YM195 was the 'Americanized' version of YM1700. YM240 was the Americanized version of the next larger tractor, YM2000. These latter two differ from YM1700 only by, basically, a few mm larger cylinder sleeves, a water pump added, and larger tires specified. So a YM195 manual published by Yanmar-USA is a near-perfect match for your YM1700. (and its written in native English). A YM240 manual is a very close match to your tractor, the difference of water pump/no water pump and tire size etc shouldn't be a problem.
