gun after every 25 hours of tractor operation
DeckSpindles
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.
