Seed Drills




Disc-O-Mulch   Maximulch

Disc-O-Mulch harrows feature two rows of cutaway discs for high speed and shallow cultivation for blackgrass control. The discs will also encourage weed and volunteer seeds to germinate or offer deeper cultivation for incorporating large amounts of residue, including maize stubble.

Disc-O-Mulch machines are available as mounted 3m to 4m rigid, 4m to 6m folding or 4.5m to 12m trailed.



Unique features include 3D disc mounting and heavy duty pigtail springs which attach each disc to the frame allowing the disc to move in 3 directions. This improves mixing and penetration, but at the same time reduces the power required compared to traditional systems. A patented board between the discs shatters clods and improves mixing. A wide choice of rollers is offered.


The Maximulch uses the same principles as the Disc-O-Mulch with two rows of scalloped or mulcher discs, but also incorporates a row of pan-busting tines with patented TCS blades. These raise the soil profile over the full working width to create vertical fissuring so improving aeration and drainage.

The tines are positioned between the two disc rows for best mixing action and reduced power requirement, saving fuel and therefore cost.

This machine is available with a choice of rollers to suit different conditions. A hydraulic folding option brings the weight of the packer closer to the tractor for roadwork.

The loosening tines are available with shear bolt or “non-stop” spring protection. Each disc is mounted on a maintenance-free hub for long life performance. An air seeder can be fitted for one-pass establishment of OSR, cover crops etc. Available as mounted 3m to 4m rigid or 4m to 6m trailed.
