A roller assembly including: a frame; a first undercarriage connected to the frame, the first undercarriage comprising: a first body; a rear roller connected to the first body; and a first overlapping roller that is elongate and connected to the first body; and a second undercarriage connected to the frame, the second undercarriage comprising: a second body; a front roller connected to the second body; and a second overlapping roller that is elongate and connected to the second body, wherein the first undercarriage is positioned adjacent to the second undercarriage such that the first overlapping roller overlaps the second overlapping roller.

A land roller implement includes a wheel aligned with the respective gap between the inner roller and the outer roller of each wing in which the wheel is pivotal between a packing position in the working position of the rollers and a transport position supporting the rollers in the transport position of the implement. The wings can also include a drive motor associated with each transport wheel to drive forward rotation of the wheel for displacing the wings from the transport position to the working position without displacing the implement in a rearward direction. A levelling beam attachment and a seeding attachment can also optionally be used on the land roller implement. Optional latchable brace members pivotally supported on the wings may provide additional support to the wings when using the levelling beam attachment.

A land roller is provided with an over-center locking linkage arrangement to help lock a roller frame of the land roller into a raised transport configuration to reduce the likelihood that a failure of the actuator system could cause the roller frame to inadvertently fall and injure a person or cause damage to property. The land roller may be further provided with actuators that are controlled in temporal series from a single controller to simplify and increase the safety of both converting the land roller between the transport configuration and a working configuration and converting side frame sections of the land roller between folded and unfolded positions.

This invention relates to a mounting assembly for a roller having a bearing and a fastener. The fastener is at least partially shrouded by a sleeve, the end of which is keyed into the roller. Use of the sleeve provides an additional bearing surface to allow the roller to rotate with the bearing. Should the bearing seize, the sleeve and the roller are still able to rotate without affecting the fastener, that is, the fastener does not unravel and disengage from the housing. This invention has particular application to mounting of rollers to mower decks of a mowing implement.

Disclosed herein are roller devices and system for compressing a medium comprising: a) an attachment frame configured to connect to a powered machine, the attachment frame comprising at least one support arm having first and second opposed ends, the first end having a first pivot portion configured to receive a pivot member, and the second end being configured to connect to a portion of the powered machine; b) a roller assembly comprising: i) at least one rotatable roller component, and ii) at least one roller frame having first and second ends, the first end being rotatably connected to a first end of the roller component with a rotating means configured to allow rotation of the roller component, the second end being rotatably connected to a second end of the roller component using a rotating means configured to allow rotation of the roller component, and the roller frame having a second pivot portion being configured to connect to the first pivot portion; and c) a pivot member configured to connect the first and second pivot portions. Also disclosed herein are methods of using the disclosed roller devices and systems.

Herein is described an agricultural device that can include a frame; and a plurality of roller-crimping devices supported by the frame arranged in at least one row oriented in a direction that is transverse to a direction of travel of the agricultural device. Each of the plurality of roller-crimping devices having an exterior surface configured to at least partially crush stems of residual plant matter, and being individually movably mounted to the frame such that each of the plurality of roller-crimping devices will move at least vertically with respect to the frame when subjected to a temporary increase in resistance caused by an encounter with a non-uniform region in the field.
