Operation
4
Set-up
1.
Before making any adjustments to the Par-
allelogram Presswheels read and under-
stand the operating instructions for your
implement.
2.
Set the desired packing force on the
presswheel tyre by changing the positions
of the extension spring retainers. Moving
the spring retainer rearwards increases
packing force.
3.
Initially set the sowing boot depth to posi-
tion “F”.
If noted from previous use set
the sowing boot depth to the correct posi-
tion.
4.
If installed, the mudscraper should have
approximately 3mm clearance on the
tyre.
5.
Set the implement depth stops to achieve
desired digging depth (and fertiliser
depth).
6.
Sow at least 50 metres with the implement
and the Parallelogram Presswheels at the
desired sowing speed with product flowing
at desired rates.
7.
Stop the machine. Check sowing depth and
adjust sowing boot as necessary. Sowing
boot adjusts in 5mm increments. Repeat
steps 6 and 7 until desired sowing depth is
consistently achieved.
Note: For best results, the sowing boot needs
to be adjusted on commencement of each job
when the machine is at working depth in the
soil to obtain optimum seed placement. Check
and re-check during operation.
Caution:
there is a limitation to maxi-
mum depth obtained with the sowing boot.
Depth will vary with soil type, moisture content
of soil, speed of travel and type of digging
point. Never adjust sowing boot depth below
the primary digging tool!
Operation
When working with your frame mounted
presswheels, follow all operating guidelines in
the Implement manual and regularly check for:
▪
Blockages due to mud, stubble, etc.
▪
Wheels can freely rotate.
▪
Even tyre wear and/or damage.
▪
All hardware in place and tight.
▪
Kinks/blockages in sowing tubes
▪
Point, boot & mud scraper wear
Be safety conscious during every operation
with your machine. Ensure bystanders are not
too close or riding on the implement when
working, raising or lowering machine.
Maintenance
10 hours (Daily)
Check for uneven tyre wear or damage, ensure
there is no material build-up on presswheels,
arms, sowing boots or mud-scrapers.
Check for kinks or blockages in sowing tubes,
manually run product through the distribution
system whilst stationary and ensure product is
being dispensed from each sowing boot.
100 hours (Weekly)
Grease the four hardened steel pivots. In ex-
treme dusty conditions pivots should be
greased at 50 hours or twice weekly. Use any
lithium based, extreme pressure general pur-
pose grease containing approximately 10%
weight of molybdenum disulphide.
Check wheels can freely rotate, observe wear
on point, sowing boot & mud scraper and re-
place as necessary. Check all hardware is in
place and tight.
