So my 2120 New Holland had been spilling out of gear also , after 10 minutes driving it , it would just go into nuertral by itself. New holland Brookville said it was fine after a few hundred dollars in shop bill. No Change. Greensburg took it in and Actually tested everything ! The problem is a FNR Switch they can get a short in them , they charged $75 dollars for the part , tractor runs now like never before !
