A vehicle seat suspension for isolating vertical ride vibrations at low frequencies normally found in larger tractors or other vehicles, and to do this without penalty of large static deflection normally required to obtain similar isolation in the typical mass-spring damper isolation suspension system.

A self-powered wireless transducer is disclosed for monitoring external physical conditions, such as excessive vibrations in a bearing. The transducer includes an energy conversion source, such as a piezoelectric sensor to sense the external physical condition and create a power and characteristic signal that is used to power an RF transmitting circuit. A transmitter is provided to transmit signals indicative of the external physical condition, or changes in that physical condition, such as increased vibrations in a bearing to detect bearing faults before a breakdown. In this manner, the monitored machinery can be shutdown in an orderly manner and preventative maintenance can be completed. The self-powered wireless transducer includes an voltage storage device to receive electrical voltage from the piezoelectric sensor and a voltage detector to detect the level of voltage on the voltage storage device. Once the voltage detector detects a level of voltage at a predetermined level, an oscillating transmitting circuit is activated for a brief hysteresis period of the voltage detector.

A variable speed plow bottom has a moldboard structure (37) pivotally connected to a fixed portion which includes a frog (14) and a share (17). The pivotable moldboard structure (37) includes an arm (53) whose forward end (52) is pivotally journaled on a vertical axis (49) in a socket (51) in the point (16) of the frog (14) forwardly of the moldboard (18). The moldboard structure (37) is selectively pivotable about the axis (49) by a hydraulic jack (28) between a low speed plowing position (FIG. 2) and a high speed plowing position (FIG. 3).

A method for preparing a field which has crop residue rows for subsequent row crop planting comprises cutting a plurality of furrows between crop residue rows and lifting and turning over the soil from the furrows into ridges, and simultaneously scraping over a plurality of crop residue rows and transferring the residue into the furrows which are being simultaneously cut, and wherein the former step forms the ridges on surfaces that are simultaneously being cleared by the latter step. The method is accomplished by tillage apparatus including a horizontal frame, a plurality of furrow cutting moldboards affixed to the frame and being curved to lift and turn over the soil cut from the furrows into ridges, and a plurality of trash boards affixed to the frame diagonally to the crop rows and in alternate relation to the moldboards and being curved to transfer the crop residue removed thereby into the furrows being simultaneously cut by the moldboards.
