I've got to get an auger and some bits. I've been renting one with a 36" bit for planting trees.

I want to buy one with several bits.

What size bits do you use most?

what machines are you guys using to dig holes? bobcats? 36" bits are huge! Im not a huge landscaper, its my secondary function really, i do it only by special interest. Im looking to buy a garden tractor or something with a PTO that will run a auger on the back, yet even them most only offer 12" bits, id like to get something in the 18"-24" range to plant 3-5gallon pots.

Scott with you having a skidsteer I would get a 18", 24", 36" and maybe a 48" if they offer them that size for skidsteers.

If you get hooked up with some deck and fence contractors and can talk some business sense into them about subbing their holes out to you for a couple hundred instead of having a crew take a day to dig 40 or 50 holes then you can always rent the 9" and 12" bits.

If you have a Sunbelt rental store near you they have really cheap prices for renting bits on the 9" for my Dingo, it was only $7.15 out the door per day versus Capital rentals which is $24.10 for one day on the same size bit and insurance. I imagine that you already have the forks for your machine, if not then those are a must also.

Gilla, I don't think the A-19 Cat auger will turn a 48", but it's becoming pretty obvious that I'll need a 36" and might as well get a 24", 18" and 12" as well. Anything smaller than that and I can dig it with my Stihl hand auger.

Hopefully somebody who does ALOT of commercial plantings will chime in here with the most used sizes they have.

As far as I can remember I've only ever seen commercial guy's using 36" bits, anything smaller and they've got 5 guy's with shovels digging....

I have a Cat 257B for digging the larger ones. I also have a Stihl BT121C for the smaller holes.

Do any of you guys have problems breaking shear pins with those bigger augers?

We have an 18" and a 36" bit for our Vermeer mini-skid steer. It turns the 36" just fine, low speed high torque auger powerhead. The 18" works well for shrub planting, and 36" for B&B trees. The mini-skid with rubber tracks doesnt tear up stuff nearly as bad as the 773 on metal tracks, or even just rubber tires for that matter!
