How to choose best trencher?

Trenchers can get the job done much faster and easier than a mini digger or traditional digger. They are cheaper to buy, or rent and whether you choose a walk-behind or ride-on, they can speed up the process of digging trenches dramatically. 

But what should you look for when it comes to choosing the best trencher?

Well we've got a few factors we recommend looking at. If you want to learn how to use a trencher then be sure to checkout this article

  • Depth

The most important in most use cases is the depth of the dig. Most units support up to 600mm or 60cm for simplicity. This means you can usually alter the depth with various heights up to this figure, such as 25cm, 45cm etc. 

Some models don't go down as deep as 60cm so check what you'll be using today and in the future for your trenches. You wouldn't want to limit yourself for future work. 

Different users will have different requirements for depth so check this.

  • Price

Probably the biggest factor when choosing the best trencher is the price, and there is vastly different prices. Commercial grade equipment could set you back up to $100,000, whereas smaller units for small commercial jobs or backyards may only cost $2,800 - $5,000. 

You definitely don't need to spend big money for a few small projects, and you may even find it's cheaper and more cost effective to rent your equipment from hire providers. 

Factor in delivery fees as these units aren't light and will require long haul freight which can add up to $250-$500 on top of your product cost. 

Additionally factor in maintenance costs, how easy it is to get hold of parts, is there any warranty offered, how much fuel is required etc.
