Questions

About the PHD18

Does this come with an auger?

No. The photographs on this page show the digger fitted with an auger for illustration, but the auger is sold separately and is not included with this listing. Choose an auger to suit your post size and order it alongside the digger.

What size tractor do I need?

A minimum of 18 HP with a 3-point hitch and PTO.

How deep will it dig, and what auger sizes fit?

We are confirming the maximum digging depth and the auger mounting size (hex or round, and shank diameter) with the manufacturer and will publish them here rather than estimate. Email us before you order an auger separately if you need this confirmed first.

What does the gearbox weigh?

We are confirming the shipping weight with the manufacturer and will publish it rather than estimate it.
