1. What size machine?
Perhaps the first consideration when choosing a mini digger is: How big should it be? The generic term 'mini' is applied to a huge array of machines, typically ranging in size from the smallest, at about 1 tone, to machines which weigh in at 10 tones. Verify the dimensions of the dig site carefully to be sure the mini spade you are hiring will match in.
2. How deep will you need to dig?
You want to look at how heavy the trenches or holes you intend to dig need to be and make certain that the digger version you hire has a long assortment of expansion to perform the job. Too short an arm, and you'll end up with trenches shallower than you'd planned for. 'Dig depth' is a, therefore, a key criterion when choosing a digger.
3. How wide do you need to dig?
The width of your trenches is another important factor you will need to consider, as bucket dimensions (i.e. the digging implement itself) vary tremendously in size.
With the ideal width bucket, you can be sure of digging precise trenches in continuous arcs. Too narrow a bucket will cause a messy attempt to carve out leftovers, even though a too-big bucket will leave you scuppered.
4. What height are you dumping at?
This is dependent upon your skip or dump truck, but you should be careful to make certain that your mini digger can reach high enough to ditch the excavated material. Consider the dig zone attentively and the possible position of the digger relative to the jump. If the latter is on higher ground, you might need to look at a larger digger.
