Abstract
To facilitate broadcasting fertilizer from different levels above the ground, in addition to linkages for mounting the device on a three point power hitch of the tractor, linkages and an accompanying hydraulic system are provided for elevating the spreader above the level to which the tractor power hitch can raise it. The device comprises an open frame 2 formed by upright supports 5 and a cross arm 4. The open frame construction facilitates the connection of the tractor power take-off shaft to the spreader, and the connection of linkages between the tractor and spreader for control of the metering mechanism of the spreader.
