    Title: Self-propelled lawn care device carrier vehicle
    The invention relates to a self-propelled lawn care device carrying vehicle as well as an operating method therefor.
    Self-propelled deep aerators are currently limited to small to medium machining depths (max. 100 mm). To this end, these devices are limited to manual operation (walk-behind) and do not offer a driver's seat for the operator. Such a walk-behind aerator is known, for example, from US 7 096 969 B2.
    The soil processing units are combined with the drive and transport system so that they cannot be used universally (several processing units on the same carrier vehicle). On the basis of the adjusted drive control and the use-specific drive work placement, the processing unit can be controlled via automatic operation and is very easy to maneuver. A corresponding vehicle is for example known from US 6 534 388 B1.
    In any case, as a result of the construction method, soil processing units are placed far away from the operator, so that only a limited possibility of control of the processing quality can exist directly by the operator.
    Deep aeration units for medium to large working depths (> 150 mm) and working widths> 1 m have so far been mounted via the standardized 3-point attachment on the rear of conventional wheel tractors and the drive and mounting points have been adjusted accordingly. The processing unit is operated via the manual tractor controls (steering axle, lifting hydraulics) and does not allow automatic operation. Due to the universal tractor construction, this leads to higher ground pressures and larger turning circles than with self-propelled deep aerators with the same working width.
    It must be borne in mind that the usual wheel tractors can be distinguished from the carrying vehicles discussed here on the basis of their mass and their dimensions. Carrying vehicles are generally considerably lighter than wheel tractors and may therefore not exceed a maximum weight (without operator and attachments) of 500 kg.
    Also, in contrast to wheel tractors, carrying vehicles do not normally include a driver's cab.
    Particularly for a field of use for lawn care on golf courses, self-propelled deep aerators are required, which comprise a higher transport speed and greater working depths than the conventional self-propelled. At the same time, automatic functioning must be implementable with the new development.
    It can be regarded as the object underlying the invention to improve the lawn care device carrying vehicles, in particular to enable a larger deployment area, improved control of the processing results and improved security in transport.
    This object is achieved by the subject according to the independent claims. Favorable embodiments are the subject of the dependent claims.

    Preferably, the lawn care device carrier vehicle comprises a right-hand drive actuator and a left-hand drive actuator. It is preferable that the steering device is designed to control the travel drive actuators with a difference in speed, depending on an input angle of the steering wheel, in order to control the direction of movement of the lawn care device carrying vehicle.
    It is preferable that the track width of front wheels and rear wheels is smaller than the working width of the lawn care device to be connected to the lawn care device carrying vehicle.
    The lawn care device carrying vehicle preferably comprises a connecting device, to which the lawn care device can be detachably connected.
    It is preferred that the connecting device is designed for lifting and lowering the lawn care device.
    It is preferable that in the operating state the operating place is in the operating place operating position and the connecting device is in the lowered state.
    It is preferable that in the transport condition the operating place is in the operating place transport position and the connecting device is in the raised position.
    It is preferable that, due to the switch and / or in response to the switch from the transport state to the operating state, the connecting device is movable to a lowered state.
    It is preferable that, due to the switch and / or in response to the switch from the operating state to the transport state, the connecting device is movable to a raised state.

    It is preferred that the lawn care device, in particular the deep aerator, comprises a working width of 1 m to 2 m, preferably of 1.2 m to 1.6 m.
    It is preferable that the operating site operating position is vertically higher than the operating site transport position.
    The invention further provides an operating method for operating a lawn care device carrier vehicle for a lawn care device for lawn care, in particular for a preferred lawn care device, by moving, in particular automatically, an operating location of the lawn care device carrier vehicle to an operating site operating position based on the switch and / or in response to the switch from a transport state to an operating state and moving, in particular automatically, from the operating location to an operating site transport position based on the switch and / or in response to the switch from the operating state to the transport state.
    The requirements can be met by combining a drive and transport unit with an integrated operator position and preferably a zero-turn circle (known as a zero-turn circle) for mowing tractors.
    A carrier vehicle with its own drive source and a height-adjustable driver's seat is proposed that can be used specifically for the use of lawn care operations on the golf course, the driver's position comprising the following operating condition-dependent positions:
    o Transport: lowering the operating place with the attachment mounted; or o Processing: lifting the operating place with the attachment lowered.
    As a result, during the lawn care operations for the operator, a good checking possibility of the processing device and thus a higher processing quality can be guaranteed. Due to the lowering of the operating position at transport speed, the vehicle with the lower center of gravity can be driven over uneven terrain with more certainty.
    The carrier vehicle can be distinguished by the following further characteristics:
    • Control of the steering via a steering wheel;
    • Speed-dependent conversion between the input angle of the steering wheel at the driver's seat and the difference in speed of the drive units on the drive shafts; or • Track widths of front and rear axle wheels within the working width of the processing unit.
    In one version, the vehicle has a driver's seat that can be adjusted in height via hydraulic cylinders. The control system of the hydraulic cylinders or actuating valves can be connected to the vehicle electronics, which moreover can also control the valves of the hydraulic drive of the travel drive.
    Via the operator's choice of operating conditions (e.g. via a switch), the vehicle electronics can activate the control valve of the hydraulic cylinders of the driver's position and change the ratio between the control signal of the valves of the drive motors and the sensor signal of the steering wheel angle.
    In a further embodiment, the adjustment drive of the driver's seat and / or the drive drive motors are electrically operated.
    Embodiment examples are further clarified below with reference to the accompanying drawings. It shows:
    FIG. 1 shows an embodiment of a lawn care device carrying vehicle in top view
    FIG. 2 the lawn care device carrying vehicle of FIG. 1 in the transport condition;
    FIG. 3 the lawn care device carrying vehicle of FIG. 1 in the operating state;
    FIG. 4 is a schematic view of the control of the lawn care device carrier vehicle.
    Reference is made to FIG. 1 to FIG. 3, showing a self-propelled lawn care device as a rough vehicle 10. The lawn care device carrier vehicle 10 comprises a vehicle frame 12. The vehicle frame 12 provides a mounting structure for the individual parts of the lawn care device carrier vehicle 10.
    The lawn care device carrier vehicle 10 comprises a drive device 14, which provides driving force for advancing the lawn care device carrier vehicle 10 and for driving the extension unit. The driving device 14 can be designed electrically or as a combustion drive.
    The lawn care device carrying vehicle 10 includes a non-driven pair of front axle wheels 16 in its front area. The front axle wheels 16 are preferably supported by the vehicle frame 12. Each front axle wheel 16 is preferably arranged to be rotatable horizontally.
    The lawn care device carrying vehicle 10 further comprises a pair of rear axle wheels 18 that can be driven by means of the driving device 14. Each rear axle wheel 18 can be driven separately and independently of the other rear axle wheel 18. For this purpose, each rear axle wheel 18 comprises its own travel drive actuator 19.
    The lawn care device carrying vehicle 10 further comprises an operating location 20 for an operator B. The operating location 20 is, for example, designed as a seat. In this example, the operating position 20 is arranged behind the front axle wheels 16 in the longitudinal direction of the lawn care device carrying vehicle 10. Further, in this example, the operating location 20 is viewed in the longitudinal direction such that the operating location 20 is located in the vertical direction above the rear axle wheels 18. The operating location 20 comprises at least one operating location actuator 22, for adjusting the height of the operating location 20, or for raising or lowering it.
    Furthermore, the lawn care device carrying vehicle 10 comprises a steering device 24 which is arranged such that the steering device 24 can be operated from the operating location 20. The steering device 24 preferably comprises a steering wheel 26. The steering device 24 can also include other operating devices.
    Moreover, the lawn care device carrying vehicle 10 comprises a connecting device 28, to which a lawn care device 30 can be connected. The connecting device 28 comprises at least one connecting device actuator 32, with which the connecting device 28 and thus the lawn care device 30 can be raised or lowered.
    In the present exemplary embodiment, the lawn care device 30 is a deep aerator 34, but can in principle also be any other type of lawn care device. The lawn care device 30 is connected to the connection device 28.
    The switching of the lawn care device carrier vehicle 10 is further explained below with reference to Fig. 4. The lawn care device carrying vehicle 10 comprises a power distribution system 36, to distribute the driving force provided by the drive device 14 to the driving drive actuators 19, the operating position actuator 22, the connecting device actuator 32 and / or the lawn care device 30.
    The power distribution system 36 may, for example, be a hydraulic system 38. In this case, the actuators 19, 22, 32 are preferably designed as hydraulic cylinders or hydraulic motors, respectively.
    An electrical system is also conceivable. In the case of the electrical system, the actuators 19, 22, 32 are designed as electrical actuators, for example electric motors.
    For driving the lawn care device 30, a power take-off shaft, a hydraulic connection or an electrical connection can be provided, in order to make a drive possible for each drive method of the lawn care device 30.
    Regardless of the implementation of the power distribution system 36, the distribution of the driving force in the power distribution system 36 is controlled by a control device 40.
    Apart from the other steering methods, the steering method and the special operating method are discussed in particular below.
    The lawn care device carrying vehicle 10 is first in the transport condition, as shown in FIG. In the transport condition, the connecting device 28 and, as a result thereof, also the lawn care device 30 is in the raised state. The operating location 20 is in the lowered state, which is also referred to as an operating location transport position and is shown in FIG.
    In the transport condition, a center of gravity S of the lawn care device carrying vehicle 10 is thus lower than in the operating condition to be described. As a result, the lawn care device carrier vehicle 10 lies better on the ground when the lawn care device carrier vehicle 10 is moved over uneven terrain. Due to the lower center of gravity S, a swing due to the terrain can be better avoided and thereby the risk of a lateral tilting is reduced. Moreover, with an inclined movement, transversely to an inclined plane or an overhang, smaller tilting moments work around the longitudinal axis of the lawn care device carrier vehicle 10, so that slipping of the lawn care device carrier vehicle 10 or tilting caused by tilting can be better avoided. Thus, even with faster movement in the transport condition, the lawn care device carrier vehicle 10 can be used more safely.
    During a bend movement, the operator B operates the steering wheel 26 in the desired direction of travel. An angle sensor 42 picks up the current input angle of the steering wheel 26 and transmits it to the control device 40. The control device 40 determines a difference in speed for the rear axle wheels from the input angle in a manner known per se 18. Does the operator turn slightly to the right , the speed of the right-hand drive actuator 19a is lowered and the speed of the left-hand drive actuator 19b is increased. The lawn care device carrying vehicle 10 thus travels a right turn, the front axle wheels 16 following the movement. With a left-hand bend the steering takes place in reverse. The turning circle is reduced in this way. In an extreme case, this method of control allows a rotation at the location.
    To operate lawn care, the operator B changes, for example by operating a switch 44. In response to the change from the operating state from the transport state to the operating state, the control device 40 controls at least the operating position actuator 22 such that the operating location 20 is raised to a operating site operating position, shown in FIG. It may also be provided that during the switch and / or in response to the change of the operating state, the connecting device actuator 32 is controlled such that the connecting device 28 and, as a result, the lawn care device 30 are brought into the lowered state. This can take place substantially simultaneously with the movement of the operating location 20 or take place one after the other. In order to keep the center of gravity S as low as possible during the switch and thereby achieve a higher stability at the switch, the lowering of the connecting device 28 can preferably be started or closed to lift the operating place B.
    In the operating state, the connecting device 28 and, as a consequence thereof, the lawn care device is also in the lowered state. The operating location 20 is in the operating location operating position. Thus, the eyes of the operator B are also in the raised position. In general, this allows the operator B to oversee a larger ground area in the operating position than in the transport condition. In particular, the operator B is brought to that location before observing the bottom portions BB covered by the lawn care device carrying vehicle 10 and / or the lawn care device 30. As a result, the operator B can more easily assess the quality of the processing results and in any case make corrections to the lawn care device 30. Thereby, it is not necessary for the operator B to step away from the lawn care device carrier vehicle 10.
    The measures proposed herein can improve lawn care device carrying vehicles. In particular, the reliability of use in the transport movement can be increased, while at the same time an improved control of the processing results is made possible during the processing movement. Furthermore, the maneuverability can be increased if the drive wheels are driven with different drive speeds. In an extreme case, a rotation on the site may be possible.
