The Italian Backsaver Autospade

Tecnovanga is a special backsaver spade, made in Italy, that allows you to make less effort when spading.

manual spading

We are talking about a manual tool that serves to break up the soil of our garden and is produced in three versions:

garden spading fork
pointed spade
digging spade
Each of these models meets a special need for spading, that is, it is used for different types of soil.

The garden spading fork is the most popular model among gardening enthusiasts even though it is perhaps still little known compared to the more traditional garden spades models.

Tecnovanga garden spading fork is the model that allows you to till even heavy clay soil, making the tines penetrate into the earth and allowing you to lift even large clods with the least effort. In addition, the fork model is basically a wild card, because, despite being quite heavy, it can also be used to distribute fertilizer and bury it in a more uniform way, compared to other models.

And that's not all: the garden spading fork patented by Valmas also makes it easy to dig up potatoes by bringing out the tubers on the surface thanks to its four steel tines.

A patented spade for less effort

Cultivating a vegetable garden is one of the most rewarding hobbies, but those who engage in this activity know that it is also quite a chore.

Digging the vegetable garden by hand can be a passion as well as a necessity. Very often, for the size of the plot, it is not worth investing hundreds or thousands of Dollars for a motor-cultivator.

Secondly, with a manual spade it is easier to till the soil even in places where a walking tractor could hardly reach.

Last but not least: a motor-cultivator on a compact soil has anyway a complicated life: it is difficult to penetrate into the ground (not being a plough) if the clods have not been lifted manually before, at which point it will be easy for the motor-cultivator to break them up.

Digging the soil, in short, is an activity that stresses all the muscles, especially those of the back, and therefore should be carried out several times to avoid muscle strains and spinal pains that force us to bed.

Hence the need to reinvent the spade, a tool used for millennia and that for millennia has remained essentially unchanged, with its metal part that is driven into the ground and its wooden handle that acts as a lever and is used to lift and overturn the clods.

It is precisely on the lever effect that the functionality of the spade is concentrated and it is always the lever effect that goes to stress the muscles of the back.

How the Tecnovanga works

So what's so special about this spade? How does it relieve the burden of digging?

That's easy to say: at the junction between the shield-shaped blade (or fork, depending on the model) and the handle, a mobile mechanic has been inserted, a toothed gear that allows the handle to be inclined at a certain angle and then locked again.

Rather complicated to explain but much easier to see.

Basically: the spade is driven into the ground like any other spade, at which point you unlock the toothed gear and move the handle forward and then lock the mechanism again.

Now the leverage of the spade is significantly increased and just pull the handle towards us, with little effort, to tear the clod of earth.

Of course, to make the work smooth it is necessary to take the hand in such a way as to make the gesture increasingly mechanical and almost automatic, but once you understand the mechanism spade becomes much easier.

This does not mean that this special garden spade allows you to work without any effort, the clods once removed must still be turned over and their weight passes through our back.

At this point you might say, "eh, but then it's not worth it!".

The point is that spading by hand always costs effort, whatever tool you use, the advantage of Tecnovanga is to make this work less heavy.

This is because the effort, during digging, is not so much concentrated on the overturning of the clods but rather on the first phase, the part in which the clods must be "torn" from the ground.

It is in this phase that the toothed mechanism intervenes, allowing to increase the lever of the spade making a smaller effort.

In short, the advantages of this back saving spade are many but I want to point out one disadvantage as well: the weight.

This is a disadvantage on one hand but it is also a positive on the other.

Why do I say this?

Well, certainly the toothed gear has introduced additional weight to what would be the weight of a standard good quality spade. This is a disadvantage.

However, this disadvantage is also a virtue because it means that no expense was spared on the tool's sturdiness.

This is a fundamental point: the spade is a manual tool subject to very intense stress, both as regards the blade and the handle.

The weight, therefore, is justified by the good quality of the materials which, even more so with the inclusion of a mobile part, must withstand intense stress without breaking in a short time, something that none of us would want, right?
