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.

In an attaching device for a broadcast fertilizer spreader for mounting of the spreader on a tractor having a three point power lift comprising:
- a. a frame,
- b. a first top link and a coupling element for the first top link pivotally coupling the first top link to the frame, and a first pair of lower lift arms and coupling elements for the first pair of lower lift arms pivotally coupling the first pair of lower lift arms to the frame, both the first top link and the first pair of lower lift arms being for the tractor three point power lift and for actuation to raise and lower the frame by a hydraulic system of the three point power lift,
- c. a second top link pivotally mounted on the frame and a second pair of lower lift arms pivotally mounted on the frame, for attachment of the device to the spreader,
- the improvement which comprises:
- d. the frame comprising two upright supports disposed transversely of the advancement direction of the fertilizer spreader and a cross arm joining upper portions of the upright supports together,
- e. the second top link and the coupling element for the first top link being mounted on the cross arm, and the second pair of lower lift arms, and the coupling elements for the first pair of lower lift arms being mounted on the upright supports, and
- f. a hydraulic system comprising two lift jacks disposed transversely of the direction of advancement of the spreader, each jack having one end joined to one of the upright supports and the other end to the lower lift arm of the second pair of lower lift arms which is coupled to said one upright support.
