Abstract: Spherical mountings are useful for pivotally connecting a push arm of a blade to a track roller frame of a machine. When the blade is removed the bearing assembly must be disassembled and to reconnect the blade to the spherical mounting the bearing assembly needed to shimmed to obtain the correct gap or clearance between the bearing and the spherical mounting. The subject mounting arrangement includes a mounting assembly having a first end portion removeably connected to the push arm of a blade and a second end portion positioned around a spherical assembly and being removeably connected to a bearing assembly of the spherical assembly. This arrangement of components provides for removing the push arm of the blade from the mounting on the track roller frame without removing the bearing assembly.

Abstract: In one aspect of the present invention, an electrohydraulic control device for a drive train of a machine is disclosed. A control member produces an operator control signal. An engine control module receives the operator control signal and responsively reduces the rotational speed of the engine. A transmission control module additionally receive the operator control signal and responsively controls the engagement of a predetermined transmission clutch to reduce the transmitted torque from the transmission.
