Post hole digging tools?

A narrow spade will get you only so deep, the post digger you mention with two poles on it is what you need. The volume top be removed isn't the issue, its getting at it, loosening it up and removing it vertically that's going to be the issue.

 

I would go for a hand auger and a digging bar. The auger works well if there aren't too many large stones it will cope with anything smaller than 1/2 brick and the digging bar will chop through clay with ease - much easier than the two handled ones.

 

I would usually leave the old posts at ground level and start with say a three quarter panel so you can dig all new holes. The idea is to remove as little soil as possible around the new hole.

 

The item you refer to are called "Spoons" they are just used for removing the loose soil etc.
You need a "Grafter" the loosen up the soil first.

 

hard to find these days, most shops have "lazy *****" , but you need about 5 to get the job done

 

Hire sds breaker with clay spade, quick & easy to make square holes.

 

Do they work well? Worth the investment?

 

Yes if you have shale / heavy clay

 

This is only a tiddly breaker, dug out quite a few holes & trenches with a bigger electric & hydraulic breakers & clay spade.

 

Yes, sure if they do sds plus version, If your Titan is sds max then there plenty of choice.

Can't see any thing listed for sds plus, it's all sds max or hex shaft for clay spades.

 

Yes, with a bull point.

 

If you are breaking up old fence post foundations - a pair of safety specs, the stuff can fly around like bullets when it is chipped at

 

The Titan breaker - the big one - is a hex shank breaker. SDS bits wont fit in it.
