INGS WHICH MUST BE FOLLOWED.

WARNING

???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, disengage the electric clutch (PTO), stop the engine and remove the key. set the parking brake. wait for moving parts to stop. 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 counterweight. Never operate on slopes greater than 17.6% (10??).

???Know the tractor controls and how to stop quickly.

READ THE TRACTOR OPERATOR???S MANUAL.

???Disengage the electric clutch (PTO). Shut off the engine, remove the key, 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.

???Look behind to make sure the area is clear before backing up.

???DO NOT turn sharply when travelling alongside a building or any object.

???DO NOT carry passengers on the tractor.

???Read and obey all warning decals.

OPERATION

WARNING

Read and obey all operation and warning decals.

WARNING

??? Do not open cover with engine running.

??? Do not operate mower without the complete catcher in place

???When operating on slopes, refer to operator's manual for counterweights.

Operation With Turbo

???Grass should be cut often but 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 to prevent clogging. If grass is too high, operate with mower in high cutting position. Cut the grass again in lower cutting position, if desired.

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

???The blower housing should be removed for cleaning. If a large amount of cut grass is spilling out from under the deck, the tube may be plugged or grass bags are full. Shut off tractor, disengage the PTO, remove the key, and allow all moving parts to stop before disconnecting the tube.

???Always operate at full throttle speed.

Operation Without Turbo

???For operation without the turbo, the deflector must be properly installed in the down position and retained by the spring latch.

???To remove turbo, reverse the installation steps.

Recommended Accessories

???Front counterweight is recommended when using rear-mounted grass catcher.

???On slopes over 17.6% (10??), use two rear wheel

weights in addition to front counterweight.

Always mow up and down the face of slopes, never across the face. Never mow on slopes greater than 30% (16.7 degrees)

NOTE: The following procedure can be performed with the mower installed on the tractor, however for ease of installation, removing the mower deck is recommended

Install Hook Plate

1.Remove the right side belt cover and retain taptite screws.

2.Remove the deflector, spring, and hinge assemble. Retain the hardware except for the carriage bolts. Use a hammer to drive the carriage bolts back through the deck, and discard the bolts.

3.Install the hook plate (B, Figure 1) below the stone guard using two 5/16-18 x 3/4 carriage bolts (A) and flange locknuts (D). Install the bolts from the bottom up.

Install Pulley

1.Remove the right arbor capscrew, lockwasher, and washer. Discard the capscrew; retain the lockwasher and washer.

2.Install the pulley and hub assembly (D) on top of the original pulley. Secure with a new 7/16-15 x 2-1/4 capscrew (A) and original lockwasher (B) and washer
