* We have extensions to go down 2 metres but they require the auger to be removed from the post hole digger for each hole. If you need the extra depth – hire an excavator post hole digger, fit the auger and extension and sit and let the machine do all the work.
Choosing an auger for the post hole digger:
The auger should bigger than the posts so you can ram the soil back in. Or, a size smaller so you can hit the posts in for a snug fit. An auger which is “just right” will see the posts wobble after a short period and you’ll be grumpy with us.
What about a 2 person post hole digger?
Due to these being the style of post hole digger that everyone thinks of, it’s what everyone asks for..
But, the good units from Stihl are no longer available because we reckon someone at Stihl hired one and realised how horrible they were to use. They buck and kick and any of our staff who have used on never use one a second time.
So, we reccomend one of the hydraulic one man wheeled post hole diggers. Or even better, a drivable mini loader unit that’ll cost you a bit more but get the job done much quicker and mean you won’t have a sore back the next day.
