Before You Drop the First Seed: A Pre-Season Planter Checklist for Western Kansas Corn Growers
Planting season for corn growers in Western Kansas requires all hands on deck. With such a narrow window for planting, there’s no room for your equipment to have a breakdown before you reach real progress. The best way to prevent costly downtime and defend yourself from in-field surprises is to perform a thorough planter inspection before your tractor even leaves the shed. American Implement's parts and service teams are here to support you across every stage of the season, but this checklist will walk you through exactly what to look for before you decide to schedule an appointment or order parts for a repair.
Start With A Deep Clean
A thorough cleaning before inspection gives you a clear view of what's at stake and reveals problems that would otherwise stay hidden under a season's worth of dust, fertilizer residue, and crop debris.
Clear Out Seed Components First
Crop debris and dust from last season can clog seed tubes and disrupt singulation accuracy before you plant a single row. Blow out your seed tubes, seed tube guards, seed meters, and meter housings with compressed air to clear any buildup. Pay special attention to meter housings; even fine dust accumulation can affect seed disc rotation and finger pickup performance.
Pressure Wash the Frame and Row Units
Remove all soil, fertilizer buildup, and organic matter from the entire planter frame. Fertilizer residue is especially corrosive. After washing, inspect painted and bare metal surfaces for rust or pitting, particularly on the toolbar and row unit shanks. Let the planter fully dry before moving into detailed component inspection. Wet components mask wear and make it harder to accurately assess disc edges, gauge wheel contact, and parallel linkage movement.
Check Every Tire
Inspect transport tires for proper inflation and sidewall cracking. Check the press and closing wheel tires for cracking, dry rot, or uneven wear that could affect seed furrow closure. A flat during planting season is an inconvenience you don’t want to have.
Row Unit Inspection
Row units take more abuse than anything else on your planter. Each one is responsible for opening the furrow, placing the seed, and closing behind it. Wear in any one of those systems costs you in the long run.
Replace Worn Disc Openers
Measure disc diameter and replace any disc worn below the manufacturer's minimum. Undersized discs can't hold consistent furrow depth. Spin each disc by hand and check the bearings for roughness, play, or noise. A bad bearing causes wobble, which means inconsistent furrow width and erratic seed placement.
Verify Gauge Wheel Condition and Adjustment
Inspect gauge wheel rubber for cracking, chunking, or flat spots. Worn gauge wheels can't maintain consistent disc contact, and that directly affects depth control. Check arm bushings and pivot points for wear and slop — excessive play translates to furrow depth inconsistency across the field. Confirm gauge wheel adjustments are uniform across all row units, because depth variance between rows shows up as uneven emergence and lost yield.
Inspect Seed Tubes and Guards
Check the interior surface of each seed tube for wear grooves or gouges. Worn tubes let seeds tumble or ricochet on the way down, increasing spacing variability. Replace any tube where the surface is visibly grooved or where seeds don't fall cleanly during a bench drop test. Inspect guards for cracks or missing material. If your planter has seed tube sensors, check each one for debris or damage. A faulty sensor generates false misses or skips and corrupts your monitor data all season.
Test Closing Wheel Pressure and Wear
Inspect the rubber or cast-iron contact surface on each closing wheel for wear. A closing wheel that can't pinch the furrow closed leaves seeds in an air pocket, which prevents germination. Check arm tension and spring pressure; inadequate down pressure is a common cause of poor seed-to-soil contact, especially in western Kansas soils. Inspect closing wheel bearings for roughness or play while you're there.
Check Parallel Linkage for Play and Damage
Inspect all four parallel linkage arms on each row unit for cracks, bends, or deformation. Damaged arms prevent the row unit from floating independently, and you lose consistent ground contact. Check all linkage bushings for wear by grabbing the row unit and pushing and pulling it side to side. More than a small amount of play means the bushings need to be replaced.
Meter & Delivery System
Your planter's entire job is to place one seed at a precise interval, every time. The meter and delivery system is where that happens, and it deserves close attention.
Disassemble and Inspect Seed Meters
Remove and disassemble every meter housing. Inspect the housing interior for wear, cracking, or debris that could interfere with disc or finger movement. Check brushes, wiper seals, and spring-loaded components for wear and replace anything that doesn't move freely.
Match Seed Discs to Your Seed Lot
Cell size matters. Using the wrong disc for your seed size is one of the fastest ways to hurt singulation. Inspect each seed disc for worn, cracked, or deformed cells. Worn cells allow doubles or produce skips. Check the fit between the disc and the meter housing and confirm there's no wobble or side play.
Calibrate the Drive System Before the First Pass
Inspect the planter's primary drive for proper function.
- Ground-drive systems: Check drive chains and sprockets for wear, stretch, and proper tension. A worn chain skips teeth under load, which means missed seeds and erratic spacing.
- Electric drive systems (e.g., John Deere ExactEmerge or SeedStar XP): Check harness connections for corrosion, damage, or loose pins at each row unit, and confirm motor mounting hardware is tight.
Before your first field pass, run a seed count test at a known distance and compare the actual count to your monitor's reported population. Don’t wait to calibrate when in the field; do it now.
Hydraulics
Most modern planters rely on hydraulics for lift, down pressure, markers, and in some cases drive systems. A hydraulic failure at planting is a full stop.
Check all hydraulic hoses along the length of the planter for cracking, abrasion wear, kinking, or fitting damage. Pay particular attention to hoses that cross fold points or run near moving components. Inspect couplers and fittings for leaks, contamination, or wear; contaminated hydraulic fluid is a leading cause of valve and cylinder damage. Cycle the planter through its full range of functions — lift, lower, fold, marker deploy — and watch for slow response, drift, or unusual sounds. Don't skip the marker arms and cylinders; they're frequently overlooked during pre-season checks and are a common source of in-season leaks.
Precision Ag Tech
Your technology is only as reliable as your connections and calibrations.
Confirm Your Planter Monitor Is Ready
Power up your planter monitor — whether that's John Deere GreenStar, SeedStar XP, or a third-party system — and confirm it's communicating with all row unit sensors before you leave the shed. Check for software and firmware updates at the start of the season; updates frequently include bug fixes and improved sensor compatibility. Contact your American Implement precision ag team for guidance on updates specific to your setup.
Inspect Row Unit Sensors and Harnesses for Damage
Check seed sensor harnesses at each row unit for rodent damage, abrasion, or pulled connectors. Planters stored in sheds over winter are a regular target for mice, and a chewed harness won't surface until your monitor starts throwing alarms mid-planting. Clean sensor faces with compressed air, check for physical damage, and run a full planter diagnostic from the cab to confirm all row units are reporting correctly before you enter the first field.
