TSC in my area has their CountyLine Multi-fit post hole digger power unit, Stk. No. 2100220 for compact cat. 1 & 2 on sale for $50 off. I don't dig many holes so I figured it fits my needs at a reasonable price. My Kubota
B2920 is 29HP, and approx. 21HP at PTO. I live on gumbo clay, no rocks, here in Texas, and am thinking the 9" auger would best fit my needs. Any experience with this unit, and or anyone using one of these? On a
B2920 enough tractor for 9"? Comments, opinions? Thanks in advance for your input.
I am fairly sure that those are in fact made by Speeco.
I had one for a while, but didn't use it enough to keep it.
That price seems high, it has been down to $350 this year in New Hampshire.
Hmmm, if you don't drill that many holes buying it JUST BECAUSE it is $50 off may not make much sense - but, your money, your choice (-:
Unless you are sinking Sono tubes I think you will find 9 inches to be one heckuva big hole, 6 inches is probably more generally useful for... errrr, lets see... POSTS, yeah.
Yes your tractor can almost certainly handle it, but the bigger the hole the more you have to back fill afterwards and the looser the post is until everything settles - and it settles more.
Bigger augers can get stuck more easily too.
ONE thing with PhDs is that you don't have to run them at 540, I doubt that I ran mine much over 200 (engine idle + a bit).
ANOTHER is that you don't want to let them screw into the ground, i.e. don't just push your position control all the way forward and wait for the auger to disappear into the ground.
"Allow" the auger to go down a few inches - and bring up soil - then "allow" it to go down a bit more - and bring up soil, etc.
