    Mower Deck on a 312-8

    So, after looking at the parts list and then searching at Toro, it appears that I may not be able to use this deck with this tractor with out some modifications including welding, which I don't/can't do myself. For one thing the leveler in the front interferes with the deck drive belt, which explains why it was put thru the support arm assembly with nuts, instead of threaded thru the tab on the arm where it's supposed to go. I don't think the lift arm on this 312 will work with the lift rod for the older deck.

    Mower Deck on a 312-8

    I pulled the deck completely off. I found he had 2 lengths of chain bolted together that went from the lift rod arm down to the deck bar. That length attached to the adjustable eye bolt on the lift rod arm was 4 links long, the length on the deck was 5 links long, and when he bolted them together, he bolted 4 links on each together and left the fifth on dangling. He also gave me a lift rod that looks identical to the one on my 74, that goes into the frame near & under the seat and it has 2 holes in it where it would go over the deck and a little further towards the front end of the rod is a pin that would go into a hole or slot on a different deck I am guessing. I am thinking that he made one deck from parts of several because I am finding too many things that just don't seem to belong, like the wheel height adjustment. I cannot set them into the lowest position because the bracket for the center wheel hits the deck and it would need another 3/8" of travel space in order for the height adjusting lever to lock into that slot. Then I look at that same axle, and it is against the rear of the deck in the center, but the 2 mounting brackets on the ends of the axle that attach the axle to the deck appear to be home made or something. They just don't look right. I am downloading the file you just sent now. I will check it out & maybe I will take and post some picks of the deck so you can see what I am talking about. I am not sure if I will ever get this deck onto this tractor so it will be adjustable. Thanks! According to the download file, I have part #24 the mower support, but need parts #25 Lift rod, #27 nut, #28 Lift St, and can probably use parts # 35 & 36 Leveler & nut, IF I can locate them. Also parts 73, 74 don't look the same as what is on the deck now, and part 38 on my deck looks home made according to the parts picture you sent me. I am guessing the angle he welded them on is off by the 3/8" I would need to put the wheels at lowest setting, not that I would ever cut that low anyway. Thanks again for the great info and all your help.

    Mower Deck on a 312-8

    Good morning Gary. Thanks for the files. I have downloaded them and will start going thru them, but at first glance they appear to be files I already had. Made some room in the garage yesterday and spent all day tracing the wiring on my 74 and finally got that running again. I also put the 88 up on ramps and messed with the deck. While I still don't think it's correct, I did manage to get the deck up higher so that it shouldn't scalp my lawn anymore by putting the rod in the top hole and over the raising bar at the back, but won't know until I get a chance to test it. I did take some pics & am going to try to upload them from my phone so everyone can see my problem. I found 3 tags that were either painted over or were removed before painting. The one that shows white was where I tried to get the paint off to see if it was readable. I just realized that I didn't mention, the deck on the 88 has a round bar attached to brackets on both ends of the deck at the front for lifting. Also I noticed that the rear center wheel bracket appears to be a home made bastardization as you can see the part that was cut and welded, combined with a steel patch at the right rear wheel attaching point, and if I try putting the wheels into the lowest position, the top of the bracket hits the back of the deck housing and would still need to go another 3/8 of an inch before the lever could lock into the notch to hold the adjustment. I think the deck is either much older or later then the tractor. I have never come across a deck with the round lift bar at the front before. Most of the files you posted all show the flat or square type bar stock with holes and pins for the lifting mechanisms, which is the same as what is on my 1974 and was also on my old 1971.

    Mower Deck on a 312-8

    Here is the only info I can find on tags on the tractor so far: Wheel Horse 312-8 Tractor ID # 2112K805 29480 Engine: Kohler 12 Magnum Model: M12S Spec: 471527 S/N: 1730108263 Deck: Unable to find any tag on it to identify it so far. Will have to take the deck off I guess to check it more thoroughly, in case there is a tag someplace where I cannot see it while mounted on the tractor. The deck appears to have been restored with new paint and some plates welded onto it at the back where the rear wheel axle brackets are bolted to it. I am guessing that it may have been a label type tag mounted somewhere along the back & it was either damaged and removed during repair. The weather has been nothing but bad here the past 3 weeks with rain & high humidity & I have no room in the garage to work on it, so I am going to have to remove the deck outside between storms, and check closer for a tag and will take some pictures of the mounting & lifting set up and attempt to post them here in the hope that someone can give me some info on the deck. The 2 files attached above in this thread here both appear to be the identical deck as the one on my 1974 or 1975 (Still not sure which year it is, because I have a 74 parts manual & a 75 owners manual) C100. I am currently working on an electrical wiring problem on this one. The 2 wires on the left side attached to the Clutch Safety Switch have gotten sheared of somehow with about only 3/4 of an inch of wire left on the connector screws. Damned if I can find the rest of the 2 wires on the tractor to repair them. As I said the weather has been very much against me the past few weeks here so working on it outside has been catch as you can. One thing I noticed about the OEM wiring diagrams I have found for this tractor, all show a seat safety switch, but neither one of my 2 tractors have a seat safety switch. The numbers on this one are: Tractor Model # L 0990 9 S/N: 47404 Engine: Kohler 10 HP Model: K241S S/N: 6097616 Spec: 46636D Deck: 0542M505

    Mower Deck on a 312-8

    Gary, the pic on the second file Mower Rotary 42in SD 1998 78345 3-400 IPL.pdf Looks exactly like the deck on my 1974 C100. I have downloaded the first file shown here & will check that one. Thanks.
  6. I recently purchased a 1988 312-8 w the Kohler Command 12-S engine. I was told by the seller, that it was a newer deck than what was originally on the tractor. I cannot find any number anywhere on the deck for identification. This deck appears somewhat smaller and slightly different in shape than the deck on my 1974 C100. Also the C100 has a deck adjustment/lift system that works with bars/shafts & adjustable trunions. The "newer" deck has a flat bar going from the tractor frame at the front of the deck, to the rear of the deck & is lifted near the middle of the deck by a chain. The flat bar at the rear of the deck is riding on top of a shaft which is through a set of holes on the bracket attached to the deck. There are also several sets of holes in the brackets, which I am guessing are for changing the rear height adjustment on the deck. I noticed the difference and asked the seller about the bar/shaft & trunion system on my older model, & he told me he had the bar that belongs on this one, found it and gave it to me, but I am not sure if this even belongs to this style of deck. It also does not have the linkage/adjusting rod & trunion with it. I have 2 questions about this: 1) Shouldn't this flat bar be riding UNDER the shaft to lift the deck, as opposed to on TOP, of the shaft? (It appears that the shaft is supposed to slide along the bottom of the shaft of this shaft instead of the top of it & that is why the deck doesn't raise up, as the height adjustment appears limited by the length of the chain link that has the fastening bolt through it.) 2) Can anyone tell me where I can find a downloadable manual for deck installation/removal & adjustment for this tractor. Any hints or help with this would be greatly appreciated.

    Just got a 1988 312-8

    Achto & 953 Nut, thanks for the info ! 953Nut, It was that set bolt that holds the shaft bearing into the hole. It actually had stress fractured where it was a smaller diameter where it meets the threads. I took a grade 8 1/4 x 20 bolt, machined the threads down at the end of the bolts, until the diameter was thin enough and just long enough to bottom out in the collar hole, left the hex head on the other end and used a double 1/4 x 20 nut set for locking it into place! It was so loose after the end snapped off, I was able to unscrew it w my finger tips ^ the smooth end was just lying in the threaded hole & had to be pushed out with a pin. Thanks for the great pics!
  8. Just got a 1988 312-8. No markings on the deck, but I know from what the seller told me and also from other decks I have seen, that the deck is from an older horse. I had been using a 1974 C until the other day when mowing, I went to change from forward to reverse and the shifter lever just came out of the trans mission into my hand! Anyway, I am trying to locate a Service/Repair manual for the 312-8. Anyone able to point me to where I can find a downloadable PDF copy? I have already found the electrical & parts manuals for it and now just need a service/repair guide. Thanks
  9. When you say drive belt, are you referring to the one under the cover on the side? I will check the clutch spring as well. I had to completely take the deck apart last season and clean it thoroughly because of rust & crud gumming up the sliding mechanism. I also know a lot of the rods, pivots etc are worn and need some adjusting & or replacing as well. The tractor just seems to move a bit slower as you go along & it gets hotter, but no change in sound or feel of engine. I am guessing it is the belt if not the transmission oil leaks & whatever oil he had put in there before selling it to me. I need to find parts sources with decent pricing and fast availability & delivery times now that I found some good manuals from the replies here. Any places you prefer to use for parts? By the way, Bethel CT here.
  10. Thanks! I do intend to do just that as well as put the new carb on. I am guessing that the original carb was messed with to the point that you can't set it as well as you should be able to anymore. Any tips as to places for ordering parts? The engine seems to run pretty good, and I possibly didn't describe what I mean by sluggish. It seems that on start up and first beginning to cut, the thing moves along at a good clip. But as I am mowing and it gets hotter, the speed seems to get much much slower. The engine doesn't seem to sound any different, like it's missing or slowing down or racing, just the tractor seems to be moving much slower the warmer it gets. That's why I was suspecting the gearbox and fluid, because of the oil leaks and not knowing exactly what oil is in it to begin with. I very much appreciate any tips, hints or clues. I have been so darned busy here lately I haven't even had a chance to pull it out & start it yet as I am swamped with work around here and getting older & slower! I do know I need one or two of the belts replaced, the carb changed and the leaks fixed though. Just a matter of figuring out the exact part numbers I need and finding where the best place to get them is, price wise & speed of delivery wise. The front tires were leaking air since I first got it, so I pulled them & put in those "Slime" tubes and they work great! Hated the thought of getting new tubeless tires when the treads were still so good. A lot of small quirky stuff to be done on it though, like having to wiggle the shifter or roll the tractor a bit once in a while to get the gears to shift. I have been my own car mechanic for 46 years now & the only thing I haven't done on a car myself is rebuild a tranny. There tractors are completely new animals to me when it comes to working on them though. I suspect maybe some spacers are worn or missing causing the shifting glitch, or possibly some of the linkage points are too worn & need replacing. I had hoped to do a tear down on it this past winter, but time and a few health issues put the cabosh on those plans, & suddenly it's time to cut the grass very soon now.
  11. Belts are one of the problems. With what I had found before the info I got today, I ordered 2 belts and only one of them fit. Can't remember if it was the main belt under the side cover that fit ot not. Am printing out the manuals I got here today and will be going through to find the right belts for replacing them all.
  12. Sparky, Ed & Garry, Thanks for the really fast replies and for the great files! Much appreciated! I had a 1971 horse years ago that was quite old but did a great job until it died on me. It was pretty old and not very well kept when I bought it from the son of an old man that recently died, and the deck was perforated all over beyond repair too but I loved the power and the way the 3 blade deck cut the grass. After that I had a new K-Grow which sucked, got rid of that the got a new Craftsman which sucked even worse, so dumped that in favor of this old horse. I want to redo the transmission case gaskets (I think it was put together metal on metal w/o a gasket) & seals, and hope to be able to find the sheet metal covers for the deck belts & spindles and possibly some wheel weights for it, since it seems to want to spin the tires too much. Hopefully the case overhaul and new heavy oil will eliminate my sluggish performance. I love the old horses!
  13. I purchased what I was told by the seller, to be a "partially restored" 1975 C Series. I have it now for 3 seasons & have concluded that this restoration consisted of replacing a few bolts and repainting it and replacing some of the decals. The seller told me he "screwed up" on the Model Decals when he ordered them, & put the wrong one on it (C120), but did not tell me the correct one that should be on it, and he gave me a 1975 C Series Owners Manual with it. I am wondering if the Model Numbers correlate to the horsepower of the engines. If that is the case, I must have a C100, because mine has the Kohler 10 HP engine, which is labeled as a K241S. It has an 8 Speed Manual Transmission. After getting it home and using it, I put it in my shed & the next time I went to use it, I see the transmission/gearbox has leaked oil onto the shed floor, appears to be coming from the seam between the two halves of the rear-end. I also see a heavy black greasy film build up at both axle seals & also around the brake drum seal. I am now in doubt of the recommended oil for the rear end. Some of the online forums say that they had begun using transmission fluid as a replacement for older types of lubes, while others say 10-30 motor oil. I saw someplace which I can't seem to find again right now, that 85W-140 gear lube was what should be used. The oil level on the dipstick has not dropped to low levels, and appears to be motor oil, so after searching around and also checking the manual given to me with the tractor, I top off the level with 10W-30 as spec'd on page 5 of the manual(if this is indeed the right manual for my year and model). My problem now, is that last season, it suddenly seemed to get a bit sluggish & slow down as it gets warmer during use. I believe my sluggishness problem might be due to the leak in the box seam and possibly also the type of fluid/lube in the case of the transmission/gearbox. I had already tweaked the carb as best I could, changed the fuel filter, replaced the spark plug due to a hard starting condition and rough running, & it seems to be running fine right now except for a backfire when shutting it down. I have purchased a replacement carb for it that I have to put on now, & I am pretty sure I need to locate & change the points as well. Anyway I am hoping that someone can point me towards the right manuals, by placing all numbers I have been able to find on it here so I can hopefully find the right service/repair manuals (hopefully as free downloads someplace online) for the different systems. Tractor: Model: 103909 Serial Number: 47404 Engine: Model: K241S Specs: 46636D S/N: 6097616 Deck: 0542M505 All Numbers on Transmission/Gearbox Casting: A24 8163 or B163 ?(Cannot Read Clearly) 101761 or 1017G1 ?(Cannot Read Clearly) Any and all advice/info anyone can supply me with on this would be greatly appreciated! Also, any tips on good places to purchase reasonably priced parts would be good as well.
