PTO Gearboxes
PTO or Increase gear boxes are mainly applied to agricultural tractors where more hydraulic power is necessary than the program on the tractor can provide.
The quick release coupling upon the gear box attaches to the tractor PTO shaft and steps up the PTO speed to one much more suited to the efficient speed of a hydraulic pump. A Gear pump is suited to the other side of the gear box.
The Power Take-Off, mostly referred to by its acronym, PTO, is a common type of mechanical power delivery in the mobile machine market. The PTO is a way of transferring high power and torque from the engine (generally via the transmission) of trucks and tractors. In combination with gearboxes and pump mounts, almost any kind of mechanical power tranny is possible.
There are three common power take-away methods in the mobile machine market; tractor design, truck transmission design and engine crankshaft-driven, although the latter is not commonly known as a PTO. The crankshaft-driven approach to power transmission is often used for hydraulic pumps installed to the front of an on-highway pickup truck, like a plow/spreader or cement mixer. A little shaft with U-joints attaches to a yoke coupler to carefully turn the pump. This configuration of drive isn’t generally referred to as a PTO, however.
The tractor PTO dates back pretty much so far as tractors. Many early PTOs were powered from the transmitting, which being located behind the tractor, allows for easy location of an result shaft. The transmission kind of PTO is only engaged when the transmission clutch is also engaged, and is usually coupled directly to transmission, so that when the clutch is depressed, the PTO isn’t driven.

If the transmission is driving the wheels, then your transmission PTO is turning. This does mean the apply can backward-power the transmitting aswell when the clutch can be depressed, such as down a hill or if the attachment has a system with high rotational inertia, leading to surging of the drive wheels. This was avoided by the addition of a devoted overrunning clutch for the PTO, which prevents torque from being applied in the opposite direction.

A live PTO often uses a transmitting clutch with two stages. The first stage of the clutch works the driven portion of the transmitting, and the second stage of the clutch handles the engagement of the PTO. This technique allows independent control of the transmission, to ensure that the PTO maintains operation regardless of transmission clutch activity, which includes stopping of the tractor itself. For a tractor with a mower attachment, for instance, this is a minimum requirement; you can’t have the mower turn off when you feather the clutch up a hill and around a tree.
