This document describes the installation and assembly of a Front Bumper Kit designed for FastAttach™ Compatible 600- and 800-Series Tractors, as well as Compatible 600- and 800-Series Box-Frame Tractors. The specific models covered are OEM-190-679 and 190-679-101. The manual, Form No. 769-00041C, was printed in the U.S.A. on January 25, 2006.

Function Description:

The Front Bumper Kit serves as an accessory to provide protection to the front end of compatible tractors. Its primary function is to absorb impacts and prevent damage to the tractor's grille, engine components, and other front-facing parts during operation, especially when navigating obstacles or in the event of minor collisions. The bumper enhances the durability and longevity of the tractor by safeguarding critical areas. It is designed to be easily mounted, allowing users to add this protective feature without extensive modifications. The kit is compatible with both FastAttach™ systems, which implies a quick and tool-less or minimal-tool attachment process for certain tractor types, and traditional box-frame tractors, which may require a more standard bolted installation.

Important Technical Specifications:

The kit includes several components necessary for installation:

Front Bumper: Part number (768-0010B). This is the main structural component that provides protection.
Two Clevis Pins: Part number (711-0332). These pins are used to secure the bumper to the tractor frame, particularly for FastAttach™ compatible models.
Two Cotter Pins: Part number (714-0145). These small pins are inserted through the clevis pins to prevent them from dislodging, ensuring a secure attachment.
Four Hex Bolts: Part number (710-1260A). These threaded fasteners are used for securing the bumper, especially for box-frame tractor installations.
Four Hex Flange Nuts: Part number (712-3004A). These nuts are designed to be used with the hex bolts, providing a secure and self-locking connection due to their integrated flange.

The compatibility extends to:

FastAttach™ Compatible 600- and 800-Series Tractors.
Compatible 600- and 800-Series Box-Frame Tractors.

Usage Features:

The installation process is detailed for different tractor types, highlighting the versatility of the kit:

For FastAttach™ Compatible Tractors:

Preparation: The tractor must be placed on a firm and level surface. The PTO (Power Take-Off) should be in the disengaged (OFF) position, the engine stopped, and the parking brake set. This ensures safety during installation.
Muffler Warning: A crucial safety note warns that the muffler may be hot and advises ensuring the engine has cooled down before installation to prevent burns.
Mounting: The bumper is mounted by hooking its notched ends (slots) onto the shoulder bolts located on the sides of the tractor frame. This suggests a quick, potentially tool-less initial attachment.
Securing: The holes in the bumper are then aligned with corresponding holes in the tractor frame. Clevis pins are inserted from the outside through these aligned holes, and cotter pins are used to secure the clevis pins in place. This method leverages the FastAttach™ system's design for rapid attachment and detachment.

For Box-Frame Lawn Tractors and Box-Frame Garden Tractors:

Preparation: Similar to FastAttach™ tractors, the tractor must be on a firm, level surface with the PTO disengaged, engine off, and parking brake set.
Muffler Warning: The same warning about a hot muffler is reiterated, emphasizing the need for the engine to cool down.
Mounting: The bumper is slid over the front brackets of the tractor. The two holes in the bumper are aligned with the two upper holes in the tractor's front bracket.
Securing: Hex bolts are inserted from the outside through these aligned holes. Hex flange nuts are then used to secure the bolts, providing a strong, bolted connection.
Muffler Guard Consideration: An important note specifies that if the tractor is equipped with a muffler guard between the tractor brackets, the hex bolts should be bolted directly into the guard. In this specific scenario, the hex flange nuts are not necessary, indicating that the muffler guard itself has threaded holes to accept the bolts, simplifying the attachment and potentially providing a more integrated fit.
Visual Aids: Figures 2 and 3 provide exploded views for clarity, illustrating how the front bracket, bumper, hex bolts, and hex flange nuts interact during assembly for box-frame tractors. Figure 1 visually depicts the shoulder bolt, slot, clevis pin, and cotter pin for FastAttach™ compatible tractors.

Maintenance Features:

While the manual primarily focuses on installation, some aspects imply maintenance considerations:

Secure Fasteners: The use of cotter pins with clevis pins and hex flange nuts with hex bolts suggests a design aimed at preventing loosening due to vibration during tractor operation. Regular checks of these fasteners would be a good maintenance practice to ensure the bumper remains securely attached.
Durability: The bumper itself, being a protective component, is designed to withstand impacts. Its material and construction are intended for durability, reducing the need for frequent replacement unless subjected to severe damage.
Ease of Removal: The FastAttach™ system, by its nature, allows for relatively easy removal of the bumper if access to the front of the tractor is needed for other maintenance tasks or if the bumper is not required for a specific operation. The bolted connections on box-frame tractors, while more involved than FastAttach™, are still standard and allow for removal with basic tools.

Customer Support:

The manual provides clear instructions for seeking assistance:

Contact Information: Users can call 1- (330) 220-4MTD (4683) or 1- (800)-800-7310 for customer support regarding assembly, controls, operation, or maintenance.
Required Information: When calling, users are advised to have their unit's model number and serial number ready. This information is crucial for the customer support representative to accurately identify the product and provide relevant assistance. The manual directs users to a "previous section" (not included in the provided excerpt) to locate this information, indicating a comprehensive manual structure. The serial number is specifically mentioned as being required for processing the call, highlighting its importance for tracking and support.

Overall, the Front Bumper Kit is presented as a straightforward, protective accessory with clear installation guidelines tailored to different tractor designs, emphasizing safety and ease of use.
