mavfreak 11 #1 Posted September 21, 2010 Ok I need some help. I have an '78 C 161 and I need a mower deck drive belt. I don't have any identification numbers on this tractor. It didn't have a deck when I bought it and I just bought one but I need a belt. So if anyone knows what length it is so I can go and get one that would be great. by the way I did a search on here and just couldn't come up with a definite answer. so even if you could point me in the dirrection of a post that answers my question that would help also Thanks Share this post Link to post Share on other sites
B-8074 20 #2 Posted September 21, 2010 How many blades and are you looking for the motor/pto to deck or the belt for the deck only? It might also help if you could post a pic of the deck. Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,474 #10 Posted April 7, 2013 Suspect your deck is a 1979 model 95-48MS00 with the 8306 build date being Thursday November 02, 1978. The last 2 digits in the model number are zero's. 13706 is the serial number. Drive belt Toro 102742 nla Use 94-2501 {HA/Ax103"} 6378 Gates 1/2"x103-1/4" 40 degrees 6378 Napa 1/2"x103-1/4" 40 degree Spindle belt Toro 1594 {HAx107.21"} A105 Gates 1/2"x107" A105 Napa 1/2"x107" We do not have the 1979 manual but do have the 1980 which should be the same 05-48MS01 http://www.wheelhorseforum.com/files/file/904-mower-rotary-1980-1983-c-series-mowers-om-810306r1pdf/ Garry 1 Share this post Link to post Share on other sites
GlenPettit 1,717 #11 Posted April 7, 2013 Wheeliehorse: Can you double check your tractor & deck 'Factory ID' numbers, I think you may have a 1976 C-120, #61-12K801 Wheel Horse tractor. The numbers you gave for the mower deck don't seem to match up with any I can find here. (ie: 1976 - 42" SD mower is #65-42MS01, and a 1975 - 42" SD mower is #5-1011, a 1976 - 48" SD mower is #65-48MS01), let us know the width of your deck, if you think it is original to your tractor and if SD or Rear Discharge. (the 48" SD uses 3 #100202 blades, a #1594 Spindle Belt, and a #102742 Mower Drive Belt [103" long, HA = 1/2"W and 5/16" Thick] ). Share this post Link to post Share on other sites

wheeliehorse 1 #14 Posted April 15, 2013 the tractor is a 77,, to be honest the first part of the deck identification tag was under a bolt and after i removed it i couldnt make it out and jsut took a guess at it,, but besides the very first number i could make out clearly all the other numbers, and to everyone thanks for the help, i appreciate it, as it turns out my neighbor has a lawn care company and had some extra belts and one of them worked. im guessing the belt deflection is a 1/2" at center from both pulleys, i think gwest had it right with it being 95-msoo ,, the tractor was built built january 7th 1977 do you think my deck might not be original? or maybe it jsut sat at a dealer for a while then they just put the 78-79 deck on it ???

gwest_ca-(File Mod) 11,474 #15 Posted April 15, 2013 That is the beauty of Wheel Horse products. The mower decks are basically the same 1973-2007 and 2009. 5-1202, 5-1210, 5-1211, 65-48MS01, 65-48MS02, 75-48MS01, 75-48MS02, 85-48MS01, 95-48MS00, 95-48MS01, 05-48MS01, 05-48MS02, 05-48MS03, 05-48MS04, 05-48MS05, 05-48SC01, 15-48SC01, 15-48SC02, 15-48SC03, 78360, 78361 Garry Share this post Link to post Share on other sites
wheeliehorse 1 #16 Posted April 30, 2013 lol yeah i see what you mean, i happened to get some parts of another wheel horse and took a quick look at its mower deck, it was an 80s model and had the same looking deck,, Share this post Link to post Share on other sites
Bluffhunter 37 #17 Posted June 2, 2014 I am also looking for the correct belt for my C-161 but I keep seeing the 102742 ( 1/2" x 103" ) listed for a twin cylinder engine and a 109956 ( 1/2" x 103" ) for the single cylinder Kohler engine. Tractor : 91-16KS01 Deck: 0542MS05 Toro can't seem to find in their books the belt I need, which I assume would be the 109956. I have just ordered a Stens ( True-Blue Belt # 248-102 1/2" x 102" ) brand belt to see if its the length I need, but would like to get an OEM Wheel Horse belt. Any other C-161 owners with better information ? I appreciate any input on ordering correct belts for these tractors. Kyle Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,474 #18 Posted June 3, 2014 The 109956 belt is 1/2" x 102" and used when the deck is mounted on a front mower carrier. The 102742 belt 1/2" x 103" is the correct drive belt for under the tractor. Nothing like an original parts list Garry Share this post Link to post Share on other sites
Bluffhunter 37 #19 Posted June 3, 2014 Thanks Garry ! I still can't quite understand why on some of the files ( not the one you attached ) it calls for a 109956 for a single cylinder and a 102742 for a twin cylinder. Maybe I will luck out and the 1/2" x 102" I ordered will still work, or if nothing else it will confirm that I will need the 1/2" x 103". I wish my father ( original owner of the tractor ) was still living because I know he ordered the tractor new in 1979 with a mowing deck, and the deck that's on it is apparently an early 80's deck. Can't ever remember him replacing it at any time, but he must have. I appreciate you posting the 300 & 400 Series file ! It will now be in my book of knowledge.

gwest_ca-(File Mod) 11,474 #20 Posted June 3, 2014 This is the bulletin on the front mower carriers that shows both belts. Manuals at Toro are shared by similar models but often fail to tells us what fits what. Sounds like they are sharing more than they should. Garry Share this post Link to post Share on other sites
Bluffhunter 37 #21 Posted June 3, 2014 Thanks Garry ! That is what I was talking about reading before that was confusing as mine is a single cylinder ( if they are talking about engine, not the hydro cylinders for raising and lowering the deck ) and that's what it says on the last file I downloaded. 42" SD (05-42MS) Single Cylinder 109956 (Supplied with C & GT-Series Mower Carrier) I will report what I find out when the 1/2" x 102" belt comes in. 1" may or may not make much difference with the adjustment on the mule drive. Thanks again ! Kyle Share this post Link to post Share on other sites
