I took mine off (1979 B7100, welded some washers where the rubber pads has bent and rusted through, bought a cinch down seat cover / pad from Tractor Supply, and installed it.
I then installed the rubber cinch strip along the edge of the tractor and drove it.
2 years ago and it sits outside under a tarp (for now) and it is still holding up well.
Out of pocket cost was like $25 and some time / spraypaint.
Good luck.
