Troubleshooting Product Metering System

Symptom Problem Solution

Uneven/Inaccurate metering or product delivery.

Air leaking past lid seal.

Adjust lid closing down pressure.

Replace seal.

Product level too low for accurate metering.

Do not run tank empty; refill sooner.

In-tank pressure tubes (ladder rails), air control valves, or manifold end cap screens plugged.

Clean tubes, air valves, and screens.

Tank pressurization hoses plugged.

Clean hoses.

Half-width disconnect(s) closed or partially closed.

Completely open both disconnects.

Foreign material blocking product passages.

Remove blockage. Use screens when filling tanks.

Lumps in seed or fertilizer.

Use clean seed. Remove lumps from fertilizer. Use screens when filling tanks.

Reset agitator shaft action.

Meter segment rings not installed or wrong number installed.

Install correct number of fine tuning rings for secondary header ports.

Improper assembly of header ring or air system.

Reassemble correctly.

Symptom Problem Solution

No product delivery with clutches engaged.

Meter overload; drive pin sheared.

Replace sheared drive pin with 2.5 mm diameter cotter pin. See OPERATING MACHINE - PRODUCT METERING.

Engage meter only when fan is running to avoid overload.

Manifold slide in wrong position.

Position slide correctly.

Half-width disconnects closed, blocking product from meter.

Open half-width disconnects.

Symptom Problem Solution

Delivery rate above or below expected rate.

Tank not pressurized.

Adjust lid closing down pressure.

Check and replace lid seal.

Clean in-tank pressure tubes (ladder tubes), air control valves, and manifold end cap screens.

Clean tank pressurization hoses.

No enclosure doors installed.

Install doors on inactive runs.

Incorrect transmission speed setting.

Review rate chart and reset transmission.

Perform monitor calibration.

Check tire speed sensor gap and calibration.

Wrong meter segments for product in use.

Replace meter segments with correct segments for desired application rate.

Check transmission settings.

Check monitor set-up and calibration.

Inaccurate rate check results.

Rerun rate check.

Plugged product passages or meter segment flutes.

Check and remove caked product from passages and segments.

Wrong drive sprockets installed.

Change sprockets to agree with rear tire size and tillage row spacing.

Transmission crank turned in wrong direction during calibration.

Rerun rate check, turning crank counterclockwise.

Slide or manifold bypass openings plugged.

Clean openings.

Manifold slide in wrong position.

Position slide correctly.

Symptom Problem Solution

Half-width disconnects not fully open.

Move handles down to open product passages. Rerun rate check.

Variable rate not established.

Build rate selection menus. Perform variable rate set-up.

Manifold slide difficult to reposition.

Desired rates exceed capacity.

Reduce speed or add more primaries.

Foreign objects in slide path

Inspect for and remove foreign objects.

Material collects on slide.

Tap lightly on slide handle. Remove slide and coat with a PTFE or graphite lubricant.
