Deere manual quesiton regarding tire settings

[vtsnowedin]

Here is a page from the online manual for the 6330. the note at top left is what I was looking for.
Permissible Front Axle Load in Relation to Tires (Operation with Front Loader)
The values quoted here apply only for travel speeds up to 8 km/h (5 mph). Max. permissible front tread width with front loader is 1.80 m (71 in.).
On leaving the factory, tractors may be equipped with the following tires:

Not the same as having pictures of YOUR new tractor sitting in your yard with a family member smiling in the seat. We like to see the options you picked out and how it all came together.

A lot of options aren't very photogenic.

A lot of options aren't very photogenic.

That's true but that doesn't seem to stop anybody. Just the thread of 'pictures of your snow removal tools' runs to 167 pages.

For my JD 6415 the maximum recommended setting for the front wheel tread is also 71" for a loader
Wheel Position 7 = 70.2". Position 8 = 71.3" I used position 8. I figured .3" will not hurt

I need to check where the rear wheels are set.I think they are at position 5 I tried to set them so the overall width (not center to center) matched the front overall width. I wanted them like that so if the front tires would go thru an opening the rears would too. I know wider would be more stable, but I do not have steep areas that are a problem.

That was my point for stating earlier that wheel tread shouldn't be set to maximum. This is especially true with tractors equipped with frt end loaders.

[hotchkiss]

I went with position 7 on the front and the back. On the front that is an inch less than max and on the back I end up with 91 inches outside to outside so and 8 foot mower or tiller will still cover the tracks.

[Tx Jim]

Geez I wish I had an 8 ft tiller instead of the 6 ft model. What brand is the 8 ? Some people have all the luck.

[vtsnowedin]

I went one further. Position eight on the rears plus four inch spacers. Very stable and plenty of chain clearence.

[Tx Jim]

I understand that wider wheel tread gives more stability but in turn it also gives more stress on tractor components such as axle brgs. What's your need for such a wide tire spacing? Surely not for just tire chain clearance? What's the frt tire wheel tread spacing?

The front tire position is the recommended 71 inches. The need for the extra width in the rear is the amount of steep land I have in both fields and woods. The width greatly increases the amount of land I can reach safely. The extra four inches does increase the stress on the hub bearings a bit not not as much as many believe. The rimguard in the rears is of course supported directly by the ground so doesn't add to the equation. Ballast boxes on the 3PH do add to the bearing load and it is when doing loader work with a full ballast box on rear that bearing stress might be excessive. At all other times with no rear ballast on I think I'm well under max stress.
