How narrow can you dig a trench? What is the narrowest bucket size?

Digging a narrow trench by hand can be extremely difficult and time consuming so using an Excavator might be a better option for you! If you know anything about excavators, you'll probably recognise a Digging Bucket. Digging Buckets are the standard attachment sold or rented out with excavators and can come in a variety of shapes and sizes - but what you want to know is How narrow can you dig a trench? and What is the narrowest bucket size? 

In short, the narrowest excavator bucket available is around 3 inches wide

There are a variety of Digging Buckets on the market nowadays and all have a preferred job. The Standard Digging Bucket will vary in size depending on the size of the excavator that you're using. For example, the following guide is the narrowest Standard Digging Bucket that will fit on each machine size range: 

  • 1.5 Ton / 3000 lbs Excavator = 6 Inches
  • 3 Ton / 6000 lbs Excavator = 9 Inches
  • 5 Ton / 11,000 lbs Excavator = 12 Inches
  • 8 Ton / 18,000 lbs Excavator = 12 Inches
  • 13 Ton / 30,000 lbs Excavator = 12 Inches
  • 20 Ton / 45,000 lbs Excavator= 18 Inches

This is just a guide - there are a few machines in each range that this won't apply to.

HOWEVER, in recent years, the Micro Trenching Bucket / Deep Dig Bucket has been manufactured. This bucket is a design that you may not have seen before...it is much longer and narrower than your Standard Digging Bucket and can vary from 3 inches to 6 inches wide.
