OPERATION TRENCHING
31
Position the unit so the backhoe swing post is over the
centerline of the trench connection. Dig with the
backhoe at extreme swing positions, and in as close to
the stabilizers as possible. Pile the spoil on the
opposite side of the trenches.
Position the unit forward with the lift and crowd levers
so the two trenches can be connected. Pile the spoil
on the opposite side of the trench.
Side Slope Excavating or Trenching
Dig with the backhoe uphill wherever 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. Pile the
spoil from the slot on the low side.
When on the side of a steep slope, cut a level surface
along the uphill side of the trench with the loader.
Pile the spoil of the cut downhill. When digging, pile
the spoil of the trench uphill.
Dig field tile trenches progressively. As soon as one
trench is completed, have the workmen lay the tile.
Start the next trench, using the spoil to fill the previous
trench.
