Anyone know how the BX PTO system works?

When you move the lever to engage the PTO on the BX, are you engaging a clutch, or are you opening a hydraulic valve that sends fluid to a hydraulic motor that makes the PTO turn?

its a wet clutch on the 50 series and later. I think its same for 1500. If I were you, I would go to messicks website and request a pdf download of the HST parts for your 1500 and you will see what I mean.

The 00's such as my BX2200 have a clutch pack that made up of friction disks and metal disks. When you turn the PTO on, pressure goes to a piston that pushes the friction disks and the metal disks together. There is a relief for that circuit...and the relieved oil goes on to feed the axial piston pump that your foot pedal works for traveling around.

Hope this helps. A similar clutch is used in many motorcycles, but it is ofter a dry clutch, springs press them together instead of a hydraulic piston, and when you work the motorcycle hand lever, you release the spring pressure from the pack. When you let the clutch back out, you press the frictions disks against the metal disks.

Frequently, the purpose of using a clutch pack made up of multiple disks is so you can have a strong clutch that is easy to work with low operator input force, important on a motorcycle, and important on the Kubota because that hydraulic pressure is not that high, and the pto torque could be pretty high sometimes.

I like my Kubota PTO setup.
