Hey All. I just purchased a 1968 John Deere 112 with the 10HP Tecumseh engine and manual lift. ID tag below steering column reads as follows: Type T0650 Serial#115083M. Engine tag reads as follows: Model#HH100-115093B Serial#888 08563. Purchased with the model E0670 46" mower deck and model #36 snow blower. Seems complete but for the starter motor and battery. PO had a pulley attached to the end of the crank and claimed it would pull start when last parked.
My intentions for this tractor: Total restoration from stem to stern though this will be a "resto-mod" as I intend to convert is to propane so that my wife can operate it (severe respiratory reaction to petroleum/carbon monoxide fumes). We intend to use this tractor on our 10 acres. Any modifications from the original design will be made with reliability/longevity in mind. I realize that these tractors are collectible but it will not sit much is the shop. We plan on using it as originally intended.
I understand that the Tecumseh engine for this year/model may have parts available but that the ignition system on this particular model is failure prone (decal reads SOLID STATE). I read somewhere that a points style ignition conversion is possible to address the reliability issue. I have the advantage of an extensive series of factory service manuals for Tecumseh small engines of this era that I bought from a professional small engine mechanic.
All this being said I have a couple of questions: Should I make the effort to work with the Tecumseh engine (PO stated that it had a knock when last ran) or replace it with a Kohler? If replacement is advisable I wish to make as few modifications as possible so do the 112s with the alternate Kohler engine have parts I can purchase to make this a bolt-in swap?
Any advice is much appreciated. Thanks is advance!
