Mounted Trio

The Mounted Trio has gained the reputation as the UK’s number 1 one-pass stubble cultivator. As the name suggests, the Trio comprises of three parts, each of these finely tuned to create a seedbed from stubble in one pass, an objective achieved by the vast majority of users.

Initial cultivations, to a depth of 400mm, is by shearpin-protected or auto-reset ultra-low draught subsoiler legs with carbide-tipped Concord quick-change points mounted in a staggered pattern on a heavy-duty toolbar with a 350mm forward stagger.

These are followed by a double row of 500mm diameter concave cultivating and mixing discs mounted in pairs on independently suspended arms in a dedicated frame, the finished seedbed created by a patented Multipacka: a 509 x 10mm barrel with shouldered rings and drive lugs provides a total diameter of 760mm. Tried and tested ring shoulders have a convex shape next to the barrel, creating consolidation and cracking even on top of the ridge.

Versatility is also a feature of the Trio. The disc frame is fully removable, allowing the Trio to be used as a subsoiler with low disturbance: ideal for sowing oilseed rape in one pass. Where the Trio is used to establish oilseed rape in a single pass, a further boost in efficiency is achieved through the fitting, alongside the standard point, of the LD point, which is designed to alleviate compaction while creating minimum surface disturbance, reducing the possibility of rogue weed seeds chitting.

Not only does the Sumo Trio contribute to reduced establishment costs and greater overall profitability through the use of less fuel to establish the crop, it also has a beneficial environmental impact; a vast reduction in the carbon footprint due to the double benefit of low diesel consumption and less carbon dioxide release from not inverting the soil. One Trio used in place of a plough on 200ha over one year would offset the whole of the CO2 produced in the Sumo factory in three years.

I was completely blown away when I saw a neighbouring farmer using a Sumo machine. We were so impressed we bought our own Sumo Trio back in 2007, and feel that it’s revolutionised cultivations for us at across our 1200 acres of arable ground. In fact, no other machine comes close. It’s set an incredibly high benchmark against which we will measure any other machinery that we consider using.
