9N Weight

[Retcol]

I was wondering how much does a 9N weigh. I noticed in the Nebraska test the tractor weighed 3375 including 151 lbs. of calcium chloride in each rear tire. However, in the Ford N Series tractor book it said the 9N weight including gas , oil and water is 2410. What is correct?

 

[Dell (WA)]

Retcol......both are. When 80% full of recommended 115lbs of corrosion inducing calcium-chloride (CaCl) and 23-gals WATER, each rear ag-bar tire adds about 310lbs of tractor traction enhancing weight. To fill to 90% of 151-lbs of CaCl requires special equipment. Tractors left the factory with "dry" tires ......Dell

 

[Retcol]

I wasn't completely accurate in my original post. The Nebraska test said "151 lbs of calcium chloride solution in each tire". I would assume that means it was already mixed with water. Therefore, to me that would mean 302 lbs of the 3375 total weight.It seems like there is about 600 lbs of weight difference.

 

[souNdguy]

quit guessing and double thinking the good advice you have been given

look at this chart.. firt is tire size, then gallons of water to fill 75%, then added weight.. no ballast material.. so add # for ballast like cacl.

11.2-28 27 225

12.4-28 35 292

that pretty much explains it.

You can do all the preaching and provide all the information you want on solution in tires but this is what it says in the Nebraska Test No. 339. "Weighing only 3375 pounds, the Ford 9N was equipped with three forward speeds of 2.51, 3.23 and 7.48 mph. The test model was furnished with 8.00 x 32 tires plus 4.00 x19 front rubber. For added weight, 151 pounds of calcium chloride solution was added to each rear tire". As a result I think there is a difference in weight specifications.

 

[Bruce (VA)]

Dell gave you the answer & Soundguy explained it. Too bad you didn't understand either one. Rather than argue, it's not that hard to do the math:

2,410 lbs = tractor
292 water weight + 151 salt weight = 443 lbs per tire

443lbs x 2 tires = 886 lbs

886 lbs + 2,410 lbs = 3,276 lbs

 

[souNdguy]

and that's 75% fill. if we use the number for the 10-28 ( 11.2-28 ). and add exactly 6 gallons of water to each tire.. which prings it to about 82% fill.. then the weight works out perfectly.

[souNdguy]

it looks like you are just not doing the math.. add the water weight for 75% volume plus cacl then figure for each tire and you are a meer 99# off.. exactly 6 more gallons of water in each tire brings that to about 82% fill.. and makes the number work out perfectly.

I'm not sure what you are finding hard to reconcile about this...??

Those 32 inch rears where an option on the 9N and not a common size tires plus have you even tried to find a 32 inch tire now days?? They are next to impossible to find any more and to even see a 9N with that size on would be rare. Plus if you do not know ALL the Options that might have been on that tractor it is also imposable to guess what it would in fact weigh

 

[Bob]

The Nebraska Tests are pretty well documented, and I'd bet you could probably bet on their "as tested" weight for that particular tractor.

For comparison, I took a look at my 1952 Tractor Field Book, Tests 443 and 444.

443... 8N

They ran some tests with NO ballast. "As tested" weight WITH OPERATOR was 2717 lbs., and some tests with liquid ballast and cast iron weights, bringing the "as tested" weight WITH OPERATOR to 4043 lbs.

444... 8NAN

"As tested" weight WITH OPERATOR 2717 lbs. before ballasting and 3549 lbs WITH OPERATOR after ballasting.

So the "wet" shipping weight for a 9N of 2410 lbs. probably isn't too far off!

 

[Bob]

Don't forget the weight of the operator is apparently included in the Nebraska Test figures.

 

[Retcol]

I don't think you are reading the Nebraska Test information. It says calcium chloride solution not just calcium chloride.

 

[Darby Creek]

My 9n has 32 inch tires,so i guess the old girl is rare,but i think i'll let her go before she needs new shoes.

 

[Bruce (VA)]

OK, fine. You do the math then.

How much does a gallon of water weigh?

How many gallons are in each tire?

How much does the salt weigh?

Add it up, see what you get & have the courtesy to post back.

There isn't any math to do other than to multiply 151 lbs time two. The Nebraska Test specified how much weight was in each tire.

I'm beginning to suspect I know why you never made it any higher than Col. If your interpretation were correct the weight listed wouldn't be right - that's why you asked the question intially. Obviously the tractor itself doesn't make the weight without something else being added. So either the weight given is wrong or your interpretation is incorrect. You have been given a very reasonable explanation of how to get to the weight listed from the 151# number. If you won't accept that then the weight listed must be wrong - rather doubtful.

[Bruce (VA)]

You can't be serious.

The water alone weighs close to 300 lbs per tire with no salt in it. What is so difficult about this?

I looked back thru, I don't see gal per tire.
(that don't mean it ain't there)

Water weighs 8.345404 LB a gal.

That would be saying that the tires hold 37.5 gal of water, ea.

Got me...

 

[souNdguy]

the early ones on 32" rubber are a bit more rare.

[Retcol]

I thought the Nebraska Test specifications were also accurate and the test for the 9N specified how much ballast was in each rear tire. I also accept the fact there was an allowance for operator/driver. Therefore, I don't know why so many "posters" want to give lessons on how to calculate ballast in tires when that information is already documented. Furthermore, I was trying to figure out if I could haul a Ford 2N and 8N on my trailer which weighs 5500 lbs empty and still stay within my license limit.

 

[NovaNewfie]

Retcol, if there was 151 lbs of calcium chloride "solution" in each tire as you suggest that would mean there is only 8-10 gallons of water in each tire. Instead of arguing with the good advice and logical answers you've been given can you explain to us why they would only fill the tires 1/3rd full.

 

[NovaNewfie]

Since you didn't tell us what your towing the trailer with or what your license limit is the best advice I could give you would be to put a tractor on your trailer and tow it to the local scale house and have it weighed.

 

[Retcol]

There isn't a local scale house. Therefore I wanted to just estimate as close as possible the weight of the tractors.

 

[Retcol]

I was only reporting what I read in the official Nebraska Test. I don't know why nor does any one else know why the tires were only 1/3 filled.

 

[Anonymous-0]

Just talked with a fellow who planned to trailer his 9N He got 2560 lb.

 

[Retcol]

Thank you very much for the information. I should be able to load both the 2N and the 8N on the trailer and stay within my license.
