For the larger snow blowers I've worked on, there are 4 bolts (2 per side and by the drive wheels) which hold the front and rear assemblies together. You need to remove the top bolt on each side and loosen the bottom one to allow the two halves to split. Be careful not to damage your cables. Once split you may have to unbolt an idler pulley, remove a cable...
You should try an get a manual online to confirm.
