Hi aussietrev, it is a model 28269 built in about 2007, my problem is not a loose belt but in fact the opposite, it will not dis engage the belt I need to loosen something some where so that when I dis engage the deck it will stop spinning and not be to tight that the motor is still not running free, there must be some nut some where to back off and let the motor run free when the deck is dis engaged.
Regards
Nick
