JD730 diesel diet

Im looking at trying to drop a little more weight on my 730D for pulling but have to keep it looking fairly sociable. I have already done a fair amount of work on other locations on the tractor and now am currently looking into the steering. I already have the factory 730 non power steering system and fanshaft but actually gained 15 lbs from the factory power steering I removed. I have heard that the 70 manual steering sector is much lighter than the 730 one and am wondering how much work it would be to make it work under the hood of the 730 and if its even possible. If anybody has tried or done this please let me know, any input would be greatly appreciated. Thanks.
 
I don"t have an answer for u as keeping it looking stock but making it light isn"t in my nature I either make my puller a puller or restore to original.. Curious what your 730 weighs? I took ours to a few pulls its 730 diesel with pony start 3pt wide frot 15.5 firestones half loaded and it weighed 9400lbs.. Are u running a flatback? Pressed rims ? A lot of guys have fabbed up front ends of an mt or other smaller tractor that is much lighter. Are u running a heavy rollamatic?
 
I've got a 730chance diesel and the lightest i can get her down to 7500lbs with all brackets on but no weight added i run 18.4/38 Firestone field and roads with 40% tread pressed steal rims 3pt pto and the cast air cleaner housing is all removed it also does not have power steering on it also i have chopped the non roll a matic front post to get front end down i run 6.00/12sl front tires im not sure how much else a person could remove to make it ligher other than weld on hubs and chop the axels off i wouldnt mind just a power trol that does not have the rock shaft or pto holes but they are hard to find
 
What weight are you trying to get to? I have a 1960 730 diesel and have had it down to 7500# and had everything off I could get off down to taking the batteries out!! What a waist of time. Stock classes and pulling in 1st gear was out!!!Put weight back on it and she went to town. When we pull it know we pull in 12,500# class with 18.4/38's. Have won a many pull with it.
 
The quickest way to loose weight on a 730 is to take the sheet metal and put it on a G.....


Lightened diesels never pull worth a crap....
 
To start with this tractor is a dedicated puller. I already have the rare factory smooth rear cover with no holes for anything, pto driveline completely removed from rearend housing,all hydraulic components completely removed from the tractor, electric start, light billet steel hubs, light rear steel rims, 18.4-38 Armstrong 6 plys at 40% (about the lightest tire in that size you"ll ever find that actually work), manual steering, MT narrow front with small wheels, oil bath air filter housing completely removed, pony start main fuel tank(cause its smaller than the electric start one), factory fuel filter setup will be replaced with a lighter modern spin on style. I do not pull in a restoration stock class but it still cannot be torched on and welded on to get lighter, all my mods bolt on and still have Deere casting numbers on them, minus the rear hubs and rims. I understand that these tractors do well in heavier classes but most of our antique pulls in this area end at 7000 or 7500 pounds, a rare few go to 8000. So all I can do is make the best of my situation and work with what I have, thank you though for the opinions, they are apriciated. I am still very courious about the 70 steering sector though.
 
While I respect your opinion Factory Farmer,and understand where your coming from, I already watch enough gas G's and gas farmall M's at our local pulls to last me a lifetime. While I know it may not be the best option, to me its better than blindly following the norm. Variety is the spice of life. And please dont take this as hating on gas tractors, I also pull a gas Minni quite often and have for many years.
 
What about removing the heavy cast iron radiator and make one from another tractor work or go to an aluminum radiator i know there not cheap and it would be alot of work fabing it in to work with possibly an electric whater pump of some sort i have heard of people Machineing or cutting off some onthe bull gears im sure its possible to fab up a new lighter front frame depending on ur rules and regulations in ur area on how close to stock appearing on the outside they want it up here in Minnesota they want us to be stock appearing on the outside but what ever u do inside is up to u
 
Im in roughly the same region as you are and our rules are very similar to yours over there. I have thought about the radiator but I would get way too much grief over it, thanks for the ideas though.
 
You can loose 70 pounds or more with turning the bull gears.

Mine run between $600 and $800 depending on how long and how much I take off. A pair for a G would be $600. I'm not sure how much bigger a 730 gear is.

I understand completely, stock gas tractfors are boring as hell to watch. Diesels are always fun to watch pull. Around here nothing is stock so about the only way to compete is with a stroked g, it would take Lot mm ore money to make a diesel run around here.
 
Mw do u maybe have an idea where a person could get a smooth style hyd power trol housing like u have and my other question is would that power trol housing be sufficient enough to reinforce the rear end housing to with stand weighing the tractor down to 10500 or 12500 classes thats the reason why i haven't fabed up a steal one yet because when i weigh it up for the heavy classes im afraid I'll. Crack the rear end housing and i believe the cast power trol housing helps to reinforce the rear end housing what do u think im not considering installing one for the less weight im concidering it so i can get my drawbar in to 18 inches the ordinary live pto and rock shaft style housing is to long
 
I am not sure what it weighs exactly yet, I am still in the building process. I would like to get as much of the weight saving tricks done the first time around rather than going back into it time and time again. If I could make the 6500# class I would be thrilled!
 
I got lucky and a friend of mine actually located the rear cover for me, it's not perfect, the center of it has been welded and repaired from some sort of accidental close encounter, but that did not matter to me. It's factory, holds oil, and was priced right, that's all that matters. I did have a line on another one several months ago in the souther part of the country but they wanted good money for it. I can try to put you in contact with them if you would like. As far as the weight and support issue goes that is a good question. To my knowledge there was never a different spec for maximum ballasted weight for a 730 diesel dependent on the rear housing it came with, so that would lead me to believe that the factory flat back should offer enough support to match what the large rear cover could do. But if you look at it another way, without the three point their probably was'nt any way you could ever put enough stress on the rear axle housing to break it so alot of support from the rear cover probably wasent necessary with no three point hitch installed, if you can follow my line of thought there. You could kill two birds with one stone and put the flat back on and use wheel weights instead of suite case weights, that way the majority of the weight is being carried by just the rims and tires and not being transfered through the chassis of the tractor, just a thought.
 
Yes MW I would be interested if you can help Me find that smooth style Power trol that would be greatly appreciated give me a call after 7pm at 952-738-1281 thanks
