Is there a tow disconnect on this machine so that i could pull it without damaging the hydro? It is in a bad spot and needs some engine repairs.

Thanks

I don,t know about the loader version but on the 760 dozers we always just pulled the sprocket bolts and let the sprocket rotate on the final. John Deer just forgot something on those early hydros. Have to be a little careful and not squirm it around too short if you are turning but the sprocket will usually just ride in the track chain.
 
Not familiar with that machine but sounds
like it's hydraulic drive, if not simply
disengage the steering clutches. Do you
have another machine that's got hydraulics,
you can jump hydraulic pressure to it and
drive it up on a trailer etc, often done
with excavators that way
 
No steering clutches in the 755 and the hydrostatic drive is an enclosed unit, only way to drive it is turn the pump and if the unit is bad brakes remain locked.
 
It has been 20 plus years since I worked for a john deere industrial dealer. But if I remember right we would take the cover of the final drives and pull the sun gears to move them dead. I maybe wrong.
 
Well if it is like a 750 dozer what is holding you is the brake . Once the engine is shut down the brake sets up. To tow a dead machine you remove the floor plate and there is a hand pump to pump to release the parking brake. . Now since it has been many years since i have done this i can not remember for sure if it is on the left or right side . I only had to do this once to move a 750 after we pulled it out of a drilling pit when the know it all operator literately BACKED the dozer down into the middle of the pit to squeeze the pit . That is not how that job was done , but when i asked him IF he knew how to squeeze a pit i got OH YEA DONE HUNDREDS of them. and hour later i get a call from him sayen he is stuck . SOOOOOO that meant i had to go up with another dozer and drag his donkey out . When i got to the location at first i did not see the dozer or the so called cat skinner . He had left to go home to get dry clothes . The 750 was in the middle of the big blow pit and the only thing out of the water was the ROPS the air cleaner and muffler . And no one 750 was not going to drag it out . Had to have another dozer come in and drag the dead one . To load it i had to pump off the parking brake and shove it up on the trailer . Pull the floor plates and you will see it and stick a pieces of pipe or a bar in it and PUMP .
 
So one unit? Like a transaxle basically no hoses to the final drives like an excavator or manlift? Never saw one my advice was just general but sounds like not applicable to this machine
