Parameters for this device:
Wheel diameter 30cm and spread 42cm.
-> A square surface is worn to 2.5 turns of the wheel or "sprinkled".
For dosing measure, I then put the car in a bucket, the wheel turned 10x (equivalent to 4 sqm) and then landed in the bucket crowd fertilizers weighed. Result divided by 4 gives output per square meter.
With adjustment u. New measurements I have cast. 3 Meßdurchgänge needed. Note: The ratio of Adjusted "stray stage" at the scale of the amount setting for discharged amount is not linear! Therefore, for each agent to be discharged / seed new "turn".
Hope it helps the one od. Other here ...
For me, the lock nut of the dosage setting has during the fertilizing solved (Attention: tighten urgently with the appropriate tools!); thereby applying increased continuously (habs late realized that the amount decreased more slowly in Streuwagen towards the end and only after the Bowden then "plöpp" loosely hung down was also the cause clear).
Therefore, and wg. poor documentation of calibration / adjustment amount "only" 4 points.
