414-8 Belt Rubs Muffler

[WheelHorseVH 110]

Hi all, my brother in law just got a 2 stage WH snowblower that I installed on his 414-8. I know it is going to use all 14 of those horses to run it but he really wanted it. The biggest problem that I see right now is that when you lift it up to just the minimal lift, the belt touches the muffler on the K321 engine. 
 

Anyone run into this or have suggestions? Thank you.

Please post a pic of your set up on that side. Maybe we can figure out what's going on or what can be done to solve it

Guessing your muffler isn't installed horizontal

Be sure to get a real tachometer and check the actual RPMs. You'll want the snowblower going FULL speed.

 Actually, 2 pictures. One with it lowered for use, the other with it raised.

My guess is either improper belt routing, or as @wallfish mentioned, the position of the muffler.

Lowered, raised, and belt routing pics below. Thanks, gents. Insights are appreciated.

Yup, muffler needs to move if you want to run that blower. 

Run the engine until it's hot then try to remove those exhaust bolts holding it on. Maybe a threaded pipe 45 street fitting and a nipple. But you'll have to check the ID of the muffler pipe too. The engine should have threads for 1" pipe.

Thanks guys! It looks like the metal strap that comes off it it across the bottom has a bolt to the engine. Is it just mounted wrong and I can turn it? If so, anyone have a pic of the correct mounting up close?

You can't just turn that muffler horizontal. The bolts holding it to the engine won't line up. WH used mufflers that attached to a pipe nipple between it an the engine so I'm not sure what's up with that set up. Doubt it's WH factory but maybe someone else's factory. I don't ever remember seeing a maroon hood tractor with a vertical muffler but I'm no expert on the newer stuff.

Wheel Horse tractors of that era used that vertical style muffler when it had a K series engine. 

 

Tractors with the Magnum engine had the horizontal style muffler. 

 

Wish I could help with your snow blower dilemma!! The belt situation does seem odd.

Typical muffler on 1985 and 1986 single cylinder Kohlers.

[JCM 10,370]

1989 with Magnum and 1986 with K-series muffler configuration.

Maybe you could only use the single stage blower on the tractor?? The belt setup seems to be different on a single stage. 

 

I guess you could swap to a pepper shaker muffler to clear the belt, if you can get the allen bolts out of the block. 

 

Not the best situation, just an idea.

Gravely muffler works too. 

That's what's on my C160 Automatic.
