Seed planting gearbox
The W630 DV planter is equipped with
54 speed gearboxes, one or two
according to the model; this is to obtain
the desired planting rate.
It works in oil bath, It´s capacity is of 4
liters of SAE 30 oil.
In the beginning of every working
season it is recommended to check the
level and quality of the oil. It´s generally
used for several seasons, but in the
case of contamination by foreign objects
and humidity, oil may lose its qualities
and it must be changed.
If the oil were to be changed, remove
the B cap in the bottom of the gearbox
to drain the old oil, and replace oil
through the A. Figure 40.
The gearbox features a spring protecting device (C). In case anything jams, the device
springs out and no damage results. If necessary, adjust the spring-loaded device by
tightening or loosening hex bolt C, Figure 40. Setting should be such that the device may not
spring out under normal pressure but does spring out when the transmission turn jams.
Adjusting seed rate
The 54 speed gearbox allows adjusting seed rate to fit intended crop.
1- According to the type of seed and rate intended check the corresponding gear in Table I.
2- Look in chart II the shift selected, and position the levers A, B, C or D. As indicated in the
chart. (Figure 40).
To set the selected shift lever proceed as follows:
“Clutch” the gearbox by removing one of the levers from their lock point, A,B,C, or D. This is
achieved by moving one of the levers until it´s between one position and the other, and
turning the hand wheel D manually 3 or 4 turns always in the same direction, until it turns
freely.
In this condition, set every lever in their final position, leaving the “clutched” lever for the end.
Chart I besides of being in this manual, is also in the gearbox, E figure 40. Chart II also will
be found in this manual, and can be seen installed in the frame.
EXAMPLE:
If you want to plant corn at 20cm of distance between grains, this is equal to 5 grains per
meter, 50 grains every 10 meters.
In chart I we will find that these values are reflected in shift number 16.
