Cub Cadet 1512 diesel

[Beach]

I just recently picked up a Cub Cadet 1512 diesel! It has a d600-b 3 cylinder diesel in it, and I was wondering if anyone new much about these! I think they only made this model from '85-'87! Is it possible to turn the pump up a little without hurting it. I'm making a seperate exhaust stack for it just to put on for special occasions and fun also. I don't know what it would sound like, and don't know if a larger 3-4" pipe would be to much. It's just for fun and to mow my grass, but being diesel, I figured why not! Anybody who has maybe done this or has one that can point me in the right direction as far as good websites and videos, so I can hear and see what this will sound like! Thank's again!

LOL! Feel free to come check mine out in Iowa. Im running an RHF4 turbo on mine in a Cub Cadet 2084. What you have is a Kubota engine and can be modified for more HP.

How can you keep axles in that thing?

Dad has a 982( same drivetrain but with a 20hp onan gas engine) and pulling a plow just like yours it will anialate axle shafts! we have broken 5-6 of them with the plow. it will either twist off the splines or the flanged end If the splined end is gun-drilled!

Cryo treatment. To some it may seem extensive for a garden tractor but we use ours ALOT for heavy work.

Im a Cub collector back to the 1960's models. The round fender types. I believe the 1512 Diesel (which was made by either Cub Cadet Corporation or under MTD ownership as IH quit making "real" Cubs in 1981... the red body/red axle tractors) is a clone to the mighty 782 developed by International. The 782 is considered to be one of best ever made along with the JD 318 and a few others. The 782D had the Kubota D400 3cyl diesel. It was an alright diesel. Kinda neat. Won't do any more work than my 782 Kohler 17HP twin flathead gasser. But nonetheless the "cool" factor is way up there and I've been looking for one. They are rare... but out there from time to time.



Tractor-wise... your model is durable and capable. IHCubCadet.com is one site dedicated mostly to all IH models but discuss other years too. I've seen many videos of the D models pulling a 1 bottom plow at IH plowdays. Plowdays are a day when 100's of Cub older models show up to a huge farm field and all line up across pulling 1 bottom plows and turn the soil over better and faster than any huge modern farm tractor. They are fun to attend and those guys are as serious as any group you've EVER seen.



And FWIW... the old school Cub axles don't break. Its the same diff as a Farmall Cub tractor. I think the axles are 1" steel. I've seen up powered versions with duals, triple wheel weights etc etc pulling plows all day long. Competetion pullers love the Cub rearends. Its VERY RARE to see a Cub axle break. I've never seen one personally. The newer ones like you have may be made of lesser materials and have aluminum housings. But the Old ones are Cast Iron and built 3 times stronger than what a person needs.

I have decided to sell my 1512. I am asking $2000. Please pass it along if you know anyone into these!

Yep, I bought one of the last red Cub Cadet 782s built by I-H and used it to mow about 5-7 acres for over 10 years. I sold it to a friend after I bought a John Deere replacement with power steering, foot controlled hydrostatic transmission, and hydraulic lift which was easier for my wife to drive. The friend used it for another 10-12 years before selling to someone else. Neither of us spent any more on it than regular maintenance. As far as I know, it's still mowing grass. In fact the Cub Cadet cost less to operate all those years than the John Deere tractor that replaced it.



You are correct. The I-H built Cub Cadets used the the same cast iron differential as the Farmall Cub tractor. I-H sold the Cub Cadet product line to a spin-off company, The Cub Cadet Corporation, and they "cheapened" the tractor with cast aluminum and stamped steel instead of heavy durable cast iron components that were originally used.

I personally have busted MULTIPLE axles in cub cadet. the one in particular was a red 982 with bar tires and a homemade ROPS on it. 20 hp with a hydro and the axles DIE in a hard pull. at first we were busting the axles @ the splines. then we tried gun drilling the axles and then started breaking them @ the flange. the red ones use a coarse 10 spline axle which is the exact same axle used in ALL the shaft drive CC's. The yellow/white late models while using cheaper aluminum axle hors actually had BETTER axles in them. the late model unit had alot finer splined axles that didn't have the splines cut in so deep. The only way we were able to keep axles in that 982, was to swap in the later model axles.

I had a 1650 that I used in my rental business for moving trailers, air compressors, and even a 5000# wood chipper with its 300# tongue weight. It worked reliably for 16 years, and that's after working as a Chem Lawn tractor in its first life. Even the most brutal employees couldn't break it. It even survived the 1990 shop building fire which damaged everything from the hood level on up. It was rebuilt and repainted to new condition. When I got rid of the business I sold it for $900.

If any tractor was going to break axles, this should have been the one.

My Cub Cadet 782 rolled out of the bed of my '92 D350 CTD while going down a county road near my home in Denton County, TX at the time. Fortunately, I had just made a stop and 90 degree turn and was accelerating and only traveling about 10-15 mph. I heard a noise and looked in the rearview mirror and the Cub Cadet 782 was rolling and bouncing on the road behind me. Somehow the chain I had attached to it came loose. I stopped and the only thing wrong was the hitch plate on the rear axle had hit the pavement and pulled slightly away from the differential housing and was leaking transmission oil. I quickly put down the loading ramps and drove it back into the truck bed before the transmission oil had all leaked out. I Heli-coiled the bolt holes in the cast iron differential housing and no leaks or bent axles. What was scary, I had just exited I-35W and had been traveling 70-mph.

Must have been a genuine IH built 782 with the cast iron axles... usually painted red. If it had been 84 or newer 782 built by Cub Cadet Corp... it would have had an aluminum cast axle and it'd have busted all over the road.
