Dig Deeper Into Your Digging Systems, Part II
What to look for in digging system components.

Keeping Your Fleet's Hydraulic Systems Running Properly
If your machine's hydraulic system isn't working, neither are you. Here are some common causes of hydraulic system breakdown and steps you can take to avoid them.

Dig Deeper Into Your Digging Systems
A properly maintained digging system is essential to trencher performance.

Time For Your Spring Checkup
Spring is a great time to prepare your Ditch Witch equipment for the upcoming busy season. A little attention now can help you be ready when those landscaping, trenching, plowing, and drilling jobs start coming in.

Chain Of Events
The efficiency of any machine depends on the efficiency of each of its parts. In the case of digging systems, one defective part—a stripped bolt, worn tooth or inferior sprocket— can mean the failure of the entire system.

Trencher Maintenance
Proper maintenance is essential to keep trencher units operating efficiently. Performing routine maintenance and repairing minor problems as soon as they are identified reduce the chance of breakdowns in the field, and an effective maintenance program extends equipment life and protects the value of equipment.

Trencher Safety
Today, as it has always been, safety is a personal choice that each person must choose. We make that personal choice every day, even as we drive to work, when we choose whether or not to obey speed limits. Proper operating procedures, like speed limits, are put into place to protect not only the operator, but everyone that may be around from co-workers to bystanders.

Winterizing Article
Take the time to winterize your equipment this year. A few minutes spent could save you time and money in the months to come. The amount of winter care your equipment needs depends both on the climate and how it is used.

Selecting The Right Trencher
Trenchless procedures are best suited for jobs where surface improvements, existing underground utilities, and restoration costs make excavation impractical or impossible. But because many utility construction projects continue to be in open country where these factors are not issues, trenching often is the most efficient and cost-effective method of installing underground cable and pipe.
