Just bought a 1722 from Ohio fella. Got several manuals with it. I found the date stamps, but don't know how to read them. Where's those instructions? On here? Here's what I have so far.

Frame stamp 17223E10601 I'm assuming the E might be a year?? Have seen that info on older charts, but they seem to be for S models, so may not apply??

On a tag next to this stamp was SPEEDEX 7670 Never saw separate tag before, what is this?

How to upload a picture? Can do in this part or elsewhere?

OK, back again, with Another new tractor! Same issue. Seems I might have a 1632, but not with hydro brakes. Here's tags

On plate 8182

Stamped frame 324A 631

Again assuming A might be year. 32 part of 1632? Not sure of the 4 after. Rest serial?
