I have been installing lots of in ground basketball goals recently and the big ones require a 16" diameter hole 4' deep. Good old fashion labor works fine but Im looking to upgrage. Are there any 2 man power augers that will take a 16" bit? All the ones I find the max is 12". A dingo is to to much money to rent on days were I do less than 4 jobs. 99.9 percent of the time its in a location I can back the truck right up to it, are there any kind of truck mounted power augers?
