As we move into late February, most of our territory is focused on getting ready for spring fieldwork, not winterization. This checklist is built for row-crop and mixed operations using Sunflower and Kuhn Krause field cultivators, vertical tillage tools, and disks to prepare seedbeds ahead of corn and soybeans.
Why Spring Tillage Prep Matters Now
Once the first warm, dry stretch hits in March or April, you only have a narrow window to size residue, level ruts, and build a consistent seedbed. A tillage tool that isn’t field-ready can cause streaky emergence, compaction, and extra trips across the field. Investing a few hours in the yard now helps avoid breakdowns 10 miles from the shop when every hour counts.
If you run Sunflower or Kuhn Krause primary or secondary tillage tools purchased through Parallel Ag, this is the perfect time to walk through a systematic inspection. Explore new and pre-owned equipment options here: Parallel Ag
Spring Tillage Equipment Prep Checklist
1. Frame, Tongue, and Hitch
- Walk the frame front to back for cracks, broken welds, or bent members, especially near previous repair sites.
- Inspect the tongue and clevis for elongation or cracks; ensure hitch pins and safety chains are correctly sized for your tractor class.
- Check folding mechanisms on larger Sunflower and Kuhn Krause tools for excessive play in hinge points or pins.
2. Shanks, Sweeps, Blades, and Points
- On Sunflower and Kuhn Krause field cultivators, measure sweep wear—most manufacturers recommend replacing when they’ve lost roughly 25–50% of original width for consistent depth and weed control.
- On disks and vertical tillage tools, inspect blades for:
- Cracks or chips at the edge
- Excessive diameter loss
- Loose or worn bearings
- Replace a few blades now rather than fighting failures in the field; mix new blades evenly across the gang to maintain level performance.
3. Depth Control and Leveling
Accurate depth is critical to avoid smearing wet soils or leaving seedbeds too rough.
- Check all depth control linkages, turnbuckles, and gauge wheel arms for wear or bent components.
- Set the tool on flat concrete and measure from the frame to the ground at key points to confirm it sits level side-to-side and front-to-back.
- Verify depth stops, spacers, or electronic depth systems are functioning and calibrated to your target working depth.
4. Bearings, hubs, and moving joints
- Tillage units rely on dozens of spinning and pivoting components.
- Spin each gang, coulter, and rolling basket by hand; feel and listen for rough bearings or play. Replace anything noisy or loose.
- Grease all zerks according to the operator’s manual, using high-quality grease compatible with your OEM spec.
- Check wheel hubs for oil/grease leaks and adjust bearings as needed; catch failures before they strand you on the road.
5. Tires, Wheels, and Transport Safety
- Inspect tires for stubble damage, sidewall cracks, and low tread, especially on tools that see a lot of road time.
- Set tire pressures to the recommended range—underinflation affects depth consistency and transport safety.
- Make sure all transport locks, safety chains, and SMV (slow-moving vehicle) emblems are in place and visible.
6. Hydraulics and Folding Systems
Hydraulics control depth, folding, and wing down-pressure on many modern Sunflower and Kuhn Krause tools.
- Inspect hoses for abrasion, cracks, or soft spots; replace any hose showing wire braid or blistering.
- Check couplers for leaks and ensure they connect cleanly to your tractor remotes.
- Cycle all hydraulic functions (fold/unfold, raise/lower) several times and watch for jerky motion or leaks around cylinders.
7. Finishing Tools and Residue Management
The goal is a level, firm, but not compacted seedbed.
- Check rolling baskets, harrows, and drag bars for bent tines or broken mounts.
- Confirm basket or harrow down-pressure adjustments work and that you can fine-tune them for different soils across Oklahoma, Kansas, and Missouri.
- Adjust gang angles or finishing attachments to handle heavy corn residue in Iowa and Minnesota versus lighter soils in the Texas Panhandle.
Use this checklist on your primary tillage tools (rippers, disks) and secondary tillage tools (field cultivators, vertical tillage) before they see the first acre.
Example Scenario: Marshall, Missouri Corn and Soybean Farm
Here’s a hypothetical example of how this checklist might look on a real operation. Imagine a 2,000-acre corn and soybean farm near Marshall, Missouri running a Sunflower field cultivator and a Kuhn Krause vertical tillage tool ahead of planting. The operator wants to avoid past issues like uneven emergence in river-bottom fields tied back to inconsistent tillage depth and worn sweeps on the outer wings. Using the checklist, their team would:
- Park each tool on flat concrete and check level in multiple spots.
- Replace worn sweeps and a handful of disk blades across the gangs.
- Tighten wing pivots and inspect folding hydraulics for leaks.
- Grease all zerks, check tire pressures, and confirm transport locks.

Integrating Tractors with Sunflower and Kuhn Krause Tools
The best Sunflower or Kuhn Krause tillage tool still underperforms behind the wrong tractor setup.
- Match tractor horsepower and ballast to the tool size to maintain target ground speed without excessive slip.
- Verify hydraulic flow and remotes are sufficient for folding, wing downforce, and any active depth systems.
- If you’re running guidance, use it to reduce overlap and compaction—accurate passes can save fuel and time on every tillage trip.
If your current tractor or tillage package struggles to pull consistently at depth, it may be time to look at a different size tool, different configuration, or an updated tractor. Explore tractors and compatible equipment here: Equipment Showroom.
When to Involve the Parallel Ag Service Team
Some issues are easy to spot in the yard but harder to fix correctly without the right tools and experience.
Consider scheduling service if:
- You see frame cracks or complex weld failures.
- Hydraulics are slow, uneven, or leaking internally.
- Electronic depth or leveling systems throw codes or won’t calibrate.
- Wheel bearings or hubs show repeated failure history.
Parallel Ag’s Service Department is set up for this kind of pre-season work, with mobile service and peak-season support. Learn more or request an appointment here: Service Department
FAQ: Spring Tillage Equipment Prep
When should I start spring tillage prep?
For most of Oklahoma, Texas, Kansas, Missouri, Illinois, Iowa, and Minnesota, late February through early March is ideal so your Sunflower and Kuhn Krause tools are ready before the first workable field days.
How often should I replace sweeps on my Sunflower or Kuhn Krause field cultivator?
Replace when they’ve lost roughly 25–50% of their original width or when you see streaking and inconsistent weed control behind the tool.
What ground speed should I run my secondary tillage at?
Most field cultivators and vertical tillage tools are designed for around 5–8 mph; check your operator’s manual and adjust based on soil type and residue conditions.
How do I know if my tillage tool is level?
Set it on flat ground, measure from the frame to ground at multiple points, and adjust hitch height, gauge wheels, and wing levelers until measurements are consistent across the tool.
Can Parallel Ag help with both parts and field checks for Sunflower and Kuhn Krause tools?
Yes—Parallel Ag locations across our seven states can supply OEM parts, inspect your tools in the shop, and help you prioritize repairs before planting.
Wrap-Up and Next Steps
Now is the time to walk around your Sunflower and Kuhn Krause tillage tools, not when the forecast finally gives you three dry days in a row. A simple, systematic spring tillage equipment prep checklist will help you hit that first field with confidence, protect your planting window, and set up better stands across your acres.
