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 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 1000 tractors are equipped with a Walbro fixed main jet carburetor.

Walbro carburetors have a low idle speed screw and a low idle fuel adjusting needle.

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