(ET) Re: pack not isolated from frame??



because of some red-orange paint I thought for a while it might be a 
wheelhorse 
but the the GE symbol is there on the front grill.  there's no hole up 
front 
where the PTO plug may've been. The tractor has been painted JD green 
including 
the name plate on top of the dash unfortunately and the data plate under 
the 
hood isn't there.  Unless I can get some info off the painted plate atop 
the 
dash I'm afraid all I'll have to go on is physical description.  the 
tractor's 
on the island and it'll be friday before I can get there again.

thanks for the warning/confirmation that I've a dangerous situation that 
must 
be fixed immediately.  I'm taking that to heart...
