OPICO Front Linkage system has been designed and manufactured by HE-VA for over 19 years,
HE-VA has a large European market and also exports linkages to Canada, New Zealand and Japan and supply approx 1800 units a year.
We at OPICO have been supplying the front linkage system in the U.K for over 10 years.
Each new Front Linkage is
tailor made to the tractor and designed on CAD with computer systems and then laser cut out. All new Front Linkages are tried and tested in Europe before they are supplied in the UK.
Whatever front implement you
intend to use, OPICO have the ideal
Front Linkage for the job with lift
capacities from 1.5 to 5.5 tons.
What's more, OPICO have a Front Linkage
to suit every tractor, with over 800 different
models available.
All OPICO linkages incorporate
the Vertical Fold System (VFS) allowing the link
arms to fold fully back when not in use improving
manoeuvrability and safety.
Top link and balls in
storage position. (VFS)
Vertical Fold System
allows the linkage arms
to fold behind the front
of the linkage when not
in use.
Maximum lift capacity
Lift capacity is rated at the hook and ball end. Cat II quick release linkage hooks on 1.5, 2.5 and 3.6 ton linkages. Cat III linkage hooks on 5.5 ton linkage. Distance between linkarms (balls) is 825mm.
Quality that lasts
Ball joint and seals on lift
ram ends - ensures any
twisting force from a front
implement is not applied to
the rams, damaging seals
over time. Double acting
rams fitted as standard on
all sizes of linkages.
The linkage is painted the same colour as your tractors chassis with
a two-component primer
and topcoat to give the
best possible finish, so the front linkage looks like a intregral part of the tractor.
VFS Arm positions
The simple eccentric pin system
allows the operator to set the linkage
for the job in hand. In use, the
operator has the choice of three
different positions, fixed, semifloating
using the eccentric pin or
fully floating without the pin.
When not in use the link arms can be
put into transport position using the
Vertical Fold System (VFS), by
placing the pin under the arm and
retracting the lift rams completely.
Fixed arm position
In the fixed arm position the arms
cannot move independently, this
ensures a constant working height
and level set by the hydraulic rams.
Semi floating
arm position
Independent link
arm movement
50mm at ball end.
Fully floating
arm position
Free independent
movement at
ball end.
Transport position
Transport position
ensures the linkage is as
close to the tractor as
possible during
transport.
Quick and easy fitting
Fitting is simple and quick,
as the whole side plate can
be removed. Also on most
models, the linkage bolts
onto the front of the tractor
as well as the side.
The front linkage side plates
are designed to match the
individual tractor model
and provide support suitable
for all lift capacities
giving more secure fixing to
the tractor.
OPICO hydraulics
Selector valves
Most OPICO linkages come equipped with
hydraulic (selector) shut off valves as
standard. The valve handle is located
close to the cab rear window, in most
cases, for easy access from the tractor
seat. The shut off valves allow the user to
lock off the linkage in a fixed position and
use the hydraulic service for another
operation.
Hydraulic connection
Where possible OPICO linkages use a
"Banjo" fitting to tee into the tractor
hydraulic system so that the user never
needs to disconnect the linkage hydraulic
hoses from the tractor. If the user needs
the outlet back, the shut off valves can be
closed and the rear quick coupling
becomes available again for another
connection.
Replaceable bushes
Solid half-shaft link
arm mounting with
replaceable link arm
bushes and bush holder.
Designed for the larger end of the amenity tractors and the smaller end of the agricultural tractors, PTO is also an option for most makes and models of tractor.
Made from 40mm steel the 5.5 ton is heavy in build and practical in use. The link arm ends are CAT III as standard as is the Top Link. The 5.5 ton linkage has a different VFS arm postion system to the 3.6 ton due to its size and strength.
Like the 3.6ton, 4 arm positions are still attainable making the heavier linkage just as versatile as the lighter ones.
*PTO and single accumulator not included as standard
The PTO gearbox is connected to the tractor crankshaft
pulley by means of a rubber damper preventing vibration.
Similarly the "soft start system" uses an electro-hydraulic
multi-plate clutch inside the gearbox to provide smooth
power engagement to the front PTO. Oil pressure for the
clutch is supplied by an integrated pump in the gearbox
which is driven by the input shaft.
Where possible OPICO use the tractor manufacturer's
own PTO engagement switch so that it integrates neatly
into the switch layout in the cab.
OPICO PTO units are completely self-contained using
standard transmission oil and a replaceable oil filter.
The front PTO gearbox works at 1000 PTO rpm and
it turns anti-clockwise when you look at the front of
the tractor.
The shaft is 13/8" (35mm) with 6 splines DIN 9611.
The 'heavy duty' gearbox can transfer a maximum of 125
kW (173 hp) continuously and even more in peak loads.

The HD Buckrake/Snow Ploughing linkage has been
specially developed for situations where the operation causes high stress levels and sideways forces to be excerted on the

Universal Front Linkage
The Universal linkage incorporates all the standard features of 2.5 to 5.5 ton linkages but is
manufactured without full length side plates.
This multi-purpose linkage has short side plates with multiple attachment holes so that it can be
adapted to fit various machines and tractors where a three point linkage is required, e.g. trailers,
slurry tankers & 4 wheel drive vehicles.
