just order a belt for a 95 Buick le Sabre without ac.
Question is too vague as ther are more than one size deck.
what size is the belt for a 46 in cut deck belt with 6 pulley's.
43
Most LT12H mowers take a #213676 OEM belt or #6885 Gates belt for the blade application
Hard to answer without a deck size.
a115 for triple deck
Gates
5/8 x 57"
somewhere in the 44" size but best to look on the belt for a number or remove it and match it to a new belt. might also measure around around the pulleys with a small rope/string if you don't have a old belt to get the size of the belt.
the drive belt is 76 length 1.5 width
No the drive belt and Deck belt are two different belts, one powers the rear wheels, the other powers the deck. though if you are asking if they are the same belt as in same size, I don't know, you'll have to check your owners manual or talk to someone who repairs or can get parts for Cub Cadet mowers.
