We used to do this albeit with a discaerator rather than trio. Simba toptilth/Galucho Tilthmaster; cheap as chips to buy and run. Hugely underrated in my opinion. Other option would be short disc of some description but cost would go up. As others have said; just go a notch deeper than you think you need and it will come up fine.I am looking at moving from a system using a Trio followed by power harrow combi to a sabre tine, sometimes direct on to stubble and at other times following Trio cultivated land. My concern is that the cultivated land will not be level enough for the Sabre tine so a levelling cultivator will have to be used after the Trio. Any ideas on the best way to do this at low cost would be appreciated.
