Digging Post Holes in Arizona Caliche with the Holey-Moley Digger

Utilizing the Holey-Moley Vacuum Assisted Post Hole Digger for excavating post holes in Arizona.

Digging post holes in Arizona presents a unique challenge, especially when encountering the tough caliche layer. Moreover, hiring a contractor for this task can be prohibitively expensive, often exceeding $100 per hole—if you can even find one willing to undertake the job. However, one Arizona landowner found a solution by purchasing the Holey-Moley Vacuum Assisted Post Hole Digger from Cat 6 Tools. This innovative tool allowed the landowner to efficiently dig all 55 holes and more, with the digger head still in excellent condition. The dowel pins were also easily sharpened whenever necessary.

Spread over 55 holes, the cost per hole amounted to just a little over $16, representing significant savings over the cost of having a contractor do the job.

The owners of the Holey-Moley Digger faced a third task: installing a short propane gas line. When faced with a contractor’s quote of an additional $1,200 just for excavating a 10-foot trench, they sought a cost-effective alternative. Utilizing the digger, they strategically excavated a series of post holes and then effortlessly collapsed the intervening soil. This innovative approach allowed them to use a vacuum to remove the dirt from the trench efficiently. This smart strategy not only achieved their goal but also justified the purchase of the digger with the savings from this single project.
