The ground is compacted after winter, or just cleared of turf. The vineyard row is too narrow for any tractor. The backyard garden has a pedestrian gate as its only access. Before seeding or planting, that soil needs to be worked — and the problem is never the will to do it: it's getting there with the right attachment.
There are three attachments for soil preparation, and each one does something different. Using them in the wrong order means doing the work twice. Using all three with a single compact machine changes the whole workday.
The tiller: start here
The tiller works deep. The tines — or blades, depending on the model — break into the soil, chop it up, and turn it over. This is the first pass whenever the ground is hardened, compacted, or still bound by residue from the previous season. Without this step, everything that follows underperforms: a rotary harrow won't refine soil that's still hard, and a roller won't consolidate what hasn't been loosened first.
The tiller is also useful for incorporating low crop residue or opening up the soil along vineyard rows, where hand hoeing would take entire days. The limitation is that it leaves the soil disturbed and uneven: it's a starting point, not a finished result.
The rotary harrow: the second pass
After the tiller, the soil is loose but still coarse. The rotary harrow refines it. Rotors with vertical tines spin against the surface, breaking up larger clods, leveling the ground, and creating a uniform seedbed. This is the pass that turns worked soil into ready soil.
It's also available with an integrated rear roller: in that case the second and third passes happen at once, saving a full run. Where the soil is already fine enough after tilling, a harrow with roller lets you finish the prep in a single pass. Where the soil is heavy or very uneven, it's better to keep the passes separate.
The roller: closing out the job
The roller lightly consolidates the surface, breaks up remaining clods, and brings the soil into contact with seeds or transplant roots. It's not always necessary: on soil that's already fine and well worked, you can skip it. It becomes essential when the soil has stayed too loose after harrowing, or when broadcasting seed and you want uniform seed-to-soil contact.
In the vineyard, the roller also helps control erosion along sloped rows by consolidating the surface after the previous passes.
In the Cormidi lineup
These three attachments — tiller, rotary harrow with or without roller — mount on the tool-carrier plate of the CMF multi-purpose machines and the mini skid loaders. They attach and detach right on the jobsite without going back to the shop, so in a single outing you can till, harrow, and roll with one machine.
The CMF and CLX1500 are tracked: they fit through a pedestrian gate, work in narrow vineyard rows, and don't leave heavy ruts in soft ground. For anyone working gardens, yards, or vineyards where a tractor can't get in, that's the point that matters most.
Before choosing, what to check
Measure the narrowest passage the machine needs to get through — gate, gap between plants, field entrance — and compare it to the width of the tracked undercarriage. Check what type of soil you're dealing with: clay-heavy ground calls for a robust tiller, sandy and already loose soil may only need a harrow. Consider how many times a year you'll use these attachments, because that's what tells you whether it makes more sense to own the machine or rely on a contractor who's already set up.
To figure out which machine and attachment combination fits your specific situation, talk to a local Cormidi dealer: they know the soil in your area and can show you the machine under real working conditions.
