Small Engines (Lawn Mowers, etc.): belt routing for troy bilt LX1842, variable speed pulley, troy bilt

Question
the main drive belt shredded from the motor pulley on back how do i route the new belt back on THANKYOU in advance ,for your help

Answer
I will try to explain this, although it may be difficult. First all explanations will be considered from laying under the mower with your head toward the front. The right side goes from the rear variable speed pulley straight to the pto pulley goes around and comes back to the double idlers. It goes with the backside of the belt around the first pulley, then the front side around the other to the variable speed pulley(like a backward s)
