Valuable tips for precision spreading
Due to modern design and construction techniques and thorough testing on high
performance test rigs in ideal conditions, KUHN fertiliser spreaders achieve trouble-free
spread patterns.
In spite of careful manufacture, and even when using the unit correctly, variations in
application rates, or occasional problems, cannot be totally eliminated. Such circumstan-
ces can be caused by the following examples:
•
Varying consistency and flow characteristics of fertiliser or seed products (e.g.
variations of particle sizes, coatings, density, shape, causticity, moisture).
•
Lumpy moist fertiliser.
•
Wind drift. (When wind speed is high, stop spreading operations.)
•
Blockage or bridging (e.g. caused by foreign particles, bits of bag, moist fertiliser etc.!).
•
Undulating
fields.
•
Wear on components (e.g. agitator, vanes, metering components).
•
Defects arising from external influences.
•
Lack of cleaning or prevention against corrosion.
•
Incorrect pto speed or incorrect tractor speed.
•
Failing to carry-out calibration check.
•
Failure to check spread pattern (Practical Test Kit).
•
Incorrect machine set-up (incorrect unit attachment and disc vane setting).
•
3-point linkage not adequately restrained from side to side movement, or spreader not
exactly 90° to the direction of travel, or not exactly horizontal.
Before each operation, as well as during operation, check that the fertiliser spreader is
functioning correctly and the correct application rate and spread pattern is being achieved
at all times.
Rear fertiliser ejection distance equates to approx. ½ the working width. Total fertiliser
ejection width equates to approx. twice the working width in triangular spread pattern set-
up.
Use the hopper sieve (supplied, depending on country) to avoid output flow blockages
due to foreign particles or fertiliser lumps.
Check the spread pattern by using the Practical Test Kit.
No liability can be accepted for consequential losses or damages other than faults arising
from incorrect manufacture of the fertiliser spreader itself.
This liability exclusion also
means the total non-acceptance for consequential losses or damages due to
spreading errors.
Unauthorised alterations to the fertiliser spreader can lead to injury or
damages for which the manufacturer will not be liable.
Claims against the supplier for liability concerning personal injury and subsequent
consequential damages or property damage, which, according to product liability laws
regarding privately owned articles, have been caused by faults with the articles,
subjecting the supplier to liability, are not valid if such faults arise from the direct or
indirect consequences of wilful intent or gross negligence by the owner of the supplied
article, or any of the owners' employees, or other third parties. Further, liability claims
against the supplier are not valid if specifications supplied with the article, or made
available by the manufacturer of the article, offering specific protection, are missing and
that such protection would have protected the owner, operator or bystander against
personal injury and subsequent consequential damages or property damage.
