late 1992 I bought a new TR 86. Before the next harvest in 1993 ( so in my mind it was still a new machine ),I started cutting holes in it and removing sections of auger flighting to install this new thing called a AglEader yield monitor. That first year only aobut 100 were sold. This was early in the game. Of course now, on my TR89 just delivered my Al yield monitor was factory installed.
