Fertilizer distribution
Procedures to change the sprockets
IMPORTANT
NOTE
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).
Move the lever to relieve the
chain tightener and lock it using a pin.
Manually displace the set of
sprockets in the shaft and align the
chosen sprocket with the chain.
Release the lever to loose the
lock pin.
• 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 damage to the spring and
shafts, never apply excessive torque when
tightening.
• 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 the 'Practical
test for seeds and fertilizer distribution' page.
