This document is an Operator's Manual for a 50-inch and 54-inch Bagger designed for Zero-Turn-Radius Riding Mowers. It covers models 79392 (Serial No. 316000001 and Up, and 400000000 and Up) and 79416 (Serial No. 400000000 and Up). The manual provides comprehensive instructions for the installation, operation, and maintenance of the bagger attachment.

Function Description

The bagger attachment is designed to collect grass clippings and other debris while operating a zero-turn-radius riding mower. It enhances the cleanliness of the lawn by preventing cut grass from being left on the surface. The system includes a chute to direct clippings from the mower deck, a discharge tube, and grass bags for collection. The attachment also incorporates front weights to maintain machine stability, which is crucial given the altered weight distribution when the bagger is installed and filled. A draw bar feature on the bagger support bracket allows for towing light loads, though specific precautions are advised.

Important Technical Specifications

The manual does not explicitly list detailed technical specifications such as dimensions, weight capacity, or material composition of the bagger components. However, it provides part lists for various installation steps, indicating the types and sizes of fasteners used:

• Fasteners for Weight Installation: Bolt (3/8 x 1-1/4 inches), Locknut (3/8 inch), Bolt (3/8 x 1 inch).
• Fasteners for Attachment Mount Installation: Carriage bolt (5/16 x 3/4 inch), Locknut (5/16 inch), Self-tapping screw (5/16 x 3/4 inch), Bolt (5/16 x 1 inch).
• Fasteners for Bagger Top Installation: Bolt (5/16 x 1 inch), Nut (5/16 inch).
• Torque Specification for Cutoff Baffle: 7-9 N·m (14-18 ft-lb).

The bagger is compatible with 50-inch and 54-inch mower decks, with specific instructions for blowout baffle installation on 54-inch decks. The system uses two grass bags for collection.

Usage Features

The manual details several key usage features and operational guidelines:

Installation

The installation process is broken down into nine distinct procedures:

1. Installing the Weight: Crucial for maintaining machine stability, especially for models with control levers. It involves attaching left and right weight-mounting brackets, a flat weight, a suitcase weight, and a keyed cross bar to the underside of the frame.
2. Installing the Attachment Mount: Securing the stabilizer bracket and pivot frame to the machine frame using various bolts, locknuts, and self-tapping screws. Rods are then installed into the attachment mount.
3. Assembling the Bagger Top: Installing the bagger screen into the bagger top, ensuring it slopes down towards the collection bags.
4. Installing the Latch Rod: Securing the latch rod with a hairpin cotter.
5. Installing the Bagger Top: Attaching the assembled bagger top to the bagger frame and pivot brackets, then installing the grass bags by sliding their frames onto retaining brackets.
6. Installing the Cutoff Baffle: Attaching the cutoff baffle to the mower deck with bolts and locknuts, torqued to 7-9 N·m (14-18 ft-lb). (Note: Some models may have this pre-installed).
7. Installing the Blowout Baffle: (For 54-inch mower decks only) Securing the blowout baffle to the mower deck with carriage bolts and locknuts.
8. Installing the Chute: Angling the metal tab of the chute into a slot on the mower deck bracket, pivoting it flush with the deck, engaging a hook-shaped latch around the deflector assembly's pivot rod, and securing it with a flexible latch to a retaining clasp.
9. Connecting with the Discharge Tube: Sliding the curved end of the discharge tube into the bagger top opening and the flared end over the chute, then securing it with a rubber retaining strap.

Operation

• Emptying the Grass Bags: Involves parking on a level surface, disengaging blade control, moving motion control levers to NEUTRAL LOCK, shutting off the engine, removing the key, engaging the parking brake, and waiting for all moving parts to stop. The bagger top is then opened, debris compressed, and bags unhooked and emptied.
• Clearing Obstructions: Similar safety precautions as emptying bags. Requires separating and removing the discharge tube and chute, then carefully clearing obstructions from the mower deck, discharge tube, chute, and bagger top using a stick or similar object.
• Using the Draw Bar: The bagger support bracket includes a draw bar for towing. Users are advised to read all operating instructions, slow down and observe clearance when turning, make wide turns, and avoid excessive draw bar pull to prevent hydrostatic transmission failure.
• Operating Tips:
  • Remembering the Size: The machine is longer and wider with the bagger; avoid sharp turns in confined spaces.
  • Trimming: Trim with the left side of the machine to avoid damaging the bagger chute and discharge tube.
  • Cutting Height: Do not set too low; sufficient airflow is needed for effective bagging.
  • Cutting Frequency: Cut grass often, especially when rapidly growing, to prevent excessive length.
  • Cutting Technique: Slightly overlap previously cut areas to reduce engine load and prevent plugging.
  • Bagging Speed: Operate with throttle in FAST position and normal ground speed. Adjust speed in dry/dusty grass or on hills to maintain engine speed and bagging efficiency.
  • Bagging Long Grass: Mow at a high height first, then lower to normal cutting height and repeat to avoid plugging.
  • Bagging Wet Grass: Avoid bagging wet grass; use side discharge, then collect dry clippings later.
  • Signs of Plugging: Excessive clippings blowing out the front of the mower deck indicates full bags or a plugged system.

Maintenance Features

The manual outlines a recommended maintenance schedule and specific procedures:

Recommended Maintenance Schedule

• After the first 10 hours: Inspect the bagger.
• Before each use or daily: Clean the bagger.
• Before storage: Inspect the bagger, Clean the bagger.

Inspecting the Bagger Attachment

• Service Interval: After the first 10 hours and before storage.
• Procedure:
  1. Check the chute, discharge tube, and bagger top for cracks or breaks; replace if damaged.
  2. Tighten all nuts, bolts, and screws.
  3. Inspect all fasteners and latches; replace any missing or damaged.
  4. Inspect grass bags for deterioration (holes, rips, wear).
• Safety Warning: Emphasizes the risk of serious injury from flying debris if grass bags are torn or deteriorated. Advises against washing grass bags and to install new bags supplied by the manufacturer if deteriorated.

Inspecting the Mower Blades

• Inspect regularly and after striking foreign objects. Replace badly worn or damaged blades. Refer to the mower's Operator's Manual for detailed blade maintenance.

Caring for the Grass Bags

• Do not wash the grass bags.
• Store bags in a dry place after each use to prevent rapid deterioration.

Cleaning the Bagger Attachment
