As a result, the predetermined length of travel controlled by the automatic depth control circuit 96 is set by a manufacturer of the stump grinder Strobe output G0H latches the Units Inches into a register to display the depth in inches.

The stump grinder 10 includes a frame, generally indicated at The second segment of this wiring harness runs between quick disconnect and control box Automatic depth control is controlled by a microprocessor in the tractor cab, sensors on the implement frame and power beyond valving for hydraulic corrections to maintain a given tool penetration.

Short circuits shall be detected and reported to the processor which will turn off the coil. The automatic depth control system according to claim 5, wherein the counter balance valve is configured to prevent air ingestion, to act as a check valve for cylinder retraction, and to act as a relief valve against over pressurization at the master cylinder; the pressure reducing and relieving valve is configured to provide an adjustable and controlled pressure in the rod side of the outer slave circuit to protect against effects of compression and decompression, to provide for ingest and exhaust of hydraulic oil in order to meet hydraulic fluid requirements caused by draft and draft relief forces, and to restrict the exhaust of hydraulic oil to dampen cylinder movement; and the check valve is configured to operate in conjunction with the pressure reducing and relieving valve to stabilize the positions of the hydraulic cylinders by keeping the cylinders under pressure.

Cap permits the removal of transducer insert The hydraulic position control system according to claim 12, wherein the hydraulic position control system further comprises an adjustable time delay between receiving measured device position data from the device position sensor that indicates a need for a hydraulic correction and providing a hydraulic correction command from the console control unit to the hydraulic position control system, the adjustable time delay synchronizes the application of the position correction to the speed of the device in order to compensate for a spatial offset of the device position sensor and the device.

A shock absorber assembly provides tension to the assembly and dampens shock loads from uneven ground, clumps of dirt and mulch. The first pivot pin 36 permits the upper section 24 to move in a vertical manner relative to the lower section 22 FIGS.

The Console has a LED readout of the rolling average of depth in conjunction with a bar graph depicting variation from the set depth. The automatic depth control system according to claim 1, wherein the first hydraulic valve comprises a check valve. Alternatively, the controller can adjust the operation of the hydraulic system using a measured angle in place of a depth measurement.

Thus, changes from automatic to manual or vice versa require a hoses to be reconfigured. The automatic depth control system according to claim 1, wherein the solenoid activated valves are energized by the hydraulic position control system when operating in the automatic mode and the solenoid activated valves are not energized by the hydraulic position control system when operating in the manual mode.

Similar issues also exist within similar mobile tools such as sprayer booms, road side grass mowers, and other earth moving, working or discharging equipment.

Coil currents of up to 1. Line connects cylinder 96 to line 94 typically using a torque tube to synchronize the parallel cylinders. The actuator block 84 receives pressurized fluid from the feed manifold 82 and regulates the flow of pressurized fluid toward and away from the cylinders 72, 74, 76 and 78 in response to controls from an automatic depth control system 86 to be described.

The LED 15 shows "H. Thus, changes from automatic to manual or vice versa require a hoses to be reconfigured. Channel AN4 receives the value of the Right Sensor 4. Channel AN5 receives the value of the Right Sensor 3.

Rocker switch 25 depth changes go into temporary memory. In these other applications, both tool height and depth above the ground is to be controlled.

It is intended that the scope of the invention be limited not with this detailed description, but rather by the claims appended hereto. Line 76 also connects to check valve A second wiring segment comprising a plurality of connections runs between quick disconnect and each of the valves themselves.

The console receives analog signals from the gauge wheels through interface and generates and receives to and from the hydraulic system through connection The toggle switches 94 A94 B and 94 C enable the operator to move the stump grinder 10 in the vertical direction, lateral direction, and in the axial direction, respectively.

The processor generates output signals which are transmitted to a display to provide information to a user. The default mode on reset shall enable UMM operation.

Thus, height of the frame above the ground, which determines tool penetration, could be hydraulically changed to a more shallow depth ie.

The controller within the Console effectuates operation of the individual valves by sending control signals down this harness to each of the valves individually. Positions are READ only, and positions can be changed by using the rocker switch.

The automatic depth control system according to claim 1, wherein the solenoid activated valves are energized by the hydraulic position control system when operating in the automatic mode and the solenoid activated valves are not energized by the hydraulic position control system when operating in the manual mode.

LED will flash 0. It is also a position for rephasing of cylinders, a cylinder rod position which removes air from the hydraulic circuitry.Automatic depth controlled excavation should be as simple to operate as manual excavation and be effective in limiting digging to the target depth.

The newly developed front attachment control system has improved smoothness in mode change between manual and automatic control.

Simple devices constitution. For automatic control, we.
