Similar difficulties arise with a front attachment device such as that in the United States patent 1. Combine harvester with interchangeable with-2 763 115 is described, as this is also known at least one hydraulic cylinder raised the solution of replacing the front attachment only and lowerable front attachment, which can be carried out with two equal 5, if the driver of two-axle, at a distance from each other nem seat descends Likewise cumbersome and time-bearing journals The exchange of the front attachment is required on the front of the machine nenrahmens provided above the hydraulic cylinder of the French patent 1 400 193, since there linder arranged bearing recesses introducing the union of the mowing table to be connected bar and can be locked therein, characterized by ίο carried out by a bolt screw connection, that at the front of the must. It is just as cumbersome and time consuming • Combine harvester firmly together by opening, connecting and loosening the front attachment in the exception yoke (43) connected ramps (40) citation according to the French patent specification are sorted by that of the machine frame 1 469 733, as there too the driver and the driver's seat men descend facing away from the end of the hydraulic cylinder 15, one end of the elevator un- (50) lead and lift to de "bearing recesses (24) and into the intended bearing recess at both ends are pivotally connected, and that introduce mung and then in the same way the anik Lift the bearing recesses (24) from the driver's side of the elevator and lock them in place seat from the locking bolt (30) to be actuated must be locked, in order then to then still be the hydraulic bar. to verbir ao linder the reel with the combine harvester, 2.

The latches provided for locking 3. Combine harvester according to claim 1, characterized in that 25 ken can also only be brought into the closed position, that they move away from the machine frame when an operator or the one from the seat turned ends of the ramps (40) with descended drivers for a correct intervention hook-shaped recesses (42) open at the top. All known versions are therefore provided are. mean that they are cumbersome and time consuming and just 30 can be carried out if an operator provides assistance. The object of the invention is to provide this associated with the cultivation or replacement of the front attachment To make work much easier and to do it by machine, controlled from the driver's seat. The invention relates to a combine harvester. To solve this problem, in a combine with exchangeable with by means of at least one thresher of the previously explained type according to the Er hydraulic cylinder Raisable and lowerable front attachment, found on the front of the combine harvester with two equiaxed, at a distance from each other firmly connected by a mounting yoke Placed bearing journals placed in at the front of the 40 ramps leading from that of the machine-machine frame provided bearing recesses arranged above the hydraulic frame facing away from the hydraulic cylinder, leading to the bearing recesses and at both ends bar and is lockable therein. are pivotally connected; the bearing recesses It is well known that combine harvesters are not only used for blocking harvesting that can be operated from the driver's seat of grain, but also for harvesting 45 bars lockable. Maize, peas and other grain crops are used. For one crop at a time, a thresher is then only driven towards the front attachment. Included Different front attachment required. The front attachment is raised by the rear end of the front attachment and are therefore interchangeable on the machine frame slides with its pin along the ramps up to of the combine harvester. 50 the connecting means interlock. The ram To carry out the exchange must act here as a support and sliding surfaces and after the pen USA.-Patent 3 026 664 the driver, if it is so cheap because with this embodiment all of them not even a second man for support arranged means for lifting on the combine harvester is pulled, dismount from its seat, must be from, except for the sliding bolt, and therefore only once Loosen the bottom of the lock, the bearing pin 55 is required. of the previously connected device from the storage The locking bolts are expediently via angle lever remove the recesses and the device can be operated on the bow rod by means of a control rod,

This solution, the work apart from the machine frame, is complex and time-consuming. Since mower-turning ends of the increasingly trained junkers are only required for a very short period of the year, but most of the work is required in pens with hook-shaped gates that are open at the top. With these hook-shaped recesses, this loss of time weighs heavily, especially 65 recesses, the front attachment can be lifted on its spigot if in one day according to the different crops to the storage place or in a Pocht1 tire different harvests can be moved to the attachment position,
