which tractor is bigger JD 830D or IH 660D
 

hey guys, im wondering whats a bigger tractor in general, these JD 830 diesels which are worked and always win the pull, [the non painted one always wins] or my IH 660 diesel, the 660 pics are from google images exept the one in the garage, thats mine:biggrin2: mine has a working TA, and is a long tractor and weights about 9000lbs or more according to specs [bare tractor]without weights, mine has weights and filled tires. the 830 is about 8000lbs or more i cant seem to get a exact answer, but i read the 830 was the 660s competition and the 660 was a bit ahead of its time, the 830 has 76HP. i read mine can reach into the 90s HP if turned up injector pump which mine has , just looking for opinions, my opinion is the 660 is bigger, what do you guys think? mine is ready to go and fully serviced and will be pulling this weekend , also read the injector pump turned up can reach 30 more HP mine is turned up, i think one of the 660s in the picss was auctioned off ,

I have never seen a 660IH in person but I have seen a 830 Deere Diesel up close and them things are monsters for thier day and time.

i agree, but i believe the 660 is heavier and more horsepower, also longer, but cant guarantee anything

Is the 660 on the same basic frame as the 460 and 560's with just a larger engine? Where abouts in NY do you pull that beast at?

the 660 has the same frame i believe as a 560, same engine,model D282, exept the pump makes it have more HP and its bigger, [muh more heavier] we will pull with the 660 for the first time in our club this weekend on long island

the 660 is much heavier than a 560

the 560 spins up to 1800rpm, the 660 spins up to 2400rpm i think

The 560 and 660 had different rear ends. The 560 had bull pinion final drives, the 660 had planetary finals. 660 was only offered as a "wheatland" style tractor. 560 Diesel, high idle no load, 1965 RPM. 660 Diesel, high idle no load, 2615 RPM.

wow thanks jonathan, so which is bigger 660?:bigthink:

Toss up. VERY comparable tractors. 660 is heavy, and has higher RPM, JD has more cubes, and you can lug the motor to near stall... tough call. I am nothing but a IH tractor man..... but the Deere 830D will give you a run for your money. You gonna pull the 660?

The John Deere 830 can weigh in between 7850-11995lbs....and pushed out 67.15 hp at drawbar and 72.82 at the belt.

The IH 660 is about 1000lbs heavier than the 830 but itd be a toss up because of the engine the deere has.

i agree with shaner and jonathan, john deeres lug down to near stall, but a ih 660 is heavier and as max 71hp at the drawbar and similiar to the 830 at the belt, they are close calls:bigthink:

the 660 specs say between 9000 and 15000 or so sounds like super heavy but that would be ballasted, mine has filled tires and 3 wheel weights on each side

Per Tractor Data:

JD 830D

Weight: 7850 to 11995 pounds
Drawbar HP: 69.66 hp


IH 660

Weight: 9635 to 15255 pounds
Drawbar HP: 70.21

You talk about the IH possibly weighing more than the JD, :bigthink:

then why do they run the tractors across a scale at a tractor pull?

The machines should be identical weight.

The big flywheel on the JD is the difference, that could come close to doubling the power when it is "needed".

I spent hundreds of hours on a JD 820. In tight ground the JD would outpull the Case 930. When the torque was not needed, the Case could run away.

Both tractors were pulling 4 - 16" JD plows.

That and the fact that the Deere motor is almost 2X as big. One cylinder on the Deere= 235ci. TOTAL ci on the 660 ..... 282ci

i know guys, i saw those specs too, wasnt sure they were accurate

both were brutes of the prairie...for sure

cant wait to see your results, naturally the IH will win hands down lol

I'm a Farmall/IH guy. John Deere saw the writing on the wall with the two cylinders, that's why the 830 was the last two cylinder. :biggrin2:

That being said, Dad has a 730 electric start diesel. Nice tractor to play around with. Now I did say I'm a Farmall guy.

Nick, I've got four numbers for you to think about:


1206


I can hear the turbo whine..................:beer2:
Nuff said.:biggrin2:

The unique thing about the JD 2 cylinders was fuel economy. The 830 was generating 17-18 horsepower-hours per gallon, while the other 4 and 6 cylinder engines were producing 12-14 horsepower-hours per gallon or even less!

Doing 40-50% more with the same amount of fuel meant a lot when you could not get diesel!!

There were several stories about farmers in the early 1980's parking their new tractors, and buying restored JD 820's for field work, just because of how little fuel was required.

I do not have the exact #'s, but, my BIL would dump 3 five gallon cans of fuel in the 820 after lunch, and I would run that tractor the rest of the day pulling a 4 bottom plow.

The 4630 would have gone an hour and 20 minutes with that much fuel. (11 gallons per hour!)

before you go slandering the two cylinder john deere engine....watch this video. i was impressed. i do like those old Farmalls, wish i still had the H that i had. they were very fun tractors to tool around on. i had a super M with a snow plow on it for a brief time too. never got a chance to play with it though.

I didn't slander the deere. Just stating the 2 cylinder was becoming obsolete. John Deere did pretty well with the next generation tractors: 4010's etc., that replaced the two cylinders. First tractor I restored was a fence row 1950 John Deere B. Dad still has the B, a wartime A, hand start D :bigeyes:, and the 730D. He also has a lot of IH's.

The old saying was with a pair of pliers, screwdriver, and roll of wire, a farmer could keep a two cylinder running for years..............:biggrin2:

Cad,
There are a lot of two cylinders still out there being used on the farms. I also see a lot of old Farmalls running augers, pulling wagons, etc. Dad's 730 does sip the fuel. My 782D sips the fuel, too LOL! You could pretty much fit the whole Kubota engine inside of one cylinder in an 830!! Kinda funny.

Im not going to lie I do love the 820 830 JDs. They are truly a force to be reckoned with. But I did grow up driving one.

the 600 diesel i have pulled 17 blocks that are about 800 pounds each and the sled is 2200lbs, the 660 pulled 21 blocks that are about 800 pounds each, but on saturday the stick shifter locked up but we fixed it , it pulls pretty good:beer2:

ok we had the stick shifter welded up on the 660 and grinded back down, last weekend we added more weight to the back then borrowed more weight frome the JD 830, we pulled 22 blocks both days, the 660 took second place as there were not any really big tractors , the JD would of won but we pulled every block barely that they had out and that was 22 blocks, they usually have at least 30 blocks, TA works good and the front end was coming up, heres my brother and our friend pulling on my 660, i have a pic of it pulling up to 21 blocks, dont have a pic of 22 blocks but it pulled it half way, then they hooked the 830 to the other end of the sled but it couldnt pull it lol heres my friend on the 660:beer2:

here he is again on the 660:beer2:

blocks are about 800lbs each

my brother on the 660:beerchug:

my brother doing a wheelie while pulling the sled:beerchug:

20 blocks on the sled

21 blocks on the sled

total weight it pulled was around 9 1/2 tons:beerchug:

Nice pics Nick!:beer2:

thanks mike:beerchug:

Great pulling pics, Nick!

thanks allen, yea :beerchug:they look great
