I don't know if this is possible or would harm anything, but over the yrs I managed to TOW a few dead machines, like skid streets, by having a person sit in the machine and push on the hand controls in the direction it needs to go while being pulled
it seemed to allow thin gs to move easier as if reveling pressure, and allow them to roll more freely!
NOT having anyone inside machine to do so, made them almost impossible to drag , as if wheels locked up!, unless having a very heavy machine that could man handle them!
I am not talking dragging it FAR, maybe a 100 yards,
but of all the time I did so, never was any issue's on OLDER, foot,hand controlled machines, any how
just a thought and NOT claiming to be any expert here! just what I found that made moving some dead skids easier!
if in a pinch, if working alone, I was also able to bungee cord hand controls into position too!~
