Does anyone have a belt diagram for a John Deere 68 riding mower? And what size belt is that? Thanks.

Hi,
I have a website dedicated to finding such pictures. Those old rear engine riders have been a pain more than the Piranha deck.
I attach the parts picture from Deere parts.
Peace,
Clarke

What size is the belts used for this lawn mower?

Hi,
The motion(traction) drive belt is a M44483(said to be 1/2" X 48.4".) The mower drive belt is an M44498(said to be 1/2" X 60".) The first numbers are Deere part numbers. The parenthetical numbers are from a cross reference and if used a high quality Kevlar or Aramid-sheathed belt should be used.
Peace,
