John Deere B weight

B

How light can I get a late styled B with 9 bolt steel wheels and 13.6 - 38 tires and a 250 lb driver ? Don't wanna go nuts with aluminum this and that. Would flatbacking it with a factory cover get me in 3500? Looking to stay stock classes so it has to at least look factory.
 

As delivered "NEW", it weighed 4,400 lb...

With you on it it will be close to 4,650 lb..

All you need to loose is 1,150 lb (approx) and have all the field dirt cleaned off..

Maybe filling the tires with Helium would help....you have the right Idea, loosing rear weight...the front end is fairly light in the 1st place..

Most "Serious Pullers" have junked the original Cast iron Radiator and installed one out of an old junk foreign car, with electric fan.. move the Battery forward if you are allowed (in front of the front wheels is better)..
Take the "Roll-a-Matic" off the front and only use one front wheel....!!

On my 1984 b. The 4000#class is best your going to do maybe 3750# class if you have one. I made my own flat back cover. Press steel 13.6 tires and aluminum weight brackets
 
We have a styled G that pulls in the 4250 class.There are B's pulling in the 3000 lb. classes.
 
I agree with you, Ron, on everything, but I believe the weight you quoted was for the standard cast center wheels. Probably take off about 350-400 lb if running stamped steel like his. Like someone said, stay in the 4000 and 4500 class or maybe 5000 with weights and creeper gear. This way you stay away from most of the hopped up little Allis that usually run away with the 3000-3700 classes.Stik with dead weight pulls or low speed limit pulls where creeper gear and driving ability trumps HP and the speed it takes to use it. Are you pulling dead weight or transfer sled? And is that all you do with it is pull? You can save at least 20 lb on coolant as you will never heat up ALL the coolant these thing hold by just pulling. You don't need all that trans gear lube either, probably save another 25 lb. You don't need the generator just keep the bat. full before pull day. 1/4 tank of fuel. One can really let it get out of control if you expect to beat the others who have no limits and use tractor for nothing but pulling.
 
We have 40 B styled in the 3000 lb class with a 175lb driver 4.00x15 tires on the front 11.4x 38 rear, flat back cover no PTO, can't have over 4 gallons of gas on some scales. The late B would be heavier.
 
A well respected old time puller told me that he has weighed at least 6 sets of cast centers after removal and all have been 347 to 352 lbs each. Almost 700lbs per set. Sled pulling in a field ready class. So everything must be a factory part including the drawbar except for weights and brackets
 
I have a late 1948 styled B we were able to get down to the 3500 pound class and it does quite well. We did the usual ie; pressed wheels, flat back with pto we fabricated brackets with angle iron to fit the seat but we also found out if we took the front pedestal off from a 39 or a 40 John Deere B with a little effort it will fit and you will save about 75 lbs. Put smaller wheels up front and if possible cut some holes in your pressed wheels if allowed. Alter you draw bar and you can save some more weight if you are running a mag then you can also take your battery out and take the starter out from underneath, which means you'll either have to pull start, park it on a hill or turn the fly wheel. Good Luck!
 
Can't alter the drawbar or the wheels. Must be factory parts on the outside at least. Haha I'm assuming the 39-40 front ends are not roll a matics? Anybody know what the weight difference between roll a matic and regular fixed 2 wheel front end is? What about factory single front wheel?
 
51 B,Pressed steel-13.6-6Ply tires,weight Bkts(F&R),ROM front,original everything,160-190 driver.Maybe 50-100#weight(depending on scales)4000#any day of week.
 
Friend of mine has a '40 B and he has to add weight to get to 3500 lb class. He has a flat back, pressed steel on back, and no electric start. No other mods.
 
..then you must weigh back in the weight of the steel centers, so net gain will not be the total of the cast centers.
