TECHNICAL INFORMATION
HARDWARE
GENERAL
The MC22, MC28, and MC35 tractors have been
built using metric hardware.
NOTE: Be sure to use the hardware specified when
using tapped holes, as trying to install a metric bolt in
an inch thread, or an inch bolt in a metric thread, will
damage the thread.
Certain hardware must be tightened to specific
torque specifications. If specific torque specifications
are not noted, tighten the hardware to the standard
torque chart specification listed in this manual.
PLATING
Hardware used on New Holland balers is plated with
zinc chromate (gold color). Gold colored hardware
has different torquing requirements from unplated or
zinc plated (silver color) hardware because of the
difference in the coefficient of friction of the plating
material. The torque charts in this manual list the
correct specifications for gold, silver, and unplated
bolts.
NUT TIGHTENING
Whenever possible, the nut should be tightened, not
the head of the bolt. When tightening using the bolt
head, the clamp load can be lost because some of
the torque applied twists the bolt instead of
tensioning (stretching) it. The tension on the bolt is
what holds the joint together.
Approximately 90% of the torque applied during
assembly goes to overcoming friction between the
parts. The other 10% is used to tension (stretch) the
bolt. After assembly, the frictional forces disappear,
which is the basis for the saying “If it does not fail
during assembly, it will not fail in service.” The bolt
may later fail due to other factors, but not from being
overtightened.
LOCKNUTS
Most locknuts are coated with a special lubricant that
is dry to the touch. Any time a locknut is used, a lower
than normal torque is required. Refer to the torque
charts in this manual for specific values.
JAM NUTS
When using a jam nut to lock a regular nut, the jam
nut should be installed first and tightened to one half
the recommended torque, then held in place while
installing a regular nut to the recommended torque.
THREAD LUBRICATION
The addition of antiseize compound, Molykote, oil,
graphite, or any other lubricant to a bolt decreases
the friction between it and a nut. This makes it
necessary to reduce the recommended torque to
prevent overtensioning of the bolt. When using the
torque charts in this manual, decrease the value by
20% whenever a lubricant is used.

SAFETY PRECAUTIONS
The following precautions are suggested to help prevent accidents.
SEE SPECIFIC INSTRUCTIONS IN TEXT FOR DETAIL.
A careful operator is the best operator. Most
accidents can be avoided by observing certain
precautions. Read and take the following
precautions, before operating the commercial
mower, to prevent accidents. Equipment should be
operated only by those who are responsible and
instructed to do so.
This cutting machine is capable of amputating hands
and feet and throwing objects. Failure to observe the
following safety instructions could result in serious
injury or death.
COMMERCIAL MOWER
1. All persons who will operate the unit should read
the Operators Manual carefully before using the
equipment. Lack of operating knowledge can
lead to accidents.
2. Permit only properly trained and qualified per-
sons to operate the unit.
3. Use the step plates when getting on and off the
unit to prevent falls. Keep steps and platform
cleared of mud and debris.
4. Use an approved Rollover Protective Structure
(ROPS) and seat belt for safe operation. Over-
turning a unit without a ROPS and seat belt can
result in death or injury. If the standard ROPS or
seat belt has been removed, see your New Hol-
land Dealer for a replacement.
5. Always use the seat belt with ROPS. If the ROPS
has been removed, do not use the seat belt.
6. Do not permit anyone but the operator to ride on
the unit. There is no safe place for extra riders.
7. Replace missing, illegible, or damaged safety
decals.
8. Keep safety decals clean of dirt and grime.
Servicing the Commercial Mower
1. The cooling system operates under pressure
which is controlled by the radiator cap. It is dan-
gerous to remove the cap while the system is hot.
Always turn the cap slowly to the first stop and al-
low the pressure to escape before removing the
cap entirely.
2. Do not smoke while refueling the unit. Keep any
type of open flame away. Wait for the engine to
cool before refueling.
3. Keep the Commercial Mower in good operating
condition for your safety. An improperly main-
tained unit can be hazardous.
4. Keep open flame away from battery or cold
weather starting aids to prevent fires or explo-
sions. Use jumper cables, according to instruc-
tions, to prevent sparks which could cause explo-
sion.
5. Before servicing, park the unit on a firm, level sur-
face and apply the parking brake. Remove the
key to prevent accidental start-up.
6. Escaping hydraulic/diesel fluid under pressure
can penetrate the skin, causing serious injury.
• Do not use your hand to check for leaks. Use a
piece of cardboard or paper to search for leaks.
• Stop the engine and relieve pressure before con-
necting or disconnecting lines.
• Tighten all connections before starting the en-
gine or pressurizing lines.
• If fluid is injected into skin, obtain medical atten-
tion immediately or gangrene may result.
7. Do not modify, alter, or permit anyone else to
modify or alter this unit or any of its components,
or any unit function without first consulting your
New Holland Dealer.
8. SECTION 00 - GENERAL INFORMATION
00-6
SAFETY PRECAUTIONS
8. The fuel oil in the injection system is under high
pressure and can penetrate the skin. Unqualified
persons should not remove or attempt to adjust
a pump, injector nozzle, or any other part of the
fuel injection system. Failure to follow these in-
structions can result in serious injury.
9. Some components on your Commercial Mower,
such as gaskets, may contain asbestos. Breath-
ing asbestos dust is dangerous to your health.
You are therefore advised to have any mainte-
nance or repair operations on such components
carried out by an authorized New Holland Dealer.
If, however, service operations are to be under-
taken on parts that contain asbestos, the essen-
tial precautions listed below must be observed:
• Work out of doors or in a well ventilated area.
• Dust found on the unit or produced during work
on the unit should be removed by extraction, not
by blowing.
• Dust waste should be dampened, placed in a
sealed container and marked to ensure safe dis-
posal.
• If any cutting, drilling, etc., is attempted on mate-
rials containing asbestos, the item should be
dampened and only hand tools or low speed
power tools used.
10. Continuous long term contact with used engine
oil has caused skin cancer in animal tests. Avoid
prolonged skin contact with used engine oil.
Wash skin promptly with soap and water.
11. Do not work under a raised attachment unless it
is securely supported by a suitable hoist or floor
jack and multiple jack stands.
12. The ROPS and seat belt must be properly main-
tained and must not be modified, drilled, or al-
tered in any way. If the ROPS is damaged, if must
be replaced and should not be straightened or
welded.
DRIVING THE COMMERCIAL MOWER
1. Watch where you are going, especially at row
ends, on roads, around trees and low hanging
obstacles.
2. To avoid upsets, drive the Commercial mower
with care and at speeds compatible with safety,
especially when operating over rough ground,
when crossing ditches or slopes, and when turn-
ing corners.
3. Keep the unit in the same gear when going down-
hill as used when going uphill. Do not coast or
free wheel down hills.
4. When the unit is stuck or tires are frozen to the
ground, go up forward to prevent upset.
5. Always check overhead clearance, especially
when transporting the Commercial Mower.
6. Avoid quick stops, especially when an attach-
ment is raised or not installed. Quick stops can
cause upsets.
7. Do not attach chains or ropes to the ROPS for
pulling purposes.
OPERATING THE POWER TAKE OFF (PTO)
Before installing or using PTO-driven equipment,
read the manufacturer’s manual and review the
safety labels attached to the equipment.
1. When operating PTO-driven equipment, shut off
the engine and wait until the PTO stops before
getting off the unit and disconnecting the equip-
ment.
2. Do not wear loose clothing when operating the
power take-off or when near rotating equipment.
3. When operating stationary PTO-driven equip-
ment, always place the gear shift lever in neutral,
apply the parking brake and block in front wheels
front and back.
4. To avoid injury, do not clear, adjust, unclog or ser-
vice PTO-driven equipment when the tractor en-
gine is running.
9. SECTION 00 - GENERAL INFORMATION
00-7
SAFETY PRECAUTIONS
OPERATING THE MOWER DECK
1. Release the Commercial Mower HST foot pedal,
apply the parking brake, place PTO lever in the
“OFF” position, the lift control lever in neutral
position and the transmission in neutral before
starting the engine.
2. Do not start the engine or operate controls while
standing beside the unit. Always sit in the seat
when starting the engine or operating controls.
3. Do not bypass the neutral safety start switch.
Consult your New Holland Dealer if your neutral
safety start controls malfunction.
4. Use jumper cables only in the recommended
manner. Improper use can result in the unit run-
ning away.
5. Avoid accidental contact with the gear shift lever
while the engine is running.
6. Do not get off the Commercial Mower while it is
in motion.
7. Disengage the PTO, shut off the engine and ap-
ply the parking brake before getting off the unit.
8. Do not park the Commercial Mower on a steep in-
cline.
9. Do not operate the engine in an enclosed build-
ing without adequate ventilation. Exhaust fumes
can cause death.
10. If the engine operates erratically, stop the engine
immediately.
11. Do not leave equipment in the raised position.
12. Do not operate the Commercial Mower or any at-
tachments while under the influence of alcohol,
medication, controlled substances or when tired.
13. Do not operate near ditches, holes, embank-
ments or any other terrain which may collapse
under machine weight. The risk of machine tip-
over increases when the ground is loose or wet.
14. When working in cooperation with other opera-
tors, always let others know what you are doing
ahead of time.
15. Never try to mount or dismount from a moving
unit.
16. Do not operate the Commercial Mower with bare
feet. Keep hands, feet and clothing away from
power-driven parts.
17. Do not drive the machine on streets or highways.
Watch for traffic when you cross roads or operate
near roads.
18. Look to the rear before and when backing. You
must disengage blades before shifting into re-
verse. Make sure that the area immediately be-
hind you is clear of obstructions or holes and
small children. Use extra caution when the ma-
chine is equipped with a grass catcher.
19. Do not cross gravel roads with the PTO engaged.
20. Do not operate the mower deck without locking
the hood and seat.
21. Disengage power to the mower deck when trans-
porting or when not in use.
22. Disengage power to the mower deck before
backing up. Do not mow in reverse unless abso-
lutely necessary and then only after careful ob-
servation of the entire area behind the mower
deck.
23. When mowing proceed as follows:
a. Mow only in daylight or in good artificial
light.
b. Never make a cutting height adjustment
while the engine is running if the operator
must dismount to do so.
c. Check the blade mounting bolts for proper
tightness at frequent intervals.
d. Shut off the engine when removing the
grass catcher or clearing the chute.
24. Watch for holes in the terrain and other hidden
hazards.
25. Do not stop or start suddenly when going uphill
or downhill. Mow up and down the face of steep
slopes, never cross the face.
26. Disengage power to attachment(s) and stop the
engine before leaving the operators position.
27. Never leave equipment in the raised position.
28. Always keep the discharge side of the cutter di-
rected away from people and objects which could
be struck by debris thrown from the cutter.
29. Install Commercial Mower weights to increase
stability when operating on slopes.
10. SECTION 00 - GENERAL INFORMATION
00-8
SAFETY PRECAUTIONS
30. Avoid quick stops especially when the mower
deck is raised. Quick stops will cause upset.
31. Keep all shields in place.
32. Replace safety and warning decals when they
become illegible.
33. The vehicle and attachments should be stopped
and inspected for damage after striking a foreign
object and the damage should be repaired be-
fore restarting and operating equipment.
34. Do not lubricate or make mechanical adjust-
ments while the unit is in motion or when the en-
gine is running. However, if minor engine adjust-
ments must be made, apply the parking brake
securely, block the wheels and use extreme cau-
tion.
35. Periodically maintain the mower deck. Tighten
nuts, bolts and fittings periodically for safe opera-
tion. Check the blade for tightness.
DIESEL FUEL
1. Under no circumstances should gasoline, alco-
hol or blended fuels be added to diesel fuel.
These combinations can create an increased fire
or explosive hazard. Such blends are more ex-
plosive than pure gasoline in a closed container
such as a fuel tank. Do not use these blends.
2. Never remove the fuel cap or refuel with the en-
gine running or hot.
3. Do not smoke while refuelling or when standing
near fuel.
4. Maintain control of the fuel filler pipe nozzle when
filling the tank.
5. Do not fill the fuel tank to capacity. Allow room for
expansion.
6. Wipe up spilled fuel immediately.
7. Always tighten the fuel tank cap securely.
8. If the original fuel tank cap is lost, replace it with
an approved cap. A non-approved, proprietary
cap may not be safe.
9. Keep equipment clean and properly maintained.
10. Do not drive equipment near open fires.
11. Never use fuel for cleaning purposes.
12. Arrange fuel purchases so that winter grade fuels
are not held over and used in the Spring.
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin
causing serious injury. Relieve pressure before
disconnecting hydraulic or other lines. Tighten all
connections before applying pressure. Keep hands
and body away from pinholes and nozzles which
eject fluids under high pressure. Use a piece of
cardboard to search for leaks.
If ANY fluid is injected into the skin it must be
surgically removed within a few hours by a doctor
familiar with this type of injury or gangrene may
result.
Whenever you see this symbol it means: WARNING!
BECOME ALERT! YOUR SAFETY IS INVOLVED!

DESCRIPTION OF OPERATION
General
MC model tractors are equipped with three-cylinder
inline diesel engines. These engines are all four
cycle, overhead valve, liquid cooled engines. These
engines are mechanically fuel injected by an injec-
tion pump and fuel injectors. Each cylinder has an in-
jector, for a total of three. Due to the placement of the
fuel tank, a small, inline electric fuel pump assists fuel
delivery to the fuel injection pump. The cooling sys-
tem utilizes and engine mounted water pump that cir-
culates coolant through the engine and radiator. A
thermostat is used to direct coolant flow. The engines
in the MC model tractors are similar and therefore uti-
lize similar repair procedures.
Each model’s engine is identified by a code, 1, which
is cast into the lower right side of the cylinder block.
NOTE: The numeric value, 2, listed under the engine
code indicates the displacement of the engine, in
liters.

Cylinder Block
The cylinder block assembly houses the pistons,
connecting rods, crankshaft, timing gears, camshaft,
and the engine oil pump. The crankshaft is supported
by four main bearings. The first bearing is positioned
in a bore in the front of the block. The second, third
and fourth bearings are split and are held in place by
holders bolted to the engine block. The connecting
rods are bolted to the crankshaft and spin on split
bearings between the crankshaft and connecting
rods. The connecting rods are attached to the pis-
tons, which move up and down inside the block. The
camshaft utilizes two ball bearings, one on each end
of the camshaft, which ride on the inside of the block.
Cylinder head and Valve Train Components
The cylinder head contains the valve assemblies, the
rocker arms and rocker arm shaft, push rods and lift-
ers. The fuel injectors and glow plugs are also
housed in the cylinder head. A swirl chamber located
between the injector assemblies and the main com-
bustion chambers of the cylinders provides improved
starting and better fuel efficiency. Initial fuel combus-
tion begins in the pre-combustion chamber, which in
turn creates a strong swirl pattern into the main com-
bustion chamber. This aids in complete combustion
of the air-fuel mixture. The MC 22 valve cover also
serves as a pre-combustion chamber/air intake man-
ifold, whereas the valve cover on the MC 28 and 35
is separate from the pre-combustion chamber/air in-
take manifold. The exhaust manifold is bolted to the
left side of the cylinder head.
The cylinder head also uses integral valve
guides and standard size valves only for ease of
replacement.
