Contact your Lastec dealer for the proper belt lengths for your Articulator. If you are unable to install a new belt with the pump pivoted to its closest proximity to the engine drive pulley, it is likely you are installing the wrong size belt.
Initial Set-Up Gearbox Be sure that each pump tensioning spring is properly installed and in good condition. If for some reason this spring becomes loose, detached, or fatigued, the pump mount will not properly tension the belt. 3.12 Gearbox CAUTION! Be sure to use the correct fluid in the gearbox! ...
Initial Set-Up Gearbox Alignment 3.14 Gearbox Alignment It is important that the gearbox pulleys are cor- rectly aligned. If the pulleys are not aligned, it will result in over-tensioning and premature belt failure. To check the alignment of the gearbox pulley, use a straight edge.
If the belt you are check- ing is new, and the idler tensioner goes to its maximum stroke without adequately tightening the belt, it is likely you have installed the wrong size belt. Contact your Lastec dealer for the proper belt lengths for your Articulator.
Page 44
Initial Set-Up Leveling the Belt Leveling the Belt To prevent premature wear on the drive belt, a level routing of the belt between the gear- box and deck pulleys should be maintained. Operation of the deck is not effected by the pulley position, but belt wear can be.
If the belt you are check- ing is new, and the idler tensioner pivots to its maximum stroke without adequately tightening the belt, it is likely you have installed the wrong size belt. Contact your Lastec dealer for the proper belt lengths for your Articulator.
Always replace any damaged, dull, cracked, or missing blades before operating the Artic- ulator. Lastec also offers low-lift blades and mulching blades for certain mowing applications. Contact your Articulator dealer for further information about optional blades available. 3-16...
Initial Set-Up Operator Seat 3.18 Operator Seat Check that the operator seat pan is properly latched and operator seat is secure. Be sure the seatbelt is secure and operable. Adjust the seat forward or back so that the operator can easily reach the control panel, steering control arms, and mower deck height adjustment pedal.
NEVER attempt to change the cutting deck height while the engine is running! Caution The Articulator 3682 has a mower deck height range of 1" to 5", in 1/4" increments. If you wish to change the deck height, do so before attempting to operate the Articulator.
Initial Set-Up Mower Deck Height Calibration be the same on all rockers. Replace the deck height adjustment handle back into the stor- age position located behind the operator seat. Make the necessary adjustments to the middle deck pulleys and gearbox spacers according to section 3.15. 3.21 Mower Deck Height Calibration WARNING! NEVER make any adjustments to the deck height while the engine is running!
Initial Set-Up Tires and Wheels 3.22 Tires and Wheels All tires are foam filled with the exception of the rear drive tires. Check the air pressure in the rear drive tires. Maintain air pressure at 18 PSI. Verify proper function of all mower deck wheels. The wheels should turn freely without excessive side-to-side motion, and be free of debris.
Initial Set-Up Battery 3.24 Battery WARNING! EXPLOSIVE GAS! Batteries produce explosive hydrogen gas while being charged! Warning Always charge batteries in a well-ventilated area! Keep all batteries out of the reach of children! See Section 2.9 Use Caution When Working With Batteries.
Initial Set-Up Engine 6. Turn the key switch clockwise to the START position, and start the engine. If the battery charge is not sufficient to crank the engine, charge the battery.

Operating Procedures Starting The Engine Starting The Engine DANGER! NEVER allow extended running of any engine indoors! Exhaust gasses contain car- bon monoxide, an odorless and deadly poison! Danger NEVER operate the Articulator when children are present! WARNING! NEVER attempt to operate the Articulator until you have read and understand this ...
Operating Procedures Stopping The Engine The operator-presence switch (located within the operator seat) and the neutral start switches (located on the steering control arms) must all be activated in order to start the engine. If the operator seat is not occupied, either steering control arm is not locked into neutral position, or the parking brake is not in the ON position, you cannot start the engine.
ALWAYS wear the seatbelt when operating the Articulator! The Articulator 3682 is equipped with two hydrostatic 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).
Page 61
Operating Procedures Motion Control 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 center of the unit until they are free from the neutral lock. You are now ready to begin maneuvering the Articulator.
Operating Procedures Recommended Blades Recommended Blades Ultra Low Blade (Part No. 063265 for 21” Blade and 063266 for 25” Blade) Use Ultra Low Lift Blade when the conditions are dry and in sandy soil areas. When con- ditions like this are evident, lift created by the cutter blades can be reduced, decreasing the abrasion wear to the cutter blades and deck caused by sand.
Ground Speed Ground Speed The Articulator 3682 is 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.
Lifting the cutting deck into transport position while the blades are engaged can cause serious damage to the Articulator! Caution The Articulator 3682 is equipped with an electric deck lift arm which lifts the deck of the unit into the trans- Operate Main Controls From Operator Seat ONLY port/service position.
NEVER operate the Articulator when children are present! The Articulator 3682 is equipped with an 82" wide mower deck, which is comprised of four independently articulating 21" decks. All four decks are belt driven - the drive belt (located under the operator seat pan between the gearbox and the main deck) drives the main deck, and the deck belts (running between the decks) drive each deck.
Operating Procedures Anti-Scalp Wheel Adjustment NOTE: Leaving the operator seat at any time while the blades are engaged will cause the blades to automatically disengage. Blades will shut off automatically if overheating occurs. Anti-Scalp Wheel Adjustment The rear anti-scalp wheel on the deck can be readjusted as needed. 360128-2 IMPORTANT! Any time the mower deck height is adjusted on the Articulator, it is neces- sary to check all the anti-scalp wheels for proper positioning.
