Rear tire width?

[RhallVA]

My new B2410 has Bar Turf tires in the back and the axle looks as if the tires could be moved two "settings" wider than they are now. Is there a general rule as to how wide they should be? (The instructions with my Tiltmeter say they should be set as wide as possible). My major use will be mowing with the MMM, but I have a FEL and rear blade that get some use as well. Where should mine be set?
How difficult is it to widen them?
Thanks!

If you have sloped terrain, I'd set them as wide as possible. The only reason to set them narrower is if they prevent effective use of an implement, but I'd set them wide then narrow them back up only if necessary.

To adjust, there is a pinch bolt that has to be losened, and a through bolt that needs to be removed. Jack up the back fo the tractor enough to take off the weight, then work the wheel out until you reach the widest setting where there is another hole lined up with the through-hole bolt. Put the through-hole bolt back in and tighten up the pinch bolt, and go do the next wheel.

Keep in mind that the rear wheels are heavy, especially if they are filled, so "working out the wheel" may be easier said than done.

Hi Roy,

I was actually looking at the Kubota manual for my 60" MMM for my B2410 last night! I presume that is the same mower that you have?? I noticed that it specifically stated to mount the tractors rear wheels in the widest position. It even had a diagram of the axle/hub setup and pointed to the outer-most pin placement. I would think it may be necessary to ensure that the MMM doesn't rub the tires when it is raised to its highest point.

I widened the tires to their furthest out position on my B7500. My R4 tires rubbed on the rear left wheel of my 60"mmm when it was in the full up position....Bummer! I do have one more hole outboard but got the impression from the manual that the axle shaft shouldn't be in any more than flush with the hub. The manual seemed somewhat vague on this point.

I have a B2400 with the R4 tires. I have found the widest wheel spacing to be quite valuable. I recommend it highly; especially if you are working on hillsides.

If you are doing any FEL work that involves digging I also recommend filling the tires. That makes a world of a difference!

Well, my tires look as if they could go two "holes" wider than they are now. My rear tires are filled due to the FEL. Is widening the wheels ever a bad idea? Is there a good reason not to move them out?

Also, with them being fluid filled, and looking pretty heavy,
is it possible (wise?) to try to move them myself or is this a job that should be done at the dealership?

Thanks!

It's not a big deal to do it yourself if you've got a floor jack. I did one side at a time and lifted it as little as possible off the ground. Then I rolled it away and made sure it didn't fall over while moving the hub. The worst part is getting the holes to line up but I wouldn't say it's so tough that I'd consider taking it to the dealer.

I agree with Jeff. IMHO, Moving the tires wider is really easy. Just jack up the rear, loosen the retaining/pinch bolt, remove the locating pin, slide the wheel along the axle to the new location and refasten everything. The hardest part is fighting the weight of the tire. Even that's not so bad.

I actually removed my tires to move the hubs out. Now you are making me wonder if I had to do that or not. I do know that all of the axle holes don't go through from the same direction but can't for the life of me remember which one that is. Oh well, as with many things I do for the first time it is seldom done the easiest way./w3tcompact/icons/smile.gif

The 2410 must be different from the B7500 - the locating holes are not on the same surface of the hexagonal (octagonal?) axle. I have to remove the wheel completely, rotate it slightly and replace it. When I get my tires filled, I think I'll be rigging something up to suspend them from the ceiling should I ever need to change the width.
(I started a sentence with "when" - so shoot me.)
