Abstract: A tractor is provided with a wheel slippage control to regulate the load produced by an implement. Wheel slippage is measured by pulses received from tachometers measuring the rotation of a non-driven wheel and a driven wheel. These pulses are applied to associated counters, where the total number of pulses received from each wheel is continuously counted. If the difference between the counts of the counters reaches a preset amount, a signal is applied to the control valve of a lifting device attached to the tractor, so that an implement carried by the device penetrates less deeply into the soil. After the lifting device has been energized, the counters are reset to zero to continue counting until reset again.

Abstract: A guidance system for use with tractor-mounted row crop cultivators and similar implements includes a pair of independent furrow followers mounted one behind the other on the implement for sensing implement position relative to a preestablished guidance furrow. Series-connected switches are controlled by furrow sensor arms to activate a solenoid valve-controlled hydraulic cylinder on a laterally movable parallel linkage hitch which replaces the standard three-point hitch on the implement. When the implement is raised from the ground, V-shaped stops under the sensor arms automatically position the sensors at the null point. Switches and an actuator on the hydraulic cylinder operate in response to movement of the tractor rockshaft to return the implement to center position in preparation for alignment with the next set of rows to be cultivated.
