A kiwi who makes post drivers told me it has an awful lot to do with the speed of the drop in the last meter. Obviously a big hammer helps though.

I run a protech p300s. Delighted with it. Done everything I ask of it. Rock spike has been a great investment too.

We bought a wrag basic xl with a 300kg weight and rockspike. The slew is really handy for getting into corners or reaching over ditches. Does everything we need it to so far.

Hmm, I've broken one on mine already. Are they easy to replace?
Yea reasonably as I've done 3 on mine, take the plate off grind back the weld and punch the old one out and weld in a new one.
Yes you can get the hammer 4 metres high.
I’ve not snapped any in the p400s but I’ve done a set in the evo1 tracked machine. We put 2 extra spikes in each machine to give you more choices for positioning the post in the bash plate. I just make the spikes from bolts on the bench grinder and weld them in, easy job.

Mate had a new cap for his evo (protech) couple week ago and spikes have all gone already through continually rock spiking in some stupidly hard ground.
What side is the rock spike on?
They seem to usually be fitted to side you stand at - does it not get in the way when you are not using it?

Yes its a right pain in the arse.
Why is it not put on the other side then?

Spike on the P500 is on front
I think main reason for them being where they are is safety. Don’t want to be under hammer to position it, although you do get option of which side. When driving in posts I remove rock spike, simples

All this talk of post drivers...
I used a Wragg mast and made the rest myself.
90 degreee slew, plus 600mm of telescope on main frame.
Hard to tell from these pics though it will work at the side fo the tractor running down a fence, fold up to 8ft wide and allow to tow a trailer behind.
Extended rearwards it will reach about 10 foot from the tractor tyres
Only a 200KG weight which is a bit light when driving the thick end of telgrapgh poles in, so if i did it again id go for a heavier weight.

On the lookout for a used post knocker, spoke to a local contractor who runs a Protech with 300kg weight and rock-spike who says he only got beat once trying to put strainers into what looked like crushed rock, so looking for something similar. Called Wrag today but they've no used models, Protech don't seem to answer or return their phones or mails.
Anybody know of one, can't justify a new one, as only fence part time to fill in a gap when other work is quiet.
Cheers
