Do not attempt to modify the mounting in any way. Incorrect mounting or modifying of the backhoe 3-point mounting could allow the backhoe to raise up during use, resulting in injury or death. DO NOT attempt to raise the backhoe with the 3-point hitch. The backhoe center links along with the hitch lock out arms make the backhoe a solid mount that is immovable. -
Page 14: Backhoe Operation
Backhoe Operation Levers The backhoe is equipped with two hydraulic stabilizers that keep the backhoe in place and stabilize digging especially while dumping to the side. Digging is more effective with stabilizers and should be used during digging. Stabilizers extend wider than tractors rear wheels giving balance to digging. -
Page 15: Excavation
Excavation When operating the backhoe, smoothness of technique should be strived for at all times. Smoothness will come with experience and practice at feathering the controls. Establish a flowing digging cycle to increase operator efficiency and save unnecessary wear on the machine. Observe the following points to obtain the best results and to fully utilize the digging force of the backhoe. - Page 16 sides of the bucket to scrape off any high spots. Dislodge any exposed rocks if they seem loose. When finishing walls, finish the far wall by curling the bucket out, crowding the dipperstick out, and forcing the bucket down. To finish the closest wall, lift the bucket up and curl it in. Once the sides are cleaned up, finish grading the bottom of the excavation.
