Combines Did Gleaner make a machine for WhiteIJ

Yes they did. Two models. They were: The 2500 and 2600. Used Cummins engines. Gleaner's still had the Air Cooled Engine at that time.

Seems to me the T2500 equalled an R52 while the T2600 was similar to the R62! I remember inquiring with my White dealer at the time about the T2600; - he didn't seem too interested in following up, since he had been selling "against" Gleaner for years with the 9700's and 9720's!

What year modelsIJ

You are correct. Except for engines and decals, they were identical. Seems I heard that most of the "White" Gleaners were redecaled to "Gleaner" Gleaners eventually.

I believe the years would have been 1992 and 1993. In 1994 the Cummins and the Duetz engines were available in Gleaners. Todd

2500-Same as R-52
