New to this forum. I joined because I recently purchased a brand new 3039R tractor. So far I'm very pleased with the tractor other then the wheel base is it little narrow. I was considering adding wheel spacers to the rear wheels but when contacting my dealer found out they are not offered for this model and adding them could void the warranty on any thing damaged as a result of the wheel spacers. After doing a bunch of research on line I plan to add the 3" wheel spacers anyway.
In my searching for information on wheel spacers I learned that my 3R tractor along with many other comparable CUT's have cast aluminum rear axle housing and transmission housings? Can anyone explain why aluminum is chosen for this application versus cast iron or steel? At the cost of these tractors I can't believe its to save money. I'm just curious to know if there is a good technical reason for using aluminum. I also wonder if that's why John Deere does not approve the use of wheel spacers on my 3030R.
I appreciate any input
