What you need and how you choose to shred

For the recovery and maintenance of wooded green areas, the brushcutter is still the most widespread and used machine. Versatile and easy to handle, it adapts to all areas of use, due to the type of cut and the width of the surfaces to be worked. However, the price to pay is a considerable physical commitment on the part of the operator, especially when it comes to particularly dirty floors and/or large surfaces. However, there is also specific agricultural tools allowing this type of work to be carried out with less effort: shredders or forage harvesters .

There are many proposals for shredders on the market: both specific machines that only cut bushes and applications that connect to tractors, lawn mowers and tillers through the PTO.

Leaving aside the tractors, we will talk about the mulchers suitable for those working on a small to medium scale , so we stayed in an area with little agricultural mechanization. In this article we will see together when it suits you evaluate the purchase which aspects to evaluate and the main characteristics of a shredder.

How does the grinder work and when is it used

the grinders or shredders independent or to be applied to the drawbar, are accessories that are connected to the engine PTO, transferring the movement to a roller equipped with tilting blades (Y-shaped or “blades” for grass), these perform the actual cutting action.

Compared to the flat blades of conventional mowers, flail mowers are totally different in concept, function and performance. The structure of the brushcutter guarantees the possibility of cut and shred grass, brambles, young trees, fallen branches, reeds without difficulty . However, this is done to the detriment of the quality of the cut, which is generally less precise and more thick . The harvester is an appropriate tool for agriculture and certainly not for landscaping, where you work on a well-kept lawn.

So if you just want to mow the grass it’s best to use a mower deck, if you want to make hay with a cutter bar instead. The crusher is a machine that “attacks” uncultivated areas instead, cutting and crushing virtually anything: grass of any size, small woody shrubs, brambles. The flails of the machine grind quite finely what they find in their path, which is why the tool is also called a grinder. .

How to choose the grinder

Once it has been decided that a grinder is needed, the difficult moment of purchase arises. . It is not trivial to make a choice among the various proposals on the market and to understand which product suits us and adapted to the size of our land.

An important decision concerns the type of engine use : first of all, you need to decide whether to buy a separate mulcher or buy the mulching attachment that will be applied to the tiller.

Try before you buy

A good way to avoid wasting money unnecessarily, which I recommend to those who have no experience, is to borrow a chipper from an acquaintance and try it on your own land. You will find out with the use what are the dimensions that would be useful to us, the power required and the factors that make driving comfortable. If you don’t know anyone who owns this machine, you can also consider renting it .

walking tractor shredder

The purchase of a rotary cutter crusher requires above all to have a walking tractor , who makes the garden often uses this tool for tillage. In this case, having a mulcher to connect to the PTO (power take-off) of the tiller can be a good investment. In this case you only pay for the cutting material with its mechanics, but it saves on the engine, the traction system, using those of the tiller.

The important thing is to assess before buying whether the conformation of the earth treat allows us to use this means. Grounds full of holes, very sloping, full of obstacles do not allow the effective use of a rototiller mulcher: one would have to maneuver continuously (and with fatigue) proceeding very slowly.

If the ground is mostly flat, as long as your tiller has an unlockable differential, steering won’t take much effort. As soon as the work on a slope or uneven ground it would be desirable, if not necessary, to have a machine with independent brakes on both wheels. Ideally it should also have independent clutches, which is not a common feature and usually only found on some special machines or self-propelled mulchers.

Drawbar requirements

As already mentioned, to work properly with a forage harvester, the tiller must be at least equipped with a wheel differential to facilitate steering maneuvers. The engine is recommended for gasoline and 8-9 horsepower and above (for shredders 50 to 60 cm wide).

Always remember that the grinder is a “demanding” accessory for the mechanics of the drawbar, in particular for the clutch which could wear out more quickly over time. Therefore, it is necessary to purchase mulchers of the correct size for the tiller to which they will be attached, and prefer tillers with powerful clutches. Currently, the motorized tractors of the BCS group (therefore also Ferrari and Pasquali) equipped with multi-plate clutch in the PowerSafe oil bath, I can say from direct experience that they have proven to be excellent at handling the mechanical stresses of using a crusher. I remind you once again how having independent brakes on both wheels is almost a necessity if you work on slopes or on very uneven ground, which requires a lot of manoeuvres.

self-propelled chipper

For those who don’t own a tiller and don’t need to purchase one, it might be more appropriate to consider purchasing a self-propelled mulcher rather than a tiller attachment.

It is because a machine designed ad hoc doing this work will certainly more compact, balanced, manageable and efficient than a tiller, however the cost will be much higher than the simple mulching attachment that will connect to the PTO.

If you have to work in inaccessible areas, you can look for suitable grinders that are easy to use and comfortable to steer. Even for those who think of using this type of tool very often, the choice of a self-propelled brushcutter becomes practical. This will avoid unnecessary wear and tear on the drawbar and will also save you from having to disassemble and reassemble the various attachments often.
