My brother has a good pair of 26x12x12 turfs off of his 420. he put trencher tires on a few yrs ago and say's he will never put the turfs back on. He said if I wanted them to come get them for my 318. on my hill a couple inches extra width would help
My only concern is clearing the mower which I think they will.
Has anyone put the 26" wheels on a 318?

You'll gain a bit more ground speed too, about 9" +/- per revolution of the tire. If my calculations are correct, what was 10 MPH will be about 11.25 MPH. Not much, but in tough grass, could load the deck up. On a hydro, wouldn't be a problem!

JD, I'm not sure those will fit on the stock rims. They may be too wide. If you do this consider up sizing your fronts as well. This will level the tractor and give it a nicer look and also make deck alignment easier. I've seen a 314 on here that had larger tires all round and it really looked great.

Put the 26X12-12s on the JD140 and they did hit the rear adjustment wheels on the mower deck when in the raised position so I went back to the 23X10.50-12s.

Will be putting the 26s on the T105 Copar Panzer.

Can't help you at all as far as whether those tires will fit but aren't the rear rims on the 318 reverable to change the tread width ? I use mine on a pretty steep bank , "you need to feather the uphill brake to keep the tire from spinning " If you put a taller tire in might raise the center of gravity and loose what you gained on tread width , just a thought , Al

Brian these are mounted on the stock 420 rims, brother had a spare set of rims he mounted the trencher tires on. So it would be a simple bolt on mod.
Al, I only had one bank that sent the pucker factor into the stratosphere. The tractor would slide on the bank going parralell I had to run with the fronts almost to the lock and as you say use the uphill brake.And the part where I had to go around and down it the rear wheels slid.
But the Good Lord is looking out for me. Birdfoot Trefoil came up voluntarily in that section. Who was I to argue with a nice ground cover, I have let it grow and quit mowing that section. Funny 20 yrs ago I would never given it a second thought and I don't find it as easy to ride the uphill fender as I did? 7 yrs ago when my heart got out of whack, I came face to face with my mortality and just don't take the chances I once did.

As for the front tires, one has a tube in it and the other needs one. When I replace them I would go with the taller ones.

Tinker: I think I will try it and see if I have the clearance. Right now I'm running chains year round.
They work well, except when I'm on the asphalt drive they ride a little rough.

The chains are another consideration. if you want to use them on the larger tires you might not have the clearance.

Only one way to figure this all out! Mount them big suckers on there and see what happens! Best of luck!

Someone here put 26's on a 314 and they fit so I think the 318 should be OK. The chains are another matter. It aint pretty if they hang up on the underside of the tractor somewhere.

Yes I considered that, I may just keep the stock tires with chains installed to mount in winter when I have the snow blower on.
Or the Chains will also fit my Murray Yard King if needed, so they are not a loss.

It is always nice to have 2 sets of tires available. The wider stance may not be a good thing if you use a snowblower. It could make the tractors rear wider than the blower.

My experience is that the 10 1/2 inch stock 420/430 rims will not clear the mower deck.They can only be mounted in the wide position because in the narrow they hit the brake and lift linkage.
But since it is your brother and not a private seller then why not try anyway,If they don't work give them back.
Atteched is a 318 with 26 inch tires but on 445/455 9 1/2 inch rims.
Other picture is from a 332 with the same rims but different 26 inch tires.
My experience is the 445/455 9 1/2 rims is the best choice with a mower deck.
I have them on my 322 currently but have not mounted the deck yet.
Should fit as the other machines were mine in the past so experience is up close.
Good luck either way.If they fit make sure to show us some pictures.

Thanks for the welcome Brian.
I actually don't own either tractor anymore.
I went through a phase of buying,selling,trading for a few years there.
Have settled down to the 430 and 322 but went through several for a while there.
Glad to be here.

AJ
