18. Digging force
Tear-out force
(arm digging force)
Break-out force
(bucket digging force)

19. Bucket breakout force loss when using an quick fit or long tip radius
bucket.
The shorter tip radius bucket provide more digging force than the
longer.
Tip
radius
(A)
(B) (B)
% loss in bucket breakout force = ( B – A ) / B * 100
Bucket breakout force loss due to increasing the width of a bucket.
The narrower bucket provide more digging force than the wider.
% loss in bucket breakout force = ( B – C ) / B * 100
(B) (C)
Digging force effect
1. By bucket tip radius
2. By bucket width
