Abstract: The equipment system consists essentially of the undercarriage 101 having supporting wheels, the rotary device with dovetailing prongs 102, the sowing machine 103 and the land roller or clod breaker apparatus 104. The system components may be used in various combinations or individually.

Abstract: A power take-off shaft driven combination machine for ground preparation which can be coupled to a tractor vehicle is equipped, with a view to a short, light and constructionally simple construction, with levelling tools 107 arranged directly behind the tractor vehicle 38 which level the wheel tracks left by the tractor vehicle 38, with a rotor-tiller 20 arranged between the levelling tools which is driven via the power take-off shaft in a direction of rotation U which sustains the direction of travel F and which throws the excavated earth against a movable rake 24 or against a flexibly arranged mat 31 and with a vertically adjustable crushing roller 202 arranged therebehind which has a peripherally at least substantially closed roller body 203 with peripherally directed rows of teeth 204 and scrapers 207 arranged between and spaced apart from the rows of teeth.

Abstract: An attachment for agricultural machines includes a frame having a leading and trailing portion, a first soil-treating unit located at the leading portion of the frame and a second soil-treating unit located at the trailing portion of the frame. Between the first unit and the second unit there is located on the frame wheels for supporting the frame when an agricultural machine provided with the attachment moves along a road. The wheels are displaceable relative to the frame between a first position in which the wheels engage the ground and a second position in which the wheels do not engage the ground. The frame is so coupled to a lifting device of the agricultural machine that, when the wheels are in the second position, the trailing portion of the frame is supported on the ground by the second soil-treating unit.

Abstract: An arrangement for coupling a cultivating attachment to a cultivating machine has a spring-suspended support articulately coupling a respective roller unit of the attachment to a main frame of the machine. The support includes elements for adjusting the relative elevation of the main frame and the roller unit while permitting relative vertical movement between the same. The support includes spring element opposing such relative movement with shock-absorbing action. A blocking element is provided cooperating with the spring-suspension support and movable between a blocking setting preventing the above-mentioned relative movement and an unblocking setting not preventing such limited movement.
