Assembled Coulter Disc Picks - Complete Units and Individual Discs for Planters of Different Brands

A coulter disc is one of the most important components of a planter row unit. It directly affects depth stability, residue cutting, furrow formation, and - ultimately - uniform emergence. In real farm conditions, operators usually face two different maintenance scenarios: either you must get the machine back into the field fast with minimal downtime, or you service the planter proactively by replacing only the parts that are genuinely worn.

At BAS-Agro, you can buy:

• individual coulter discs for planters from different brands;
• an assembled coulter disc unit (disc + hub/bearing assembly) - also for different brands, when fast replacement and predictable performance matter.

This article provides a compact selection of popular assembled coulter disc units from the bas.ua catalog, plus practical guidance on when an assembled unit is the smarter choice and when an individual disc is enough.

Individual Disc vs Assembled Unit: How to Choose

Buying the disc only makes sense when the hub and bearings are still in good condition: no play, no noise, seals are intact, and the goal is to restore cutting geometry and working diameter. This is cost-effective for scheduled maintenance, when you have time to inspect each row unit and you want to avoid replacing components that still have solid service life left.

Buying a disc in assembly is the right move when:

• there is play or bearing noise, noticeable heat, grease leakage, or damaged seals;
• you need to minimize repair time, especially during peak field windows;
• you want a predictable outcome with no “weak link” left inside the unit, because a worn bearing can destroy a new disc prematurely.

In simple terms, an assembled unit often wins because it reduces the risk of having to redo the repair mid-season. A standalone disc is the economical option when the rest of the assembly is verified to be healthy and your service process is under control.

What to Check When Selecting Coulter Discs

Selecting “by brand” is only the first step. To ensure correct fit and stable performance, you should verify technical parameters and compatibility.

Key criteria:

1. Disc diameter (for example, 300 / 350 / 373 / 380 mm) - affects cutting aggressiveness, depth behavior, and row unit setup.
2. Solution type (disc only or assembled unit) - defines the scope of work and service approach.
3. Compatibility with your planter/row unit - even within the same brand, different generations and configurations can vary.
4. Part number - the most reliable way to avoid mistakes, especially if your fleet includes multiple planter models.

Practical tip: if you are unsure about bearing condition, play, or sealing - in most cases it is cheaper and faster to close the issue with an assembled unit than to come back for a second repair during planting.

Why “Assembled” Is Often the Pre-Season Choice

During planting windows, downtime is not only a repair cost - it can also mean missing optimal soil moisture and temperature conditions. That is why assembled coulter disc units are often purchased as a “season insurance” solution or as the fastest way to restore a row unit.

Main benefits of an assembled unit:

• fast replacement without extra bearing, seal, or hub sourcing;
• predictable service life when old bearings are already near end-of-life and can ruin a new disc;
• fewer assembly errors, especially when service happens in the field.

At the same time, if your maintenance routine is strong and you can inspect hubs and bearings properly, buying individual discs can still be a rational strategy. BAS-Agro supports both approaches - you can purchase discs only or complete assembled units depending on your service plan.

Where to Buy Coulter Discs for Different Planter Brands

You can check availability and select the right option - disc only or assembled coulter disc unit - at BAS-Agro: https://bas.ua

If you are ordering for a specific planter model, use disc diameter and part number as your main reference points. This is the fastest way to avoid mismatch and ensure the part installs correctly and delivers stable performance throughout the season.
