5 year old -48'' cut cub cadet riding lawn mower. 18 horse briggs engine. When mower was a couple of years old, engine started dragging when you tried to start. It would always start. Kept getting worse, Changed out battery-no change, changed starter, no help, cleaned ground connection, no help.In the past, after it started and you drove it a while, turned off-then restarted-it would start with out dragging.Yesterday it would not start -even after putting a 125 amp. charger to battery.Any suggestions? Starter solinoid maybe?
It may be a problem with the camshaft-compression release. Some of the Briggs & Stratton models had a weak spring on the compression release whis is parts of the camshaft. you may also want tocheck that all wires are clean and tight. Also if it's a over head valve model check the valve clearance.

You will need to remove the left fender/tank to access the throttle lever mounting screws. Make either written notes or take snap shots as you remove the old cable as there are several different setups for this mower series so you can install the new cable correctly.
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.
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.
What have you changed?? What model lawn mower is it? Is it a riding lawn mower or a push lawn mower? Does it turn over(engine turning with the starter), or does it do nothing when you turn the key over? I have serviced cub cadets for almost 20 years, from the very first model(1959) to present, and i own 13 different tractors myself. if anyone can help you, i should be able too. i just need more info about the unit and its problems. i look forward to helping you.... -Brian-
remove the starter...use jumper cables to "run the starter manually...red to big lug, black to body (anywhere is fine) should torque hard at initial run and continue to run smooth...if it buzzes or vibrates, it's bad...replace...
