Congrats on your purchase! I purchased a 312-8 last year off Ebay sight unseen. It's a great tractor! Here's a picture:

I'm not familiar with the C-121. C-125s were made between 1980 and 1982. They had a 12 hp Kohler and either an 8 speed manual or hydro tranny.

Mith is a Wheel Horse fan who lives in South England. He'll probably see your question regarding spare parts in the UK and respond.

Evening Albion,

As Deerslayer said, I'm down south. Where abouts are you?

I get my spares from the local mower repair shop. Might be worth you popping down to yours, if he cant sell them to you himself he will probably know someone who can.
Ebay is your other resource for parts.

If I am looking at the right listing you are going to be needing a front wheel bearing. I think if you get the inside diameter, outside diameter and width you should be able to get a generic one to fit from any old shop that sells bearings.

You can download a parts list and manual from toro's website using your serial/model number. I'll find the link sometime for you.
Found it ( https://lookup3.toro.com/request/request.cfm )

What do you have planned for it?
Quality bit of kit.

The C121 is basically the older version of my 312-8. Alot of parts will cross over.

I have 3 or 4 Wheelhorses now, cant remember. Its hard to have just one :-D

I have a Wheelhorse 312A, but it wasn't made by Toro. If the C121 is an older version of a 312A..........I thought mine was 1984 vintage.

The Wheel Horse company was purchased by Toro in 1989.

The C120 was a popular machine from about 74 to sometime in the 80's. I had one I fixed up back in the early 90's but had to leave her behind when I moved to another state.

I believe the C120 Auto was the direct decendant of the Charger 12 where as the C120 Manual was the direct decendant of the Raider 12.

The C121 is a slight variation. I think it has a different engine, not the usual Kohler in the C120. What engines does your have?

Or it may be the hydraulic version of the C120.

I am fairly certain one of the above is the difference.

Enjoy :)

I did some research. The C-121 was built in 1978 and 1979. They have a 12 hp Kohler and an 8 speed manual tranny...the same as my 312-8.

Yup, the C121 is basically the same as a 312-8. It obviously has the older Kohler 12HP.
In what way it differs from the C120 I dont know. More guages or something maybe?

My old 12hp Kohler ran well, but was using a 1/2 qt. of oil about every 3 hours. The local school district was selling off their old inventory and I picked up a 312-8 that was used to pull the wagon around during the football games. I got it for $200 and the motor was almost new.

Anyway, I have the old 12hp engine sitting under the shed. It's hard to believe how heavy that thing is. It's like lifting a solid piece of steel.

I figure I might as well keep it, just in case I need a part off it.

Does your C121 have a hydraulic lift?

Its a gear drive, so it wont.

Actually, I take that back, there was a hydro version in both 1978 and 79.

Believe it or not there are pulley drive hydraulics on some just for the mower deck.

However the "1" may represent something else.

Electric PTO perhaps? My 1976 C120 had manual PTO and an AMP gauge. No hour gauge.

GREAT BUY. I BOUGHT A C121 AUTOMATIC NEW IN 1978. BEST MOVE I EVER MADE. I HAVE USED IT AND MISUSED IT,AND IT STILL RUNS. I STILL MOW WITH IT AND PLOW SNOW WITH IT. THEY DON'T MAKE TRACTORS LIKE THOSE ANYMORE.ENJOY!
