a. Empty seed reservoir:
During overseeding, you may forget about the seed level. As the seed reservoir is almost
empty, the auger will not carry enough seed through the distribution channel, causing the
seed pattern to become irregular and the spreading will eventually stop. Refill the seed re-
servoir with seed.
Please note: drive a few meters forward to fill the seed distribution system
back up with seed and obtain a stable seed image.
b. Incorrect flow setting:
As described in '§ c. Setting the seed flow rate on page 42' a flow setting in the red zones
on the sowing chart will result in an imperfect seed image. Correctly set the seed flow.
c. Clogged seed funnels:
During operation, one or more seed funnels may become clogged at the bottom. After a
while, this blockage may disappear by itself, causing the accumulated seed in the funnel to
suddenly be scattered, with too much seed scattered in one particular spot. Check the seed
distribution system for clogging.
d. Problems with the seed flow slider:
As described in'§ 9.8.3. Loss of grass seed during transport on page 62' there are nu-
merous causes that cause the seed flow slider not to switch to the desired position and thus
give a distorted or irregular seed pattern.
e. Malfunction in the drive:
The seed distribution system works using augers that distribute the seed from the seed
reservoir over the width of the machine. These augers are driven by a chain and run syn-
chronously with the machine's operating speed. There is a coupling to activate the drive. If
the drive on this auger fails, the supply of seed will stop and the sowing will eventually stop.
Possible causes of interruptions to the drive:
• Dirt build-up between the two gear wheels of the auger shafts, preventing rotation.
• Slip on the coupling pulley. If the pulley slips on the belt that carries the transmission to
the augers, they are no longer driven. Check the cable and cable tension, degrease the
pulley and check the condition of the belt.
• If a gear wheel has come loose from the auger drive, the key may have failed. As a
result, the drive fails.
• If the torque limiter slips, not only the drive to the traction roller but also the drive to
the seed distribution system will fail.
• If the spring of the chain tensioner is broken, the chain becomes too loose and can run
over the toothing in the floating chain sprocket before the auger drive.
• If the chain is broken, the drive to the traction roller and the seed distribution system
will fail.
• If the drive belt of the gearbox slips, the drive of the traction roller and the seed distri-
bution system will malfunction.
