Registered: 04/01/2019 Posts: 13 |
I found and read some old disussions about rearends for small block v8 hot rod tractors. Cockshuts, MH 44 and others seem popular in those discussionns I found. can they or others be used successfully in stock form, or do they need modifications. what modifications are commonly done. |

most run a second tranny ahead of tractor transmission,to help not break gears,Massey's like to break third gear if run direct. |

would not

Would not recommend a MH44 rearend as they always spin one wheel out as nearing end of run, whereas other tractor makes will gain several more feet. Does not matter if talking a stock tractor or rearend used in any horsepower size Mod. Good luck in trying to ever win with a MH44 rearend. Cockshutt 40, 50, 570 have been the tough and most used rearend over the decades & still are in today's EconoMods. |

that's what they call it in a car or truck,regardless,-- it works, many 44 Masseys around the area,most don't have the power to run hard and win,but still out there running well. |

I know what limited slip is. Just didnt know that you guys use it in tractor pulling. I thought that you were needleing them to reduce power loss when on one of the brakes. Edited 1 time(s). Last edit at 04/03/2019 12:10PM by loganmh44. |

To each his own on factory Ag transmission and differential choices. I've run both Massy Harris, Ford and Cockshutt rear ends in modifieds over the years. I'll agree that the toughest conventional Ag rear end are the Cockshutt's as "Would Not" noted. The Ford differentials with inboard planetary' s are extremely tough, but the transmissions are weak if the rules allow you to run an Ag rear end with planetary' s. The Massey Harris 44's will hold up decent, depending on the weight of the class you're wanting to run. The best weight for a MH 44 is 5,200 lb. or less. Much more weight than that on them and they seem to fail. What are you class rules loganmh44? |

A 570 rear end is very strong,but must also be very heavy with all that material in there.I pull 6200 and 6500 with my Massey,I spin out - never pull down and use torque to break stuff,and having an extra trans ahead of weaker rearend takes the shock load first.That is what other successful people have found out and shared with me. |

I run a f20 rear end coupled to a turbo 400 with a manual valve body. Only broke one axle in 10 years and that was due to bounce. |

Looking at the COTPA they run small block all cast iron V8 at 6000 lbs. My deal is that i m getting out of circle track racing and have 2 SBC engines. They are .040 over 350. I have access to a MH44. Would probly be under power to be competitive but it would be a start to get my feet wet untill i can build the other engine to be competitive. I know there will be a lot of work to be done but i m looking for a "science project". |

I bought my tractor with a sbc 355 restricted to certain heads,it was fun and I changed some things to make it "MINE" to be more adjustable in several ways,Having Fun is key,Having a project is even more fun,we need to have a means to exhuast some extra energy.I was near the winners circle mostly and even won sometimes,but wanted a little more,so with a new custom tranny,more power,new slipper clutch and new hubs,tweaking and learning to drive -- I now have a really fun tractor that is amazing to drive and surprises many people.Having fun is key. Enjoy,-- bond with your tractor and learn it's personality and manage it to combine with yours to share fun times,make friends and go do it. |

just go with the massy 55..so much better.. have in a small block 500 hp...has rite gears .dont think you can tear this one out...the 44 rear end will hold up..but tranny is big issue...and by the way this tractor is for sale!!!!! |

Logan, I’ve never seen a small block compete with the big blocks. The reason being, is that they’re still limited to 6000 RPM. They would be way under cubed because the Big blocks are allowed 505 with one organization and 521 with another.
If the small blocks could run 8000 and be limited to 410,, I think they’d have something...But at this point they don’t do it that way... I believe the SBs in Michigan and surrounding areas run 8000...Not 100% sure on that but think that’s right. |

You’re correct. No one runs a limited slip or locked rear end, at least ones that know what they’re doing! A free rear end will pull straight |

We have a Hot Rod V-8. We run a big block class in eastern Ohio/Western PA. Limited to 6000 RPM. Sounds like you’re interested in the small block class though. I know there is one for sale on the for sale page. It’s an Oliver.
Toughness wise, the Oliver is great (it’s a Super 88/880). Gearing with 18.4x38 can be an issue. There are 3 different ring and pinion options for those. They all have their positives and negatives. We personally run the stock rearend from the factory. Know of 2 other Oliver’s that had gears made. All stout tho. Also know of 2 Molines (one is a U and it’s Heavy) 2 Cockshutt 40s - Probably one of the best rearends for this application from the factory Know of a couple Cockshutt 570s 2 Case 600s - These are usually top of the class because of chain drive and they’re just tough competitors Fords Massey’s Farmall Ms 4020 John Deere’s All is Chalmers D-17 You name it, it’s probably out there. Most guys re-gear them as I said but not all To each their own but if you have any more questions I can try and help you with what I know...Which isn’t a lot...Haha Good luck |

No problem. Also. One more thought on the Massey Harris 44. There’s a pretty good runner in our class and I know he’s re-geared. I also know that they’ve broken more than one. They almost switched to a different Massey model because they are getting harder to find but found a couple more donors so they are still running it.
Doesn’t mean they are bad rearends tho. Just what I know about that particular Massey 44. But they usually do spin out just one tire. But I’ve seen that work to their benefit actually more than once... |

Are the MH 44 having trouble with trans gears or ring and pinion. I have seen video of the BB tractors. Have any of the SB tractors ever run with you guys or is there rule issues preventing it. If they have how did they do. As for buying a built tractor now I have 2 SBC circle track engines nobody wants or I am asking too much for and I think i have a real inexpensive
44 so I thought i would go down that road. |

All I have heard and seen is the 44 Masseys break 3rd gear fairly easy when not using aux trans.Key is spinning out with out lug down |

The 550 would be a bit on the light side, in my opinion. I know of a couple 570 Cockshutts that run pretty well but never a 550. Not saying it wouldn’t work but would try to find a little bit heavier rear if you can. |

Are the Cockshutt 550 rearends any good for this type of pulling? |

My apologies. I thought the 570 was a heavier unit. If they are the same, then I’ve seen them in action. They run good and have never seen one have an issue. I know a Cockshutt rearend, typically is built very stout. But again my apologies. I thought the 570 was heavier built |

Massy 44 Oliver 88 m Farmall cockshutt 40 and several others will work. I run a Farmall 460. I broke lots of parts figuring it out a 560 would work. Find the tractor you like and build it. Have fun. |

I have some friends who use the 50 rear end with know problems but they get rid of the transmission |

Re: Massy 44 rearend

Yeah some guys keep the stock transmission, but others use a different transmission because of the age and the strength concerns of some. It’s pretty impressive what those old rear ends can stand when you realize that most are putting more than 10x the original power through them...But everything has its limits. But like I said. I know of at least 6-10 that run the stock rears. Some of them are very competitive too. |

logan, it’s really up to you on what you wanna do. If you have a brand loyalty (Sounds like Cockshutt or Massey) then find the strongest rear you can that still meets the rules. I know in the big block class that is run in Ohio and PA the rule says 72 or older. So guys are running even newer combinations. When ours was built the rule said 57 or older so we built a super 88.
In the Ohio/PA class most do not run the auxiliary transmission. Some tried it and found it just took more power to run it and they didn’t need it. If you are a good fabricator or have someone who is, you can build the tractor around the rearend. Again, that’s what many do in order to make the V8 sit in there nicely. You can always find a good foundation and start building. Then change it how you like. I hope you find something you like and get into it. It’s a fun class with great competitors. It’s a great way to revive those old fence row tractors Good luck and if you have other questions, you can certainly come on here and ask. Try to help anyway we can |

I’m not trying to get into an argument with anyone. There are many good options out there for a good foundation. And there are people much smarter than I that could help you get rolling when you’re ready. I’m sure some of the Central Ohio guys can help you so that you’re set up more for their rules. Good luck to you logan |

It has been mentioned before to build to specs where you want to pull.Makes perfect sense,that is why we all like and want similar rules so we can travel to a fun new venue to enjoy make friends and share passion for the sport. But if you choose to go on a personal journey and build outside the lines,-- then have fun,pull when and where you can and most of all have fun. Building,modifing and making it your own if you buy something is the happiness for me.Nothing in the wotld sounds as good as a well tuned and good running V8. |

Update. The MH44 deal fell thru. However I ended up buying 2 cockshutt 40 tractors. Thank you all for your input on the selection of a tractor. On another note does this mean I should change my user name? Can i change it or is it like getting your girlfriends name tattooed on yourself? LOL |

I really think that you made a great choice with the Cockshutt 40. They’re great rearends. Seemed to be geared just about perfect and tough as nails. You may have to figure out a work around for the steering if you use the stock steering but it’s doable. Best of luck to you.
As far as changing your name... I don’t know. Didn’t see a way with a quick look into it. Maybe you can create a new account... |

I can change it for you just email me (jakemorgan@pulloff.com) with what you'd like it to be and I'll take care of it.
As for usernames and tattoos I'd suggest "No Regerts" Jake Morgan Owner, PULLOFF.COM Independent Pulling News This page is a free service. The cost is covered out of my pocket. It takes a great deal of time and a fair amount of money to keep this website going. Donations for: photos, classified ads, forum discussion, etc... are appreciated. Side Note: We are no longer accepting PayPal donations. They have changed their terms of service and stated they would fine PayPal users for spreading "misinformation" and "hate, violence, racial or other forms of intolerance that is discriminatory". PayPal did not provide definitions for some of these vague terms. Woke corporate policies regarding "misinformation" could result in an automatic fine of $2,500 which would have been removed directly from the customer’s PayPal account. PayPal did backdown from some of their policies but quietly implemented portions of them in later terms of service. A financial institute has no right to monitor social media accounts or speech. This is unacceptable and I'll no longer do business with PayPal. |
