3.1 HOW TO OPERATE SAFELY _____________________________________________
WARNING
EQUIPMENT THAT IS NOT OPERA TED CORRECTL Y OR BY PERSONNEL WITHOUT TRAINING CAN
BE DANGEROUS.
Know the location and c orrect use of all controls. Befor e any use of the machi ne, personnel w ithout training
must receive instruction from personnel with experience in the machines operation.
3.1.1 Safe operation

CAUTION
To Help Prevent Injury, Always Wear
Safety Glasses, Leather Wo rk Shoes Or
Boots, A Hard Hat And Ear Protection.
1. Do not operate with loose, damaged or missing components. Whenever possible mow when grass is
dry
2. First mow in a test area to become thoroughly familiar with the operation of the controls.
3. Study the area to determine the best and safest operating procedure. Consider the height of the grass,
type of terrain, and condition of the surface. Each condition will require certain adjustments or
precautions.
4. Never direct discharge of material toward bystanders, nor allow anyone near the machine while in
operation. The owner/operator is responsible for injuries inflicted to bystanders and/or damage to their
property.
5. Use discretion when mowing near gravel areas (roadway, parking areas, cart paths, etc.). Stones
discharged from the implement may cause serious injuries to bystanders and/or damage the
equipment.
CAUTION
Remove All Debris From The Site Before
Mowing. Enter A New Area Cautiously
Always Operate At Speeds That Allow

7.3 ATTACHING THE MOWER TO THE TRACTOR P.T.O. SHAFT __________________
A standard P.T.O. shaft is provided and this will have to be
shortened in length to suit the tractor being used. It is
essential that no more than is necessary is cut off as
maximum engagement of the sliding portion is needed to
prevent excessive wear.
Adequate removal of sharp edges and chamfering of the
cut ends must be carried out.
NOTE
On certain tractors it will be impossible to lift the machine to the maximum height on the three point linkage
without the sliding part of the P .T.O. shaft disengaging. Stops must be set correctly on the tractor lift quadrant to
limit the lift height to prevent the disengagement of the P.T.O. shaft.
2. Stop the tractor engine.
3. Connect the tractor lower lift arms to the 2-hitch
points (A) on the main crossbeam, using the
lower hole in the hitch plates to fit the
connecting pins and spring clips.
Connect the tractor top link (B) to the machine.
IMPORTANT
Select the pair of holes in the 'A' frame which
allows the top link to take up as near a horizontal
position as possible.
2. Fit pin (B) and secure with pin and spring ring.
3. Extend the top link and remove the stabiliser pin
from the rear of the unit pivot support plates.
Stow this pin in the holes in the lugs at the front
of the main crossbeam and secure with spring
pins.
4. Shorten the top link until the 'A' frame becomes vertical. Attach the jubilee clip (supplied) to the top link
up against the end of the turn buckle and tighten securely in this position.
5. Connect up P.T.O. shaft (C) to the machine and tractor.Connect lift hose QRC to Tractor QRC.
en-19
7 OPERATION
1. Start the tractor engine and lift the machine fully by means of the tractor lifting quadrant lever.
2. Switch off the engine.
3. Adjust the tractor RH lift rod length to level the main crossbeam of the machine.
4. Measure the height of the crossbeam from the ground at each end to ensure the machine is level.
5. Adjust the length of the check chains so that there is a minimum of slack when the tractor arms are
fully raised. This will prevent excessive side swing of the machine when transporting.
NOTE
If external tractor check chains are fitted, they should be adjusted so that no part of the lift arms can foul
against the hydraulic pump or any of the fittings when the machine is in the cutting position. This will prevent
excessive side swing of the machine when transporting.
Before this adjustment can be made, the height of cut of all three units must be set accurately with the machine
on a level, hard surface (see page 23). The ‘A’ frame must be vertical.
On the area to be cut, make an initial cut of approximately 20 metres. Examine the finish of cut across the width
of the swathe - it is likely that the 2-front units will be cutting lower than the rear unit. If necessary, to obtain an
even cut, extend the top link by 1½ to 2 turns.
IMPORT ANT
Do not lengthen the top link by more than 3 turns; the need for adjustment in excess of this indicates that the
height of cut settings on the units were not equal initially.
Any subsequent changes in height of cut will not effect the length of the top link; but it is important that is the units
are set up by using spacers between the ground and bottom blade, the top link should be shortened to its original
length, ie. until the turnbuckle contacts the jubilee clip. After resetting the height of cut by this method, the top link
should again be lengthened by the same amount.
NOTE
Alternatively, the height of cut setting on the individual units can of course be adjusted slightly to obtain an even
finish without altering the length of the top link.

7.4 REMOVING THE MACHINE FROM THE TRACTOR __________________________
To remove the machine from the tractor, reverse the attachment instructions.
1. The stabiliser pin (A) must be in place over the
rear unit trailing arm (B) before the machine is
removed from the tractor 3-point linka ge; this
ensures that the machine is stable when
removed from the tractor.
2 The stabiliser pin MUST always be removed
from over the rear unit trailing arm (A) for all
mowing and transporting operations. When not
used store the pin in location (B) to prevent loss.
REMEMBER: It is not necessary at anytime when assembling or removing the mower from the tractor to
dismantle, or disturb, any hydraulic pipe joints or components. should servicing be necessary during use, it must
be carried out by a trained service person.
NOTE
This instruction applies to the centre and wing units

7.5 MOWING_____________________________________________________________
1. Start the tractor and lower the lift arms.
2. E ng age the tra ct or P.T.O.
3. Select tractor gear ready to move off.
4. Move the mower control levers forwards to engage the forward drive to the cutting units.
CAUTION
Always put the drive controls in the neutral position and switch off the engine before dismounting from
the tractor.
CAUTION
IMPORTANT
Do not reverse the tractor with the machine lowered. Always lift the machine on the tractor 3 - point linkage
before moving in reverse, and when obstructions are met during cutting.
7.6 TRANSPORTING______________________________________________________
1. Move the cutting cylinder control levers to neutral.
2. Raise the machine fully by operating the tractor lift lever.
3. Put the tractor P.T.O drive in neutral to avoid unnecessary circulation of oil in the hydraulic
system.
It is imperative that the P.T.O. drive is disengaged and the valve control lever is in neutral before the machine is
lifted.
No automatic cut out of the hydraulic drive is provided and damage will occur to the machine components if the
P.T.O. is not disengaged.
IMPORT ANT
The tractor P.T.O. drive MUST NOT be re-engaged until the machine is returned to the cutting position.

OPERATION 7
7.7 CUTTING PERFORMANCE ______________________________________________
NOTE
Due to the low power requirement of the Hydraulic 5 it is quite acceptable to use the tractor with the engine
speed reduced to as low as 900 rpm. This may be necessary when sparse grass of uneven height is being cut.
It is also convenient for maneuvering, noise and improves operator comfort, and reduces tractor engine wear.
Slow cutting cylinder speeds reduce cylinder and bottom blade wear.
It is necessary to use increased engine speeds to achieve satisfactory cutting and grass discharge in wet, lush
grass conditions or where higher cuts/yard are required at reasonable forward speeds.
7.8 UNBLOCKING CUTTING UNITS
1. Switch off cutting unit drive, lift out of work and move machine to flat level ground.
2. Switch engine off and remove the ignition key.
3. Using a piece of wood and personal protective equipment e.g. eye protection and gloves, remove
blockage. The reel can be rotated by using a spanner on the hexagon drive on the reel non drive end.
4. Check blades for damage and replace or repair if necessary.
5. Start engine and run the cutting units to check for correct operation.
7.9 BACKLAPPING _______________________________________________________
• Backlapping is a process which will lightly grind the reel to the bedknife whilst mounted on the mower.
• If significant amounts of metal are to be removed then the cutting unit should be reground on a
specialised grinding machine.
• Before any Backlapping is carried out, Ransomes Jacobsen recommends that the Backlapping process
should be risk assessed as a workshop process by the manager of the machine.
• Backlapping should only be carried out by trained staff.
• Jacobsen recommend that grinding paste is only applied to the reel when it is stationery, the engine is
off and the parking brake applied.
• When applying grinding paste the reel should only be rotated by appropriately sized piece of wood and
not by hand.
• Place reels in the most accessible position for applying the paste.
• After applying the grinding paste the person Backlapping should return to the seat, engage the relevant
controls and run the reels in reverse.
en-23
7 OPERATION
• When the desired finish is achieved switch off the mower, clean off any surplus paste, reset the reel to
bedknife and return the controls to the normal mow positions.

PROCEDURE
1. Apply an even coat of Backlapping compound to the entire length of each blade of the reel.
2. Start the tractor and set the tractor P.T.O. to allow reels to rotate at a slow speed.
3. Slowly adjust the P.T.O. speed until the desired reel rotation speed is attained. It should be slow
enough so that the reel will not throw off the Backlapping compound as it spins.
4. Once all the blades on the reel are uniformly sharp, shut off the engine and move the PTO to the off
position.
7. Wash all of the Backlapping compound from all of the heads. Once they are thoroughly cleaned and
dry, apply a light film of oil to the cutting edges to help prevent rust.
8. After Backlapping, the reel to bedknife adjustment should be made again.

10 QUALITY OF CUT TROUBLESHOOTING ________________________________
It is recommended that a “test cut” be performed to
evaluate the mower’s performance before beginning
repairs.
An area should be available where “test cuts” can be
made. This area must provide known and consistent
turf conditions to allow accurate evaluation of the
mower’s performance.
Another “te st cut” sh ould be perfor med aft er the completion of the repairs and/or adjustments to verify the
mower’s performance.
Before performing a “test cut” to diagnose cut appearance and mower performance, the followi ng items
must be verified to ensure an accurate “test cut.”
1. Mowing (Ground) Speed.
2. Reel Bearing Cond ition and Pre-Load ( End Play)
Adjustment.
3. Reel and Bedknife Sharpness.
4. Bedknife Alignment to Reel.
5. Reel- to-Bedknife Contact.
6. Height-of-Cut (HOC).
7. Roller and Roller Bearing Condition.
10.1 WASHBOARDING ___________________________________________________
Washboarding is a cyclical pattern of varying cutting
heights, resulting in a wave-like cut appearance. In
most cases, the wave tip-to-tip distanc e is approximately
6—8 in. (15—20 cm). Colour variation (light-to-dark)
may also be noticed.
This conditi on is us ually caus ed by a roc king moti on
in the cutting unit(s). This condition is found mostly
on mowers with multiple (suspended) cutting units,
but other causes can produce the same result.
Washboarding may also be caused by variations in
the turf.
NOTE: Arrow indicates directi on of travel .
Probable Cause Remedy
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
Grass build-up on roller. Clean the roller and use scrapers or brushes.
Roller is out of round. Replace roller.
Mowing in the same direction. Change mowing direction regularly.
Use of a groomer on cleanup pass. Groomers must be used only in a straight line.

10 QUALITY OF CUT
TN0220
10.2 MARCELLING______________________________________________________
Marcelling, like wash boarding, is a cyclical pattern
of varying cutting heights, resulting in a wave-like cut
appearance. In most cases, the wave tip-to-tip distance is 2 in. (5 cm) or less.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
HOC (height-of-cut) setting is too low for turf condi-
tions.
Cutting reel diameter is worn. Check cutting reel diameter and replace if worn.
Check/adjust HOC to turf conditions.

10 QUALITY OF CUT
TN0221
10.3 STEP CUTTING _____________________________________________________
Step cutting occurs when grass is cut taller on one
side of a reel than the other or one cutting unit to another. This is usually caused by mechanical wear or
an incorrect roller or HOC (height-of-cut) adjustment.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
HOC (height-of-cut) settings are different from one
side of a reel to the other or from one cutting unit to
another.
Worn front roller bearings. Check/replace front roller bearings.
Reel-to-bedknife contact is different from one side of
the cutting unit to the other or from one cutting unit
to another.
Cutting reel movement is restricted. Check/remove cutting reel movement obstruction.
Variations in turf density. Change mowing direction.
Machine weight distribution is uneven. Check/adjust tire inflation pressure.
Check HOC adjustment of cutting units.
Check reel-to-bedknife contact.

10 QUALITY OF CUT
TN0222
10.4 SCALPING ________________________________________________________
Scalping is a condition in which areas of grass are
cut noticeably shorter than the surrounding areas,
resulting in a light green or even brown patch. This
is usually caused by an excessively low height-of-cut
(HOC) setting and/or uneven turf.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
HOC (height-of-cut) settings are lower than normal. Check/adjust the HOC settings.
Improper reel-to-bedknife adjustment. Adjust reel-to-bedknife setting for desired HOC.
Turf too uneven for the mower to follow. Change mowing direction.
Cutting too much grass at one time. Mow more often.
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.

10.5 STRAGGLERS ______________________________________________________
Stragglers are scattered blades of uncut or poorly
cut grass.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
Bedknife improperly adjusted. Adjust reel-to-bedknife setting.
Dull reel or bedknife cutting edges. Sharpen or replace reel blade and bedknife as nec-
essary.
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
Grass is too tall. Mow more often.
Mowing in the same direction. Change mowing direction regularly.

10 QUALITY OF CUT
TN0224
10.6 STREAKS _________________________________________________________
A streak is a line of uncut grass. This is usually
caused by a nicked or bent bedknife.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
Damaged bedknife. Replace bedknife.
Damaged or unevenly worn reel. Inspect reel. Replace as needed.
Loose or missing bedknife fasteners. Check bedknife screws. Tighten loose screws; re-
place missing screws.
Turning too aggressively. Cutting units don’t overlap
around turns or on side hills.
Tire mats down grass before it is cut. Check/adjust tire inflation pressure.
Wet grass is matted down before it is cut. Mow when grass is dry.
Turn less aggressively to allow cutting units to overlap. Change mowing direction or pattern on side
hills.

10.7 WINDROWING______________________________________________________
Windrowing is the deposit of clippings concentrated
at one end of cutting unit(s) or between two cutting
units, forming a line in the direction of travel.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
Grass is too tall. Mow more often.
Mowing while grass is wet. Mow when grass is dry.
Grass built up on roller(s). Clean roller(s) and scraper(s).
Grass collecting on bedknife. Adjust reel-to-bedknife setting.
en-37
10 QUALITY OF CUT
10.8 RIFLING OR TRAMLINING____________________________________________
Rifling or tramlining is a pattern of varying cutting
heights, resulting in a wave-like cut appearance,
usually due to heavy contact points across a reel
and/or bedknife.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
Reel and/or bedknife unevenly worn. Inspect bedknife and reel. Sharpen or replace reel
and bedknife as necessary.
Missing, loose, or over torqued bedknife screws. Install, replace or tighten bedknife screws to proper
torque setting.
Mowing (ground) speed is too fast. Reduce mowing (ground) speed.
12.9 MISMATCHED CUTTING UNITS _______________________________________
Mismatched cutting units is a pattern of varying cutting heights, resulting in a stepped cut appearance,
usually due to mismatched HOC (height-of-cut) adjustment from one cutting unit to another.
NOTE: Arrow indicates direction of travel.
Probable Cause Remedy
HOC inconsistent from one cutting unit to another. Check/adjust HOC on cutting units.
Difference in mower ride height side to side. Check/adjust tire inflation pressure.
