I know nothing about the particulars of a GR2000, but in nearly every other case with every hydrostatic tractor, loss or reduction of momentum in one direction with no apparent effect on the other direction is due to control linkage.Gr2000 real slow in reverse gear.
Any ideas?

Look for wear, slop, or a pin that's fallen out. With tractor turned off, have someone move the controls while you watch the actual lever on the transmission itself, to verify complete range of movement.
I had a 1963 Cub Cadet 123 who's hydrostatic control linkage was so sloppy by the early 2010's, that it was getting hard to control the speed at all. I ended up replacing all of the linkage but one piece I couldn't find. I think I sprayed some weld onto that piece and ground it back down to original profile, to repair the wear.I had similar with my G2160. Now it gets right up and moves along in reverse. Though my linkage still has a lot of slop and stickiness. Just not sure how much further I want to take it.
