Changing the Deck Belt(s)

WARNING: Shut tractor engine off, remove ignition key, disconnect the spark plug wire(s) and ground against the engine before proceeding with job.

IMPORTANT: The V-belts on your tractor are specially designed to engage and disengage safely. A substitute (non- OEM) V-belt can be dangerous by not disengaging completely. For a proper working machine, use factory approved belts.

•All belts on the tractor are subject to wear and should be replaced if cracking, shredding or rotting occurs. To change or replace the deck belts on your tractor, proceed as follows:

1.Lower the deck by moving the deck lift lever to the lowest position.

2.Take the belt guards off by removing the self-tapping screws that fasten them to the deck surface. See Figure 18 & Figure 19 (as the case may be) for location of the screws.

3.Grasp the PTO idler bracket and pivot it toward the discharge chute to relieve tension on the PTO belt.

The engine's design emphasizes fuel efficiency, which allows users to cover more ground while minimizing fuel consumption.

Another significant characteristic of the MTD 604H is its innovative cutting deck. The mower features a wide cutting deck that can range from 36 to 42 inches, allowing for a larger clipping area.

Safety is a crucial aspect of the MTD 604H. The mower is equipped with automatic blade brakes that stop the blades almost instantly when the user releases the control lever. This feature significantly reduces the risk of accidents and enhances user safety while operating the machine.

In conclusion, the MTD 604H is a feature-packed lawn mower characterized by its powerful engine, wide cutting deck, user-friendly technologies, and safety features.
