Attachments Cub Cadet LTX-1146 Lawn Tractor/ MTD-OEM-190-627 Blower

Hello everyone, I just purchased a MTD-OEM-190-627 snow blower attachment for my CubCadet LTX1146 rider.It was taken off the same model as mine & modified to fit the cub cadet.I brought it home & attached it to my machine finding out that my drive belt pulley sits around 2 in higher than the blower belt pulley.My question is are all the cubcadet LTX 1146 machines identical? Before I go any farther I though I should find this out just in case they used different length pully shafts or whatever. Hope someone has an answer.Thanks- Kroochman
