Steve Person, welcome to WFM! I think you'll like it here. John Lang, i kinda like you're blue/white cubby. Looks like a 102/122/123? Can you tell us a little more about it?
I agree with Roger (even though I DO have 10 inch rims on the front of one of my 322 tractors with 5 lug wheels...the tires are only 18 inches in outside diameter.) A 21 inch front wheel would really impact the 'level' of your tractor with even 26 inch rear tires.
You can get 10 inch steel rims in both 4 and 5 lug versions, but either would require modifying the front spindles to accept them. I put 5 lug hubs on a 317 once, so there is a thread in the archives you might review. http://www.wfmachines.com/discus/messages/335/393172.html
has any one ever put duals on a 317 can they handle the extra load without overloading the rear axle i just was wondering if the extra traction and less compaction would be worth it have one set of tires with fluid and chains the outside set would not have fluid or chains but would have wheel weight hanging on them 50 lbs each gonna use to push 54" blade thanks
Patrick duals are for floatation not traction. This is so the tractors weight is spread over a larger footprint and the soil is compacted less. You will in fact get less traction than with single ag tires for example. They look cool but for a lawn tractor have no practical use for lawn tractors unless you have very soft/muddy soil conditions. Roger
Did JD ever make these or is this custom built? I saw it years ago at Charles City,Iowa Power show,the owner was never around that I could ask about it.
ROGER H. - I respectfully disagree with your comment about having less traction with duals than single tires. I guess it could depend on surface conditions but in my experience pulling the same implement with and without duals you will have considerably less slippage(more traction) with just the addition of duals and no other added weight.
As you said, compaction is reduced, you're not trying to climb out of ruts constantly with your drive tires. You actually gain a few percent added travel speed for any given speed because of the reduced slippage.
I do agree that adding duals to a l&g tractor for pushing snow, dirt, rock, etc with a frt blade would be counter-productive. Single tires & chains or added weights would be the best way to increase traction.
We mounted a set of duals on a 214 a couple of years ago. Just for kicks and grins, we used the same tractor to pull a lawn roller before that with turf tires, so we decided to hook it on with duals. We sat there with the tractor digging 4 big ruts...it would not move it! It's a big lawn roller, but we've never had the problem before without the duals on it.
I think its time to remount the duals again. Thanks for bringing it up!
Im trying to put a 42 blade on my 67 112 and i cant get it just right. I dont where the lift rod and helper spring hook on under the tractor and some give me some help on this or maybe pics of one with it on them so i can figure this out.
The problem with duals (and yes you WILL get more traction, that post is just nonsense saying you dont) and a 54" blade, Your outside tires are going to stick out farther than your blade and it will compact the snow you need to plow on your next pass, It also will prevent you from getting up close to a house or garage while plowing as the tires stick out...
If the search option isn't your friend, Go to the Round fender section and press Control+F keys at the same time and type in "helper" in that find box. Once you learn to navigate, you will have more fun with this site.
The discussion about duals is interesting because everyone is at least partly right...
Doubling the contact patch of rubber to ground without substantially increasing the overall weight will definitely reduce the contact pressure at the tire's footprint. For any tire with a tread pattern, but particularly for lug/bar tires, the reduced pressure delivers less "cogging" so the traction is really limited to the coefficient of friction times the weight of the tractor on that axle, distributed over the sum of all the footprints of the tires.
It certainly is conceivable that the "working traction" would be higher with a single set of lugged tires versus duals in the same tread pattern for certain loose surfaces like soil or snow.
For conditions where cogging is more of a factor, like mud, the duals might give better working traction. Remember that wheel-driven dragsters can achieve accelerations higher than the theoretical limits imposed by a unity coefficient of friction by this type of cogging (essentially they melt the tire compound into the pavement, and the torque achieved will severely distort the tire sidewall -- perhaps you have seen pictures of this happening.)
To comment on the duals situation I have duals on a 318 jd and a super cc (slightly longer than a normal cub) that I pull a 6" landleveler and 50" disc and can honsetly say that I have tryed it both ways and they will not pull them without duals. Both of these tractors have loaded 26x12x12's
hey guys, i have a 420 and can get a model 50 snowblower in like new shape off of a 400...will it fit???it looks like the bottom mount on the blower is wider than the 420 attachpoint but the top looks fine...i was wondering if i were to "extend" the pins on the bottom and maybe make a bar all the way across.. would that work...just wondering if that would work or if everything like the driveshaft mount and things like that are different...thanks for the help!!!
Yes, LOADED tires will make quite a difference when you use them as duals, since you are adding a lot of weight to the axle in question. You are increasing the area of the footprint(flotation) but also increasing the down-force (weight) at the same time so you do get more working traction in almost every type of surface condition.
Stephen asked "JRL, you mentioned a Haban tag-along mower. do you have a picture of that anywhere"

Here is info on the Haban and more photos of the cc123. These are in my WFM gallery photos.
Anyone else having problems with the jd primary drive belts this year? I keep burning them up. I see these new jd belts are made in China...
Here's what happens to mine after about 1 or 2 months use.
