Factory Acceptance Checks for a 4-Row Precision Corn and Soybean Planter
How buyers can turn a factory acceptance test into pass or fail checks for a 4-row precision planter, using reference values such as 500–700 mm row spacing and 330 kg overall weight.
A buyer should decide before the factory acceptance test which checks are pass or fail, not merely observed, so a 4-row precision corn and soybean planter is accepted against agreed criteria rather than a visual walkaround.
Start with configuration: confirm the delivered unit matches the ordered row spacing within the 500–700 mm reference range and that the 4 rows are identified and measured individually. Ask the supplier to state the acceptance tolerance for each row and how it is measured. For a 30 hp matching tractor, agree how the planter is driven during the test and whether the demonstration uses representative seed.
For planting checks, define pass or fail for seed singulation, row-to-row consistency, and seed placement at a stated test speed. Ask whether the test covers corn and soybean separately, since seed size and shape differ. Weigh or verify the 330 kg overall weight as a reference value and confirm it suits the buyer's tractor and transport arrangements.
Before requesting a quote, confirm with the supplier which checks are included in the factory acceptance test, the tolerances and test conditions, who witnesses and signs the results, and what happens if a check fails.
