Bigfoot,
 I believe there are discussions about this in older posts. Do a search for "valves" or "lash" settings in the forums and you may find the answer.

OK I've seen 2 different peeps in old answers on adjusting the valves Eric L posted may 25 2013 that he set them at .004 although never said is that Sae or mm most bolts on Yamaha are metric on feeler gage you have
 .004 on top n bottom is 0.010 mm

then headcase on june 14,2011 posted that both intake and exhaust is 0.0031 - 0.0047 n these settings sound to be  pretty wide so I guess Im going have see if they make a feeler gage this wide  

Ive tried setting valves both  to .004 @ TDC and motor turns over really hard

.08-.12mm both intake and exhaust, per service manual

I got my mower running by splitting the diff between  0.0031 - 0.0047  and setting my valves an had go buy a different gage 1 that has .015in. which is in metric or mm    0.38 mm mower started rite up an I mowed yard after changing the filter an oil

Where did you find service manual for your tractor? I can only find one for a 6800 not 6700

They are the same machine, just a different deck.
