Safety Rules & Information

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mow- ing deck is capable of amputating hands and feet and throwing objects. The triangle in text signi- fies important cautions or warnings which must be followed.

GENERAL WARNINGS

● Know the tractor controls and how to stop quickly. READ THE TRACTOR OPERATOR’S MANUAL.

● Read and obey all safety decals.

● Only allow responsible adults, who are familiar with

the instructions, to operate the unit.

● Disengage the electric clutch (PTO). Shut off the engine and wait for all moving parts to stop before attaching, adjusting, or disconnecting any part of the collection system.

● Check the collection system to make sure it is bolted tightly to the tractor.

● DO NOT operate the mower without either the entire grass catcher or the deflector in place.

● Turn off the PTO switch to disengage the blades when not mowing.

● DO NOT mow in reverse. Always look down and behind before and while travelling in reverse.

● DO NOT turn sharply when travelling alongside a building or any object. Slow down before turning.

● DO NOT carry passengers on the tractor.

● When blower assembly is removed from the mower

deck, the deflector must be properly installed.

● If the mower stalls or the turbo blower chute plugs:

1. disengage the electric clutch (PTO);

2. stop the engine and remove the key;

3. set the parking brake, and wait for all moving parts to stop.

4. Remove the foreign object or clear the chute with a piece of wood before restarting the engine.

NEVER PLACE HANDS INTO BLOWER HOUSING TO CLEAR JAMMED OBJECT. BLOWER MAY ROTATE WHEN OBJECT IS REMOVED.

● For added tractor stability and to prevent tipping or loss of control:

a. Use reduced speed on uneven ground and when

turning corners.

b. Reduce loads on hillsides. It is recommended that

the collection system be kept only half full when negotiating any slopes. Start mowing on slopes when the collection system is empty.

c. Mow up and down the face of slopes; never

across the face of any slope.

● When operating on slopes, use front counterweights. On slopes over 15% (8.5°), use two rear wheel weights in addition to front counterweight. Never

operate on slopes greater than 30% (16.7°).

BEFORE OPERATION

Clear the lawn of all sticks, stones, wire and other debris which may be caught or thrown by the mower blades.

Check grass condition. If wet, wait until later in the day. If grass is wet, as the grass catcher is likely to become plugged.

For efficient grass collection, air circulation under the mower deck, through the chute and into the grass catcher or cart is very important.

For this reason, BEFORE YOU BEGIN MOWING you should make certain the underside of the mower and the underside of the catcher lid are free from grass and debris.

Make sure that there is a snug fit between mower deck, blower housing, tubes, and grass catcher cover.

MO WING WITH THE TURBO

Always operate with throttle at full speed when mowing. Grass should be cut often, and not too short. If grass is

too long or lush it may be necessary to keep ground speed to a minimum or to cut only half the width of the mower to prevent clogging. If grass is long, operate with mower in high cutting position for first pass, cutting again in a lower position on a second pass.

To check if grass is flowing up tube, view tube. Do not

open cover with mower engaged.

If a large amount of cut grass is spilling out from under deck, the tube may be plugged or the catcher may be full— discontinue mowing, stop the tractor, disengage the PTO and then empty the catcher or clear the tube.

OPERATING WITHOUT THE TURBO

If you need to mow without the turbo vacuum collector in place (for instance, if the grass is too wet to bag, but must be mowed)—you must remove the turbo blower from the mower deck, and properly position the deflector BEFORE you begin mowing.

General

Operating Instructions

WARNING

ALWAYS shut off the tractor. disengage the PTO, and allow all moving parts to stop BEFORE disconnecting or clearing tube, or emptying catcher.

Before leaving the operator’s position for any reason, engage the parking brake, disengage the PTO, stop the engine and remove the key.

To reduce fire hazard, keep the engine, tractor and mower free of grass, leaves and excess grease. Do not stop or park tractor over dry leaves, grass or combustible materials.

WARNING

To operate without the collection system, the blower assembly MUST be removed and the deflector MUST be in the down position.

The deflector is spring loaded. when removing the blower, hold the deflector up; then allow the deflector to go down into the normal operating position.

RECOMMENDED ACCESSORIES

When operating on slopes with a rear attachment, use front counterweights. If you will be operating on slopes over 15% (8.5°) two rear wheel weights are recommended in addition to the front counterweights. Never operate

on slopes greater than 30% (16.7°).

AFTER OPERATION

The turbo blower housing and tube should be removed for cleaning. Remove the tube by unlatching the lower tube rubber band from blower housing. When reattaching, make sure there is a snug fit between the mower deck, turbo blower housing, and grass catcher.

ATTACHING THE TURBO

1. Lift up the deflector.

2. Engage the stone guard hook at the bottom of the turbo as shown in Figure 8.

3. Slide turbo assembly as far rearward as possible so that the front turbo edge is tight against the front mower deck edge. Secure the turbo with the hair pin clip (B, Figure 7).

4. Move the idler release lever (C) to release belt tension.

5. Route the belt as shown in Figure 10. Make sure it is seated in all pulley grooves. The belt must be routed to the inside of the 2-1/4" capscrew as shown in Figure 10.

6. Close the belt cover (E. Figure 7) and tighten the knob into the pal nut.

7. Make sure that deflector rests on upstop (D, Figure 9) and does not contact the turbo housing. If deflector contacts housing, use washer(s) as shims under the upstop legs to increase clearance.

NOTE: After initial assembly, it is not necessary to remove mower deck when removing or installing turbo assembly.

REMOVING THE TURBO

NOTE: After initial assembly, it is not necessary to remove mower deck when removing or installing turbo assembly.

ADJUSTMENTS

Pulley Adjustments

If the mower deck belt has stretched over time, the stacked idler pulley (B, Figure 10) may need to be moved to the outer hole in the mower deck to take up the belt slack.

If the mower idler pulley (B) is mounted in the outer hole in the deck, then the turbo idler pulley (C) should be as far toward the front as the slot will allow. If the stacked idler pulley (B) is mounted in the inner hole, then the turbo idler pulley (C) should remain as installed at factory.

To adjust:

1. Loosen the back-side idler pulley (C, Figure 10) hardware.

2. Move the idler pulley forward in the adjustment slot and then re-tighten the hardware.

Upstop Adjustment

The upstop (E, Figure 9) prevents the deflector (F) from contacting the top of the turbo. If the upstop is not providing sufficient clearance, shim the upstop with washers until the deflector does not contact the turbo.

STORAGE

Remove any debris from the turbo blower housing. If you clean the housing, use a mild detergent only (other products may damage tube). If paint has been scratched on metal parts, touch up with paint, or apply a thin film of oil.

To prevent corrosion, store in a dry area, away from moisture.
