Adjusting Valves

Adjusting valves is a chore, but the results of your labor are well worth the trouble.


Replacing a Radiator

Calculate the heat-rejection capacity as well as the physical size of a radiator before installing a replacement.


Biodiesel Basics

You need to change filters when switching, but biodiesel is more efficient and burns cleaner.


A Diesel Primer: What to Ask for When Ordering Premium Fuel

Over 80 years after Caterpillar introduced the first diesel-powered tractor, the fuel is the essential fluid of any farm operation. Buying good fuel and understanding why it needs to be high quality is crucial now more than ever, due to advanced engine technologies with tighter tolerances. This fuel primer should help you negotiate buying high-quality diesel. To start with, there are three stages of diesel combustion that include:

  • Delay: This is at the end of compression and after the start of injection, when the fuel does not ignite immediately.


SCR components critical in modern diesel engines

In the Mid-February issue of Successful Farming,, I covered the basics of diesel exhaust fluid (DEF). I followed up with a brief overview of the components employed in a selective catalytic reduction (SCR) system.

Keep in mind that the SCR is only one part of the emission control system on a modern diesel engine. It can be fitted with a diesel particulate filter (DPF), diesel oxidation catalyst (DOC), exhaust gas recirculation (EGR), or all of these.
