29.5 HANDLING TRAPEZOIDAL BUCKET
This bucket is used to dig trapezoidal ditches on paddy fields, farm-
land ect. and can dig 3 types of ditch gradients ( 45
o
, 40
o
and 38
o
) when
a movable plate is attached.
• The mounting position of the movable plate varies depending on
whether the ditch gradient is 45
o
, 40
o
or 38
o
.
How to perform excavation
Operate the boom, the arm and the bucket to make the line A of the
side-plate of the bucket vertical.
The guide plate B to check this position is installed beside the bucket
pins. Accordingly, hold this plate horizontal when digging.
Ditch gradient of 45
o
Attached the bucket only or the movable plate by selecting the re-
lated ditch holes. Perform digging by the above method.
Ditch gradient of 40
o
or 38
o
Attached the bucket only or the movable plate by selecting the re-
lated ditch holes. Perform digging by the above method.
Even if the trapezoidal bucket is provided with the movable plate, al-
ways perform digging with the bucket side face perpendicular to the
ground.
