PTO Access Pin

For all that, she gets a nice roll pin and a sense of security knowing that she's under my care and I have a grinder.

Pull the trunnion already!

Also in that same photo that hitch pin clip needs to be on top of that bracket for operation. Just remove the pin while getting the belts on or off then reinsert pin on top of the bracket.

@Joker72  your bone dry set up , made me do this years ago  , every stage of that  pto lever can be improved , greased washer start  at  side of battery tray , firms up any initial movement thrust , eliminate all  play , the heim joint swap is easy , original threading  3/8 x 16, went right over that  with a 3/8 x 24 DIE NUT , OILTHREADING , heim joint  screws right on , that frame swing mount point  . can also be a spring assist  pull  point to stop  buzzing noise . easy fix .pete

I would never recommend removal of any safety device, but I don't have any very young or very old ( I'm only 82) people operating my machines.

So, I do what I feel is required to make my Wheel Horses more efficient and user friendly.   

When these PTOs are engaged they have a high inward axial load on the small thrust bearing and depending on the belt tension a forward axial load centered on the PTO needle bearing.

When the PTOs are disengaged and locked by the brake they have an outward axial load on the small thrust bearing and a bending type radial load on the needle bearing.    These loads are caused by the brake when the PTO is disengaged which is most of the time for most of my tractors.  

Therefore, I remove the PTO brakes and make a new adjustable U bracket for the hoop/shaft connection that only loads the bearings when the PTO is engaged.

My PTOs probably rotate about 1/2 of the engine RPM when disengaged.    

So I only need to pull the lynch pin to be able to install a belt.

I did the same but used a second hitch pin in 1/8 inch diameter in the hole that the roll pin used.

All back to original and fully understood (trunnion pulled).  Thanks guys.  Snowblower turns great.

@Ed Kennell  noting your  pto . I also disconnected my  related brake pad set up , while going thru, my upgrade years ago , on anything with  rotational drag  , collectively  that bearing  drag  , eats clutches , and  and was just something , i was going to improve, often refer to  my mule drive down belt  easily moving by hand  and also no related frayed belts , from incremental  bearing hang up , that mower deck , spindle belt , with added  flat idler  on back return side , eliminated  that long unsupported  belt bounce . have not had any bearing issues of any kind  , noise/ rough , my pto  spindle still spins , when I turn off the engine , silently . like a repetitive problem  , for track down and elimination  . you can see what  fails , often find other related areas , for me once I start  , just keep going  , my plow frame , was  unrelating  trouble spots , just me and a roller stool , it completely  exposed itself , swings like butter , pete       .
