ISO Mounts
 

I seen a lot of discussion on this forum about the use of ISO vs solid mounts and have a question.

I recently purchased a 1976 Ford LGT 165 garden tractor (made by Jacobsen). This tactor uses 2" OD x 3/16" wall steel tube for a frame. The engine is a Kohler K341AS that has the oil pan welded to the the frame (not a modification, this is the design used by Jacobsen for all the tractors built by them at the time). A true solid mounted engine.

This is a very smooth running tractor with very little vibration. As a matter of fact, it has less vibration than any WF or QL Cub that I've ever experienced.

So, here's the question:
What makes this tractor so vibration free?
Is it the frame construction?
Is it the method of engine mounting (welded vs bolted)?

Just curious about what you might think

Here is a Parts Breakdown of the Ford LGT165. It does NOT show the motor oil pan welded to the frame.

Thus, this was a modification done by a previous owner.

With regards to the issues ISO Mount vs Solid Mount. People who prefer the solid mounts are usually "pullers" or people that don't mind the vibration.

Seems this question was asked yesterday. Don't know why we are re-visiting this issue again.

I thought I just replied to the same thread a couple days ago...:confused2.gif"

I don't recall the model number or engine size, but a friend years ago had a Ford garden tractor, and the engine oil pan was indeed welded into the frame, it was designed that way, the oil pan was an made into the frame, not PO mod. It too had a round tube frame, and the oil pan was factory installed between the frame rails.

I just found a reference to a welded pan on a Ford forum. It didn't say what models but sounds like it truly is a oem setup.

That's a pretty broad question that could take pages to answer. But in short, they use Kohler K singles mostly, then Kohler twins in the larger, like the 195. Some are tube frames with oil pans of the engines welded in, then others std style frames with bolt in engines. Hydro's were all Eaton that I'm familiar with. Not sure on the std transaxle make. Rear end for the hydro units were Peerless 2600 series. Options included rear pto, 3pt rear lift, and of course front pto to run decks or snow blowers & such. Specs are too far reaching to post all. Anything in particular? Someone else may have to help you further. Never owned a Ford myself. "

I did another google search and eventually found that, too.

OEM or not...that's just plain stupid for a multitude of reasons.
