MAINTENANCE AND STORAGE  
1. Check that all nuts, bolts and screws are tight to be sure the  
equipment is in a safe working condition.  
2. Allow the engine to cool before storing in any enclosure.  
3.Toreducetheriskoffirekeeptheengine, silencerandbattery

inflated to the correct pressure (refer to the specifications on  
the back page of this manual). This is particularly important if  
the machine is to be taken on the public highway.  
7. Check the mower is in good working order, paying particular  
attention to brakes and steering.  
8. Check that all linkages, connections, and pivot nuts are secure  
and that the wheel nuts are torqued correctly.  
5. Replace worn or damaged parts for safety.  
OPERATION  
1. Do not operate the engine in a confined space where  
dangerous fumes can collect.  
2. Mow only in daylight or in good artificial light.  
3. Before starting the engine, disengage blade and attachment  
drives and ensure your feet are off all pedals.  
4.Takecareonslopesofmorethan10ºinclineordecline  
(maximum safe operation is at 15º).  
6. If the fuel tank has to be drained, this should be done outdoors.  
7. Be careful during adjustment of the machine to prevent  
entrapment of fingers between moving blades and fixed  
parts of the machine.  
8. Do not use steam cleaners or high-pressure washers directly  
towards the bearings or electrical components (Countax do not  
recommend the use of these power cleaners). Incorrect use  
could void warranty.  
5. Remember that there is no such thing as a ‘safeslope. Travel  
on grass slopes requires particular care to guard against  
overturning:  
SUPPLEMENTARY INSTRUCTIONS FOR THE  
USE OF COUNTAX D18/50 TRACTOR  
• Do not stop or start suddenly when going up or downhill.  
• Machine speed should be kept low on slopes and in tight turns.  
• Stay alert for humps and hollows and other hidden hazards.  
• Avoid mowing across the face of the slope.  
6. Watch for traffic when crossing or near roadways.  
7. Stop the blades rotating before crossing surfaces other  
than grass.  
8. When using the machine, never direct discharge of material  
towards bystanders or allow anyone near the machine while  
in operation.  
1. Use good sense at all times and to ensure this tractor is safe  
and serviceable, fit only original manufacturers  
supplied spares.  
2. When inspecting the area to be cut, note also the position of  
any stumps, manhole covers, bumps and depressions and  
avoid them to prevent damaging the blades.  
3. We recommend the use of standard diesel and that you ensure  
the fuel tank is full before you start the machine.  
4. Always disconnect both battery terminals before attempting  
any work in the engine compartment.  
9. Never operate the mower with defective guards, shields or  
without safety protective devices in place and in good  
working order.  
5. Do not leave the tractor unattended and running.  
6. DonotputhandsnearmovingbeltsorthePowerTake-Off  
pulley while it is rotating.  
10. Do not change governor settings to increase the revs of the  
engine. Operating the engine at excessive speed increases the  
hazard of injury.  
SAFETY SWITCHES  
11. Before leaving the operators position:  
• Disengage the drive to the cutter blades and attachments and  
lower the attachments.  
• Remove your foot from drive pedals and set the handbrake.  
• Stop the engine and remove the key.  
12. Disengage drive attachments, stop the engine and remove  
ignition key before:  
• Clearing blockages.  
SEAT SAFETY SWITCH  
Your Countax tractor is fitted with a switch that will turn OFF the  
engine and the cutter deck should you dismount.  
This is a safety back-up and should not be used voluntarily. If  
you want to dismount from the tractor and want the engine to  
continue running, first switch OFF the cutter deck, then apply  
the parking brake. You can now dismount. DO NOT LEAVE  
THE ENGINE IDLING FOR ANY LENGTH OF TIME. Should  
you try and dismount with the parking brake ON, the cutter deck  
will cut out after a short delay of a couple of seconds. Do not  
rely on this back up cutout. Ensure safety by switching the  
cutter deck off.  
• Checking, cleaning or working on the mower.  
• Refuelling.  
• Removing the grass catcher.  
• After striking a foreign object (inspect the mower for damage  
and make repairs before restarting the tractor).  
• If the machine starts to vibrate abnormally check immediately  
and call dealer if necessary.  
13. Disengage drive to attachments when transporting or  
not in use.  
PARK BRAKE SAFETY SWITCH  
Your Countax tractor is fitted with a safety switch activated by  
the Park Brake lever. This switch earths the ignition unless the  
brake is on. The engine will only start while the brake is  
engaged. Two red lights on the dash (Ignition, and Brake)  
indicate that the engine is ready to start.  
N.B Both safety switches work on the fuel cut-out solenoid.  
Should safety switches be activated, to re-start the tractor -  
the ignition switch should be turned compleately off.  
14. Reduce the throttle setting during engine run-out.  
15. Never work on the mower when the engine is running.

WARNING LIGHTS (fig 2)  
The ‘Key Startcontrols both the ignition and the starter. Insert  
the key and turn to the first position, the dash lights will come on  
(check that all is ready to start). For starting from cold, turn the  
key to the second ‘heatposition and hold for 10 seconds. Turn  
the key further to the third position to crank the engine, release  
the key as soon as the engine is running and it will return back to  
the first position. If the tractor is to be started from a hot engine,  
pre-heating is not required.  
1). Situated above the PGC net emptying switch are three  
warning lights. The first (red) light is a charge light. This light  
will illuminate when the key is turned to the first position, when  
the engine is started the light will go out. If the light comes on  
red  
whilst the engine is running consult your dealer.  
2). The second (yellow) light is a ‘high water temperature’  
warning light. This light will only come on if the water  
temperature becomes too high. Should this occur, stop the engine  
straight away and allow to cool. When the engine has cooled,  
CUTTER ON/OFF SWITCH  
check the water level in the radiator (see page 20) and top up  
yellow  
coolant as required. If the light stays illuminated – call your  
dealer immediately.  
The cutter switch controls the Electromagnetic Blade Clutch. It  
works like a light switch (but in reverse) – UP for ON and  
DOWN for OFF. Although it always returns to the central  
position and the cutter deck will automatically be turned off  
when the engine is switched off, it is not good practice to rely on  
this. The cutter deck should always be switched OFF as soon as  
you have finished cutting and certainly BEFORE stopping the  
engine or getting off the tractor.  
3). The third (green) light is an ‘oil pressurewarning light. This  
light will come on when the key switch is turned to the first  
position, and then go out when the engine is running. If the light  
illuminates whilst the tractor is in use – stop the engine  
green  
immediately and contact your dealer before attempting to restart  
your machine.

Cutting Decks  
MULCH MOWING  
Mulch Deck  
Pulley  
fig 1  
Mulching can save time, avoids gathering piles of rotting  
cuttings and feeds your lawn. It is however necessary to observe  
certain rules to mulch mow successfully:  
Arrangement  
• Reduce the height in each pass. If the grass has grown long  
make several passes to achieve the cut height you require.  
• Always cut with the throttle set to FAST– mulching needs the  
full running speed of the engine.  
• Mow often, particularly in spring and early summer. Short  
clippings of 25mm (1") or less decompose more quickly.  
• If possible avoid cutting in the wet.  
• If an unsightly residue of cuttings is being left – increase the  
cutting height.  
Vary the mowing pattern from cut to cut.  
• Always keep the underside of the cutting deck clean to ensure  
good grass flow.  
• Always check that the blades are sharp and in good condition  
– but do not attempt to sharpen or replace them yourself. New  
Countax blades are not expensive and it is good practice to ask  
your dealer to change them regularly.

REAR DISCHARGE DECK  
The Countax IBS Rear Discharge deck in contrast to the Mulch  
Deck, finely cuts the grass and then ejects it rearwards where it is  
collected by the Powered Grass Collector. This system offers the  
benefit of the ‘striped lawnfinish to your garden and tidies loose

• Are you on the tractor? – Unless you sit on the seat the safety  
switch cuts out the cutter deck.  
• Is the battery low? - The clutch engage switch will only  
operate if the battery is well charged.  
• Does the 10Amp barrel fuse on the printed circuit board need  
replacing?  
• That either the cutter switch or the safety switch on the seat is  
not faulty – if so, call your dealer.

Deck Levels - Front to Back  
The cutter deck should be set so that it is parallel to the surface it  
is cutting with a maximum variation from side to side, or front to  
back of 3mm. Check this by placing the tractor on a hard level  
surface and measuring the clearance heights front to back and  
side to side with a steel ruler or tape with the cutter set one  
adjustment from its lowest position (see page 6).  
fig 1  
If the cutter deck seems to require levelling first check these  
other possible causes:  
1. Are the tyres inflated to the correct pressure all round – if not,  
inflate to the correct pressures as specified on the back page.  
2.Arethecutterdeckhangerbrackets(fig2)movingfreely.To  
check this lift the cutter deck to its highest position and lift and  
rock it, watching to ensure that the brackets move freely – if  
not clean and grease.

3. Now locate the front to back adjustment rod to the right offside  
of the cutter. At the rear end of this rod you will find the  
Trunnion (fig 2) that links the rod to the deck hanger bracket.  
Both the Trunnion and the rod are threaded and adjustment is  
achieved by rotating the Trunnion to shorten or lengthen  
the rod.

Cutter - Levelling Side to Side  
LEVELLING SIDE TO SIDE  
fig 1  
Adjustment is best done with the deck in a position one up from  
its lowest cut – check the level both sides and levelling is then  
achieved by adjusting the left (nearside) of the deck at two  
points:  
REAR ADJUSTMENT  
1. Find the deck level disk (fig 1) near the back nearside wheel.  
underneath the actuator lifting arm. This disk has a concentric  
slot in which the deck-levelling rod is located.  
Deck Level Disk  
located underneath actuator  
2. Using a 1/2" spanner, loosen the 5/16" Nyloc nut A securing  
this stud just enough to permit some movement.  
3. Now lift or lower the deck depending on the adjustment you  
wish to achieve. This will move the stud up or down the disk B  
– the higher up and nearer the centre of the disk the higher  
the deck.  
fig 2  
4. Check with your ruler or tape and having levelled the deck at  
the rear, re-tighten the Nyloc nut.  
A
FRONT ADJUSTMENT  
1. Having levelled the rear of the deck, check if the front is level.  
If not, you will need to find the deck adjustment plate (fig 3)  
which is forward of the cutter deck near the front  
(nearside) wheel.  
2. Before making adjustments loosen the two sets of nuts and  
bolts (A and B) securing the deck levelling bracket (C) using a  
13mm spanner and 13mm socket.  
3. Then using a 13mm spanner, loosen (upper) locknut (D).  
4. Now adjust the height by using a ratchet or spanner to turn the  
Nyloc nut (E) clockwise (up) to raise the deck or anti-  
clockwise (down) to lower it.

Please note:  
Unless caused by our negligence, Countax  
cannot accept any liability for any damage to  
persons or property attributable to failure to  
comply with the instructions in this manual. To  
be absolutely sure that your warranty terms are  
not breached, service work should only be  
carried out by a Countax dealer.  
5. When level is achieved tighten up all nuts and bolts except E.  
For the closest cut, set the anti-scalp wheels in the middle  
adjustment holes. If you are experiencing scalping this can be  
minimised by setting the wheels in the lowest adjustment holes.

1. Is the engine to cutter drive belt slipping? Check that the drive  
belt tension lever (fig 1) under the left running board is in the  
rear (tensioned) position. If not, rectify – this is the most likely  
cause.  
2. Has debris collected in the cutter deck pulley housing

The correct tension of the cutter drive belt (engine to deck) is  
critical. If incorrectly set it can lead to engine damage.  
fig 2  
To check the tension, follow this procedure:  
1. Put the deck in a middle cutting height (position 5 on the HE  
illuminated indicator).  
2. Select a midway position on the belt between the front

REMOVE THE NET  
ToconnectthePoweredGrassCollector(PGC)totheD18/50  
tractor, ensure both are on an even surface with the locking  
levers (fig 3) on the collector facing the lift arms of the tractor.  
Move the collector manually to the tractor. Lower the lift arms  
using the auxiliary lift switch button (page 4) on the dash  
console.  
When removing the net, we suggest you employ the assistance of  
another person.  
1. Partially open the Sweeper net (100mm(4")). Disconnect  
opening rod by pulling back on sprung locking tube and  
uncoupling from pin (fig 2).  
2. Repeat either side.  
3. Undo net locking clip (both sides), unhook levers from  
locating pins (see fig 2).  
4. With either person standing each side of the collector net, slide  
the net off the locating arms.  
At the end of each lift arm you will find a locating lug. Slide the  
channels on either side of the PGC over the lugs but do not  
engage the locating lever yet. Ensure that the rubber flap at the  
opening of the PGC located on top of the transmission grass  
deflector.  
5. Reverse operation for fitting.  
fig 1  
INSTALLING THE DRIVE BELT  
Place the drive belt over the PTO pulley (beneath the tractor  
seat). Standing adjacent to the tractor, extend the belt with both  
hands parallel to the ground. Now twist the belt to form a figure  
‘8the right hand up and the left hand down. In this position  
place the other end of the belt over the Powered Collector pulley.  
Be sure that this is installed the right way round otherwise the  
brush will work in reverse and collection will be poor! Lock  
locating lever (fig 3) over the lift arm lugs. Rotate the locking  
clips over lift arm lugs. Connect net empty plug to socket as  
showninfig1.Todisconnect, reversethisprocedure.

Engaging the locating lever tensions the belt which should not be  
run too tight – to check the tension there should be a 19mm  
deflection with light finger pressure (2Kgs) at a midway point  
between PTO pulley and sweeper pulley. It is important after  
attaching the sweeper to the tractor to check the belt tension and  
adjust this if necessary this must be done before the sweeper is  
put into operation and with the sweeper on the ground. With light  
finger pressure, 2Kgs (4lbs) there should be a total deflection of  
19mm (3/4") at midway point between PTO pulley and the  
sweeper pulley. If a spring balance is available a pressure of 4-  
5lbs (1.81-2.26Kgs) is required for a deflection of 3/4" (19mm).  
If the belt tension is incorrect, it can be adjusted by movement of  
sweeper locking levers on the threaded rod. Ensure the lock nuts  
are suitably tightened after adjustment. N.B. Do not over-tighten  
lock nuts as lever needs to pivot.

You can check the contents of the grass box through the clear  
cover. When it is full raise the collector to the transport position.  
Drive to your tipping area; reverse to the pile, select neutral then  
depress the PGC net empty switch (see page 4 fig 1).  
CHECK LIST  
Not picking up satisfactorily – check:  
1. That the PTO lever is engaged.  
2. That PTO pulley beneath the seat is turning – if not call  
your dealer.  
3. That the Collector Belt is not reversed (if it is correct the brush  
will revolve against the forward direction of the tractor -  
see below).

4. That the brush height adjustment is not too high or too low –  
start at the highest setting and lower until it begins to collect.  
5. That there is not a build up of congealed grass on the leading  
edge on the brush guard.  
6. That the brush is not clogged.  
7. That the collector brush is not slipping – if so:  
• Adjust tension (see page 15)  
• Or replace worn or damaged belt (see page 15)

to prevent marking your turf. They are of thicker section and  
tougher than most 4 ply tyres.  
Persistent punctures and tyre deflation are nevertheless a  
problem experienced by about 5% of Countax customers. This is  
not a problem just for Countax owners - it is shared by the users  
of all types of off-road machinery fitted with pneumatic tyres. In  
practically every case there is one common cause – THORNS!  
Blackthorn, Hawthorn, and Rose are usually at the bottom of it  
and will puncture any tyre not fitted with very expensive guards.  
There are less expensive ways to overcome this problem.  
Front  
fig 1  
Jacking Point  
Check and avoid these possible causes:  
1. The rim of the wheel has become damaged – breaking the seal  
on the tubeless tyre. There are two possible solutions:  
• If the damage is not severe, treat with Countax tyre sealant  
(Pt No. 52903501)  
• If the damage is significant – order a new wheel  
Front wheel – (Pt No.198000500)  
Rear wheel – (Pt No. 198000700)

fig 2  
Point  
2. You have Hawthorn, Blackthorn or Wild Rose in your hedges  
– these will puncture any tyre. It makes sense to check the area  
you intend to cut or drive over and to remove any branches.  
The long-term solution is to treat all four tyres with Countax  
tyre sealant – follow the instructions on the bottle.  
If your tyres spin or lose grip check:  
1. Are the tyres inflated to the correct pressures, check  
back page?  
2. Are you driving too fast for the conditions? If so, select a  
slower speed.  
REMOVAL OF FRONT WHEEL  
1. Apply the parking brake.  
2. Place chocks under all wheels that are to remain on the  
ground.

The coolant level should be checked daily as a matter of routine.  
ONLY EVER INSPECTCOOLANTWHEN THE ENGINE IS  
COMPLETELY COLD. To check level, follow this procedure:  
• Check the coolant level in the sub-tank. If the level is close to  
the lower limit, remove the sub-tank cap and fill with coolant  
to the upper limit.  
• Remove the radiator cap and check the amount of coolant in  
the radiator. Fill with coolant to the overflow if the level  
is low.  
Check the difference of the cooling water level before and after  
operation once a week. Before operation when the engine is cold  
there should be a low level of coolant. Immediately after  
operation (when the engine is hot) there should be a high level of  
coolant. If there is no difference in coolant level before and after  
the engine operation open the radiator cap and check the coolant  
volume. Also check the hose linking the radiator and the sub tank  
to make sure that it is not disconnected, loosened or torn. Check  
that the hose is inserted to the lower level of the sub-tank (when  
engine is cold).
