Theory for the engine experts
 

Was at a garden tractor show last weekend and there was two guys there with Oliver tractors. I was looking them over(tractors not the guys) and noticed that the oil pan was welded to the frame. I pretty sure Jacobsen made them for Oliver/White. The claim by the two fellas was that the engine lasted twice as long being solid mounted to the frame
What do you guys think?

Yes, the tractors were built by Jacobson.

Those guys are nuts.

The Olivers are/were definitely made by Jacobsen. The Olivers I saw were identical to my Jacobsen GT 10. The engine on mine is welded to the frame but is a Kohler K241.

So, they are welded from the factory?

Maybe I never paid that much attention when looking at them...:bigthink:

Yes Jon, welded right to the frame, :beerchug:

Dang. Never noticed that when looking at them before. It must be a steel pan then.... :bigthink:

If that is the way it is made, then I guess it's fine. I wouldn't go welding one to a Cub though.

I did not know this.
Anyone have pictures? having trouble trying to visualize how it is welded to the frame :HeadScratch:

I'm guessing they did that to stiffen the frame or serve as a crossmember?:bigthink:

If I remember correctly Jacobsen made Lawn Tractors for Ford also... I worked on a few in the past but don't remember them being welded..:bigthink:

Ford LGT tractors had the engine oil pan as a permanent part of the frame. I bought one without an engine and I remember when I mounted another K series on the frame, I had to take the oil pan off the replacement engine and bolt it to the pan that was part of the frame. My guess, the design was for structural strength. Those were very stout built tractors.

Here is a picture of at least one version of the welded pan, post 419.

Thanks for the pics and the info Mike...

After seeing it I remember the tubular frame... Looks to be a very stout design!!:beerchug:
