9.8.3. Loss of grass seed during transport
During transport, the machine leaves a trail of grass seed. This can result in vegetation between
paving stones and must therefore be avoided. Possible causes:
a. The seed flow slider does not close properly
b. The seed flow slider is open
c. The seed funnel is clogged
a. The most obvious cause is that the seed flow slider does not close properly after releasing
the yellow seed lever. This seed flow slider is switched to its closed position via a tension
spring. If this tension spring is broken or has come loose for a specific reason, the seed reser-
voir will not shut itself. Check the condition of this spring.
The seed flow slider is operated via a cable connected to the yellow seed lever. If this cable
encounters too much resistance due to soiling or deformation and does not retract when the
lever is released, the flow slider will stay open. The operator will quickly notice this, because
the seed lever does not spring back when released. Check and lubricate the cable guide.
It happens that an object has ended up in the seed and is jammed in one of the scattering
openings of the seed flow slider. As a result, the slide cannot close mechanically. Check that
the seed flow slider can move over its full range and remove the obstacle.
If, due to contamination of the guide slider, the seed distribution slider (e.g. due to deposits of
the coating of the grass seed) becomes stiff, the tension spring may not have sufficient force
to overcome this resistance and the seed distribution slider will remain open. Check the seed
flow slider can move and clean if necessary.
b. If, by mistake or due to a glitch, the seed outlet slider has been opened, it is normal for seed
to fall out of the seed distribution system in this way. Check the position of the slider and
close it again.
c. During operation, one or more seed funnels may become clogged at the bottom. This fills the
funnels with seed. If the seed funnel is unblocked again due to vibration or the drying up of the
blockage, the funnel will completely empty. This can also create a temporary trail of seed. Check if
the seed distribution system for clogged funnels.
9.8.4. Irregular seed pattern
When overseeding, you can observe the scattered seed in and around the grooves. Under normal
conditions, the seeds are uniformly distributed over the entire working width. If, however, you
notice certain areas with no distribution, or excessive or uneven distribution of seed, this can
have the following causes:
a. Empty seed reservoir
b. Incorrect flow setting
c. Clogged seed funnels
d. Problems with the seed flow slider
e. Malfunction in the drive
