Harvesting device of an agricultural harvesting machine, comprising a housing (17), comprising at least one rotatably driven apparatus (15) which has a shaft (18) and is rotatably mounted by the shaft (18) relative to the housing (17) about the longitudinal axis (19) thereof, comprising a sealing disk (21) which acts on the housing (17) and which is fixed relative to the shaft (18) for sealing the housing (17) relative to the shaft (18) in the region of a feed-through of the shaft (18) through the housing (17), wherein the sealing disk (21) has a through-passage (22) for the feed-through of the shaft (18), wherein when viewed in the radial direction of the shaft (18) a slide bearing joint bush (25) is arranged between the shaft (18) and the sealing disk (21).

A disk assembly for agricultural implements comprises a disk hanger including a proximal end and a distal end opposite the proximal end. The disk assembly further includes a hanger spindle supported relative to the distal end of the disk hanger for rotation about a first axis of rotation, and a blade spindle supported relative to the hanger spindle, with the blade spindle being rotatable about a second axis of rotation oriented non-parallel relative to the first axis of rotation. Additionally, the disk assembly includes a blade coupled to the blade spindle for rotation therewith about the second axis of rotation. Moreover, the disk assembly is configured such that rotation of the hanger spindle relative to the disk hanger about the first axis of rotation results in an adjustment of both an angle-of-engagement and a camber angle of the blade.

A safety guard support for a power take off shaft, the safety guard support including a bearing; and a retainer ring. The bearing and the retainer ring including corresponding interlocking formations configured to prevent rotation of the bearing relative the retainer ring about a longitudinal axis.

An extended highspeed rigid hub (EHRH) combined with a specific double roller taper bearing and tapered head bolt coupled with a coulter blade create a coulter blade assembly of great strength which functions to minimize flex at the circumference of the coulter blade. The EHRH maintains inner as well as outer bosses which support both inner and outer attachment points for the taper headed bolts to provide rigidity to the coulter blade. The double roller taper bearing adds to the rigidity equation by mitigating axial as well as radial forces exerted on the coulter blade. The coulter blade assembly, when coupled as one element to an implement, creates a rigid furrowing device capable of precise furrow construction in many challenging soil conditions.

A concentrated high-speed rigid hub allows for heavier planters, high-speed planting and seeding devices in multiple and multiple challenging applications such as no-till, high cation exchange capacity (CEC) soils, compact soils, moist soils, high concentrations of stubble and or Bacillus thuringiensis (Bt) crops, and cover or green crops with massive structured root systems. The hub is made of one of high strength forging steel and medium carbon cast steel, whereby the hub lessons hub flexing, hub bending, cracking and premature failure. The hub comprises rigid, heavy duty deep bosses or gussets which increase structural strength and maximize the strength of attachment points adapted for either bolts or rivets attachment to a blade or object.

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

A bearing assembly engaged with an end of a rotatable shaft. The assembly includes a hub defining a first bore extending between a first opening at a first end of the hub and a second opening at a second end of the hub. A bearing sleeve engaged in the first bore defines a second bore. The shaft's end is inserted through a first opening in the second bore. A sealed bearing located between the bearing sleeve and the hub's interior surface enables relative rotation therebetween. A first sealing mechanism seals the first bore's first opening and a second sealing mechanism seals the second openings of both of the first and second bores. The first sealing mechanism includes an L-shaped ring circumscribing the bearing sleeve and a rubber sealing member. The second sealing mechanism includes a hemispherical region and flange secured to the hub by a retaining ring.
