Note: The diagram may not be exactly the same as your specific model of John Deere 175 tractor, but it should provide a general idea of the belt routing.
Snow Blower Drive Belt:
1. Starting at the top, the drive belt winds around the idler pulley.
2. From there, it winds around the snowblower drive pulley.
3. The belt then moves down and around the engine idler pulley.
4. The drive belt then wraps around the engine crankshaft pulley.
Snow Thrower Fan Belt:
1. Moving toward the front of the tractor, a separate fan belt winds around the engine crankshaft pulley.
2. From there, it wraps around the snow thrower fan pulley.
Auger Drive Belt:
1. If your John Deere 175 tractor has a power take-off (PTO) driven snowblower, there will also be a third belt called the auger drive belt.
2. This belt routes from the PTO shaft pulley to the auger drive pulley on the snowblower.
