I bought a new belt for my2005 lt 1000 42" deck

Any debris on top of the deck e.g. thumb sized mulch, driveway stones, pencil diameter sticks or larger. All may cut and snap a belt if they get wedged between the belt and any of the pulleys.

Any hard foreign object of the size that will jamb into a pulley v groove.

Do the engine rpms drop or only the blade speed?

If belt is tight at cutting height and engine rpms hold, then the vbelt from engine to deck is likely is dry burnished or oily.

First check the blades are install cutting edge down (fin up). If belt from engine to deck has a glassy finish (burnished) replace belt or remove burnish with sandpaper.

It appears be relatively complicated deck system. See owners manual regarding deck remove/install.

check belt and pulleys --if belt to loose wont turn blades to cut the grass

Do the blades need sharpening? Check the belts for tightness and the spring that holds the tension. what stops? The blades stop, but the belt is still turning? Check to also make sure the blades turn freely with the belt disengaged. you may have a spindle problem too.

it's usually on top of the deck clean off the grass and look on top may have to remove it to see

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.

just bought a new craftsman riding mower. model lt1500. 17.5 hp with 42 inch deck. first time using I had the deck hight handle set on 6 the highest setting and still cuts grass to short, matter of fact it scalped the grass. anyway to set the deck higher. Its only 3 days old and still under warranty but the sears store is 20 miles away and I rented a trailer to go pick it up and hate to go rent another trailer to bring it back if its just a simple adjustment.

what is happening tom is the blades are cutting more than the deck can discharge (spit out) try changing the mowing deck to a higher setting & try that if that works then that is the problem also try cleaning out the top & botton of deck there could be alot of old grass caught under there causing some of it aslo if i can further help e-mail me wade at [email protected]

If the belt is loose it probably needs replaced or has jumped out of one of the pulley or belt guards allowing it to be sloppy. Belts get stretched in many different ways, tall grass, grass getting in the pulley, or they just plain stretch. First though, check to be sure the belt hasn't jumped out of it's normal runway.

It sounds to me like a very loose belt or very worn out belt and also an adjustment problem.
