Advice for using a gas powered post hole auger
I've been trying to put up a t post fence for a garden and a puppy play area. Unfortunately, I am still having complications from emergency surgeries that took place almost a year ago that leave me weak and easily fatigued. Plus, I'm a 61 year old short widow. I've been using one of those manual post hole drivers that slide over the top of the t post and a digging bar, but it's been very slow going. And I just found out that I will need another surgery in about 3 weeks. I desperately want to have this fence up before then. I just found out that my local Ace Hardware rents gas powered 1 man auger. I've been able to look at it and pick it up and I think that I can handle it. Yeah! It costs around $100 for a 24 hour rental so I'd like to get all of the holes dug in one day. I am going to clear the fence line of leaves and such and mark every 5 feet where I want a post to be so that when I've got the auger I can just go down the line digging holes. I'm not even going to worry about putting the actual posts in as I move along.
Aside from clearing and marking the fence line, is there anything else that I should prepare ahead of time? I would also appreciate any tips or tricks for using the auger?
