- This part of ISO 7256 specifies a test method for seed drills for sowing in lines, including seed drills attached to a basic machine. The test method permits the determination of performance using reproducible tests so that comparable results in numerical or graphical form which take into account the influence of the following can be obtained: — type of seed; — the forward speed; — the level of seed in the hopper; — the application rate adjustment; — the slope of the ground; — the condition of the soil surface (bumps). Optional tests (see annex B) may supplement the test method by taking into account the effects of products used for treat-ment and distribution on the sowing site. The mandatory tests do not give any picture of the true distribution of the seeds on the sowing site. NOTE - Part 1 of ISO 7256 deals with single seed drills (precision drills). (See ISO 3339/0 for the classification.)
