Power Of The Front Pakker In Action

Adopting a new front mounted
clod crushing and soil rolling system has markedly reduced the
cost of seedbed preparation for a Perth farmer by enabling him
to increase output by up to 40 per cent and reduce fuel consumption
by up to 20 per cent.
It has also cut down on the
number of machines involved and reduced the hassle of swapping
tractors, machines and wheels around to suit different soil
conditions.
Andrew Stirrat farms 310 hectares
of mainly cereals at Elcho, Rhynd, Perth. Last September, in
a move to create more level, firmer seedbeds for quicker crop
establishment and reduced slug activity, he purchased an OPICO
Front Pakker from local dealers, Earnvale Tractors.
Designed to work directly on
ploughed land, the Front Pakker has a working width of three
metres and employs a ShattaBoard spring levelling board to work
the soil in front of the 900mm press rings. A connecting rod
system harnesses the combined strength of all the springboards
to improve levelling, while the boards themselves cultivate
and consolidate.
A double-acting hydraulic ram
allows the operator to adjust the angle of the springboards
while in work, and lift the springboards out of work if necessary.
Last autumn, Mr Stirrat used
the front-mounted Front Pakker and rear-mounted one-pass Lely
45 power harrow, complete with three-metre disc drill on 190ha
of wheat, barley and rape, on soils ranging from heavy clay
through medium ground up to light stony land.
DELIGHTED
The results delighted him.
"In the past, we were using a Kverneland front mounted
power harrow in front of the one pass power harrow/drill on
the clay to achieve a fine seedbed and used a cultivator or
a press on the light land. Now, unless we need a really fine
seedbed, the front power harrow will stay in the shed!
The Front Pakker is equally
at home on the clay as it is on the stones. It makes a tremendous
job."
Slug activity, too, has been
reduced. Mr Stirrat's experience last autumn couldn't be in
greater contrast to previous years. "To start with, it
was drier, but as we aim to drill as early as we can to enable
the crops to get off to the best possible start, this clashes
with potato harvesting done in conjunction with a neighbour.
In the past, this has been a nuisance as tractors and often
wheels were swapped round to get the drilling combination right.
LIGHTER
"All the drilling can
now be done with a four-cylinder John Deere 6410 tractor - rather
than a six-cylinder 6610 - which is lighter and has better fuel
consumption. But, more importantly, it frees up bigger tractors
to cultivate stubbles or plough.
A lot of the time we were operating
at speeds up to 9kph," he added. " You can go at any
speed down hill, nut it's the tractor power and grip that govern
your speed uphill. This is where the Front Pakker is excellent
as it has a very low rolling resistance, making it easy to push
uphill. You often don't know it's there.
Best results were achieved
if the plough had two or three days drying in front, allowing
the top to dry out which in turn lets the boards work much more
efficiently.
As a rough estimate I reckon
we could cut seed rates by at least 30 seeds/m."
