Adjustments and operations
Fertilizer distribution
The fertilizer distribution is made through the augers and the different rates are adjusted
by the sprocket combinations of the drive shaft {C} (14, 18, 22, 26, 30, 34 and 38 teeth)
and driven shaft {D} (14, 18, 22, 26, 30, 34 and 38 teeth).
Procedures to change the sprocket
See the different amounts of fertilizer distributed for several
spacings, according to the sprocket combinations.
The seed and fertilizer distribution tables of this manual must be used
as a reference to start the planter adjustment. Factors such as the
slippage index of the planter wheels (skidding), working speed, tire
inflation, field conditions, seed type and others can make the values
differ from the ones in the table. Therefore, it is always indispensable
to make the practical distribution tests, as indicated on page 41.
IMPORTANT
The cone bolts on the sprockets handling
"TRA" are pre-adjusted on the factory,
allowing to change the sprockets without
using any tool.
In case of any sliding motion on the cone
shaft, just release the counter nut and turn
around the bolt to re-lock.
In order to avoid damages to the spring
and shafts, never apply excessive torque
when tightening.
