Re: (ET) Haban Sickle mower speed question.

[Dean Stuckmann <dstuckmann icloud com>]

I believe that there are two strokes per revolution. One left and one 
right. I had the same question a while back and did some digging on the 
specs for an old Case mower we had on the farm with a 540 PTO. The numbers 
supported the two stokes per rev.
