Tine Drills | The Inverted T-Slot
Tine seed drills have a strong reputation among farmers for their versatility, reliability, and durability—making them a trusted solution across a wide range of farming conditions.
With a lower upfront cost and reduced maintenance compared to disc drills—without compromising on performance—our Tine Drills are a smart, economical choice for any operation.
The shoe pushes aside all surface trash and prunes the roots of the existing sward when rejuvenating grassland. The chamber allows light and moisture to penetrate but retains the warmth. Because the seed is surrounded by a fine tilth, root establishment is rapid.
Whether you’re working in cultivated soil, direct drilling into virgin ground, renovating existing pasture, or sowing into standing crops, Aitchison Tine Drills deliver consistent results, season after season.
Baker Boot – Inverted T-Slot with Coil Tine
The proven Baker Boot inverted T-slot opener is engineered to optimise seed placement and create ideal soil conditions for germination and plant establishment. The unique T-shaped chamber forms a microclimate that retains moisture and warmth, allows light penetration, and ensures excellent soil-to-seed contact—promoting rapid, even germination. This boot is replaceable.
The boot and tine combination perform multiple roles in one pass. It clears surface vegetation, dethatches existing pasture, and places seed firmly at the base of the T-slot via the integrated seed tube—delivering consistent, accurate placement.
Our coil tines, made from high-tensile 25mm spring steel, are designed for strength and durability. They reduce lateral movement to maintain a straight and accurate path through the soil, while their staggered layout and left/right-hand coil pattern help facilitate efficient trash flow.
Together, the Baker Boot tip and coil tine provide precise seed placement with minimal soil disturbance, ensuring optimal seed-to-soil contact for superior germination across a wide range of soil types and conditions.
Tines with Disc Coulters — Clean Entry, Consistent Depth
Disc Coulters play a vital role in maintaining seeding accuracy, especially in residue-heavy conditions. Mounted at the front of the seed drill, these discs slice through surface trash, creating a clean path for the tines to follow. This reduces trash buildup, improves soil entry, and ensures more consistent seed depth and placement—key factors for even germination.
All Aitchison Disc Coulters are spring-loaded, allowing them to deflect over obstacles while maintaining constant down pressure for reliable ground engagement.
Depth adjustment is simple and flexible, available via manual mechanical settings or optional on-the-go hydraulic control, giving operators the ability to adjust from the cab for changing field conditions. The combination of disc coulters and tines results in improved seedbed preparation, more accurate sowing, and better overall crop establishment.
Disc Drills | The C-Slot
Disc seed drills are the go-to choice for farmers working in rocky, compacted, or residue-heavy soils where tine drills may struggle.
With minimal soil disturbance and precise placement, they deliver clean, consistent results—especially in challenging conditions like Kikuyu pasture or hard summer ground.
The Disc system slices through surface residue to avoid hair-pinning, pushes aside/rides over stones and penetrates harder ground, and cuts a narrow furrow for accurate seed placement and moisture retention.
Ideal for direct drilling into existing swards or trash-covered paddocks, Aitchison Disc Drills deliver consistent seed depth and placement across all terrain types.
Heavy Duty Concave Discs
Each model is fitted with a heavy-duty concave single disc opener that’s staggered for efficient trash flow (350mm/14” on GrassFarmer® models, and 406mm/16” on Seedmatic® models). These units retain moisture, protect soil structure, and enable faster ground speeds—making them a smart choice for conservation farming or variable conditions.
Disc depth is easily adjustable via mechanical or optional hydraulic control, giving operators flexibility to adapt on the go. Low maintenance and highly effective, Aitchison disc drills are built to perform season after season.
