The invention relates to an impact compactor (10) and to a method and system of obtaining an indication of the soil strength of soil (100) by using an impact compactor (10). The impact compactor (10) includes a chassis 5 structure (12), at least one wheel (14) supportively mounted on the chassis structure (12), and at least one impact drum (16) which is displaceable relative to the chassis structure (12). The method includes travelling with the impact compactor (10) over a soil surface (100) while the drum (16) is in a raised position in which it is spaced from the soil surface (100) and 10 measuring, by using a measuring arrangement (20) which is connected to or forms part of the impact compactor (10), a rut depth (54) of a rut in the soil surface (100) which is formed by the wheel (14) as the impact compactor (10) travels over the soil surface (100).

A vehicle includes a frame, a tractive element coupled to the frame, a prime mover coupled to the frame and configured to drive the tractive element to propel the vehicle, and a silage compactor. The silage compactor includes a wheel rotatably coupled to the frame and positioned to engage silage positioned below the frame, a vibrator coupled to the wheel and configured to cause the wheel to vibrate, and a controller configured to control the vibrator to vibrate the wheel while the wheel is in contact with the silage to compress the silage.

A compaction unit configured for use in the compaction of a surface in connection with construction, excavation and other earth-working or related activities. The compaction unit may be configured as an attachment that can be interchangeably attached to various types of construction machines, operating machines and equipment (such as, but not limited to excavators, backhoes and the like). The compaction unit may be configured as single compaction device capable of performing any combination of (i) vibratory compaction, (ii) roller compaction, (iii) and plate compaction. These capabilities enable the unit to function as a single attachment that can operate as a roller compaction wheel, a vibrating roller compaction wheel, and a vibratory compaction plate depending on the desired application and requirements of the operator.

A scraper used with a compactor wheel assembly includes an attachment portion, a scraping portion that forms a first oblique angle with the attachment portion, and a transition portion connecting the scraping portion to the attachment portion. The transition portion defines a stress concentrator for allowing the scraper to break before any structure to which the scraper is attached is damaged.

A soil working roller for a soil processing machine, in particular a soil compactor, comprising a roller shell (44) extending longitudinally in a direction of a roller axis of rotation (D) and delimiting a roller interior (26), at least one ballast unit (46, 48) arranged in the roller interior (26), characterized in that each ballast unit (46, 48) comprises at least one ballast element (54) supported with respect of the roller shell (24) by means of an elastic suspension assembly (58), wherein the at least one ballast element (54) is permanently coupled to the roller shell (24) by the suspension assembly (58) and is movable with respect to the roller shell in the radial direction, axial direction, and circumferential direction, and/or a plurality of ballast units (46, 48) is provided in the roller interior (26) arranged in series in the circumferential direction, wherein each ballast unit (46, 48) comprises at least one ballast element supported with respect to the roller shell (24) by means of an elastic suspension assembly (58).

A work machine includes a frame, a sensor assembly, and an ultrasonic sensor. The frame includes a first portion and a second portion that includes a front bumper and is configured to pivot with respect to the first portion for steering the work machine. The sensor assembly is positioned on the first portion or the second portion of the frame and is configured to sense data for detection of obstacles within a first area around the work machine. The ultrasonic sensor is positioned on the front bumper of the second portion and is configured to sense data for detection of obstacles within a second area around the work machine, the second area outside the first area when the second portion is in an articulated position with respect to the first portion.
