1. Cable-burying apparatus, comprising A. a self-propelled vehicle adapted to be driven over the ground by a riding operator and having a framework, a prime mover mounted at the front end of the vehicle to the framework for propelling said vehicle, B. a housing at the rear of the vehicle and pivotally mounted to the framework for swinging movement in a vertical plane upon a horizontal axis, C. a generally vertical blade adapted to enter the ground and being pivotally secured at its upper end to the housing, D. a first horizontal shaft carried by the housing and having an eccentric mounted thereon, a connecting rod reciprocating by rotational movement of the eccentric and the rod being connected to the blade between the ends thereof so that reciprocation of the rod will cause the bottom end of the blade to oscillate back and forth in a vertical plane parallel with the front-to-back axis of the vehicle, E. power take-off means coupling the prime mover to said first horizontal shaft and including a second horizontal shaft mounted on said framework driven by said prime mover, the axis of said second shaft being substantially coaxial with said horizontal axis, F. flexible power transfer means connecting said first and second horizontal shafts, and G. means operable by the operator while seated on the vehicle and including extensible link means between said housing and framework to cause the swinging movement of said housing without regard to oscillation of said blade, between a position in which the blade is disposed in the ground and a position in which the blade is tilted up and out of the ground.
