James W :

Also, it is important to always try to determine exactly why a belt has worn out, broken, or come off

James W :

90% of the time, the belts never have a chance to wear out and die a natural death on these units

James W :

In fact, the Cub cadets like this are known for having such problems repeatedly.

James W :

It would not be totally acurate to call this a "Design flaw".


Cub cadet WAS a quality brand of equipment before MTD bought them out


and MTD, to their credit, continued that great quality for about 5 years.


But that has been 20+ years.


Bolens, Troy-bilt, Yardman, Yard-power, White Outdoor, are all Formerly quality brand names that were not able to compete with the cheap mowers made by Murray, AMF, Roper, and MTD


So all of those brands went out of business


So then the NAMES Bolens, Troy-bilt, Yardman, Yard-power, White Outdoor, and of course Cub Cadet were purchased by MTD


MTD is now putting those Names on their cheaply made equipment


The public is being deceived into thinking they are buying quality merchandise just because of the name


You can read more of this on Wikipedia http://en.wikipedia.org/wiki/Cub_Cadet


So back to the problem at hand


The Problem is poorly designed equipment overall made of average quality materials


the belt guards will slip


the angles of the belt path are sharper than they should be


The mower will work better if adjusted to a Higher cutting height


ALSO, you cannot WASH this unit at all with water


The bearings are sealed against dirt, but they are not sealed against water


so the water will actually be sucked into the bearings (especially if warm) and mix with the grease


this will cause the bearings to wear much prematurely


If the bearings in the pulleys fail at all, then the pulley will slip against the belt and cause belt wear but also will throw the belt off if it freezes when it heats up


So check all the pulleys to make sure that they spin without ANY noise at all or vibrations


A good bearing in a pulley will spin smoothly and make no noise and you will not even feel it spin much


If the belt ever comes off, you cannot reuse it


it must be replaced on one of these


The back of the belt usually gets damaged and it will not stay on afterwards


ALSO


The deck design is not good


the way it is hung combined with the subpar quality in the materials make it susceptible to warping or bending in the middle


if the deck bends, then the pulleys will never line up perfectly


You cannot bend the deck back because it will weaken the deck further and it will bend even more easily


Also, the materials and design around the spindles on the deck is not good and if you hit anything with a blade, the deck will bend and the spindle will now set at an angle


This misalignment of the pulleys will again cause belts to jump


Look hard at the belt path. The belt cannot twist then twist back and stay on


The belt or a pulley cannot touch anything at all period


Look for a spring that may have come off or has weakened


and may not be applying enough tension

James W :

The same info applies to both the drive belts and mower belts... You can save yourslef a bit of money by doing a tiny bit of examination and research before just slapping a new belt on
