An aerator for a turf surface has a traction control, an OPC bail, and an aeration bail capable of single handed operation. A controller automatically lowers a tine head to begin aerating at a start location marked when the aeration bail is closed and lifts the tine head to end aeration at an end location marked when the aeration bail is released. The controller further causes the tines that enter the turf surface at the start location to penetrate to a desired hole depth. The controller also automatically adjusts ground speed to maintain a desired hole spacing during an aeration pass, but permits the operator to speed up during a turnaround between passes with a steerable front wheel freewheeling to mitigate wheel scrubbing. A handle assembly having a spring counterbalance is height adjustable and automatically engages a parking brake when placed in an upright non-operating position.

The drive shaft is connected to the output shaft by means of a power transmission means to allow the drive shaft to be driven by the drive unit, and the drive unit is connected to the work implement as a counterweight for the work implement in such a way that the drive unit descends when the work implement is ascended and ascends when the work implement is descended.

A self-propelled lawn care appliance for aerating and subsoiling the ground below a turf includes a chassis, an implement with piercing tools movable up and down for piercing the ground for subsoiling, and an optical lane recognition device comprising at least one camera and an image processing unit. In a first mode of operation of the lawn care appliance, the lane recognition device is designed to recognize a hole pattern of an area of the ground previously treated by the lawn care appliance and, based thereon, a boundary of a previously treated lane. In a second mode of operation of the lawn care appliance, the lane recognition device is designed to recognize a defined boundary of the deposited soil material of a ground area previously treated by the lawn care appliance and, based thereon, the boundary of a previously treated lane.

A self propelled aerator and fertilizer apparatus 10. The apparatus 10 includes an elongated frame 12, having front wheels 20 and rear wheels 22 coupled to the frame. A steering wheel 30 which controls the front wheels 20 is provided so that the apparatus 10 can be moved in a predetermined direction. An aerator 34 is coupled underneath a lower intermediate portion of the frame 12 for aerating the soil upon rotation thereof when the aerator is moved up and down to selectively engage the soil. A fertilizer 90 is coupled to an upper end portion of the elongated frame 12 so that fertilizer can be dispensed into the soil after aeration is accomplished.

Injection device and procedure for using the device for introducing air and/or additive to the deeper layers of soil The subject of the invention is an injection device and procedure for using the device for introducing air and/or additive to the deeper layers of soil, which device is suitable for introducing air and/or additive to the deep layers of soil with high pressure, where the arrangement of the device makes sure that air and/or additive is spread to a large area, and it also ensures that the air and/or additive cannot flow back to the surface along the device. Furthermore, with the help of the procedure while using the device it is possible to introduce proper quantity of air and/or additive into the deeper layers of the soil corresponding to the given soil quality. Injection device consisting of base body having longitudinal hole, and one end of the base body is formed with tapered tip, and there are holes in the lower and upper parts of the base body, which are connected to the longitudinal hole. It is characterised by that there is a tapered tip (3) having length LI formed with rim (4) at one end of the base body (2) having length L and an axis t of the device (1), above which a tapered injecting part (5) is established with length L2, at the bottom of which injecting part (5) one or more hole(s) (6) are established, the axes of which holes (6) are aligned in the same plane or in separate planes above one another, and a tapered neck part (8) having length L3 is formed above the injecting part (5), and a ring (17) is fixed at the interface of the neck part (8) and the holder part (9) which is formed with supporting rim (10) at its upper area located above the neck part (8) with length L4 and diameter D3, and a compression ring (18) is placed in a movable manner above the ring (17), and a ring (19) is located on the base body (2) between the compression ring (18) and the supporting rim (10), furthermore a rubber seal (23) is placed on the fastening part (12) having length L5 and diameter D3 and is provided with a hole (13) above the supporting rim (10), and a clamp (20) with input pipe (21) is placed on the rubber seal (23) so that the input pipe (21) is located directly above the hole (13), and there is a hole with Morse taper (16) in the coupler part (14) having length L6 and diameter D4 established with rim (15) above the fastening part (12), and a longit

A stand-on aerator includes a chassis, an operator platform extending from a rear portion of the chassis, an aerator assembly coupled to the chassis and having a plurality of reciprocating tines configured to extend from and retract into the aerator assembly, and an object detection sensor. At least a portion of the plurality of reciprocating tines are configured to retract in response to the object detection sensor detecting an object in a path of the aerator assembly.

A turf aerator includes a retracting tine assembly and an input mechanism. The tine assembly includes a plurality of tines, a pair of swing arms, and a linkage for selectively moving the pair of swing arms and the plurality of tines from the operating position to the retracted position. The pair of swing arms support the plurality of tines and are configured to rotate the plurality of tines between an operating position to a retracted position. The input is coupled to the linkage and the input is operable to active the linkage to move the pair of swing arms and the plurality of tines from the operating position to the retracted position.

An agricultural tillage implement has a vertical tillage section and an aerating section behind the vertical tillage section, each extending substantially perpendicular to the pull direction of the implement. Individual vertical tillage elements, such as disc blades, can be indexed with individual rotary tine assemblies of the aerator section so that discrete holes formed by the aerator section are positioned between substantially continuous slits formed by the vertical tillage section. A ground deposit system deposits a component on the ground and may be configured for conducting and depositing a granular component, such as seeds, fertilizers, minerals or the like, or liquid components, such as liquid manure.
