. It is impor- tant however, to be familiar with, and know the controls and adjustments on both the trencher and the skid steer.
  • Page 42 OPERATING INSTRUCTIONS CONTROLS 617 TRENCHER TILTING THE TRENCHER Tilt the trencher unit up or down by tilting the toolbar / attachment plate back or forward through its skid steer control. We recommend a 60° digging angle for general trenching as measured from ground level (the horizon). (See Figure #2)
  • Page 43 Lowering the trencher will cause the auger to lower, moving the spoil away from the trench. The built-in skid shoe on the 617 trencher will prevent the auger from being lowered to the extent that the auger itself starts to dig in the ground as this will greatly reduce efficiency.
  • Page 44 OPERATING INSTRUCTIONS CONTROLS 617 TRENCHER It should be noted that raising or lowering the trencher to change the auger height will also change the trenching depth. You will need to compensate for this by changing the tilt of the trencher down or up accordingly. (See Figure #3)
  • Page 45 OPERATING INSTRUCTIONS CONTROLS 617 TRENCHER FIGURE #4 SET SCREW CRUMBER BAR MAINFRAME CRUMBER BAR TUBE JAM NUT CHAIN TENSION ADJUSTMENT When trenching, the digging chain tension should be adjusted so that the chain is as loose as possible, without jumping off the sprocket or idler wheel.
  • Page 46 OPERATING INSTRUCTIONS CONTROLS 617 TRENCHER This procedure must be done simultaneously to both adjusting bolts to prevent the boom from becoming wedged onto its mount. CAUTION! Never work on, or make adjustments to any part of the tren- cher while the unit is running. You could get caught in the digging teeth which could cause severe injury or death.

  • Page 47: Operating Techniques

    OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS GENERAL INFORMATION The design of your trencher makes it relatively simple to use. With the help of the information in this section and a little practice you should become proficient in it's operation in no time. Observe the following points to obtain the best results with the least amount of wear on the machine.
  • Page 48 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS Locate the trencher on the mount with the side shift mechanism (as explained earlier in this section) where it will be most efficient and easy to use. Mark off the area to be trenched out. This can be done with pow- dered lime, chalk, or a guide string and stakes.
  • Page 49 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS CAUTION! When lowering a moving digging chain to the ground the force of the teeth grabbing the ground will try to pull the trencher suddenly forward. Be prepared. Have the brake on the skid steer set to help counteract the force.
  • Page 50 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS FIGURE #8 CREEP IN REVERSE LOWER When trenching, remember to keep in mind the spoil placement. Position the trencher so that the auger floats at ground level to move spoil away from the trench. (See Figure #9) FIGURE #9 NOTE DIGGING ANGLE SPOIL PILE...
  • Page 51 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS Raise the trencher so that the auger rides above the ground level to leave the spoil beside the trench. The higher the auger, the closer to the trench the spoil will be placed. You may find that it generally takes less power to run the digging chain if the auger runs 3"...
  • Page 52 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS TURNING WHILE TRENCHING Gradual turns can be made while trenching. However, the tightness of the turn is directly proportional to the angle and length of the boom. In other words the greater the angle of the trencher boom to the ground level, the sharper the turn that can be trenched.
  • Page 53 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS MAKING SHARP TURNS To make sharp turns and 90° angles you will have to dig two trenches. Dig the first trench as you normally would. Then reposition the unit and dig the second trench at the appropriate angle. Be sure to take into account the extra lead-in space needed for the trencher to get down to the desired trench depth.
  • Page 54 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS TRENCHING WITHOUT THE CRUMBER ASSEMBLY WARNING! The crumber bar and crumber shoe assembly are there for a reason, YOUR SAFETY! There are a few instances where removal may be necessary however. In these cases operate with extreme caution.
  • Page 55 OPERATING INSTRUCTIONS OPERATING TECHNIQUES SKID STEER TRENCHERS ENDING A TRENCH When you have dug your trench, remember that the trencher boom is at an angle, and that you must continue trenching until the end of the boom has dug past the proposed end of the trench. Once the end of the trench has been dug, keep the trencher running and lift the skid steer loader arms to lift the unit clear of the trench.
