TN95A set up

[hotchkiss]

I just purchased a new 2007 NHTN95A fwd tractor and have been trying to decide how wide to set the tires. We have several tractors, but no new hollands. We mow on slopes that are at least 3 to 1 and perhaps a little steeper. The tractor will widen out to approximately 8 feet in the back. I don't really want to go that wide. From the factory they are set at 67 inches (the minimum in the back). Any thoughts?

I own a 2005 TN65D. This is my 3rd New Holland tractor. If you are going to use it with a loader, leave the wheels where they are. Loader work requires the wheels to be set in for heavy lifting. If you will never have a loader on it, set them out to maximize your stability but not too wide to have problems with clearance in barns, doorways, or row work. Good luck! You have quite a powerful tractor. Ken

My TN75D is still set at factory defaults. If I were mowing step slopes routinelly I would set them as wide as my trailer allowed. Probably not 8 feet though, sounds pretty akward. I wouldn't worry about loader load , that affects the front axle. A simple free body diagram will show that the tractor pivits on the front axle with loader load and the rear axle gets less load (hence the reason we need counterweights).

I think I am going to set them in the 79-84 inch range? Seem reasonable to you???

Depends on if you have a loader. With a loader I set the rears slightly narrower than the bucket, and the fronts at the tractor factory manual recommended width (not the loader manual recommendation). The factory rear minimum width is unnecessarily unstable with hills, but helps with the shipping (TN70/TN75/TN85/TN95 ship from Italy, probably other TNs do too).

1 in 3 is 18*, fairly steep if you are lateral, I'd want more width than the factory minimum. Indeed, I'd go as wide as was practical for whatever it is I was doing so ground hog mounds or other surprises are less of a potential issue.

My tractor was delivered as minimum width, it was much more stable when widened. I was surprised at how much difference relatively few inches made.

Try it, probably on the 79 inch side first. How wide is your mower?

Thanks for the information. My mower is a 6 foot heavy duty woods. I have a loader on it, but can easily take it off when mowing. Also what are your thoughts on the width of the front tires? I don't think there is as much of an adjustment range on those? Is there any need to set them out at all?

does anyone know a link to the factor manual. My tractor has not been delivered yet so I don't have the manual. I want to see what is says with regard to the width of the front tires.

Manuals are a CNH profit center, AFAIK there are none available online although if one were desperate enough, the manuals are available for sale on the CNH site.

The loader manual will want the fronts as wide as possible for stability. For most loaders this will mean a setting exceeding the load rating for the tractor for the front assembly at that width-- which typically means using the widest width in front from the tractor manual that still has a rating equal to or greater than the loader rating (despite being narrower than the loader manual specifies).

For the TN70a I was not sure what the relation of the front and rear tracks ought to be. There is no guidance in the manuals. The rear ought to be set narrower than the bucket width. The front is dictated by the load (you can make it even narrower for some sacrifice in stability). But is there supposed to be some relation of the front and rear tracks? After rummaging around for way too long, the only significant effect anyone really commented on was that for making a lot of tight turns on hard surfaces, there can be accelerated tire wear for some configurations particularly in front. There may be some effect on 4wd turning also. But neither is apparently too significant, as it took a lot of effort to find those out.

In the end, I had the front and rear tracks pretty much in line. Previous tractors I had were already set up, and I never changed them.... so never really thought about the options!

Horse7 is correct. I called New Holland earlier today. I could probably find ***** B. quicker than I could get an answer out of New Holland. They wouldn't even give me a spec. diagram that tells me the options at which the front tires can be set. Other manufacturers have this information on line. I was told that they would contact the dealer for me and try to get the information. Give me a break, do they think that I haven't contacted the dealer? Do they think that I believe them when I am told "we send customers to the dealers because they have more information about those issues". Give me a break! Who built that tractor - dealer or New Holland? I hope that I like my tractor better than my first experience with New Holland.
