My 98 Wheel Horse 312-8

[Derek W 18]

I finally remembered that I hadn't shared a pic of my "new to me" 312-8.  It's got some rust but, all in all, it's in pretty good condition and it runs real well.  I'm currently hunting around for a muffler for it because the exhaust pipe looks like it was ripped off.  The tractor came with a large "stack" style muffler but I don't want to use it.  I'd really rather have an exhaust and muffler that sits closer to the engine.  

 

Anyway...here's a picture of my Wheel Horse

@DerickW , personally would get a lubrication soak  going on that paint , looks like a perfect  time to save and enhance  patina . like penetrating oil  spray down on all painted surfaces , let it soak / sit for days , before  using a clean cloth  mineral oil rub down . bet that will just  show you a very good shine , also like a 6" electric palm buffer , and a cleaner wax , also like mothers , back to black  enhancer . seat will be an easy swap , look on line , for matching  seat frame bolt holes size diagram .also get the rear end drained , like a hi mirage , atf  fluid as a flushing agent , put some miles on that oil  , use every gear , replace shift boot . rotella 30 wt oil . is very good in those . give it a thorough  grease job , also  aerosol red spray grease , on linkage / levers  . others will chime in  on , their own ideas , welcome  to the site , pete

Several people have been using a Gravely muffler and are happy with it.

Thanks for that flood of info, Pete!  I'm not going to be restoring this tractor.  This Wheel Horse will be one of the three tractors that my wife, daughter, and I will be modifying into mud mowers and trail riders.  I won't talk much about the other two tractors because they are different brands.  However, your mechanical tips have definitely been noted!  

I saw some mud mower videos, on Youtube, earlier this year and it really looked like a lot of fun.  There is just something about the look of the Wheel Horse and I knew that I wasn't going to be happy unless I had one.  Now that I do have a Wheel Horse, I am on cloud 9.

also get the rear end drained , like a hi mirage , atf  fluid as a flushing agent , put some miles on that oil  , use every gear , replace shift boot . rotella 30 wt oil

Since it is a manual use diesel or something as a solvent, still run it in every gear, and then fill it up with 80w-90 gear oil

I keep a spare jug in my garage just for diesel fuel, despite the fact that I don't own anything that uses diesel fuel.....it just makes a great solvent, as you said.

@Derek W   as you familiarize  yourself with your  unit  , important to make a regular  , check over ,  a way to spot anything that is different , example , when I use any  of my 3 , at finish , top up tank , add, a couple ounces sta bil fuel  treatment , never let the tank go empty , check the rear end oil dip stick , check engine oil , look for anything  , that might have given , you a sound or , functional difference , develop a squeak , or noise that was not there ? been doing that  for many years , don't even think about , a vey common  improvement  spot  clutch pedal  , function , should be smooth / easy with zero binding , or  sudden  jumping at  function ? like a penetrating oil first  , make the rust run out , then an aerosol  red grease , extension tube . for  exact  swing ease . how about your  choke and throttle cables ? smooth and easy . responsive ?  again penetrating oil , 3n1 is good , then after  its better , like a hydraulic oil , like SUPER LUBE , stays with it , incredible temp , function range . just ask , pete

All of that is incredibly helpful!  It's too much to make notes of, so I just took a screen shot of your entire reply and printed it out lol.  All of that makes immense sense to me and, although I did consider some of what you said, I didn't consider everything that you said.....but I will definitely check and recheck all of that.  Thank you sir!

@Derek W  we all look at the same thing differently  , bought my first horse in 82 , still have it , very often look at another similar tractor , with glairing  to me ,opportunity  to improve things , can only make a suggestion , like , repetitive problems  , ?  why ?  opportunity  to eradicate it , its always there , always does the same thing , like to roller stool around it , and make things better  .  also like to  protect my painted surfaces with  lubrication ,  another experiment  , years ago  , to this day , my tractors  get a  lubrication rub down , clean/ shine / zero rust , also oil  spray down my  attachment's , my mower decks'  are now  , cleaned and oil  sprayed , over winter  ,  months of lubricant  on a deck underside , eliminates , rust ,and stays with the metal . and don't call me sir ,  pete

If I remember correctly the 16hp Gravelys were a twin cylinder so twin mufflers - one for each side.

I would not want to use a single muffler on anything larger than 12hp.
