    Posted: Yesterday at 7:43am
This information appears to be unobtainium - does anyone have specs on the pitman arm for a no. 5 sickle bar mower? I really just need to know overall length. I’m looking to make one out of some pallet scraps while I refurbish this mower back to working condition. Thanks all!

 The standard wooden pitman arm for an Allis Chalmers No. 5 sickle bar mower is 
26 inches long. The correct part is also compatible with the Allis Chalmers No. 3, No. 4, and B/C sickle mowers manufactured in April 1949 and later.

When buying a replacement pitman, you can use either the original AC part number 802093 or an aftermarket equivalent

There are 2 different pitman sticks used on the #3, #4, #5 and the B/C mower.

  Which on you need is determined by the type knife connection you have. Clamp on or spring loaded.

 You can figure out the length needed by yourself: Move knifer to either inward or outward position with a section centered on a guard, Position the crank arm in the matching position and measure what is needed between the straps at each end. 
If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Well... see here's my problem. The mower is currently stuck in place due to sediment and corrosion from sitting in the dirt for years, so theres really no way, at the moment, to move the knives. The old Pitman rotted off due to this.

There is a spring on the cutter bar, just inside where the pitman would be. I'd assume that means spring loaded. 

I guess all things considered I'm not completely concerned about an exact measurement, but a ballpark number while I get the cutters free is fine. Then I can update back here with some data when I get it all sorted out.
