Link Position

To Avoid Personal Injury:

• Become familiar with all operating and

safety instructions in the operator’s manual for your tractor and mower before using this attachment.

•

Never r

emove the discharge tube, bags, bagger top, or the blower while the engine is running.

• Always shut the engine off before clearing

an obstruction from the vac bagging system.

• Never do maintenance or repairs while the

engine is running.

Adjusting

When mower height-of-cut is changed, the spring location in the chain links must also be changed.

1. Select spring attachment link according to chart

for the height-of-cut used.

ester

As grass is cut and blown into the bags, the left bag fills first, then the right bag. If you overfill the bags, grass will eventually plug the discharge tube or elbow.

1. Stop the tractor and apply the brake.

2. To check if both bags are full, periodically raise

the full bag tester handle (Fig. 41). If you feel resistance as you raise the handle, the bags must be emptied because they are full (Fig. 41).

2. Hook spring into recommended link (Fig. 40).

Operation

Emptying

Grass bags can weigh up to 90 lb (41kg) when full. Be careful when lifting or handling a grass bag that is full. To empty the grass bags:

1. Stop the tractor, set the parking brake, and

disengage the power take off (PTO) by pulling the PTO control to OFF (this stops the mower blades). Shut the engine off before you get off the tractor. Remove the ignition key.

2. Tip the tractor seat forward.

3. Pull up on both bag retainer handles until they

unlock from the bag frame (Fig. 26). Now open (raise) the bagger top.

4. Compress debris into the bags. With both hands,

lift up on the bag and unhook it from the retaining bracket (Fig. 25). Empty the bag. Repeat for the other bag.

4. After you remove the obstruction, install the

complete bagger system and resume operation.

Operating

Size

Remember that the tractor is longer and wider with this attachment installed. By turning too sharply in confined places you may damage the attachment.

Trimming

Always trim with the left side of the mower. Do not trim with the right side of the mower because you could damage the bagger’s blower and discharge tube.

Cutting Height

Do not set the mower cutting height too low because long grass surrounding the mower can prevent air from getting under the mower and entering the bagging system. If enough air doesn’t get under the mower, the bagging system will plug.

and Bagging T

ips

5. Install the bags by attaching the bag frame hooks

onto the retaining brackets (Fig. 25).

6. Lower the bagger top onto the bags. Then push

down on both bag retainer handles until they lock on the bag frame (Fig. 26).

7. Move the tractor seat to its normal position.

Clearing

Obstructions

From Bagger

1. Stop the tractor, shift into neutral, set the parking

brake, pull the PTO control to OFF (this stops the mower blades), turn the ignition key to OFF to stop the engine, and remove the key from the switch.

2. Check the grass bags and empty them if they are

full.

3. Remove and separate the discharge tube and

blower from the bagger top and mower. Using a stick or similar object, carefully remove and clear the obstruction from the mower, discharge tube, blower, and the bagger top.

Cutting Frequency

Cut the grass often, especially when it grows rapidly. You will have to cut your grass twice if it gets excessively long (refer to Bagging Long Grass, page 23).

Cutting Technique

For best lawn appearance, be sure to slightly overlap the mower into the previously cut area. This helps reduce the load on the engine and reduces the chance of plugging the blower andischarge tube.

Page 25

Using Bags

Although not required, bags may be inserted into each cloth grass bag as a liner to collect clippings and make disposal more convenient (Fig. 42). If you use a bag liner, remove the filled grass bag and close the top of the liner. Then pull the liner out the grass bag or turn the bag upside down while holding the handle on the bottom of the grass bag (allows liner to slide out).

Operation

POTENTIAL HAZARD

• As the grass bags fill, extra weight is added

to the back of the tractor.

WHAT CAN HAPPEN

• If you stop and start suddenly on hills, you

may lose steering control or the tractor may tip.

HOW TO AV

OID THE HAZARD

• Do not start or stop suddenly when going

uphill or downhill. Avoid uphill starts.

• If you do stop the tractor when going

uphill, disengage the PTO (stop the mower blades) by pushing the PTO control to OFF. Then back down the hill using slow r

everse speed.

• Do not change speeds or stop on slopes.

Bagging Speed

Most often you will bag with the tractor throttle in the FAST position and drive at a normal ground speed. However, in extremely dry and dusty grass, you may want to slightly reduce throttle speed and increase ground speed of the tractor. The bagging system may plug if you drive too fast and the engine speed gets too slow. On hills it may be necessary to slow the tractor’s ground speed. This helps maintain engine speed and bagging efficiency. Mow down hill whenever possible.

Bagging Long Grass

Excessively long grass is heavy and may not be propelled completely into the grass bags. If this happens, the discharge tube and blower may plug. To avoid plugging the bagging system, mow the grass at a high height-of-cut, then lower the mower to your normal cutting height and repeat the bagging process.

Bagging W

et Grass

Always try to cut grass when it is dry because your lawn will have a neat appearance. If you must cut wet grass, use the conventional side discharge feature of the mower. Several hours later, when the clippings are dry, install the complete bagger attachment and vacuum up the grass clippings.

Signs of Plugging

As you are bagging, a small amount of grass clippings normally blow out the front of the mower. An excessive amount of clipping blow-out indicates that the bags are full or the system is plugged.
