  tractor is not equipped with a rollbar and seat
  beit, see your Ford Tractor Equipment Dealer.
• Always use the seat belt when the rollbar is
  installed. Do not use the seat belt if the
  rollbar is removed from the tractor.
• Use the handholds and step plates when getting on
  and off the tractor to prevent falls. Keep steps
  and platform cleared of mud and debris.
• Do not permit anyone but the operator to ride on
  the tractor. There is no safe place for extra
  riders.
• Keep decals clean, replace all missing, illegible
  or damaged safety decals.
• SERVICING THE TRACTOR
• Cooling system operates under pressure which is
  con- trolled by the radiator cap. It is
  dangerous to remove the cap while system is hot.
  Always turn cap slowly to the first stop and
  allow the pressure to escape before removing the
  cap entirely.
• Do not smoke while refueling the tractor. Keep
  any type of open flame away. Wait for engine to
  cool before refueling.

   lin drawbar in the down position. Use only a
   drawbar pin that locks in place. Pulling from
   the tractor rear axle a any point above the axle
   may cause the tractor to upset
4. It the front end of the tractor tends to rise
   when heav implements are attached to the
   three-point hitch, insta front end or front
   wheel weights. Do not operate th tractor with a
   light front end.
5. Always set the hydraulic selector lever in
   position cor trol when attaching equipment,
   when transportin. equipment. Be sure hydraulic
   couplers are properl mounted and will disconnect
   safely in case of accider tal detachment of
   implement.
6. Do not leave equipment in the raised position.
7. Use the Flasher/Turn Signal Lights and SMV signs
   whe traveling on public roads both day and night
   unless pre hibited by law.
8. Dim tractor lights when meeting a vehicle at
   night. B sure the lights are adjusted to prevent
   blinding an or coming vehicle operator.

• DRIVING THE TRACTOR
• Watch where you are going especially at row ends,
  o roads, around trees and any low hanging
  obstacle.
• To avoid upsets drive the tractor with care and
  at speed compatible with safety, especially when
  operating rough ground, crossing ditches, slopes,
  and whet
• ing.
• Lock tractor brake pedals when transporting on
  roads t provide two wheel braking.
• Keep the tractor in the same gear when going
  downhi as used when going uphill. Do not coast
  or free whe down hills.
• Any towed vehicle whose total weight exceeds
  that the towing tractor must be equipped with
  brakes fc safe operation.
• When the tractor is stuck or tires frozen to the
  groun back out to prevent upset.
• Always check overhead clearance, especially whe
  transporting the tractor.

• OPERATING THE P.T.O.
• When operating P.T.O. driven equipment, shut off
  tL engine and wait until the P.T.O. stops before
  getting o the tractor and disconnecting the
  equipment.
• Do not wear loose clothing when operating the
  pows take-off, or when near rotating equipment.
• When operating stationary P.T.O. driven equipmen
  always apply the tractor parking brake and block
  tt rear wheels front and back.
• Do not add dressing, install or remove the belt
  while tf belt puliey is in motion.
• To avoid injury, do not clean, adjust, unclog or

CONTROLS AND INSTRUMENTS
Structure (ROPS) or safety cab and seat belts,
ROPS and safety cabs are effective in reducinc
injuries during tractor overturn accidents. Over
turning a tractor without a ROPS or safety caL
can result in serious injury or death.
SEAT, LIGHT, AND ENGINE CONTROLS TRACTOR SEAT
Your new Ford Tractor is equipped with a deluxe
seat or a super comfort seat, Figure 1.
Adjust the seat to your weight by turning the
knob (1). Raise or lower the seat by loosening
the height adjustment nuts (3). Slide the seat
ahead or back by depressing the seat track latch
(4). If more fore-aft adjustment is required than
that provided in the seat track, the two seat
assembly mounting bolts may be loosened and the
seat slid ahead or back in the seat frame
mounting slots (5).
Roll Over Protective Structure (ROPS), safety
cabs and seat belts are available for your Ford
tractor. If your tractor is not equipped with a
ROPS or safety cab and seat belts see your Ford
Tractor Equipment Dealer.
All tractors equipped with a ROPS or cab are also
equipped with a seat belt which, when used by the
operator, maximizes the protection of- fered by
the ROPS. ALWAYS use your seat belt when the ROPS
is installedseat belts save lives when they are
used. Do not use your seat belt when the ROPS is
not installed on the tr tor.

CAUTION Never attach chains, ropes, or cables
to the ROPS or Cab for pulling purposes, this is
very dangerous, as the tractor Wf// tip backward.
Always pull from the trac- tor drawbar.
If the seat belt must be cleaned, use soap and
water. Do not use carbon tetrachloride, naptha,
etc., as cleaning agents because these
chemicals will weaken the belt webbing. Also, for
the same reason, do not bleach or dye the webbing.
The seat belt should be examined every 6-12
months and should be replaced if it is frayed,
worn, or shows signs of deterioration.

DRAWBAR
POSSIBLE DAMAGE TO THE ROPS
If the machine has rolled over or the ROPS has
been in some other type of accident (such as hit-
ting an overhead object during transport) you
must replace the ROPS to get the original protec-
tion.
CAUTION II the ROPS cab is remov- ed or
replaced, make certain that the proper hardware
is used and the recommended torque values are ap-
plied to the attaching bolts.
After an accident, check for damage to the
ROPS, the operators seat, the seat belt and the
seat belt mountings. Before you operate the
machine, replace all damaged parts.
Be careful when driving through door openings
or under low overhead objects. Make sure there
is sufficient clearance for the roll bar or cab
to clear the structure or oblect.
DO NOT TRY TO WELD THE ROPS OR TO MAKE THE ROPS

PROOFMETER
If the light illuminates while the engine is
runn- ing, stop the engine and service the air
cleaner as described in AIR CLEANER page .
The Proof-Meter (3), Figure 3, indicates engine
revolutions per minute (rpm) and hours and
tenths of hours your Ford Tractor has operated,
based upon an engine speed of 1666 rpm. Use the
Proof-Meter in conjunction with the
transmission shift decal and the ground speed
chart on page to determine ground speed.
Operation of the engine at speeds above or below
1666 rpm will cause the Proof-Meter to ac-
cumulate hours faster or slower than clock
hours. Use the Proof-Meter as a guide to deter-
mine hourly service and maintenance intervals.
CHARGE INDICATOR WARNING LIGHT
The charge indicator warning light is shown at
(8), Figure 3. When the light is on, it is an
indica- tion that the battery is not being
charged. In- vestigate and correct the cause, or
the battery will become fully discharged.
FUEL GAUGE
TEMPERATURE GAUGE
The fuel gauge needle (2), Figure 3, indicates
the fuel level in the tractor. If equipped with
an aux- iliary (saddle) fuel tank, Figure 7, the
gauge in- dicates the fuel level in relation to
the total capacity of both tanks. The auxiliary
(saddle) fuel tank, Figure 7, is connected to the
upper tank and is filled when the upper tank is
filled. There is no separate filler for the
auxiliary tank.
The engine coolant temperature gauge is shown at
(4), Figure 3. When the needle is in the black
zone, the engine coolant is at its normal
operating temperature. When the needle is in the
blue zone, the engine is cold. The engine is hot
when the needle is in the red zone.
ENGINE OIL PRESSURE WARNING LIGHT The engine oil
pressure warning light is at (10), Figure 3. If
the light is ON while the engine is running,
stop the engine iromediately and in- vestigate
the cause. It is important to remember that this
light indicates pressure only. The operator
must still check the crankcase for pro- per
engine oil level.
AIR CLEANER RESTRICTION WARNING LIGHT
The air cleaner restriction warning light
(9), Figure 3, illuminates when the air cleaner
re- quires service and the engine is running.
When the key-starter switch is turned to the ON
posi- tion the light will illuminate to allow
you to check that the light is functioning
properly and will extinguish when the engine
starts.

HYDRAULIC LIFT CONTROLS
CONTROL LEVER
The hydraulic control lever (1), Figure 14, con-
trols the hydraulic lift arms. Pull the lever
rear- ward to raise the arms. Push the lever
forward to lower the arms. The quadrant will have
one or two quadrant stops to facilitate returning
the control lever to the same point.
CAUTION Always engage the park- ing brake before
leaving a tractor equipped with Dual Power. A
tractor with Dual Power will roll freely even
though the transmission is in gear.
FRONT WHEEL DRIVE (where fitted)
SELECTOR LEVER
Front wheel drive transmission greatly improves
traction in difficult conditions. The drive to
the front wheels is designed to be engaged or
disengaged with the tractor stationary or mov-
ing.
The selector lever (3), Figure 14, determines the
hydraulic system response to changing draft
loads.
The standard hydraulic system on the Ford 5610
and 6610 has a seven position selector lever
which provides position control in the rearward
position and draft control in the forward
position with varing degrees of response in
the in- termediate selection points.
To engage the drive to the front wheels push the
switch (5), Figure 12, forward. Pull the switch
rearwards to revert to rear wheel drive only.
Tractors with Front Wheel Drive, engaged or
disengaged, should not be allowed to exceed 25
mph (40 kph). Over speeding by towing or
coasting downhill with clutch depressed or
transmission in neutral may cause failure of the
drive shaft.
The standard hydraulic system on the 7610 uses
the load monitor draft sensing system. The
selector lever is used to select three ranges of
load monitor response, position control or three
ranges of upper link draft control. The most for-
ward position provides maximum response in upper
link draft control with decreasing response
in the second and third positions. The forth
(center position) is position control while
fifth, sixth and seventh (full rearward)
positions provide increasing response in load
monitor draft control.
CLUTCH
The foot operated clutch, Figure 12, must be
completely depressed to stop forward travel.
Always depress the clutch pedal fully when
changing gears to prolong component life.
