A hydraulic system works by moving the working fluid through the components. But apart from power transmission, a hydraulic fluid additionally helps in dissipating the heat from the components thus cooling the system. The heat generated is due to the working of various components. To ensure smooth functioning, the moving components of the system should be lubricated as well. Thus, hydraulic fluid has various functions in a hydraulic power system.

The selection of hydraulic fluid is dependent on the requirements of the power system. Nonetheless, the hydraulic fluid must possess some properties to be used in a hydraulic power system. A hydraulic fluid having good lubricity separates and lubricates the components effectively. A good hydraulic fluid should have ideal viscosity, it should be stable chemically, as well as physically to ensure usage for long time periods. The fluid must have high bulk modulus for proper working. Another property desired in a hydraulic fluid is fire-resistance. Additionally, hydraulic fluids having low foaming tendency are preferred in hydraulic systems.

Although no hydraulic fluid can possess all the properties. Hence, the best possible hydraulic fluid is used which fulfils most of the requirements of the system.

This video is an interview with an agronomist exploring the role and responsibilities that come with it.

If a disease outbreak takes hold of a certain crop or livestock species, what does that mean to a society so dependent on agriculture. What are some of the ways to prepare and respond to these events? To answer these questions, the Office of the Vice President for Research at Colorado State University gained insight from researchers across multiple disciplines related to agricultural biosecurity.

If you're a total tractor "newbie", you'll hear the term PTO or "Power Take Off" used often when talking about tractors. It's one of the most dangerous parts of any farm tractor and something that needs to be respected by the operator. In this video we discuss the different types of PTO and how they work.

The PTO is the spinning shaft on the back of the tractor that attaches to a shaft to power a variety of implements, brush hogs, finish mowers, tillers and most post hole diggers.
PTO's haven't been redesigned since early farm tractors, it's a splined shaft that spins, turning a long driveshaft that leads to a gearbox to make blades spin, tines turn, or augers dig.

Problem is, if you get any part of your body parts, hair or clothing stuck in a spinning PTO, you'll likely be killed in a horrific manner, or maimed for life. Don't want to scare you here, but NEVER get off the tractor and go back near a spinning PTO. EVER!!!!

PTO entanglement one of the reasons why farming is either the most dangerous, or second most dangerous occupation , and especially if you're new to tractors you need to stay way from them with the tractor running. A human can't stop a PTO from turning.

Episode 3 of SARE’s “What is Sustainable Agriculture” video series provides an animated outline of the basic principles of conservation tillage. This is a basic explanation of conservation tillage and its benefits in agriculture.

What is Vertical and Horizontal Movement?

Every pitch in baseball has what's called Vertical and Horizontal movement as it approaches the plate. Vertical and Horizontal movement is defined as the magnitude of “break” a pitch has, either up or down (vertical), or laterally (horizontal). Essentially, both movements indicate the pitch's trajectory deviating from a straight line as it crosses the plate.

Vertical and Horizontal movement is measured in inches and can be recorded through ball tracking technology like Trackman, Rapsodo, Hawkeye, and PITCHf/x. It’s important to note that these technologies can track movement in different ways.
