1. Apparatus for injecting liquid manure into the ground and for spreading the liquid manure in the ground, said apparatus being adapted for use with a forwardly traveling vehicle carrying a tank of liquid manure, said apparatus comprising upper and lower axially spaced and axially alined sleeves, means for mounting said sleeves non-rotatably on said vehicle in an upright position, an elongated pipe telescoped into and rotatable within said lower sleeve and having upper and lower ends projecting beyond the upper and lower ends of the lower sleeve, a collar located between and rotatable relative to said sleeves, said collar being connected to the upper end of said pipe and being engageable with the upper end of said lower sleeve to prevent said pipe from sliding downwardly within said lower sleeve, means for releasably coupling said collar to said pipe to permit said pipe to be withdrawn from said lower sleeve out of the lower end of the lower sleeve, a flexible hose communicating with said tank and having an outlet end portion telescoped into said upper sleeve, the outlet end portion of said hose having a reduced diameter lower end telescoped into and communicating with the upper end of said pipe to deliver liquid manure into the pipe, a generally circular disc mounted rigidly on the lower end portion of said pipe to rotate in unison with the pipe and to slice through the ground during forward travel of the vehicle, the underside of said disc being downwardly concave and defining a baffle around the lower end of the pipe, and the periphery of said disc being formed with angularly spaced notches whereby liquid manure delivered to said pipe is injected into the ground through the lower end of said pipe and is spread into the ground by the rotary disc while flowing radially out of the notches in the periphery of the disc.
