LH 765 G RAIN LOSS MONITOR – O PERATORS MANUAL & F ITTING INSTRUCTION
LH A GRO 7
RULE OF THUMB
From the above table it can be concluded that per 1 cm width of cut there may be
1 seed per driven metre.
As the loss usually lays in a 1 metre wide track behind the harvester the lost seeds
cover app. 1 m
2 .
A normal hand is about 1/100 m 2 . Acceptable loss therefore will be 1/100 of the
loss stated in the table.
Example:
A combine harvester of 17’ is used in a barley field yielding as stated above.
From the table it appears that acceptable loss (1%) is 510 seeds per metre.
Under the palm of a hand the accepted volume of seeds then will be:
510
100
= 5,1 seeds
