Super 88 how big of a plow?

fixerupper · Jul 20, 2018

First things first, I live in an area of Iowa where the soil is good and black and pulls hard.

My neighbor claims they used to have a super 88 with oversized pistons that had 75 HP and could pull 4X16's 8 inches deep all day long. That's almost a direct quote from him. I say bunk! a super 88 could be weighted down for the traction and I don't doubt the 75 HP and the ability to pull 4X16's for a short time but in my area a 4X16 plow is usually found on a healthy 1850. I don't think there is any way they could have kept that 88 cool with that kind of horsepower and load. I have a straight 88 with 52 HP that is very comfortable with 3X14s in our soil. I have three weights per wheel but the tractor still feels light. The radiator seems at it's max capacity at 52 HP. What do you Oliver guys say about this?

Our 88 gas has oversized sleeves and pistons and was dyno'd at the dealer back in the 1960's at 66 PTO HP. Never had a problem overheating from what I was told. It
was the main tractor that way for several years until the 4010 Diesel came along. I will say that upsized tools were never bought for it. I remember one time I chopped a
load of corn silage with it using a 2 row chopper and it probably was around 55-60 degrees F and for that load she did not heat up. Run several hours like that probably
not.

Need more comparison info. If it could do it for half an hour, there is no reason it could not do it all day long - machines don?t get tired!

Tyre size, gear ratios, real world soil comparisons, type of plough and condition of same. I know my 90 used a lot more power on spade lugs
than pneumatics, but went better on steel than rubber when conditions precluded using rubbers.

They may only plough slightly slower to reduce the total number of horses deployed, but still cover as much, or more, land than only 3 bottoms
at a faster gait. Maybe more energy was rejected as exhaust heat at those higher horse powers, so the radiator wasn?t so much more loaded.

I certainly wouldn?t want to call him a liar - he may even have been a better ploughman than you.

What does he use now?

My uncle wasn't one to overload things,but he only pulled 2x16s with his straight 88 diesel. I'm with you though,with the weight of those tractors,in heavy ground,3x14s all day would be a good load.

Well if you went down to corner here and turned right and went about 8-10 miles a Super 88 would do that. Now if you would have turned the other way and drove the other way the same distance 2-16's were just right for a Super 88. Also interesting my employer was a diesel man. He sold close to 50 super 88 diesel tractors, but only 4 Super 88 gas tractors and 3 of them had the optional slow speed rear end where very few of the diesels did.

How much slower was the low speed rear end. Low gear on my 88 could be a little slower when it’s pulling a square baler in heavy hay. The baler does OK, it’s the guys on the rack who get the workout. I’m not thinking of changing anything, I’m just curious.

Claimed HP and Dyno HP are usually considerably different.Sounds like the size and number of plows got added to over the years.

Ya! The first time he told me the story the Super 88 had 62 HP. Several years later that Super 88 had 75 hp and could pull 4x16’s 8” deep all day long. They got rid of that tractor over 40 years ago so it’s not around here anymore to put on a dyno. The next time he tells me that story I want to tell him he’s full of it but first I need good backing.

Is it a gas? It would take more than just oversized pistons to get to 75hp at the pto. Did he say what gear he plowed in, rpms and tire
size it had?

Up here in northern IA we pull 3-16s with our overhauled 3-3/4 piston S88 diesel in heavy black dirt and it seems like a good match. Could
pull in third but the black smoke would roll too much so we kept it in 2nd. This tractor weighed 5,600# with no add weight added.
Slippage was an issue no matter the gear, especially in the low ground. If he really pulled 4-16s he would've needed lots of weight added
and probably a dual on the land side to get enough traction.

Funny how he said "used" to have. Tell him you'll believe him after he builds a similar tractor and shows you in person.

I run 3-14's with my Super 88 in some good black ground. It handles that load pretty easy.
I'm running 2 sets of rear wheels weights.

His 88 was a gasser, I forgot to mention it.

Back in the 1960's a neighbor had a Super 88 diesel with the pump turned up...We have easy
plowing soil and he pulled a 5x14 Case trail plow...It worked it to death...All he needed was 4x14's
or 3x16's..
