The stop bolt on a M,Farmall cant be used on a wide front, when equipped with a Schwartz front end, anyway on the one i got u cant. The nut end of bolt hit's a structural piece in the front end! Maybe you new that but i didn't,and i don't plan on dropping the bolsters shaft down to remove it! Firewrench time!

IH didn't use the stop bolt on the wide fronts for a M. Original attachment or later wide front attachment.

OK but this M is on the loader and everything kinda wore out,with that Schwartz,and it's got stops, when i would dump snow on a pile, and drive into the pile to far, it would kind go to far to the right or left, a good way to break a spindle, just trying to give myself some protection!

Fast,

Not that familiar with Schwartz front ends but have had one on a tractor in my past youth, about 60 years ago. There should be a hole in the bolster that will let the bolt be pushed out the top of the front end without the shaft having to be dropped??? Will have to turn the shaft to align with that hole. The cone portion head of that bolt has to be on top and in a certain place to allow the shaft to turn for full steering range. You may need to change holes in the shaft with another bolt. I think you will find you really want that bolt in place and not rely on the front spindle stops. When reversing an M for a cotton picker, you only had to remove the stop bolt and turn the fork of a single wheel or tricycle front so the tractor could be steered in the reverse direction.

Yeah that's a good point,and there maybe would of been room for a thin nut,if i had cut more threads on it before hand, and had a jam nut! But there are wear marks to prove its been tried, with a full depth nut. Thanks!
