Sprocket Blocks for Seed Drills: BAS-Agro (bas.ua) Manufactures Parts for Kverneland, Monosem, KUHN

A seed drill is one of those machines where mechanical precision directly becomes seeding precision. One component that often stays “behind the scenes” but has a real impact on consistent operation is the sprocket block (chain wheel block) in the drive system of the metering units and related mechanisms. This assembly transfers torque through the chain drive, maintains correct pitch engagement, and keeps key units rotating in sync - which affects seeding rate and emergence uniformity.

BAS-Agro LLC (Cherkasy, Ukraine) manufactures and supplies agricultural machinery parts, including sprocket blocks for seed drills of different brands. You can order ready-made items via bas.ua, and you can also request manufacturing by drawing or by sample.

Why sprocket blocks are a critical wear part in a seed drill

A sprocket block operates under constant load, dust, moisture, and vibration. Common reasons for replacement include:

worn teeth (the chain starts “eating” the sprocket);
play, misalignment, or runout (the chain runs unevenly, accelerating wear of other parts);
damage after jamming or foreign objects entering the drive;
the need to change drive ratios (to match a different seeding rate or configuration).

In practice, timely sprocket block replacement is often cheaper than repairing the whole chain-drive “cascade” - chains, tensioners, shafts, bearings, and mounting seats.

Quick overview of KUHN, Kverneland, and Monosem seed drills: what owners should know

Kverneland: versatile solutions - from grain drilling to precision planting

Kverneland offers a broad range of equipment - from general-purpose grain seed drills and combination units (seedbed preparation + seeding in one pass) to precision seeding solutions for different crops. In these machines, drive accuracy matters, especially when working at different speeds and in variable field conditions.

KUHN: seed drills designed for different tillage systems

KUHN’s lineup includes solutions positioned as versatile for operation after ploughing, under minimum tillage, or even with higher residue levels. In real farming conditions, that versatility often means the drivetrain sees changing loads - and sprockets and chain components take the hit first if anything is worn or misaligned.

Monosem: precision seeding and stable drive kinematics

Monosem is widely associated with precision planters, where consistent seed placement and closing performance are essential for uniform emergence. In precision seeding, there are no “small” details: if the sprockets and chain run inconsistently, it can lead to surging, skips, or uneven seed spacing - especially at higher operating speeds or with worn drive parts.

Manufacturing to your requirements: by drawing or by sample

Beyond catalog items, BAS-Agro supports custom orders: you can provide a sample part or a technical drawing, agree on terms, and manufacture an identical replacement part or a batch. This is especially useful when:

you need a part urgently and original supply lead times are too long;
the machine has a non-standard configuration;
you’re restoring a unit based on real operating conditions (after upgrades or repairs).

How to order a sprocket block
