One of the previous posts regarding the comparison of Kubota vs. Power Trac traction makes for interesting discussion.
The Kubota provides power to the wheels through front and rear differentials.
The Power Trac provides power to each individual wheel through a individual wheel hydraulic motor with common
hydraulic pump. Torque is achieved by hydraulic pressure. If one wheel starts to spin, the hydraulic pressure at this individual wheel motor drops (flow increases) since it is spinning faster than the other wheels. Is the torque to the other wheels limited to the amount of pressure to the spinning tire?
Some of you guys that have seat time in your Power Tracs, please give us your experience. If you lift the two front tires off of the ground through front attachment down pressure, the front tires will spin in the air, but is hydraulic pressure still sufficient to move the tractor. Or has the free spinning front tires lowered system hydraulic pressure enough to prevent torque from being delivered to the wheels on the ground.
You guys that have PTs or Earthforce hydraulic driven tractors, try the above and report your experience. Maybe the Power Trac engineers have designed the hydraulic supply so that hydraulic pressure to each wheel motor is un-affected by the traction at the other wheel motors.
