Do not stand between the tractor and the machine.
Standing between tractor and the Harrow is especially
prohibited during coupling and uncoupling.
Retighten all nuts.
All nuts should be checked and retightened after a few
operating hours. Nuts may come loose due to machine
vibration.
Riding on the machine is prohibited.
Serious or fatal injury can occur as a result of riding on
the machine.
Proceed with care in the event of leaking hydraulic
fluid.
Defective hydraulic hoses or incorrectly seated
hydraulic couplings can trigger unpredictable machine
movements and cause injury.

3.0. Introduction
Thank you for your purchase of a new Claydon Straw Harrow. The Claydon Straw Harrow is a
fast and low cost operation which can be used numerous times to create a micro-tilth for fast
weed germination, hoeing out weeds, killing slugs and levelling out straw prior to drilling.
Using the Claydon Straw Harrow will result in a cost effective way of germinating weeds and
creating stale seedbeds.
The Claydon Straw Harrow will gather and carry some straw in its tines in the heavier patches,
and slowly release it out of the rear of the machine in a steady/even flow through the lighter
covered patches. By carrying a small amount of straw at each tine the Harrow acts like a
broom dragging along the ground. This broom effect destroys the delicate eggs by moving
and breaking them or exposing them to UV light at the surface.
Slugs tend to lay their eggs just below the straw layer in the dark damp atmosphere that suits
the eggs perfectly, and as a result are right next to a perfect food source (freshly germinated
seeds)when they hatch.
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. For any further assistance
or explanation please contact Claydon Yield-O-Meter using the contact details on the front
cover and quoting the serial number stamped on the left hand plate, near where the top link
attaches.

3.2. Warnings and Cautions
These warnings and cautions must be observed when operating the Straw Harrow.
Observing the warning signs and other notices will serve the operators safety.
Ensure total weight of tractor/Harrow combination does not exceed
permitted limits, and the weight of the tractor is sufficient for safe field and
road use.
Do not allow anyone to stand between the tractor and Harrow during
coupling/uncoupling procedures.
Ensure a safe distance from the machine is obeyed by spectators whilst the
machine is in work.
Pressurised hydraulic oil is dangerous, therefore connecting and
disconnecting of the Harrow must only be undertaken with the tractors engine
turned off and the pressure in the hoses released.
Before operating the machine ensure no-one is standing within range of its
turning.
Ensure all bolts are retightened after the first eight hours of use.
Do not work underneath suspended loads; ensure adequate props are
positioned before maintenance work is carried out, preventing the machine
falling under its own weight.
Take care not to trap body parts within moving or pivot points.
3.3. Equipment Overview
The terms ‘front’ ‘rear’ ‘left’ and ‘right’ in this manual refer to the machine as follows:
1. ‘Front’ indicated the three point linkage end of the machine.
2. ‘Rear’ indicates where the lights are mounted on the machine.
3. ‘Left’ indicated the left of the machine as you look at the machine from the rear.
4. ‘Right’ indicates the right of the machine as you look at the machine from the rear.

4.0. Connecting the Straw Harrow to the Tractor
The Claydon Straw Harrow mounts to the 3 point linkage of the tractor on CATIIIN linkage
pins, you will need to use the correct size balls (not supplied) to fit the pins. The hydraulic
service should be paired together for the tine angle adjustment rams (Figure 3).

The following label (Figure 4) can be found located on the front of the Straw Harrow, the
label specifies the corresponding hydraulic connection and there color coded indicators.

Figure 4: Label for hydraulic service
Once the Straw Harrow is attached and at the correct working height, the top link should be
set at an angle in which the convergence point between the upper and lower link arms
should fall at the front axle (Figure 5). This can be achieved by altering the top link pin
attachment points on the tractor and the Harrow. This ensures stability and the mass of the
implement is used correctly.

5.0. Straw Harrow Set-up
5.1. Set Machine Level
For optimal working, the Claydon Straw Harrow must be set level from front to rear on the top
link of the tractor. Failure to achieve this will result in the harrow blocking with straw in the
front if the top link is too short or in the back if the top link is too long. To confirm the Straw
Harrow has been set level, it is advised that whilst one person is operating the machine,
another person should ensure the harrow is set parallel to the ground.
5.2. Working Height
The Claydon Straw Harrow has no depth wheels and is designed to carry its own weight on
the tines. If you are finding that the Harrow is doing more work than you would like you can
carry some weight on the tractors three point linkage.
The tine angle can be altered for aggressiveness from the cab with the hydraulic rake angle
adjustment. For chopped OSR or Bean stubble the rake angle can be at maximum if so
required (this position is most aggressive and moves the most soil, Figure 6). However, on
chopped Wheat or Barley stubble the tines will need to be angled back to allow the straw to
flow through the machine without blocking up (Figure 6).
Aggressive Rake Angle –OSR or Beans
Shallow Rake Angle –Wheat or Barley
Figure 6: Example of different rake angles in various crops

3m - Straw Harrow
[9]
5.3. Field Use
For best results it is suggested that the Straw Harrow should be used at an angle of 30º to the
direction in which the field was harvested, this will ensure straw and chaff is level across the
field. If you are using a Claydon Drill after the harrowing operation it is advisable to travel in
the same direction as you are intending to drill.
Whilst in use the Harrow should be dragging a small amount of straw along the ground and
slowly distributing it out the back of the machine. This will even out the straw and chaff layer
across the entire field (Figure 7).
Figure 7: Straw and chaff being distributed out the back of the Harrow (7.5m shown)
The Claydon Straw Harrow can be used on stubble fields where the straw has been baled, or
on OSR/Bean stubble as a method to start weeds chitting and a form of slug control. In this
scenario the tines can be set to a very aggressive angle to maximise soil movement.
You should pull the Claydon Straw Harrow as quickly as you can (within reason). From time to
time (very rarely) the Straw Harrow can catch a lump or a tramline and start to bounce, in
this scenario you should slow down or stop until the machine has settled and then carry on as
normal. To avoid this altogether, it is recommended that a small amount of the Straw Harrows
weight (about 10-20%) should be carried on the tractors 3-point linkage.
When in use the Straw Harrow should be kept on the ground at all times and not lifted up
when making headland turns. On completion of the field, ensure the harrows tines are fully
folded back before the machine is folded up.
TIP:
Rape straw should be harrowed in the morning whilst the morning dew is present and
Wheat straw should be harrowed in heat of the sun. This will ensure the correct
shattering effect is achieved.
When harrowing a field it is recommended that the operator should turn inside the
headland tramline, this will avoid pulling grass or weeds into the field.

6.0. Care and Maintenance
The Claydon Straw Harrow requires very little maintenance in order to provide reliable
service. Prior to using the machine, the Straw Harrow should be checked for any broken tines
or hydraulic fluid leaks. Ensure all bolts are retightened after the first eight hours of use.
6.1. Lubricating Points
Lubrication should be performed using multi-purpose grease on a daily basis. An overview of
the 3m Straw Harrow can be seen in Figure 8 with the identification numbers corresponding
to the details of the lubrication points in Figure 9.
N.B. Lubrication should also be placed on the Harrows top link pin to prevent excessive wear
from the upper link ball at regular intervals.
