Single Pivot Point Link
As the row-unit encounters changes in the topography or in the stubble volume above the ground, it causes the whole unit to rotate around the pivot point, up and down. With these movements, the seed drop point and the angle of attack of the colter change affecting the way they cut the residues and also the penetration into the ground.
Parallel-Link Row Unit Design
It’s at the heart of our row-unit.
What makes this row unit special are these two arms that form our parallel link assembly, providing a lot more consistent performance out of the row-unit.
Our parallel link design row unit really is what provides the accuracy, versatility, and productivity that they’re famous for.
The THEYCO 2023 row-unit will guarantee a uniform emergence, increasing the chances of higher yields.
Upgrade Your Planter For No-Till Farming
The row-unit is attached to the frame by means of a parallelogram that allows to the shoe remain perpendicular to the ground at all times, therefore, always works with the same attack angle, keeping the relative depths between the seeds and the fertilizer constant regardless of the soil is not even.
The set of the 17 3/4″ disc and the shoe, allow for cutting the stubble and opening a uniform groove for the grains and the fertilizer.
This row-unit has exceeded all our expectations and will surely exceed yours as well.

Gauge Wheel Cleaning System
In the photograph, you can clearly see the problems caused by the conjunction of stubble and sticky soils with high humidity.
To solve this problem, initially, the gauge wheel had a conical boron steel extension on its inner face, which acted as a scraper on the surface of the sowing disc, removing stubble and mud.
The new wheel model reproduces the same profile of the gauge wheel with the conical rim with the boron steel conical rim but made entirely of urethane, achieving the same effect but tripling the useful life of the assembly.
To avoid the gauge wheel blocking, an open 3-spoke rim has been placed that allows the exit of stubble and mud that could be introduced between the disc and the wheel.
The hub now has a MAINTENANCE-FREE KRRS double-shielded double-row ball bearing.
Shoe And Discharge Tubes
The THEYCO 2023 row-unit allows for two possible configurations, seeds only or seeds, and fertilizer.
This alternative is optional, at the request of the client.
Plastic seed firmer
Plastic seed firmer: It has an adjustable plastic spring and two fastening screws that are screwed directly to the shoe.
Reduce maintenance time and costs.
The play of the shoe is increased with the passage of the hectares worked, varying the depth where the seeds are placed, affecting the emergence.
The new locking system of the shoe bolt prevents it from moving, thus avoiding the wear of the pivot point on the main arm.
For direct seeding, the pressure must be no less than 175 kg.
