Actual seeding rate
is different than
desired If not already performed, calibrate.
Check marker extension (page 25). If too short, overlap results in over-seeding. If too long,
gaps result in under-seeding.
Check tire sizes and pressures, listed at “Tire Inflation Chart” on page 114.
Check for build-up of seed treatment in seed cup. Disassemble cups and scrape off any build-
up.
Check seed-rate setting. Seeding rates will vary with seed weight and size. See “Material
Rate Adjustments” starting on page 74.
Excessive seed
cracking Use a faster drive type and a lower seed-rate-handle setting.
Position seed-cup handles to a lower notch (higher number).
Monitor does not
measure accurately Check tire sizes and pressures against “Tire Inflation Chart” on page 114.
Check seeding operation for excessive overlap or gaps between passes.
Consider soil conditions–loose soil and slippage will cause variations in acres registered.
Recalilbrate monitor.
Uneven seeding
depth Check that openers have sufficient down pressure. See “Opener Down-Pressure” on
page 73.
Press wheel not
compacting soil as
desired Reset press-wheel depth. See “Opener Depth (Press Wheel Height)” on page 93.
Increase down pressure on openers. See “Opener Down-Pressure” on page 73.
Press wheels or
openers plugging Consider field conditions. Drilling in damp or wet conditions may increase this problem.
Reduce down pressure on openers. See “Opener Down-Pressure” on page 73.
Do not back up or stop and allow drill to roll back with openers in ground.
Check optional Seed-Lok wheels.
Seed-cup sprockets
locked up or twisted
seed-cup shaft Check for foreign material lodged in seed-cup sprocket.
Look for dried liquid insecticide in seed cups. Remove build-up by disassembling each cup and
scraping turning surfaces.
Chain-Debris/
retainer clip Be sure retainer clip open end is facing the opposite way of chain travel.
