Coil & Spring Tyne Undercarriages

425 Coil Tyne

The Agrowdrill 425 coil tyne has been a mainstay of our seed drills for years – and with good reason! The robust design ensures the tyne has the strength to last season after season for sowing in wet, dry, or high-trash conditions.. The inverted-T shape of the Baker Boot point opens a groove in the soil designed to minimise soil disturbance and ensure effective seed placement.

The 425 coil tyne has a maximum breakout of 136kg (300lbs), an underframe clearance of 620mm, and is available as an undercarriage option on the AD083, AD140, and AD240 seed drills.

251 Spring Tyne

The 251 Spring Tyne offers users a robust solution to meet the needs of large-scale direct drilling.

The Baker Boot point creates a soil micro-climate ideal for seed germination and maximising crop potential. It has the strength to handle seeding in a variety of conditions whilst maintaining the accuracy and reliability that Agrowdrills are renowned for.

The 251 Spring Tyne has a maximum breakout of 114kg (251lbs), an underframe clearance of 620mm, and has been designed for the AD730.

552 HD Spring Tyne

This is a heavy-duty tyne for the AD730 Agrowdrill, with a breakout of more than double the 251 tyne, and a higher underframe clearance of 750mm.

Featuring toughened tungsten-hardfaced wedge points, the 552 HD Spring Tyne's sturdy construction makes it capable of drilling deeper for longer through the toughest terrain, including sandy, hard, and dry soil conditions.

The 552 HD Spring Tyne has a large breakout of 250kg (550lbs) and is exclusive to the AD730.

Double Disc & Ground Following Undercarriages

401 Double Disc

The 401 Double Disc is ideal for zero-tillage sowing applications. It comes with a matched pair of plain and notched discs that open a narrow funnel for the seed whilst ensuring maximum trash flow. The spacing between the discs can be modified with optional spacers to better suit a range of soil conditions. The self-cleaning design breaks through stubble and trash to create a clean soil furrow with minimal soil disturbance.

The 401 Double Disc Unit has a downforce of 205kg (2010N), an underframe clearance of 620mm, and is an available undercarriage option for the AD083, AD140, and AD730 seed drills.

Ground Following Parallelogram

Heavy-duty ground-following double-disc unit with built-in presswheel mounted on a parallelogram undercarriage.

This advanced design delivers consistent and optimal seeding angles over any terrain for more consistent sowing and seed placement and comes with the robust and reliable build quality and performance you expect from Agrowplow. With the optional hydraulically controlled coulter bar, the AD340 becomes a full triple-disc seeder, enabling the machine to sow in practically any soil conditions or no-till operations.

425 Baker Boot with Hardfacing

Baker Boot Points

Agrowplow's baker boot points are fabricated and not cast, being made in Australia out of 6 mm Bisalloy wear-resistant plate. This premium heavy-duty build is more resistant from cracking or breaking, ensuring robustness when striking unseen objects hidden below the soil.

The baker boots are tungsten hardfaced on the leading edges to protect the wear surfaces and extend the working life of the point.

Agrowplow Baker Boots provide excellent seed-to-soil contact, minimal soil disturbance, accurate seed placement, and maintenance of soil structure, all of which contribute to improved seed germination and plant establishment.

Points are available in a variety of styles to suit different operation and soil types.

Double Discs

Agrowdrill double discs consist of a matched pair of 16" plain and notched discs that open a narrow funnel for the seed while ensuring maximum trash flow. The spacing between the discs can be modified with optional spacers to better suit a range of soils and conditions. Mud scraper units can also be fitted to better handle muddy conditions. 

The notched disc has ten notches and sits forward on the left-hand side of the assembly. The plain disc sits back on the right-hand side of the assembly. This offset design allows the discs to cut through trash for zero tillage applications in a range of soil conditions.
