Abstract

A loader attachment 30 is mounted on or dismounted from a tractor 12 by connecting uprights 36 and 38 to socket assemblies 32 and 34 or releasing the uprights from the socket assemblies. A boom assembly 40 is pivotally attached to the uprights 36 and 38 by pins 42. Both lift cylinders 104 and 112 pivot the boom assembly 40 relative to the uprights 36 and 38. The socket assemblies 32 and 34 are rigidly secured to the tractor 12. The connection is made by moving the troughs 128 into engagement with the pins 180 and then rotating the uprights 36 and 38 about the pins 180 until the vertical surfaces 142 and 150 on the upright wedges 140 and 148 contact the vertical surfaces 192 on the socket wedges 190 and the inclined surfaces 144 and 152 on the upright wedges 140 and 148 engage the inclined surfaces 194 on the socket wedges 190. The locking pins 186 are then inserted through bushings 184 and bores 134 to lock the uprights 36 and 38 to the sockets 32 and 34. The procedure is reversed for dismounting.
