Cub Cadet SLT1550, SLT1554, SLT1554, SLT1550 Hydrostatic Transmission, Changing the Deck Belt

Page 27

Hydrostatic Transmission

Keep the area around the transmission cooling fan free of grass and debris at all times. The hydrostatic transmission is sealed at the factory and is maintenance free. The fluid level cannot be checked and on most models, cannot be changed.

IMPORTANT:Several tractor components and parts (pedals, seat, fender, fuel tank, etc.) must be removed in order to refill the transmission after draining it.

If your tractor is equipped with a transmission drain plug (see Figure 20), exposed to extreme conditions (hilly terrain, towing, etc.) and you choose to change the hydrostatic fluid, do so after the tractor’s initial 50 hours of operation and every 100 hours of operation thereafter.

Drain Plug

NOTE: View shown from beneath tractor.

Figure 20

After draining the oil, refill the transmission with 76 oz. (to the top of the fill hole found on the transmission’s surface) with any SAE 20W 50 motor oil.

Changing the Deck Belt

WARNING: Be sure to shut the engine off, remove ignition key, disconnect the spark plug wire(s) and ground against the engine to prevent unintended starting before removing the belt(s).

WARNING: Avoid the possibility of a pinching injury. Do not place your fingers on the idler spring or between the belt and a pulley while removing the belt.

All belts on your tractor are subject to wear and should be replaced if any signs of wear are present.

IMPORTANT:The V-belts found 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.

To change or replace the deck belt on your tractor, proceed as follows:

•Lower the deck by moving the deck lift lever into the bottom notch on the right fender.

•Remove the belt guards by removing the self- tapping screws that fasten them to the deck.

•To ease in removing the belt in later steps, loosen, but do not remove, the bolt which secures the pivoting idler pulley to the idler bracket.

See Figure 21.

SLT1550, SLT1554, SLT1554, SLT1550 specifications

The Cub Cadet SLT1550 and SLT1554 are two impressive lawn tractors known for their powerful performance, innovative technologies, and robust design. Both models are tailored for homeowners who demand efficiency and reliability in maintaining their yards.

The SLT1550 is equipped with a reliable 50-inch cutting deck, while the SLT1554 features a slightly larger 54-inch deck, providing greater coverage for larger lawns. These cutting decks are designed for an even and clean cut, enhancing the overall appearance of your lawn. The decks are also constructed with durable materials that ensure long-lasting performance, resisting wear and tear even under heavy use.

One of the standout features of both models is the powerful engine. The SLT1550 is powered by a reliable Kohler engine, offering 23 horsepower, while the SLT1554 is equipped with a similar-grade engine. This powerful drive enables both tractors to tackle tough terrain and thick grass with ease, significantly reducing mowing time and effort.

Another significant aspect of these lawn tractors is their Hydrostatic transmission. This technology allows for smooth, automatic shifting without the need for manual gear changes, providing an intuitive driving experience. Users can easily adjust their speed while maintaining control over the tractor, making it ideal for both novice and experienced users.

Comfort and ergonomics are key considerations in the design of the SLT1550 and SLT1554. Both models feature an adjustable high-back seat, ensuring that operators can find the optimal position for their comfort during extended mowing periods. Additionally, the tractors are equipped with a user-friendly dashboard that includes essential indicators such as fuel level and engine temperature, allowing for easy monitoring while mowing.

For versatility, both models support various attachments, such as baggers, mulchers, and snow removal equipment, making them suitable for year-round use. The ability to adapt the tractor for different seasons adds significant value for homeowners who want a multi-functional machine.

Safety is also a priority, as both models come with essential safety features, including a terrain-gripping tire design, which enhances stability during operation on uneven surfaces. The tractors also incorporate a seat switch that ensures the engine shuts off if the operator leaves the seat while the mower is engaged.

In summary, the Cub Cadet SLT1550 and SLT1554 deliver a harmonious blend of power, comfort, and versatility, making them excellent choices for homeowners looking to maintain their lawns with ease and efficiency.
