Live PTO, semi independant, transmission driven PTO are different- the transmission driven PTO is older, no longer commonly used type that meant main clutch pushed meant power from engine to transmission stopped and so did PTO that was driven off transmission gear/shaft. Any body that mowed hay with a IHC H probably knows about backing up 1-3 feet after a jam to continue cutting hay without another immediate jam since PTO didn"t start until clutch engaged and tractor started moving a bit- you needed a little time to get sickle blade up to speed. The 60 John Deeres had seperate drive off engine for PTO- handy on mounted picker as could stop with hand clutch, leave in gear and let elevator run at end of row to fill wagon before turning- didn't have to full stop, shift to neutral, let out clutch to clear elevator, shift back into gear and then make turn like on IHC M. Semi independant transmission driven like on some ACs- Uncle WD45 had transmission driven PTO but a extra hand clutch just for the use of PTO when stopping- come to end row with picker, pull hand clutch and axle clutch pack disengaged, tractor stopped but tranny gear drive to PTO kept going. Some of AC tranny drives worked in reverse also- jam chopper or baler- stop and put tranny in reverse and back up 3 foot with PTO engaged and jam cleared. IHC live PTO on 350D drives off outside of flywheel, seperate drive from tranny and seperate engagement lever- very handy for mowing and baling, replaces H and M quite well. French and canadian MF had some models with the double PTO possible, reverse use possible setups so they could run older and newer equipment- good sales idea and usefull on some equipment. PTO speed early were about 540 RPM nominal- give 20 RPM variance- at rated engine speed - varied depending on tractor from 900-2000 RPM engine speed. Newer , higher power- over 60/75 HP- PTO is a 1000 rpm standard at whatever engine speed- some tractors have dual speed or quick swap PTO shafts for use on different equipment- the splined shaft standards differ- old was 1 1/8, 1 3/8 inch shaft for 540 and 6 or 7 slines, new shafts have more splines and I haven't used them but sisters 88xx something BIG JD has it- 12/20 slines maybe? Means the old equipment doesn"t get torn up running double designed speed since shafts won't fit. Hope this doesn't confuse you some more- but stick around, might learn some more interesting things RN..

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
