In a tractor power take-off system in which first and second PTO shafts are disposed in the transmission case, the transmission case has at the bottom wall thereof an opening for taking off power to the second PTO shaft and there is disposed a PTO gear speed-change mechanism commonly used for both the first and second PTO shafts. The PTO gear speed-change mechanism has a PTO speed-change shift gear meshed all the times with a large-width speed-change gear for transmitting power to the second PTO shaft. |
