Post Knocker

[fred]

Anyone use one ?

Have a fair bit of stock fencing to do but would also like to use it on normal 6' posts (featheredge), are they accurate enough to get plumb/level ?

Manual or on a digger
Manual is easier to get plumb as you go at first machine takes a bit more practice
As for square you need a f shape metal bar the main part atleast 4ft long and the f part to fit around the post you want to square up
Knock the post in a foot or so then use the f bar to twist it straight as you go

If you want to do strainers you need a big weight and really needs to be on a 3.5t plus machine for 6inch posts a much smaller weight will do

What hitch are you on Fred? I have a Protech. Great on stock fencing but you really need someone with you to speed things up. Not sure I would recommend on garden fencing!

I use one on 5x3 posts for sawn post and rail, with F bar as mentioned. Works OK as you can chop the rail off straight down the middle of the post with the depth guage set just right on a battery circular saw, so spacing not 100% critical.

I can't see it working well for longer square posts, especially with rails in the mortices as you come down. Hit a stone and it throws you off, it'll be enough to pinch a rail tight and force the post pissed. Quicker to auger in my book.

That said, I do know a few boys who make a nice job hammering in rustic chestnut cleft fencing with them. Key word here is rustic- dead plumb and level are not critical. I've never dared, as the top mortice on cleft chestnut posts is only a couple of inches off the top of the post and we all know how well chestnut splits! Surprised it works to be honest, auger for me every time.

I suppose it depends quite a bit on the soil type you are working on. Round here even post need to be put in with the rock spike first in some areas.

done a few miles of 5x3 8ft long posts with a tractor mounted one needs 3 men on it really to make it work one driving one on the controls and the third on the twist stick and holding the posts to start with. we where knocking roughly 90 a day then spending a hour or so setting out posts for the next day

Did some with a local guy who had a knocker mounted on his 8t jcb. We did a fair distance on his fields once posts were laid out.
