Items 21,22,26, 29, 30, 31 and 32 not shown. See figure 1 for installation of 31 and 32. See figure 5 for installation of 29 and 30. See figure 9 for installation of 21 and 22.

• 52” Lazer Z units with serial numbers below 260,000 require the use of adapter kit 103-

1369. Follow the instructions included in the kit when noted in the following steps.

• 72” units below serial number 260,000 require the deck to be modified by adding the accessory mounting tube. Exmark kit 103-0583 contains the parts and templates to do this.

3.2 INSTALL THE HOOD ASSEMBLY AND BAGS

Lazer Z units only (Lazer Z XP units skip to step 6)

1. When installing the Ultra Vac onto a liquid cooled Lazer Z, the rear bumper plate must be removed. Remove rear bumper plate. Use two of the original bolts, washers and whizlock nuts to attach the lower side bumper bars to the vertical “HOT” engine guard shield.

2. Remove the lower two bolts holding the clutch guard plate (“HOT” engine guard on liquid cooled units) to the rear frame of the Lazer Z unit. Units with serial numbers below 160,000 will require disassembly of the clutch strap spacers to remove these bolts.

3. On units with serial numbers above 190,000 install the mount weldment (Item 9) loosely to the rear of the machine using the two bolts and nuts removed in step 2.

For units with serial numbers below 190,000, install washers (Item 31) between the bagger mount weldment and clutch guard when installing the bagger mount weldment. This will provide for proper alignment of the mount holes with the holes in the side plates (see figure

1).

For units with serial numbers below 160,000, remove the two tap bolts that tie the clutch straps to the clutch guard and replace with new tap bolts (Item 32). These units also require the use of the washers (Item 31) between the bagger mount weldment and the clutch guard. These parts should be installed when the bagger mount weldment is installed on the rear of the unit (see figure 1).

4. Jack the rear of the unit up and safely support it on jack stands. Remove the rear wheels.

POTENTIAL HAZARD ♦ Relying solely on mechanical or hydraulic jacks to

support the mower could be dangerous.

WHAT CAN HAPPEN ♦ The mechanical or hydraulic jacks may not be enough

support or may malfunction allowing the unit to fall, which could cause injury.

HOW TO AVOID THE HAZARD ♦ DO NOT rely solely on mechanical or hydraulic jacks

for support. Use adequate jack stands or equivalent support.

FIGURE 1

CAUTION

5. Install the side plates (Items 14 and 15) loosely to the mount weldment and the wheel channels of the Lazer Z frame. The flanges on the side plates should face in towards the unit to provide the maximum tire clearance. Use the 3/8-16 x 1.00 bolts (Item 23), 3/8 spring disk washers (Item 25) and 3/8-16 whizlock nuts (Item 24). Make sure that the raised portion of the spring disk washer faces the head of the bolt. On 52 and 60 inch units, the lower bolt on the wheel channel is best installed by positioning the nut behind the hole using a deep socket and turning the bolt through the hole into the nut.

Lazer Z XP units only (Lazer Z units continue at step 8)

6. Install mount weldment (Item 9) loosely to the rear bumper using the two holes provided. Use the 3/8-16 x 1.00 bolts (Item 23), 3/8 spring disk washers (Item 25) and 3/8-16 whizlock nuts (Item 24).

7. Install the side plates (Item 16) and spacers (Item 17) loosely to the mount weldment and the mounting pads on the Lazer Z XP frame. Use the 3/8-16 x 1.00 bolts (Item 23), 3/8 spring disk washers (Item 25) and 3/8-16 whizlock nuts (Item 24). Make sure that the raised portion of the spring disk washer faces the head of the bolt.

All Units

8. Tighten all the hardware, starting with the bolts that hold the mount weldment to the rear of the unit and working forward.

9. On Lazer Z units, reinstall the rear wheels and lower the unit from the jack stands.

10. Apply a light coat of grease to the front and rear of the upper tube of the mount weldment. Install the hood assembly (Item 7) onto the mount by slipping the hook portion over the top mounting tube of the mount weldment. Secure the assembly to the mount using the clevis pins (Item 19) and hairpins (Item 20).

11. Install the bag assemblies (Item 1) by inserting the hook portion into the slots in the cross bar of the hood assembly.

3.3 INSTALL BLOWER ASSEMBLY

1. Lower the deck fully. Remove the right hand belt cover. Remove the belt cover mounting stud that protrudes from the deck.

2. Remove the deck drive belt from around the right hand spindle sheave.

3. Support the right mower blade and shaft so that it will not fall out of the deck when the right sheave nut is removed.

4. Remove the right sheave nut, spring disk washer, and sheave from the spindle shaft.

NOTE: On units with wrench flats on the spindle just above the blade use a 1-inch wrench on the flat sides of the spindle shaft to prevent the spindle from turning. On units that do not have a wrench flat, block the blade rotation with a block of wood between the blade and baffles as indicated in the blade service section of the Lazer operator’s manual. Do not use the blade bolt to prevent rotation.

5. Some older units may require the replacement of the spindle shaft, depending on the drive kit that is used. (Ref section 2.4). On those units, remove the spindle shaft / blade assembly from the mower. Transfer the blade from the original shaft to the new spindle shaft and reinstall the assembly onto the mower.

6. Apply a light coat of grease to the top portion of the spindle shaft where the sheave mounts.

7. Install the double sheave (Item 12) onto the right spindle shaft. Install the spring disk washer and nut. Make sure that the spring disk washer cone is installed towards nut (see figure 2). Torque the sheave nut to:

5/8 - 11 nut (15/16 Hex) - 75-80 ft. lbs.

3/4 -16 nut (1 ¼ Hex) – 140-145 ft. lbs.

NOTE: On units with wrench flats on the spindle just above the blade use a 1-inch wrench on the flat sides of the spindle shaft to prevent the spindle from turning. On units that do not have a wrench flat, block the blade rotation with a block of wood between the blade and baffles as indicated in the blade service section of the Lazer Z operator’s manual. Do not use the blade bolt to prevent rotation. Check blade bolt torque after completing this installation (115 – 120 ft. lbs.).

FIGURE 2

8. Re-install the deck drive belt in the lower groove of the double sheave. Install the plug (Item 24) into the bore of the double sheave.

9. Remove the discharge chute from the deck. Discard the mounting hardware, but save the discharge chute for use during side discharge operation. The chute pivot pin (Item 21) and hairpin (Item 22) may be stored in the pivot holes on the discharge chute during bagging operation.

52 inch units only (60 and 72 inch units skip to step 17)

10. Remove the belt guide on the blower (see figure 3)

11. Install the belt (Item 13) included in the completing kit onto the blower assembly as shown.

12. Reinstall the belt guide removed in step 9.

13. If the Ultra Vac is being installed on a Lazer Z with a serial number less than 260,000, it is recommended to replace the steel blocker plate mounted across the bottom of the blower

FIGURE 3

BELT ROUTING

with the small filler plate included in the completing kit (Item 26). Use the hardware that was removed when removing the large blocker plate (see figure 4). Failure to install a

blocker plate will create a thrown object hazard that could injure or kill bystanders, or cause property damage. This modification should not be done if the Ultra Vac blower

will be mounted on a Lazer Z with a serial number of 260,000 or higher.

FIGURE 4

LAZER Z 52 UNITS WITH SERIAL NUMBERS

LESS THAN 260,000 ONLY

14. The front right deck stiffener must be trimmed for belt clearance on 52” Lazer Z units with serial numbers less than 220,000. Measure and mark the deck stiffener (see figure 5). Trim off the indicated portion of the stiffener. Touch up the trimmed area with Exmark red touchup paint – P/N 1-850337.

Using the knob that was removed with the original belt cover stud and the knob included with the completing kit (Item 40), mount the two belt cover supports (Item 39) to the plastic belt cover (Item 10). Position the belt cover on the mower deck. The lower ends of the belt cover supports should rest on the outside of the deck stiffeners. Mark the location of the belt cover support holes on the deck stiffeners. Remove the belt cover. Center punch and drill 3/8” holes.

15. Remove the belt cover supports from the belt cover and mount them to the deck using the 5/16-18 x .75 screws (Item 41) and whizlock nuts (Item 38).

16. Units with serial numbers below 260,000 will require modifications to the discharge chute tabs per the instructions in adapter kit 103-1369. Follow the instructions included in the kit before proceeding with the blower installation.

60 and 72 inch units only (52 inch units continue at step 21)

17. Install the belt cover mounting stud (Item 27) included in the Ultra Vac completing kit.

For 60 inch units only, install the spacer (Item 29), two 7/16 spring disk washers (Item 30) and the plastic knob (see figure 6). The knob does not need to be tightened against the washers at this time.

FIGURE 6

18. Install the mounting pin weldment (Item 18) to the blower assembly using the 3/8-16 x .75 bolts (Item 28) and whizlock nuts (Item 24). Maximum deck clearance will be provided if the bolts are installed from below the mounting pin. The mount pin can be installed in two positions. For 60 inch decks the pin should be installed as far away from the bumper end as possible. For 72 inch decks that pin should be installed close to the bumper end (see figure 7).

FIGURE 7

19. Install the belt (Item 13) onto the blower by working it around the impeller sheave.

20. 72” units below serial number 260,000 will require the deck to be modified by adding the accessory mounting tube. Exmark kit 103-0583 contains the parts and templates required. Follow the instructions in this kit. These decks will also require drilling the hole at the front upper corner of the discharge opening to ½ inch diameter (see figure 8). Touch up with red paint Exmark P/N 850337.

All units

21. Mount the blower on the deck by sliding the mounting pin into the tube at the rear right corner of the deck. Swing the blower closed. Adjust the position of the front pin to engage the slot in the front of the deck. Use the latch to lock the blower in this position. Adjust the tension on the latch to hold the blower up to the deck, yet allow for release by hand.

22. Pull the spring loaded idler back and slip the belt over the top sheave on the deck spindle.

23. Install the plastic belt cover (Item 10). On 60” units the outside end of the cover is slotted and can slip between the two washers assembled in step 17. The plastic knob does not need to be removed. On 72” and 52” units the cover has a hole, and the plastic knob must be installed after the cover has been positioned. The original belt cover stud must be

removed on 52” units.

3.4 ASSEMBLE THE TUBES

1. Remove the six screws, nuts, and washers (Items 4,5,and 6) from the lower tube (Item 3) and slide the lower and upper tube (Item 2) together. The arrow on the upper tube should align with the dimple on the lower tube. On 60 and 72 inch units there are two sets of holes on the lower tube. The first set reached is for use with Lazer XP units. The second set reached is for Lazer Z units. Align the arrow on the upper tube with the dimple on the lower tube and slide them together until the proper set of holes is reached.

2. Fasten the upper and lower tubes together using three of the hardware sets removed from the lower tube in step 14. The heads of the screws must be inside the tube to prevent accumulation of grass inside the tube. The washer and the nut should be installed on the outside of the tube. On Lazer XP units, use the remaining three hardware sets to plug the exposed holes in the lower tube. On Lazer Z units, discard the remaining hardware sets.

3. Slip the upper end of the tube assembly into the hood opening. Slide the lower end of the

tube assembly over the blower outlet and align the notch with the tube latch. Latch the tube to the blower.

3.5 INSTALL THE WEIGHT PLATES

1. The four weight plates (Item 35) must be installed under the front panel of the floor pan.

These weights give proper balance to the machine when the removable portions of the bagger are removed.

2. Locate the position of the mounting holes. On some machines the hole positions are

indicated by tool marks on the floor pan. Most machines will require clamping a weight plate to the front of the floor pan (see figure 9). The ears on the weight plate should be towards the bottom (upside down from the actual mounted position). Align the bottom edge of the weight plate with the bottom edge of the floor pan front panel. Center the weight plate side to side. Mark the position of all four holes using a center punch.

3. Drill 3/8 inch holes at the points marked.

4. Open the floor pan and install the four weight plates behind the front panel using the 5/16-

18 x 1.50 screws, 5/16 washers and 5/16-18 whizlock nuts (Items 36, 37, and 38). The weight plates will only fit with the ears located near the bend in the floor pan. The decal on the outside of the floor pan will still be visible with the weight plates mounted.

4. Tighten knob on weight assembly until the weight is

clamped securely to the caster arm.

3.7 RUN IN – 52” UNITS ONLY

1. Follow the operation instructions in Section 5 to run the unit. Run the unit with the blades and blower engaged for 2 minutes. Disengage the blades, stop engine and wait for all moving parts to stop. Remove key.

2. Remove the belt cover and check to make sure that the belt is riding near the center of the flat idler on the idler arm. If the belt is not riding near the center of the idler, remove the blower, and bend the idler arm slightly. Reinstall the blower and belt cover and perform steps 1 and 2 again to verify belt position.

4. OPERATION:

Although hazard control and accident prevention are partially dependent upon the design and configuration of the equipment, these factors are also dependent upon the awareness, concern, prudence, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the equipment. It is essential that all Operator Safety Mechanisms be connected and in operating condition prior to use for mowing. Refer to the Operator’s Manual for the mower for additional hazard control and accident prevention information.

WARNING

POTENTIAL HAZARD ♦ An uncovered discharge opening will allow objects to

be thrown in operator’s or bystander’s direction. Also, contact with blade could occur.

WHAT CAN HAPPEN ♦ Thrown objects or blade contact can cause serious

injury or kill you or bystanders.

HOW TO AVOID THE HAZARD ♦ Never operate mower unless discharge chute or

entire grass collection system is installed.

DANGER

POTENTIAL HAZARD ♦ There are rotating blades in the blower and under

the mower deck.

WHAT CAN HAPPEN ♦ Blade contact can cause serious operator or

bystander injury or even death.

HOW TO AVOID THE HAZARD ♦ Keep hands and feet out of blower openings and out

from under the mower or mower deck.

♦ Shut off the deck drive, stop the engine, and wait for

all moving parts to stop before clearing obstructions.

4.1 PRE-START

Note: When mowing in areas with sandy soil, use low lift blades on the cutting deck and higher cutting heights to minimize wear on the blower components.

1. Read the operator’s manual for your mower and familiarize yourself with all controls before operating the machine. Make sure that you understand the controls, their locations, their functions, and their safety requirements.

2. Ensure the blower, belt cover, bags, tube and hood are in good condition, properly attached, and latched.

4.2 MOWING

1. The Ultra Vac blower operates when deck drive is engaged. Be sure that all persons are clear of the mower deck and blower before engaging the cutting blades. Set the throttle

to “midway” position. Pull outward on the PTO switch to the “ROTATE” position. Accelerate to full throttle to begin mowing.

2. To disengage the deck drive and blower, set the throttle to “midway” position. Push in on the PTO switch to the “STOP” position to stop the cutting blades and blower. The cutting blades will require a slightly longer amount of time to come to a complete stop when the blower is installed on the deck.

3. To remove the bags, shut off deck drive, stop the engine and wait for all moving parts to stop. Open the hood and remove the bags by lifting up on the rear of the bag, then unhooking the front clip. Empty bags by inverting them.

4. Reinstall bags, close and latch the hood before continuing mowing.

4.3 BAGGER REMOVAL FOR SIDE DISCHARGE:

1. Shut off the deck drive, stop engine and wait for all moving parts to stop. Remove key.

2. Remove the discharge tube by releasing the latch at the blower. Slide the tube off the blower outlet and remove the upper end from the hood.

3. Remove the Belt cover by loosening the knobs. For 60” units the outboard knob does not need to be removed completely to remove the belt cover.

CAUTION

POTENTIAL HAZARD ♦ The deck sheave will become very hot

WHAT CAN HAPPEN ♦ Touching a hot deck sheave can cause severe burns.

HOW TO AVOID THE HAZARD ♦ Allow the deck sheave to cool completely before

removing the belt.

4. Pull the idler release handle and remove the belt from the upper groove of the deck sheave.

5. Unlatch the front end of the blower. Pivot the blower back and lift it off the deck.

6. Install the discharge chute using the chute pivot pin and hairpin (see figure 11).

FIGURE 11

DISCHARGE CHUTE INSTALLATION

7. Re-install the plastic belt cover and tighten the knobs.

8. Remove the hair pins and clevis pins holding the hood assembly to the mount weldment.

9. Lift the bag and hood assembly off the mount.

10. The removable weights must be removed from above the caster wheels. Loosen the clamping knobs until the weight can be moved relative to the caster arm. Remove the hairpins and clevis pins that hold the weights to the caster arms. Carefully lift the weights off of the caster arms.

Note: The removable weights are heavy. Use care when lifting them. Make sure that

you can hold them securely before lifting them. Use caution when positioning your hands so that you do not set them down on your hands or fingers.

Note: The portions of the Ultra Vac bagger that are not bolted to the mower are

designed to be installed or removed in their entirety. Do not operate the mower with only a portion of the Ultra Vac installed.

CAUTION

POTENTIAL HAZARD ♦ Caster weights installed without bagger may cause

Loss of Traction and Steering control.

WHAT CAN HAPPEN ♦ Loss of control can result in an accident, which may

cause Death, Injury, or property damage.

HOW TO AVOID THE HAZARD ♦ Install caster weights ONLY when bagger is installed.

11. The machine can now be used for side discharge mowing.

4.4 TRANSPORTING

1. Transporting a Unit: Use a heavy-duty trailer or truck to transport the machine. Lock brake and block wheels. Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Be sure that the trailer or truck has all necessary lighting and marking as required by law. Secure a trailer with a safety chain.

CAUTION

POTENTIAL HAZARD ♦ This unit does not have proper turn signals, lights, reflective

markings, or a slow moving vehicle emblem. These items are required to drive on a public street or roadway.

WHAT CAN HAPPEN ♦ Driving on a street or roadway without such equipment is

dangerous and can lead to accidents causing personal injury.

♦ Driving on a street or roadway without such equipment may

also be a violation of State laws and the operator may be subject to traffic tickets and/or fines.

HOW TO AVOID THE HAZARD ♦ Do not drive a unit on a public street or roadway.

WARNING

POTENTIAL HAZARD ♦ Loading a unit on a trailer or truck increases the possibility of

backward tip-over.

WHAT CAN HAPPEN ♦ Backward tip-over of the unit could cause serious injury or

death.

HOW TO AVOID THE HAZARD

♦ Use extreme caution when operating a unit on a ramp. ♦ Use only a single, full width ramp; DO NOT use individual

ramps for each side of the unit.

♦ If individual ramps must be used, use enough ramps to create

an unbroken ramp surface wider than the unit.

♦ DO NOT exceed a 15° angle between ramp and ground or

between ramp and trailer or truck.

♦ Avoid sudden acceleration while driving unit up a ramp to

avoid tipping backward.

♦ Avoid sudden deceleration while backing unit down a ramp to

avoid tipping backward.

2. Loading a Unit: Empty grass bags before attempting to load unit on trailer or truck.

Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is required instead of individual ramps for each side of the unit. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or truck do not exceed 15°. A steeper angle may cause mower deck components to get caught as the unit moves from ramp to trailer or truck. Steeper angles may also cause the unit to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

DO NOT attempt to turn the unit while on the ramp, you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the unit to tip backward.

5. MAINTENANCE:

WARNING

6. Tips and Troubleshooting

Your Exmark Ultra Vac has been designed to be the most productive bagging system on the market. The following tips have been collected to help you get the most out of your Ultra Vac right from the start.

6.1 When mowing in areas with sandy soil, use low lift blades on the cutting deck and higher cutting heights to minimize wear on the blower components.

6.2 When mowing in wet conditions, such as just after a rain or in heavy dew, use low lift blades on the cutting deck to minimize plugging of the blower.

6.3 When the bags get full, the sound of the blower will change and there will be slight blowout from the front right corner of the deck. Emptying the bags at this point will minimize the potential for the tube to plug.

6.4 If there is excessive blowout from the deck, check to make sure that the rear screen in the hood is clear of grass build up. It is recommended that the screen and mesh portions of the bags be cleaned regularly to maintain proper air flow. This is especially important in wet conditions.

6.5 During dry conditions check engine air cleaners and clean cooling fins more frequently. The Ultra Vac has been designed to minimize the impact of dust and debris on the mower, but bagging can be a dirty environment.

6.6 During dry conditions, switching to a lower lift blade may reduce blowout without hurting quality of cut.

6.7 Maintaining a ground speed that does not pull down the engine RPM will allow for the highest productivity and best quality of cut. Bogging the engine RPM down by going too fast will cause plugging and quality of cut issues.

6.8 When storing the Ultra Vac, it is recommended that any build up in the blower be cleaned out. Dry grass build up may cause problems with the impeller when the unit is put back into operation.

6.9 If the blower drive belt snaps or breaks frequently, check the alignment of the idler arm per section 5. An arm that is bent out of position can cause the belt to jump off of the idler and be cut by the sheaves.

6.10 If the idler pulley contacts the deck sheave, check the alignment of the idler arm per section 5. Also check the mounting tube on the deck and the mounting pin on the blower for bending or excessive wear. This condition is more likely to occur with smaller deck sizes.

This warranty is limited to one year from the date of original retail purchase (90 days for rental use) for any Exmark mower that is used for commercial or any other income producing purpose. The blade spindle assemblies will be warranted for three years, one year parts and labor with an additional two years parts only, from date of original retail purchase against defects in materials or workmanship. The frame and hydrostatic traction drive system, excluding hoses, will be warranted for two full years from date of original retail purchase against defects in materials or workmanship. We will extend the Peerless 5-speed transmission manufacturer's warranty from 90 days to one year. Belts and tires are warranted for 90 days against defects in materials or workmanship.

The warranty shall not extend to the expense of delivering the mower to the dealer for warranty work nor the expense of returning it back to the owner after repair or replacement. Our responsibility in respect to claims is limited to making the required repairs or replacements, and no claim of breach of warranty shall be cause for cancellation or rescission of the contract of sale of any Exmark mower. Proof of purchase may be required by the dealer to substantiate any warranty claim. All warranty work must be performed by an authorized Exmark service dealer.

This warranty extends only to turf equipment operated under normal conditions and properly serviced and maintained. The warranty expressly does not cover: (i) any damage or deterioration due to normal use, wear and tear, or exposure; (ii) normal maintenance services, such as oil change, cleaning, lubrication; adjustment; (iii) replacement of service items, such as oil, lubricants, spark plugs, or other items subject to normal service replacement; (iv) damage or defects arising out of or relating to misuse, neglect, alteration, negligence or accident; (v) repair or replacement arising from operation of or use of the turf equipment which is not in accordance with operating instructions as specified in the operator's manual or other operational instructions provided by Exmark; (vi) repair or replacement arising as a result of any operation from turf equipment that has been altered or modified so as to, in the determination of Exmark or Exmark Warranty Company, adversely affect the operation, performance or durability of the equipment or that has altered, modified or affected the turf equipment so as to change the intended use of the product; (vii) repair or replacement necessitated by use of parts, accessories or supplies, including gasoline, oil or lubricants, incompatible with the turf equipment or other than as recommended in the operator's manual or other operational instructions provided by Exmark; (viii) repairs or replacements resulting from parts or accessories which have adversely affected the operation, performance or durability of the turf equipment; or (ix) damage or defects due to or arising out of repair of turf equipment by person or persons other than an authorized Exmark service dealer or the installation of parts other than genuine Exmark or Exmark recommended parts. As a condition to this warranty, customer shall have read the operator's manual and shall have completed and returned to Exmark Warranty Company, within the prescribed time, the Exmark warranty registration.
