Abstract: In a sickle cutting apparatus including a row of stationary knife guards and a sickle bar with a row of blade sections for reciprocating movement mounted thereon, each of the blade sections is simply removable from the sickle bar for replacement by mounting a rear plate portion on the sickle bar where each of the rear plate portions has a pair of holes bolted to mating holes in the bar and each hole in the blade is connected to an associated slot extending rearwardly in the rear plate portion from the hole to a rear edge. In this way the blade section can be pulled forwardly by loosening the bolt and sliding the bolt along the slot until the blade is released. A circular counter-bore in the blade section receives a nut when tightened to hold the blade section in place. The system can be used with pointed guards or stub guards.

Abstract: A crop harvesting header with a cutter bar and a draper assembly has a draper which includes a front edge of the upper run of the draper arranged at a position adjacent to but spaced from the cutter bar and there is provided a sealing member extending along the cutter bar. The sealing member is co-extruded to form a constant cross-sectional shape along the full length and to define a first portion of a stiffer plastics material attached to the cutter bar and a second blade portion of a more flexible plastics material which extends rearwardly from the first portion at the cutter bar to lie over and in contact with a bead along a front edge portion of the draper.

Abstract: A sickle cutting apparatus includes a plurality of triple finger knife guards which are arranged side by side along the cutter bar to cooperate with a reciprocating sickle bar carrying a row of double blade knife sections and a set of hold-down members carrying hold-down fingers. The hold-down members are arranged alternately as a single finger and double finger with each hold-down member being connected to the cutter bar in association with a respective triple guard. In this way the hold-down fingers are arranged at alternate guard fingers leaving the intervening guard fingers open. The system includes both pointed guards with no tang and stub guard so that the user can select either to be used with the hold-downs. The hold down fingers are all individually adjustable so that the double hold-down have two adjustment screws which can be individually operated causing flexing of the bridge between the double fingers.

Abstract: A crop harvesting header with a cutter bar and a draper assembly has a draper driven by a drive roller at one end and an idler roller at the other end. The draper is carried on a plurality of support rollers parallel to the first and second rollers for supporting the upper run of the draper at spaced positions therealong. The draper includes a front edge of the upper run of the draper arranged at a position adjacent to but spaced from the cutter bar and there is provided an integral extruded sealing member extending along the cutter bar defining a first stiffer portion attached to the cutter bar and a second flexible blade portion which extends rearwardly from the first portion at the cutter bar to lie over and in contact with a bead along a front edge portion of the draper.

Abstract: A method for conveying crop has a crop conveyor belt driven by a drive roller with a cylindrical roller body having an outer surface surrounding an axis of rotation of the roller for engaging an inner drive surface of a canvas wrapped therearound. The roller has a plurality of raised spaced elements such as ribs formed of a hard wear resistant material such as carbide clad onto the outer surface metal of the roller body. The ribs extend along a part only of the body at the two ends in an axial direction and angularly spaced around the outer surface. The ribs have a height less than 6 mm and a width less than 6 mm arranged such that the ribs do not engage into any recesses in the drive surface of the.
