Work safely! Follow all safety rules! A careful operator is the best
insurance against accidents!
Some illustrations in this manual show the Articulator with safety covers removed in order
to provide improved viewing of the particular components being discussed. This is for
informational purposes only -- never operate the Articulator with any of the safety
covers removed!
Safety is a primary concern in the design and manufacture of all LasTec products. Unfortunately, our extensive efforts to provide safe equipment can be negated by a single careless act of an operator. In addition to the design and configuration of the Articulator,
hazard control and accident prevention are also dependent upon the awareness, concern, prudence and proper training of all personnel involved in the operation, transportation, maintenance, and storage of the Articulator. The Best Safety Device is an
informed, careful Operator! We ask you to be that kind of operator.

SECTION 3 Initial Set-Up
3.1
Assembly
The Model 425D Articulator requires a minimum amount of assembly before operation.
Follow the steps below to assemble the Articulator: (You may find it easier to assemble
the Articulator while it is still on the skid).
1. Remove the loose deck (deck 1) and the rocker assembly from the skid.
2. On deck 1, remove the tie wraps which are retaining the bushings in the deck pivot plates,
and in the rocker mount tube.
3. On the drive unit, remove the tie wraps which are retaining the deck belt and deck lift
cable.
4. Remove the 3/4” pin weldments & hardware, and 1/2-13 x 3 bolts and nuts from the pivot
plates on the deck assembly (deck 4).
5. Install deck 1 onto the deck assembly. Slide the pivot plates on deck 1 between the pivot
plates on deck 4, and slide the trap door (the zinc plated plate located under the rubber
flap) UNDER the edge of deck 4, with the rubber flap riding ON TOP of deck 4. Block up
deck 1 to keep it parallel with deck 4 during assembly. Re-install 3/4” pins and hardware,
and 1/2-13 x 3” bolts and nuts into front & rear pivot plates. Tighten all hardware. (You
may find it easier to install the rear pivot pin if you lift the rear wheel for greater clearance).
6. Install the deck belt from deck 4 to deck 1. Route the front of the belt around the spindle
pulley on deck 1, then wrap the flat side of the belt back around the flat-faced idler pulley,
then the bevel side of the belt back around the grooved idler pulley, and the back of the
belt returns to deck 4. (Refer to the deck belt illustration in the parts manual for greater
detail).
7. Remove the loose 1” pin weldment & hardware from the rocker assembly.
8. Mount the rocker assembly to deck 1, with the swivel wheel to the front of the deck. Align
the pivot plates on the rocker assembly with the mount collar on the deck. Re-install the
pin weldment and hardware into the rocker mount collar. Tighten all hardware.
9. Mount the rocker pivot limit weldment (on the rear of the rocker assembly) between the
two tabs on deck 1, secure with the clevis pin and hitch pin.
10. Install the deck 1 belt cover using the wing nut and fender washer on the deck.

Initial Set-Up
Parking Brake
11. The deck lift cables are factory calibrated. The adjustment nuts on the deck 1 cable are
locked into position during shipping, eliminating the need for adjustment after re-assembly. Simply install the cable into the mount plate on the side of the rocker assembly. Seat
the locked jam nuts against the back of the plate, and tighten the third nut to the front of
the plate. Attach the cable eyelet to the fork located to the front of the rocker assembly,
and secure with the clevis pin & cotter pin.
12. Attach the hydraulic lift arm between the two mount plates on deck 1, secure with 3/8-16
bolt & hardware.
13. Install the 3 anti-scalp wheels into the bracket on the rear of deck 1. Secure with 1/2-13 x
1” bolts & lock washers. (The anti-scalp wheels & mounting hardware are located in the
utility box to the right rear of the drive unit).
14. Attach the rear stabilizer between the two plates on the rear of deck 1. Secure ball swivel
end with 3/4” clevis pin & hitch pin.
3.2
Parking Brake
ALWAYS set the parking brake before performing any set-up,
inspection, adjustments, or maintenance to the Articulator!
ALWAYS release the parking brake before operating the Articulator!
The parking brake is located to the left of the operator seat, just in front of the left steering
control arm. To set the parking brake, grasp the handle and pull upward, increasing the
brake tension, until the tension prevents any further travel of the handle. The ratchet gear
will lock the handle into position.
If, while the parking brake is set, the key switch is turned to the RUN or START position,
the parking brake indicator light will come on (the red light located to the upper right corner of the control panel), and an audible warning beeper will sound. This is to warn you
that the brake is set, and you should release the brake before attempting to operate the
Articulator. Releasing the parking brake will deactivate both the indicator light and the
warning beeper.
To release the parking brake, pull upward on the handle to relieve the brake tension,
depress the button on the end of the handle, and slowly return the handle all the way
down to its original position.

The Model 325D/425D Articulator is equipped with an 8-gallon fuel tank, which is located
behind the left fender. The Articulator is shipped dry (no fuel) from the factory, so you will
need to fuel the Articulator before operating. The fuel tank cap also serves as a gauge
indicating the fuel level in the tank. Do not attempt to fuel the Articulator until you
read and understand the entire INITIAL SET-UP section of this manual.
Diesel Fuel: Use only No. 2 diesel fuel oil. Do not use any other alternative fuel. Kerosene and low quality diesel fuel oil will adversely affect the engine. Always use a strainer
when filling the fuel tank. Contaminants in the fuel can adversely affect the fuel injection
pump.
Do not allow the fuel tank to drain completely of fuel. This can allow air into the fuel system. If this happens, the fuel system will have to be bled before restarting the engine.

need to replace the battery.
If changing the battery, be sure all control switches are in the OFF position before disconnecting the negative (-) ground cable. Otherwise, sparking and explosion are possible!
Batteries produce explosive hydrogen gas while being charged. To prevent fire or explosion, only charge batteries in well-ventilated areas, away from any spark, open flame, or
other sources of ignition. Always remove jewelry before handling batteries. Keep all batteries out of the reach of children!
Use extreme care to avoid spilling or splashing electrolyte (which is dilute sulfuric acid) as
it can destroy clothing and burn the skin. If electrolyte is spilled or splashed on clothing or
the body, it should be neutralized immediately and then rinsed with clean water. A solution of baking soda, or household ammonia, and water may be used as a neutralizer.
Electrolyte splashed into the eyes is extremely dangerous. If this should happen, force
the eye open and flood it with cool, clean water for approximately fifteen minutes. A doc3-16

tor should be called immediately when the accident occurs and "on-the-spot" medical
attention given if possible. If a doctor cannot come to the scene of the accident immediately, follow his instructions concerning actions to take. Do not add eye drops or other
medication unless advised to do so by the doctor. Do not place a battery or acid within the
reach of children. If acid (electrolyte) is taken internally drink large quantities of water or
milk. Follow with milk of magnesia, beaten egg or vegetable oil. Call a physician immediately. If electrolyte is spilled or splashed on any surface, it should be neutralized and
rinsed with clean water.1
3.27 Engine
While the engine is running, check the color of the exhaust. During proper operation, the
exhaust should be colorless. If the engine runs continuously with dark exhaust, stop the
engine and correct the problem before operating the Articulator.
Listen for any unusual engine noises. If the engine suddenly slows down or accelerates,
or is making any abnormal noises, running roughly or displaying any other usual characteristics, stop the engine and correct the problem before operating the Articulator.
Check the oil pressure and water temperature indicator lights (the center and left red
lights located at the top of the control panel). These lights will indicate an inadequate
engine oil pressure, or an excessive engine coolant temperature. If either light is activated while the engine is running, stop the engine and correct the problem before operating the Articulator.
3.28 Mower Deck Lift
NEVER attempt to lift the cutting deck into transport position while the
blades are engaged! Lifting the cutting deck into transport position
while the blades are engaged can cause serious damage to the
Articulator!
The Model 425D Articulator is equipped with both a manual deck lift lever (on the right
side) and a hydraulic deck lift arm (on the left side). The 325D Articulator is equipped with
manual deck lift levers on both sides, and does not include the hydraulic deck lift.
On the 425D, test the operation of the hydraulic deck lift arm while the engine is running.
Be sure the blades are NOT engaged. Never lift the mower deck into transport position
while the blades are engaged.
The hydraulic deck lift arm is operated with the foot pedal located on the front left of the
frame, to the left of the deck height adjustment pedal. From the operator seat, slowly
depress the TOP of the foot pedal, activating the hydraulic deck lift cylinder. The arm
should retract, lifting the left side of the mower deck slightly off the ground and locking

pressure on the foot pedal.
Once you have determined that the hydraulic deck lift arm is both lifting and locking the
mower deck properly, SLOWLY depress the BOTTOM of the foot pedal to release the
hydraulic deck lift cylinder. If you are preparing to travel to the cut site, you may wish to
leave the hydraulic deck lift arm locked into transport position. Turn off the engine.
Adjust the manual deck lift lever(s). The manual deck lift lever(s) lift the mower deck into
transport position (right side on 425D, both sides on 325D). The lift levers are located to
the right (325D & 425D) and left (325D only) of the operator seat, behind the steering
control arm(s). Pull each deck lift lever toward the operator seat, lifting the mower deck to
transport position. When in transport position, each lever automatically locks into place.
Check to be sure that the lift chain is lifting the deck to the desired height for transport. If
not, adjust it. First, release the deck lift arm by pushing it away from the operator seat.
Then remove the chain link from the hook in the deck lift handle, move the chain up or
down to either tighten or loosen it, and place the chain link back onto the hook.
3.29 Hour Meter
The hour meter is located in the upper left corner of the control panel. This meter records
the total hours on the engine, and is not resettable. You may wish to record the hour
meter reading prior to operation of the Articulator for tracking of maintenance schedules,
job timing, billing, or other records.

SECTION 4 Operating Procedures
4.1
Starting The Engine
NEVER attempt to operate the Articulator until you have read and
understand this manual in its entirety!
NEVER allow anyone to operate the Articulator without proper training
and without first reading and understanding this manual in its entirety!
ALWAYS perform the pre-operation equipment inspection before
attempting to operate the Articulator!
ALWAYS perform the appropriate maintenance schedule(s) before
attempting to operate the Articulator!
NEVER allow extended running of any engine indoors! Exhaust gasses
contain carbon monoxide, an odorless and deadly poison!
NEVER operate the Articulator when children are present!
Upon completion of reading and understanding this manual in its entirety, reviewing all
safety rules, completing the pre-operation inspection checklist, and performing the appropriate maintenance schedule(s), you are ready to begin operating the Articulator.
From the operator seat, be sure all auxiliary switches (blades, lights, etc.) on the control
panel are in the OFF positions and the hand control levers are locked into NEUTRAL
position. Set the parking brake.
The operator present switch (located within the operator seat) and the neutral start
switches (located on the steering control arms) must all be activated in order to crank the
engine. If the operator seat is not occupied, or either steering control arm is not locked
into neutral position, you cannot crank the engine.
Activation of these switches is indicated by the operator present and neutral start lights on
the control panel (the two green lights directly above the key switch). Turn the key switch
clockwise to the RUN position. If both green indicator lights are activated, you are ready
to start the engine.
As with any diesel engine, you must first pre-heat the glow plugs before attempting to
start the engine. To do this:
15. Turn the key switch counter-clockwise to the GLOW position for 9 seconds. After 9 seconds, the audible warning beeper will sound, signifying adequate preheat.
16. Turn the key switch clockwise to START position, cranking the engine for a maximum of
10 seconds.

Operating Procedures
Stopping The Engine
17. If the engine does not start within 10 seconds, discontinue cranking by turning the key
switch counter-clockwise to the OFF position. Repeat steps 1 through 3. If, after several
attempts, the engine will still not start, discontinue the starting process until the cause of
malfunction is determined.
18. When the engine starts, adjust the throttle lever (located to the lower right of the operator
seat, behind the right steering control arm) forward until the engine is running at a steady
idle. Do not overpower the engine.
4.2
Stopping The Engine
Stop the engine by throttling down to a slow idle, then turning the ignition key switch to the
OFF position. Wait for all motion to stop. Be sure all auxiliary switches are in the OFF
position. Set the parking brake before dismounting the Articulator.
4.3
Motion Control
ALWAYS clear the entire area of all personnel before operating the
Articulator!
ALWAYS wear the seatbelt when operating the Articulator!
ALWAYS verify that all safety covers are in place and secure before
operating the Articulator!
The Model 325D/425D Articulator is equipped with two hydraulic pumps, one operating
each rear drive wheel. These pumps are controlled separately with each of the steering
control arms (located to the left and right of the operator seat).
Pushing a steering control arm forward activates the hydraulic pump on the corresponding side, turning the drive wheel in the corresponding direction. (i.e., pushing the right
steering control arm forward activates the right drive wheel in the forward direction. Pulling the right steering control arm back activates the right drive wheel in the reverse direction.)
The steering control arms also govern the ground speed of the Articulator. The farther
from the neutral position the arm is pushed or pulled, the faster the corresponding drive
wheel turns. Always use the steering control arms to regulate ground speed - NOT the
throttle control.
Buckle the seatbelt. Always wear the seatbelt when operating the Articulator. Clear the
entire area of all personnel before operating the Articulator. Verify that all safety covers
are in place and secure before operating the Articulator.
Start the engine (refer to the Starting The Engine section of this manual for the proper
procedures).
Release the parking brake. Verify that both the parking brake indicator light (located in

the upper right corner of the control panel) and the audible parking brake alarm are deactivated before attempting any travel with the Articulator.
In order to maneuver the Articulator, you must first remove both steering control arms
from the neutral lock position. Simply grasp each steering control arm with each hand,
and pull them both toward the operator seat until they are free from the neutral lock. You
are now ready to begin maneuvering the Articulator. Following are the proper steering
procedures:
4.4
l
To travel forward: Push both control levers forward evenly. The farther they are
pushed, the faster the Articulator travels.
l
To travel in reverse: Pull both control levers backward evenly. The farther they are
pushed, the faster the Articulator travels.
l
To turn to the right: Push the left control lever forward slowly, and maintain the
right control lever in neutral position.
l
To turn to the left: Push the right control lever forward slowly, and maintain the left
control lever in neutral position.
l
To obtain a zero turn radius (ZTR) to the right: Push the left control lever forward
slowly, while simultaneously pulling the right control lever backward slowly.
l
To obtain a zero turn radius (ZTR) to the left: Push the right control lever forward
slowly, while simultaneously pulling the left control lever backward slowly.
l
To stop: Return both control levers to the neutral position.
l
To change directions: Slowly return both control levers to the neutral position, and
allow the Articulator to slow to a stop. Then slowly move the control levers into the
appropriate positions to travel in the desired direction.
l
NOTE: When the control levers are released, they automatically return to the neutral position, stopping all motion of the Articulator.
Ground Speed
The Models 325D & 425D Articulators are designed to cut cleanly and efficiently at relatively high ground speeds. Reduced ground speed is required when operating on severe
contours, when cutting excessively tall, wet, or thick grass, or when traveling up or down
large or steep hills. Maximum ground speed is intended for transport to and from the cutting site only, and should not be attempted during any cutting operation.
Attempting to change directions at high ground speed, whether cutting or transporting,
can cause damage to the turf, especially in wet conditions. Direction changes should be
made by slowing to a near or complete stop (returning the control levers to neutral position), and slowly changing the control lever positions to begin travel in the desired direction. This prevents turf damage, as well as prolonging equipment life and promoting safer
operation of the Articulator.

Operating Procedures
Mower Deck Lift
Mower Deck Lift
NEVER attempt to lift the cutting deck into transport position while the
blades are engaged! Lifting the cutting deck into transport position
while the blades are engaged can cause serious damage to the
Articulator!
Before traveling to the cut site, lift the mower deck into transport position. To lift the
mower deck into transport position, the engine must be running in order to activate the
hydraulics. Be sure the blades are NOT engaged. Never lift the mower deck into transport position while the blades are engaged.
On the 325D, use the manual deck lift levers (located to the left & right of the operator
seat, behind the steering control arms and in front of the fenders). Pulling the levers
toward the operator seat lifts the mower deck off the ground to transport position. The
levers will automatically lock into position.
On the 425D, use the hydraulic deck lift arm pedal (located on the front left of the frame,
left of the deck height adjustment pedal) to lift the left side of the mower deck. Depressing the TOP of the pedal activates the hydraulic cylinder, lifting the left side of the mower
deck off the ground to transport position. The lever locks into position, even after discontinuing activation of the foot pedal.
Once you have reached the cut site, lower the mower deck to cut position by carefully
pushing the right deck lift levers away from the operator seat (325D). On the 425D, lower
the left side of the mower deck to cut position by SLOWLY depressing the BOTTOM of
the hydraulic deck lift arm pedal until the hydraulic cylinder reaches maximum extension.
Avoid releasing the deck lift arm too quickly - resulting in the mower deck hitting the
ground excessively hard.
4.6
Mower Deck Operation
ALWAYS clear area of all personnel before engaging the blades!
ALWAYS verify that all safety covers are in place before operating the
Articulator!
NEVER discharge in the direction of bystanders, vehicles, or buildings!
ALWAYS stay well clear of blades during operation!
NEVER operate the Articulator when children are present!
The Model 425D Articulator is equipped with a 96" wide mower deck, which is comprised
of four independently articulating 25" decks. The 325D is equipped with a 72” mower
deck, which is comprise of three 25” decks. All of the decks are belt driven - the drive belt
(located under the operator seat pan between the gearbox and the center deck) drives
the center deck, and the deck belts (located between the center deck and the other three
decks) drive the other decks. The individual decks pivot at blade level, and the idler belt

tension system takes up excess belt length or releases additional belt length as necessary during the up and down articulation of the decks. This allows the Articulator to hold
the contour of the ground with precision.
Refer to the Initial Set-Up section of this manual for instructions on setting the mower
deck height to the desired level.
The Model 325D/425D Articulator is equipped with an electric clutch which activates the
gearbox, thus engaging the blades of all the decks simultaneously. The blades may only
be engaged while the engine is running.
In order to engage the blades, the operator present switch (located within the operator
seat) must be activated. The activation of the operator present switch is indicated by the
operator present light located on the control panel just above the key switch.
From the operator seat, switch the BLADES toggle switch (located in the center of the
main control panel, above the headlight and hazard light toggle switches) to the START
position. It is a MOMENTARY SWITCH - you may release it immediately upon activation
of the clutch. The blades will engage slowly, and gradually increase in speed until the
maximum RPM is reached.
Leaving the operator seat at any time while the blades are engaged will cause the blades
to automatically disengage.
