I have a cub cadet push mower with a 173cc ohv engine. i was cutting grass the other day and fire came out of the muffler and now it acts like its not firing maybe like it jumed time but not sure. thanks for any help in advance

be sure the battery is fully charged. be sure the blades are sharp. be sure there is no grass or string or wire wrapped around the spindles under the deck. be sure it is firing on both cylinders . be sure the belt is in good shape .

it is either the belt or cable. Remove the belt housing and see if the belt is in place and in one piece. move the propel lever back and forth with the motor off and see if the opposite end is moving like it should at that connection.

bade lift mower blade rteplace it

its runnig out of gas check fuel filter for being dirty replace it with new one

Check the oil, air filter, and run some non ethanol gas in it

check the clutch on the end of engine drive shaft it is the same as a car air con clutch put power on to it and it should click so most likely the wire from switch to clutch

Cub Cadet has five models in their new Series 1000 lawn tractors, all powered by Kohler engines. Cub Cadet models -- as several other lawn equipment brands -- are manufactured by MTD Products.

The Cub Cadet LT 1045 has a 20-hp Kohler single-cylinder engine, with an aluminum block and cast-iron sleeve for longer life. It has a full-pressure lubrication system with spin-on oil filter for easier maintenance. This engine is not as powerful or as long lasting as the Kohler V-Twin OHV, which is available in other models in the line, but the LT 1045's engine is still solid enough to provide years of mowing.

The hydrostatic (automatic) transmission is a good match with the engine and provides sufficient grip to cut grass on moderate inclines. Power is transferred from the engine to the transmission by a heavy-duty Kevlar belt rather than a more expensive shaft drive. A Kevlar belt also drives the three cutting blades.

The mowing deck cuts a swath of grass 46 inches wide at one pass, and is removable for service and cleaning. Four anti-scalping wheels help keep the deck from scalping grass on uneven ground. The cutting height is manually adjusted from 1-1/2 to 4 inches. The turning radius is 18 inches, which standard for lawn tractors. This model is intended for use on 1- to 2-acre lawns without many turns or small obstacles.

Is it the pull rope that broke?

Change the spark plug and the air filter. Also be sure the gas is new. If the gas has been in the mower all winter drain it out and put in fresh gas.

hello
check mower deck is not caked up with grass if it is it will not get enough air movementto force the grass up the chute
also try cutting in 2or3 passes so that you are not forcing too mush grass up the chute
hope this helps
