Between one vine row and the next there is room to walk through, not to drive a tractor. The soil is compacted after winter, often on a terraced slope, and the usual machine either won't fit or would slip as soon as it's under load. This is the situation in most Italian hillside vineyards, where inter-row tillage is still done by hand — or skipped entirely.
What a rotary harrow does and what it doesn't
A rotary harrow breaks up clods, levels the surface, and prepares a uniform seedbed. The rear roller lets you set the working depth and lightly re-firms the soil after each pass. Without a roller, the profile is more aggressive and works best on already-loose soil or where re-firming isn't needed.
A rotary harrow does not replace deep tillage: it won't break up a hardpan, won't uproot dense vegetation, and won't shred vine canes of significant diameter. For that last job, which comes up often in vineyards, the right tool is a different attachment — as we explain in the article on professional vine cane shredders: how to choose.
The challenge of access in narrow inter-rows
A compact tracked carrier fits where a tractor cannot. The tracks spread the load across the soil and hold the gradient of terraced slopes without the machine sliding sideways while the attachment is working. The operator walks behind or to the side, clear of the vine row, and guides the machine without treading on the plants.
On a steeply terraced slope, a wheeled machine loses traction precisely when the harrow meets resistance. A tracked machine keeps contact with the ground on both sides and doesn't need added ballast to stay in place during the job.
How to mount the harrow on the tool plate
The tool plate is a standardized quick-attach system: the harrow locks mechanically onto the plate and connects to the machine's power take-off. The whole operation is done at the jobsite, with no trip back to the shop and no special tools. When the harrow isn't needed, it unlatches and any other attachment — blade, bucket, tiller — goes on with the same identical mount.
The requirement is that the machine comes with the tool-plate version. Not all tracked carriers have it: it is a specific configuration that must be selected at the time of purchase.
In the Cormidi lineup
The CMF multi-purpose machines come with the tool plate in the SP2 and SP3 versions. The rotary harrow, with or without roller, is one of the attachments available for that plate. The same machine can switch attachments in the field and move, for example, from soil tillage to hauling the collected material with the tipping skip.
The CMF machines are available with gasoline or diesel engines, with an operator platform, and in remote-control versions for those working on gradients where walking alongside the machine is not practical.
What to check before you choose
Measure the usable width of your inter-row at its narrowest point, accounting for the canes. Check whether your soil has a gradient that calls for tracks, or whether a wheeled machine is enough. Determine whether you need a single attachment or several interchangeable ones: if the answer is several, a carrier with a tool plate earns its keep all year, not just in spring.
To compare options for the right machine for your vineyard, talk to your local Cormidi dealer: they know the local conditions and can point you to the right configuration.
