Abstract
An aerator implements a drive system with an outboard transmission(s) in which the transmission(s) is arranged outwardly of a frame rail(s) of the aerator's chassis to deliver power to both a drive wheel(s) and a driven set of tines of a tine assembly. The tine assembly may include at least one non-driven or freewheeling set of tines between outer sets of driven tines. An adjustable depth control system allows for selecting a tine depth that can achieved through a single button push that lowers the tine assembly to the selected depth.
Claims19
An aerator comprising:
- a chassis that includes a frame with a first support and a second support that are laterally spaced from each other;
- an engine that is supported on the frame;
- a tine assembly that is supported by the frame and that is configured to engage and aerate a ground surface;
- and
- a drive system that is mounted to the frame and that is configured to receive power from the engine and to deliver power to the tine assembly, the drive system including a transmission that is supported by the chassis outwardly of a respective one of the pair of supports and that is configured to deliver power from the drive system to the tine assembly.
2 more elements
An aerator comprising:
- a chassis that includes a frame with a first frame rail and a second frame rail, wherein a distance between the first and second frame rails corresponds to a frame width dimension of the chassis;
- a tine assembly that is supported by the frame between the first and second frame rails;
- and
- a drive system that is mounted to the frame and that is configured to deliver power to the tine assembly, the drive system including:
- a first drive motor that is supported by the frame with a first motor output shaft that extends outwardly beyond the first frame rail;
- a second drive motor that is supported by the frame with a second motor output shaft that extends outwardly beyond the second frame rail;
- a first drive wheel that is supported by the frame outwardly of the first frame rail;
- a second drive wheel that is supported by the frame outwardly of the second frame rail;
- a first transmission that is configured to transmit power from the first drive motor to the first drive wheel, wherein the first outboard transmission is supported by the frame laterally outside of the frame and between the first frame rail and the first drive wheel;
- and
- a second transmission that is configured to transmit power from the second drive motor to the second drive wheel, wherein the second outboard transmission is supported by the frame laterally outside of the frame and between the second frame rail and the second drive wheel.
8 more elements
An aerator comprising:
- a chassis that includes a frame with a pair of frame rails that are laterally spaced from each other;
- an engine that is mounted to the frame;
- a tine assembly that includes multiple tines, wherein the tine assembly is configured to engage and aerate a ground surface with the tines;
- a tine assembly support system that connects the tine assembly to the frame at a variable position with respect to the frame between a raised position and a lowered position, wherein a travel distance between the raised and lowered positions can be varied to provide an adjustable depth of the tine assembly;
- and
- an adjustable depth control system that is configured to vary the travel distance between the raised and lowered positions of the tine assembly;
- where the adjustable depth control system comprises:
- a depth control arm that includes:
- an arm base that is mounted to and moves in unison with the tine assembly support system;
- an adjuster that is mounted at a variable position to the arm base, wherein changing a position of the adjuster with respect to the arm base changes a maximum depth value of the tine assembly.
