How does hydraulics work on a tractor

I hope this article inspires you to research more of what you can do with the physics of fluid. Basic Hydraulic Principles The 3 Most basic principles behind hydraulics are: 1. Liquids are incompressible 2.

Liquids transmit pressure in all directions and with equal force at right angles to all surfaces 3. Liquids under pressure follow the path of least resistance Some Hydraulic Terms to Know Pressure: Is the resistance to flow normally created by a load. Basic Components of a Hydraulic System The basic components in a hydraulic system are: 1.

Piston or Motor The reservoir holds the fluid; in the case of our garden tractors, oil. How the Hydraulic System Works The hydraulic system begins with the reservoir. How a Hydraulic System Multiplies and Exerts Force Since liquids exert force equally in all directions we can multiply the force it gives by increasing the surface area in which we want the liquid to push against.

Applying Hydraulics to your Vintage Garden Tractor The engines in our beloved garden tractors have enough power to push hydraulic oil to 2, psi or more. Thank you for saving the tractors! Facebook Email Print Twitter Pinterest.

It is usually common knowledge for most people who use hydraulics, but it is good to give a reminder of just how dangerous hydraulics can be. First, you are going to want to drive your tractor around for a little while so that the engine can get warmed up as the fluid is going to be easier to flush if it is warm rather than cold.

Anything that can contaminate your fluid will settle at the bottom so when the tractor is running, those contaminants will mix with the fluid and thus make it easier to flush out. Get all your equipment ready. Then you are going to need to remove the drain plug and drain all the fluid. Next, you clean the screens, replace the filter and then put the plug back in. Let the engine run for around a minute and turn your steering wheel from side to side to make sure you have a full hydraulic function.

Changing the hydraulic fluid or oil in your tractor is pretty easy to do and it is very much like changing the oil in your car. Small force acting on small area can produce higher force on a surface of larger area. The basic components are:. Operation: The hydraulic pump draws up oil from the oil reservoir and sends it to the control valve under high pressure.

From the control valve, the oil goes to the hydraulic cylinder to operate the piston, which in turn, raises the lifting arms. The lifting arms are attached with implements. The hydr aulic pump is operated by suitable gears, connected with engine. There are two types of arrangements for storing hydraulic oil in the system:. It is separate from the transmission chamber. Hydraulic pump : There are several types of hydraulic pump, such as gear pump, plunger pump, vane pump, and screw pump.

Gear pump is widely used in tractors. Gear pump can flow a bigger amount of oil, compared to plunger pump. Hydraulic cylinder: It is a bigger size cylinder, fitted with a piston and a connecting rod. It is also called ram cylinder. The connecting rod transmits power from the piston to the lifting arms. Piston moves in the hydraulic cylinder and causes reciprocating motion in the cylinder.

The lifting arms are raised by the hydraulic pressure while raising the implement but it is lowered by its own weight. Hydraulic tank: Hydraulic tank is used for storing hydraulic oil for the system. In some tractors, transmission chamber itself works as a hydraulic tank and same oil is used for transmission system as well as hydraulic system.

In some tractors, separate tank is there for hydraulic oil. Control valve: Control valve is a type of valve, which controls the movement of hydraulic oil to have desired direction, magnitude and speed of lifting.

Thus the control valve is to perform three functions:. Oil filter: It is small filter, located at a convenient position in the passage of the oil.
