One more time, we have a tool in our "Test on field" section. On this occasion, the mentioned tool is the Ovlac Minivid short disc harrow (from a Spanish manufactured called Ovlac). As we commented last year when we could work with Pöttinger Terradisc disc harrow, it is one of our favorite implement. The high working speed and perfect work done (independent of the height of the vegetation on the ground) and the aggressive angle of attack of its notched discs are features that convert this implement in a very attractive help for viticulture.
The Ovlac Minivid used by us has 2.15m working width (the working width can be varied hydraulically when you work with Minivid PRO model so it can work on lanes with a width difference of up to 50cm) and 16 discs using independent tines in high quality steel and 40mm rubber stone protection which is 100% maintenance-free. The working principle is the front row expels the soil to the outside (which is stopped by the side plates), while the back row, which is wider than the front, does it into towards the center of the machine. The roller then, levels, crumbles and consolidates the resulting surgace. A central arm, adjustable in height and fitted with a sweep share, does the job of the middle band which is left by the unmatched position of the front and rear rows of discs.
If we have to comment some problems, they could be its weight (it is important if you have to drive a lot of kilometers) and another problem could be you can't work very near grape vine as you can work using a special vineyard cultivator. We would like to test the new Ovlac Minichisel Vineyard; in a future post we’ll compare it with Minivid disc harrow... Definitely, the Minichisel Vineyard will be a fantastic tool for so many winegrowers.
Finally, in our opinion, we tested a good tool that is really perfectly manufactured (like Ovlac manufacture all its tools), it is made with high quality steel so it is ideal for some certain tasks because it allows us to work at high speed and save time and fuel.
