This week I learned about agcopartsbooks.com. First thing to do, search for my tractor and browse every page! In the table of content there is a section Cold Start Disconnect Kit, page 89. WHAT!

Screen Shot 2018-03-15 at 22.20.29.png

The only thing I could think off that would help starting would be to disconnect the transmission and/or rear PTO shaft to remove this load. The PTO shaft is pretty free to rotate. The only hint I have is the note A about item #10 which is said to be a part from the tractor re-used for this kit. Looking in the other pages I found a similar spring in section Frame, Driveshaft, Rear axle and Drawbar, item #35 has the same part number. This kit would remove tension on the transmission belts to disconnect it?

Someone has some information/pictures on this?

Clearly this is fairly uncommon.

The more I think about this feature, I am pretty convinced it is used to remove the tension (compress the spring #10) applied to the belts between the engine output shaft (rear pto at the same time) and the lower shaft for the hydrostatic transmission.

Parts #5 and #8 seem to be free to turn into part #4 and in part #4 there seem to be 2 holes. Extrapolating the location of this, if a shaft would be bolted to #4, go through the bottom of the instrument panel and provide a lever that can be rotated. The operator could easily turn the lever to remove the tension, start the engine then re-apply the tension.

That would be a nice feature for anyone using the tractor as a stationary power source (generator, wood splitter, etc). Removing the tension would remove load for the engine AND would make the tractor completely stationary (added security).

That's interesting,, looks like the 1655/1855 is the cheaper easier one to install.
Probably no longer available.
Have you looked into that?

That is interesting and it confirms my hypothesis!

Could be useful when a tractor is used as a static power source like with a generator, pump or other stuff on a PTO!

I saved the pics to a folder. Might be able to make that info into a PDF!

mac102004 I am wondering, if you have this bulletin, do you happen to also have or have access to a tractor that has this kit installed?

Where did you get all the old bulletins Mac?
Hey Jason,

I've bought quite a few of them over the years, usually find binders full on eBay, most times they will be just ag tractor related but occasionally some GT stuff will be mixed in.
