Lubrication

WARNING: Before lubricating, repairing, or inspecting, always disengage PTO, set parking brake, stop engine and remove key to prevent unintended starting.

Engine

Refer to Engine on page 19 for instruction regarding all engine-related lubrication.

Front Wheels

Each of the front wheel axles and rims is equipped with a grease fitting. See Figure 16. Lubricate with a No. 2 multi-purpose grease applied with a grease gun after every 25 hours of tractor operation.

Pivot Points & Linkage

Lubricate all the pivot points on the drive system, parking brake and lift linkage at least once a season with light oil.

Deck Wheels

Each of the tractor deck’s front gauge wheels is equipped with a grease fitting. Lubricate with a No. 2 multi-purpose grease applied with a grease gun after every 25 hours of tractor operation

Deck Spindles

Grease fittings can be found on the front of each deck spindle shaft. Lubricate with 251H EP grease or an equivalent No. 2 multi-purpose lithium grease. Using a grease gun, apply two strokes (minimum) or sufficient grease to the spindle shaft.

Carburetor

NOTE: Carburetor adjustments should be made only after the engine has warmed up.

The engines on Cub Cadet Series 1500 tractors are equipped with a fixed main jet carburetor.

Carburetors are equipped with a idle speed adjustment screw and a low idle fuel mixture screw.

The Fuel Mixture Screw is the uppermost screw.

The Idle Speed Adjustment Screw is the lower screw.

The carburetor is designed to deliver the correct fuel-to- air mixture to the engine under all operating conditions. The main fuel jet is calibrated at the factory and is not adjustable. The low idle fuel mixture screw is also set at the factory and normally does not need adjustment.

If the engine is hard to start, runs roughly, or stalls at low idle speed, it may be necessary to adjust or service the carburetor.

Turning the low idle mixture screw in (clockwise) decreases the supply of fuel to the carburetor. This gives a leaner fuel-to-air mixture. Turning the mixture screw out (counterclockwise) increases the supply of fuel to the carburetor. This gives a richer fuel-to-air mixture. Setting the screw midway between the lean and rich position will usually give the best results.

Troubleshooting

If engine troubles are experienced that appear to be fuel system related, check the following areas before adjusting the carburetor.

Make sure the fuel tank is filled with clean, fresh gasoline.

Make sure the fuel tank cap vent is not blocked and that it is operating properly.

If the fuel tank is equipped with a shut-off valve, make sure it is open.

Make sure that the in-line fuel filter is clean and unobstructed. Replace the filter if necessary.

Make sure fuel is reaching the carburetor. Check the fuel lines and fuel pump for restrictions or faulty components, replace as necessary.

Make sure the air cleaner element is clean and all

air cleaner element components are secure.

If, after checking the items listed above, the engine is hard to start, runs roughly, or stalls at low idle speed, it may be necessary to adjust or service the carburetor.

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.
