These are also very good knockers for diggers. I'd say the design is better than a Protech for excavator use. I've adapted by Protech to work like this. But they are slightly heavier. On a 5 ton plus machine id go vector over Protech. But probably a bit heavy for smaller machines without compromising on the hammer weight.

Kinghitter use a similar design but not sure who is there UK importer. They also the do not only the rock spike but also an auger all built into one setup.

The protec are towable behind a pickup. Is the Bryce on able to. Some of theirs look enormous the one with the out back operators seat

Price is £2770 for a p18 with a 180kg weight with a bracket to suit the machine.
On one hand that sounds reasonable but Jesus it's a lot of money for something that really is quite simple. I went to bid on a used p18 at a local auction and bidding started at my max bid, and finished at something like £2200+vat. That was a good few years ago now, ended up making my own and it cost less than a grand in parts and steel but took plenty of evenings in the workshop to build.

180kg will be absolutely fine and should deal with decent sized strainers. I've put in massive oak strainers and if it's hard ground I have augered 6" holes first. Rock spike is great, helps posts go in on the line and not slip sideways. Making holes with a rock spike also means you can easily jab a load of stakes in and they'll stay upright while you're back in the digger. I usually jab in 10 posts or so and then knock them in, way faster than a tractor.

Yes. Tried one on a customers machine but didn't get on at all. It's like the worst of both worlds. You have minimal control of alignment using the levers yet still have to rely on someone in the cab. It takes away from what makes digger mounted ones good

That’s exactly what I’ve bought, and I can see where @Storrsy and @JD450A are coming from with it being less convenient to use on your own.
However, I’ve been doing a few post replacements at a property where I keep some sheep and have chanced it on the 3 tonner. It is way too heavy for this digger, but with the leg down it actually handles it fine! Getting out and operating it from the side actually works really well - I’m happy with it.
It would/will also be very easy to simply run the hoses directly to the machine and operate from the joysticks - I might do this when using it on the 6 tonner it was purchased for.

Fair play on the TB230! The p220 is some lump, is that the 250kg hammer or 300kg? To be fair you wouldnt want to chance it without a leg- at least you can arrest yourself quickly with a leg if it all starts going south.
The trouble however would be if you wanted to knock 7ft or 8ft strainers you cant really get enough height under the hammer unless you extend the leg- but then you'd need to shorten the leg on the p18/220 because the short mast height would t allow it to be knocked to depth. That's what I found anyway when I used it with the leg.

How long are we giving the dipper this time before it twists!?
