Abstract: Apparatus for forming a bale of hay has a wheeled frame that spans a windrow of hay and is moved forwardly therealong, a baling chamber on the frame which receives the windrow as the apparatus is moved along, and means in the chamber for forming the windrow into a spiral bale as the apparatus is moved. A pair of disks are rotatably mounted in the sides of the baling chamber near the rear of the chamber, and the diameter of the disks is a major fraction of the diameter of a finished bale. Endless means which is part of the bale forming means has a lower bale rolling run the sides of which are supported on the disks. The rearward part of the endless means is nearly vertical, and no other part of the endless means contacts the forming bale until after the diameter of the bale is equal to that of the disks, so the bale has a relatively loose core and a firmly packed exterior, and the sides of the bale are relatively smooth and even from being confined between the disks.

Abstract: A flail type manure spreader is provided with a hood that is mounted for bodily movement transversely of the spreader container between a first position in which its discharge side is generally contiguous to the discharge side of the container and a second position in which it straddles the other side of the container. The hood has end walls outside the container end walls that have rollers near the hood discharge side which ride in tracks on the container end walls, and the second side of the hood is carried on links which are mounted on a torsion tube that extends the length of the container. A hydraulic piston is operatively connected to one of the links to move the hood. Overlapping portions of the container end walls and the hood end walls make an effective seal located internally of the tracks, to protect the tracks and rollers from being fouled.

Abstract: A liquid manure spreader has a tank, and a filler opening in the top of the tank is defined by two parallel sidewalls and two connecting walls which extend a substantial distance into the tank. A pair of opposed filler doors are pivoted on the parallel sidewalls a substantial distance below the tops of the walls and are lightly biased to transverse positions in which they abut substantially on the median plane between the sidewalls to close the filler opening. The biasing is light enough that the doors swing downwardly to an open position when liquid is discharged onto them from a filler hose.

Abstract: A wheeled trailer, such as a liquid manure spreader, has a draft tongue which is adapted for attachment to a draft connection of a farm tractor so as to trail behind a soil working implement, such as a liquid manure injector, which is mounted upon the tractor three point hitch; and a driven member, such as a fertilizer pump, is driven from the tractor power take-off which is in a horizontal plane above that of the draft connection. The length of the draft tongue is sufficient to avoid interference between the implement and the vehicle on turns. The power train for the driven member consists of a drive shaft connected to the driven member which is in a horizontal plane below that of the p.t.o., an input shaft on the forward part of the tongue which is in the plane of the p.t.o. and is detachably connected to the p.t.o. by a drive link, and a driving connection between the input shaft and the drive shaft.

Abstract: A liquid manure spreader has a wheeled chassis attachable to a farm tractor, a tank on the chassis, a centrifugal pump on a longitudinal axis immediately inside the front lower extremity of the tank and having a drive shaft extending through the front of the tank for attachment to a tractor power take-off. A discharge pipe extends upwardly from the pump just inside the tank front wall to a T at the top of the tank from one branch of which a horizontal discharge pipe extends through the rear of the tank and has a spray nozzle on its extremity. The other branch of the T extends through the front of the tank and a discharge line on said other branch may be plugged or may have a hose connected to it for supplying a liquid fertilizer injector that is carried on the tractor three point hitch.

Abstract: A wheeled carrier for hay or the like has a low bed that may be tilted from a horizontal transport position rearwardly for rear loading or forwardly for front loading, and has a draft tongue secured by a transverse pivot adjacent a front corner of the bed and swingable laterally about an upright pivot so that the carrier may be towed directly behind a tractor for transporting a load or offset from the tractor for front loading. The bed consists of a set of short front parallel rails and a set of long rear parallel rails; and longitudinal chain conveyor means for both sets of rails has a single drive shaft that extends through overlapping inner end portions of both sets and may be driven in either direction. The extremities of the conveyor means are on idler sprockets with no continuous cross shafts.
