Abstract

A multi-blade soil handling unit comprising a frame having rearward and forward ends with a pivotal hitch mounted on the forward end of the frame for connection to a prime mover. A transversely extending axle is mounted on the frame and is provided with a pair of ground engaging wheels on opposite ends thereof. A front blade is mounted on the frame forwardly of the wheels and a rear blade is mounted on the frame rearwardly of the ground engaging wheels. A second hydraulic cylinder is connected to the axle and the hitch to pivot the hitch with respect to the frame to permit the selective shifting of weight between the front and rear blades. The blades are normally disposed at opposing angles and are each individually angularly adjusted with respect to the frame and are each laterally adjustable with respect to the frame. The ends of each of the blades may also be raised or lowered by means of shims.

Claims

1. A blade unit, comprising,

a longitudinally extending frame means having rearward and forward ends and transverse sides,

a transversely extending axle means operatively secured to said frame means and having ground engaging wheels at the opposite ends thereof

a front blade section operably secured to transverse sides of said frame means forwardly of said axle means, and adapted to move material from one side of said frame to the other,

a rear blade section operably secured to transverse sides of said frame means rearwardly of said axle means, and adapted to move material from one side of said frame to the other,

a first hydraulic cylinder means operatively connected to and extending between said frame means and said axle means for raising and lowering said wheels with respect to said frame means,

a forwardly extending hitch means operatively secured to said frame means at the forward end thereof, said hitch means being pivotally secured to said frame means about a horizontal axis,

a second hydraulic cylinder means operatively connected to and extending between said axle means and said hitch means to pivot said hitch means with respect to said frame means in response to raising or lowering of said frame and to permit the selective shifting of weight between said blade sections.

2. The blade unit of claim 1 wherein each of said front and rear blade sections are selectively laterally adjustably mounted on said frame means.

3. The blade unit of claim 1 wherein each of said front and rear blade sections are selectively angularly mounted on said frame means.

4. The blade unit of claim 3 wherein said blade units are normally positioned on said frame means so as to be at opposing angles relative to each other.

5. The blade unit of claim 1 wherein adjustable mounting means is provided between each of said front and rear blade sections and said frame means so that the outer ends of said blade sections may be raised or lowered relative to said frame means and relative to the other end of said respective blade sections.
