Need rear end info

[hdsdcouple]

Looking for a set of bolt in rear ends for a narrow frame cub. looking for some thing that can handle 25 to 30 HP engine. Planning a tractor build and want to line the ducks up 1st.

I am guessing stock rear ends can't handle that much HP.

Think you want to talk to dvogtvpe & Merk.

You should be good to go with a fine spline with bolt together carrier. Or to be safe look at midwest super cub's billet setup.

It would help to know if this Cub Cadet will be only a puller, if it is a puller what does the class rules allow and how deep is your pockets?

A set of fine spline axles and diff that austin8214 pointed out is a good place to start if the class requires a diff in the tractor. I know a few pullers in lower power class still using course spline axle with no issues. I would put a ring around a 1 piece diff housing to help keep the diff housing from spliting. My Son has a 2 piece diff and axles from a newer Cub Cadet in his wide frame Cub Cadet puller. He had to modify the bearing area on the axle housing because the axles were bigger in diameter

An internal brake trans/rear end has less drag than a disc brake set up.

If the class doesn't require a reverse gear I would set the trans up with 4 forward speeds with one tooth different in each gear. Another way to go is changing the gear ratio in the drop box. You can over/under drive the drop box up to 30%. If I 'm using stock shifter forks I like to weld shifter forks and install heavier gear shifter poppet springs to help keep the trans in gear. Along with the above I will install a system to lock trans in gear. Some will install stronger main shaft, main shaft bearing retainer.

wow, that is incredible. I guess I asked the question to the right bunch of people. That is going to take me weeks to break down all that info. And you just rattled that off. I have to bow to you sir. thanks for the info and I am sure I will have to ask more questions because I have a totally dumb founded look on my face right now.

We have no real pulling association here in South Dakota. I am wanting to build a puller, but doubt if it will ever go to anywhere were there is a serious pulling group. but I would like to build it to go play tractor puller. because after ready that post I can see I have no clue to what you guys are really into.

in that horsepower range the 2 piece carrier and fine spline axles would be a pretty solid setup. shifter lack is a must. I always recommend the steel front pinion retainer. its a must for any pulling. I've even put them in a few stocker rears for guys that just want to have a plow tractor or something they plan on abusing on occasion . lots of good advice from the others.

I think I fall into that group, "a plow tractor or something they plan on abusing on occasion", I think we have 3 garden tractor pulls in all of South Dakota all year.

going to look up some of that stuff everyone is talking about. see what I am getting into.

I wish I did live somewhere where I could pull a lot, looks like fun.

school is in session, looking at some of these products on Midwest super cubs. I can say for sure I am going to need some real help with this one. I am not to proud to say I am going to need help. lol

[dvogtvpe]

soooo what did you decide you want?

[hdsdcouple]

heck I am still looking at all this stuff. is mid west super cub the only place? are there other companies building pulling parts?

If so can you share some names.

Oh I am looking on extreme motor works also
