Power Post Performance | National Geographic

contender number two Ross Martin and the
power post driver the power post driver
is an air tool that drives T posts and
oil pipe into all sorts of terrain Ross
is bringing the Thunder from Down Under
a compressed air powered post driver
from Marchant engineering it packs a lot
of power into a small package he’ll post
driver is a 40-pound tool with a force
of a 90 pound jackhammer it’s strong
enough to drive steel posts in the
limestone can be used in all sorts of
conditions the power post driver can
even operate underwater here’s how it
works a gas powered air compressor sends
pressure through a hose to the post
driver inside the distribution valve
cylinder piston and striking hammer
firing unison 1200 blows per minute the
actual piston Y is 2.2 pounds and it has
in force strong enough to break rock and
that’s why the power post driver is
unbeatable so the world of post driving
is about to get a wake-up call it’s this
thing the power post driver you got it
how is it revolutionising post driving
well what would you think if I could
just take this T post and drive it in
this ground in under 10 seconds that’s
pretty hard ground I want to see that
let’s show you okay
all right that was effortless and you
didn’t even break it so fat no the
ground here is packed dirt sand gravel
feels like concrete
this is compacted Road dice this is Road
base that’s all right
so how much experience does it take to
operate this thing well we set up a
little test on the proving ground today
we have Trevor an experienced fencing
contractor 40 years competing against
Murray a housewife with no experience
Murray’s got the power post driver
Trevor’s got the old manual model who’s
gonna get a post into the ground first
get ready set go
Marie’s whipping Trevor’s buck with that
power post driver he’s gonna have a lot
of explaining to do next time he sees
his pals
Murray wins Murray with a power post
driver has beaten Trevor hands down in
really hard ground
