Part three of the information series on hydraulic systems. Today’s topic is hose.

If the pump is the heart of the hydraulic system, the hoses are the blood vessels.  Hoses are not tricky to figure out, but it can sometimes be difficult to decide what kind of hose to get.  You’ll want to make sure that the hose you buy will comfortable tolerate both the constant pressure of fluid and the pulse force in some applications.  Agristore USA’s hoses will tolerate up to 4800 PSI of constant pressure but are not recommended for high pulse force applications. 

Another characteristic of hoses is the number of layers of wire reinforcement.  Agristore USA’s hoses are 2-wire allowing for increased PSI at the cost of some flexibility.  The 1-wire hoses are the most flexible but are generally rated at a lower PSI. 8-wire hoses can withstand intense pulse forces but are barely flexible.

The third thing to check is the temperature rating of the hose. Most hose, including Agristore USA’s, is rated for temperatures up to 100°C or 212°F. If your system is running hotter oil, make sure to get hose rated at 300°F or higher. To view our hydraulic hose listings, click here.

Part two of the informational series on hydraulic systems. Today’s topic is hydraulic pumps.

Hydraulic pumps, sometimes called hydraulic motors, are usually powered by a PTO connection from the back of a tractor. Some pumps dead end the PTO connection while others provide extensions to implements. When the power from the tractor is transferred from the PTO to the pump, it creates the driving force on the hydraulic fluid that allows it to move cylinders and attachments. Most tractor pumps operate in an open system, which means that the fluid behind the pump is kept at atmospheric pressure. The hydraulic fluid is exposed in some way to the air and the pump provides all of the necessary power to move the fluid.

Agristore USA offers the Hydraulic PTO Tractor Pump. The distinguishing features between the five different pumps are the implement end and the output ratio. You can get 1-3/8” male or female on the implement side and the ratios come in 1 : 3, 1 : 3.5 and 1 : 3.8. For Agristore USA’s PTO pumps, click here.

Today kicks off an informational series on hydraulic systems. I'm going to take you through one of the most important systems on a tractor step-by-step and explain each part along the way.

Let's start with the hydraulic fluid reservoir. It's basically an oil tank that allows a surplus of fluid to provide constant output throughout the system. Without the reservoir, the system could only store enough oil to go through once and any leakages would cause immediate interruptions in output.

The size of the tank will depend on the size and output of the hydraulic pump you need to power your attachments.

When ordering tiller blades, it's important to keep in mind that there are actually two different blades on a tiller: a right-hand blade and a left-hand blade. How do you know which is which?

Step 1: Remove the tiller blade from the tiller.

Step 2: Hold the tine so that it dangles from the bolt holes.

Step 3: Holding the blade in front of you, turn it so that the cutting edge faces you. If the blade curves to the left, it's a left-hand blade. If it curves to the right, it's a right-hand blade.

The blade pictured above is a left-hand blade.

Hydaulic Top Links make it easy to attach your 3-point implement and make adjustments directly from the driver’s seat, saving time and increasing productivity. 

Agristore USA currently stocks both Category 1, 2, and 3 hydraulic top link cylinders with standard double-piloted check valves.  These check valves are a safety feature designed to keep the cylinder locked in position and prevent drift.  The hydraulic top links we carry have British Standard Pipe (BSP) threads in the ports.  BSP is the standard pipe threading worldwide, with the exception of the United States, which uses primarily National Pipe Thread (NPT). Because of this, all of our hydraulic top link cylinders include two BSP to NPT adapters (3/8” male to male), unless the cylinder is purchased with our nesting Hydraulic Hose Kits, in which case no adapters are needed.  Please note that BSP to NPT adapters must be used when attaching a pre-existing NPT hose kit from your tractor to our hydraulic top links. 

Check out our online catalog at www.agristoreusa.com for more information on the hydraulic top link cylinders, hose kits, and adapters we carry.
