What are some things people have been doing to lighten up their G's. Both styled and un-styled.

How about like a light weight front end for a G? Maybe a wide front... there is a lot of weight out there with the steering post, and rolla-matic.

ALSO

What about taking out the fan shaft, pto shaft, unstyled seat on a styled, removing all hydrolics, pressed rims, smaller fuel tank... any more I can do?

I can run three international 100 pounders on my 38, but am building a new tractor. Just looking at options. Thanks for the reply.

I dont know how much you want to gut this thing, but here are some ideas.....
Remove fanshaft, ditch heavy radiator w/ cast tanks for little one w/ plastic tanks (only works on a styled tractor, doesnt really look good on an unstyled), get rid of main fuel tank and use the one gallon gasoline tank, get rid of rear cover and make one out of sheet metal one that weighs 6lbs, seat mount made w/ conduit, steering shaft made w/ conduit, little steering wheel, weld .500" plates on for hubs as close to axle housing as you can get them and cut off axle accordingly, make pressed steel wheels using 16ga. sheetmetal between beads. If you are real good welding the wheels up, you can go tubeless rear tires. It's a lot of work, but the pto bevel gears in the bottom of the transmission are worth about 20 lbs. You could also get a lightweight reduction gear starter. The brakes can be lightened by 15 lbs by cutting unneeded material out of certain places. Chrome moly tubing can be used for hollow axles.

As far as a frame, bolting a pressed steel A frame on wont really work..... .they made the G frame wider around the engine block for a reason; but you can take a torch and remove some material from the inside.

The wide front will get you about 50lbs or so, depending on how you make it. On our A, the cast front pedistal w/ light hubs weighed a little over 200, and the wide front we built weighed about 150. We used a steering gear off a Ford Falcon and made linkages to make it all work.

Hopefully the picture will give you a few ideas for a widefront end, etc.

It's actually an A, but the same dieting techniques apply. Here is a pic w/ sheet metal on it.

Yea.. I noticed the straight side frames.. I have seen pics of your tractor at different events... and I like the V-cuts much better than the F&R's... Almost painted mine black.. but chickened out.. haha.. And I'm sure your A has a lot more in it than my G... I'll send you a pic... JDGnut

Why not take the styled G, and turn it into an unstyled? I belive you could remove the fan shaft assembly, not for sure if anything in the governor would be affected or not. You could try to find a flatback cover for the rear end plate, but the cover may be tough to find. Would not take much to build a light front end, a rack and pinion steering assembly, It also depends on rules, and what you can get away with, now if it is an all out open class situation then the sky is the limit, of course,, so would the $$$$ in design. Maybe make the steering post, clutch lever, and anything you could replace with maybe aluminum,, or parts from a different model JD that would bolt on, and be lighter. Pressed steel wheels, just make a set of hubs, or weld on hubs,, What about making the channel front frame out of steel, replacing the cast tub?? then bolt on an A front end to it, then you could run the A radiator, steering would not be difficult to route. Sheet metal might work too with a little fabrication. G's are so heavy in the rear, light in the front, eliminate anything you dont need, make steel, or aluminum plates to cover the removed parts, Move the battery out front, get a small fuel tank, mount it on the front too, Possibilites are endless. Just be realistic on your goals,, ChadS

That A is wicked looking! Thanks for the help.

I was at the Tomah Grand National this weekend and took some pictures of the tube front ends they use on the Pro-Stocks; I think that could be done.

Anybody got anything to say about cranks, breaks.... billit or not?

Yeah I want to know can you just slide the PTO shaft out? If you do that will that stub shaft cause problems? If you can't slide it out you have to remove the back cover right? IF any knows the answer to this question i would apprecite it! Thanks email me at [email protected] if you know!
