INTRODUCTION
Thank you for purchasing a new TerraBlade.
The purpose of this Operator’s Manual is to comprehensively explain to the operator how to set up, use and
maintain the machine.
It is important that the operator reads this manual carefully to correctly set up, use and maintain the machine
safely. It is essential that the Warnings and Cautions section has been read carefully.
The Claydon TerraBlade will give many years of excellent service with little maintenance due to its robust
construction and its small number of moving parts. However, for optimum machine life, some maintenance
will be necessary.
We reserve the right to make modications to the machine that could make some diagrams and descriptions
in this manual ‘out of date’. While the clarity of the manual should not be affected by this, please bring any
concerns to the attention of Claydon Yield-O-Meter Ltd for us to resolve the problem.
For any further assistance or explanation, please contact Claydon Yield-O-Meter using the contact details on
the front cover.The serial number on the data plate will also need to be quoted.
The Claydon TerraBlade has been designed to eradicate weeds between the rows / bands sown with a
Claydon drill.This is achieved by cutting weeds off at the growing crown just below the surface between the
sown bands in a growing crop. For best results, this is carried out in spring when the crop is rapidly growing.
The benets of the crop having rapid growth and ground cover at this time of year, in both winter and spring
crops, ensures any small weeds germinating are smothered and suppressed by the growing crop. Removing
weed competition helps the crop achieve its maximum yield by having more nutrients and moisture available
and being able to harvest more sunlight ensures the crop reaches its full potential. Removing weeds also
reduces their seed return, particularly important when resistant weeds are more common.

OPERATION
MACHINE OVERVIEW
The hydraulically folding Claydon TerraBlade consists of a centre chassis with hydraulic folding wings. The
machine width will determine the widths of the 2 blade bars. These are simply xed, using 4 pins, onto the
folding wings.
The machine can be mounted on the front linkage of the tractor, for manual steering guidance operations, or
the blade bars and depth wheels can be rotated for rear linkage mounting on the tractor. This is the preferred
option when used with a suitable RTK guidance system or with a camera guidance system. In both cases the
TerraBlade is connected to the ISO standard CAT II 3-point linkage.

TERRABLADE
OPERATION
HYDRAULICS AND FOLDING
The TerraBlade hydraulics consist of one double-acting ram, with a double-acting pilot operated check valve
to stop unintentional unfolding of the machine in transport.This also locks the machine in work.
The TerraBlade will require one double-acting hydraulic service to fold the machine from the tractor. The
folding and unfolding hose is distinguished by cable ties.
Folding and unfolding the machine is carried out with the 3-point linkage fully raised, using the tractor spool
valve. Connect the fold and unfold 1/2” ISO connectors (1 & 2) to the tractor.
Before operating the folding mechanism, please ensure there is room to unfold/fold up and, most importantly,
nobody is within the operational zone.

Tip: please ensure the lower link arms are centralised and xed to ensure the TerraBlade does not wander
off track.

TERRABLADE
OPERATION
FIELD GUIDE
The TerraBlade is designed to remove weeds between the sown bands in any crop established, winter or
spring, by a Claydon Drill, but will also work with other strip/row drilled crops.The best time of operation
is when the crop is actively growing, and the weeds are small. It can be used in the autumn, but often better
results are obtained in the spring with winter sown crops.This is because, when the crop starts to rapidly
grow away, it will give the ultimate competition, the surface being dry to effectively scalp the weeds that grow
between the bands.The best results are obtained when followed by a couple of dry days, reducing the risk of
transplanting small plants.
For the best results the TerraBlade width should be matched to the drill width, and follow in the same
tracks as the drill.This avoids problems with operational misalignment. However the end blade should always
overlap, and in some circumstances, may damage the end row of the adjacent drilling. In testing the wing of
the outer blade was reduced on the outer side to help reduce this problem.
Speed is important, depending on soil type, level of stones, down pressure of blades, as well as operational
guidance, which will determine the forward speed, typically 5-10kph works well.A Hoe travelling too fast will
bounce and be less effective, potentially missing the targets. The soil should be rm/dry enough to shear the
weeds off. Most crops are safe to hoe up to rapid stem extension (wheat Gs 32) with little or no damage.
Tip: during testing, it was observed that good tyres on the tractor resulted in less damage to the crops than
worn ones. Combined with dry soil conditions and fast crop growth, the wheel marks will quickly dissipate.

TERRABLADE
OPERATION
SETTING THE BLADE WORKING DEPTH
The TerraBlade has been designed to scalp weeds at the growing crowns.This requires the blade to dig into
the ground 2cm to effectively kill weeds.This 2cm working depth is achieved by the inclination of the blade,
the blade angle setting the working depth.The blades will run parallel to the ground.
The blade inclination indicated by the red line will “ski” the blade to the surface, the blade will not dig into
the ground but bounce across the surface.
The blade inclination above is too great trying to dig into the ground. It will continue to the depth where the
blade levels out.This could easily be too deep, causing too much soil movement, irregular depth, and uproot
plants, which could regrow. Getting the blade to “ski” at the right depth is crucial.This, combined with the
right pressure to hold the blade in position, will give the desired result.
THIS MACHINE SHOULD ONLY BE USED WITH THE LINKAGE SET IN
FLOAT POSITION

OPERATORS MANUAL - TERRABLADE15
TERRABLADE
OPERATION
SETTING THE BLADE WORKING DEPTH
345mm
At a height of 345mm, the hoe will be set neutral at ground level and ski the surface.To lower the blade bar,
shorten the top link, or move the front pin to the lower hole, thus giving the blade more inclination to work
deeper. The top link is the ne adjustment and the front hole is the coarse adjustment. The depth wheel
setting should remain the same once the machine has been set.
345mm 325mm
This correct angle is achieved by setting the front blade bar to a specied height. To achieve, this put the front
linkage into oat and allow the machine to drop its weight onto the depth wheels, then adjust the top link so
the chassis link pins are vertical. Finally, adjust the front depth wheels, to achieve 345mm to the base of the
blade bar.

16
TERRABLADE
Increase the pressure to the next level by moving the pin setting as seen below, rotating the whole frame
down and increasing the pressure holding the blade into work. In wetter conditions, the blade pressure can
be reduced by changing the pin setting.
Changes the working depth
of the blade. Increases pressure of the blade
slightly.
The blades will require more pressure when the ground is hard; if too little pressure is put on them then they
will not dig into the soil. Instead, they will skip over the surface and not cut the crown of the weed.
In wet weather,the blades require less pressure.If too much pressure is put on them they will dig in aggressively.
This will cause the blade to uproot the weed without cutting and not kill the weed.
It is very important to set the depth of the blade to scalp the grass weeds off at the crown.Too high and it
will cut the leaves off and the plant will regrow.Too deep and the plant can be transplanted, thus regrowing.
The target depth is approximately 2cms but can vary a little depending on the weeds.
The blade pressure and depth can be nely adjusted using the top link when front mounted. Shortening the
top link increases the pressure on the blades.It also changes the angle/ digging to increase the depth the blade
penetrates the soil surface.

OPERATION
DRIVING THE TERRABLADE
The TerraBlade can be front or rear-mounted. With the option of manual steering, it is relatively easy to drive
on the front linkage using the tractor steering to steer theTerraBlade, pushing it along and watching the blades
between the rows.
If you are trying to use auto-steer on the tractor, the TerraBlade can overreact on the front linkage. Moving
the GPS dome and mounting it on the TerraBlade could give better results. However, with this application it is
probably better to change the hoe, reversing the blade bars, and rear mounting it, enabling it to be towed for
auto-steer applications. Depending on the accuracy of the system, it may also require the addition of a camera/
eye combined with a side shift linkage steering system for precise row following.

MAINTENANCE
SCHEDULE
Your machine will require maintenance before and after use. Prior to using the machine, check for broken
blades or hydraulic uid leaks. Ensure all bolts are re-tightened after the rst eight hours of use.
The only lubrication that is required is for the ram, the location of these grease nipples is shown below.
MAINTENANCE
LUBRICATION
The recommended lubrication to use is EPT-1 or EPT-2 grease.
MAINTENANCE
BUSHES
The bushes on the TerraBlade are polytetrauoroethylene-coated. This material is dry-working and must
remain dry to operate effectively. Please do not power wash the area around the pins as this will cause them
to seize.
The expected life of these bushes is 7000 hours of working time therefore, should not need to be replaced
or maintained for many years.
