Single Pivot Point Link

When the seeding train encounters variations in topography or differences in the volume of fallow on the ground, it causes the entire mechanism to oscillate around a pivot point, moving up and down. These movements constantly alter the point at which the seeds are deposited as well as the cutting angle of the disc, which affects the efficiency with which it cuts through residues and its penetration ability into the soil.

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.

Llanta con rayos

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 client request.

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.
