The baling press serves to press in the agriculture resulting hay, straw or Grassilage for bundles. So it can be stored space-saving. Baling presses are pulled by a tractor and propelled over the power-takeoff.

Today round or right parallelepiped bundle (weight with hay up to 400 piece of kg, with Silage up to over 1000 piece of kg) is usually pressed. These can be moved only with the front loader of a tractor.

The bundles can be bound either with cords or with nets, whereby with the latter between edge tons edge and more cover edge is differentiated. For each of these two methods a special press is needed.


To most common baling press is the 1971 Rundballenpresse invented of the seas company. For the production of these cylindric bundles in it hay is rolled up in simple way. This is done through rubber-occupies belt (press with variable chamber) or via steel rollers (fixed chamber press). If the bundle achieved a certain size, it becomes with ropes or bind for nets, before the rear part of the press opens and the bundle can roll out. The bundles have a diameter of 120-180 cm and are 120 cm broad. The weight amounts to between 150 and 750 kg. While in the USA sea of the main manufacturers remained, these presses are produced among other things today by Welger. In Germany many Rundballenpressen are sold by the manufacturers Deutz driving, Claas, crown, new Holland and John Deere.

Right parallelepiped baling press


Another baling press produces large right parallelepiped bundles, which are fixed with approx. six interlocked cords. These bundles weigh somewhat more than appropriate round bundles. The width of 80-120 cm and the height of approx. 90 cm are certain by the design of the press. The length of the bundle of 100-250 cm is adjustable.


The so-called high pressure bundles (10-25 piece of kg) are particularly interesting for hobby, small or horse farmers without large machinery, which were pressed particularly into the 1960er/1970er-Jahren. These relatively light bundles have the advantage that they can to be moved by a person and therefore no front loader or serious changes require. These bundles are bound with 2-4 cords and to have approximate extents of 38 x 46 x 96 cm. Because of the comparatively high costs in handling many small bundles these are not used longer by large agricultural enterprises. These bundles cannot only be moved but become more simply, also than isolation and building material with the straw ball house assigned.

These bundles are formed as follows: The material which can be pressed becomes by means of a rotary drum with flexible Federzinken, which so-called Pickup carries, by the soil taken up and to a kind pit, which pulls itself over the entire width of the press. In this pit a combination of measurer and piston from a side induces itself to the other one. This happens normally rectangular facing forward. The blade, which is directly before the piston, cuts hay off in the place, where it is carried of the Pickup into the chamber. The piston pushes hay to the rear and compresses it there to a bundle. In this range is measuring instrument, which releases the connection mechanism with reaching a certain hay quantity. Now the bundle is bound by means of one or several cords and separated these. The bound bundle is pressed by the production of the next bundle by the rear opening and lands on the soil. There becomes often comparable by means of a gear wheel, with the odometer of a car, which determines number of ejected bundles.

The automatic baling press for small right parallelepiped bundles differs today not substantially substantially from the model from the year 1940. It was manufactured in the USA first by new Holland and used a small petrol engine as energy source. The basis in addition supplied the 1937 invented baling press with double and automatic admission of the harvested crop.

Their predecessor models required manual binding of the bundles. The predecessor models of these models were installed and over a drive belt were propelled again firmly. Hay had to be brought to the press and filled in manually.

The only substantial change since 1940 was the exchange burn engine by the power-takeoff of the pulling tractor.
