Reverse gear slow

[Gr2000guy]

Gr2000 real slow in reverse gear.
Any ideas?

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.

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.

Or debris captured at a limit point.

My L3710 tractor would barely move in reverse. I thought it was a stupid millennial mommy-culture safety feature. Turned out a bolt had fallen out of the pedal apparatus.

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.

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.

Point is, you can always make it new again, if desired. It's just not always worth the time and cost, unless it's getting very bad.

Yeah, it's a little sloppy and sticky but not horrible. I've seen worse and it is fully controllable.

On Deere 318 and 420 tractors the arm which connects to the speed control rod coming out of the transmission is held on by a roll pin. When the hole for the roll pin in the arm gets sloppy the arm slips on the rod and you will lose speed in one or both directions. Even a small amount of egg shape in the hole will make a big difference. The fix is to reweld and redrill the hole, or buy a new arm. Usually the speed control rod hole is not worn sloppy.

Look in your control linkage for wear spots reducing the throw of the arm on the transmission speed control rod. You may also find the limit is intentional for safety purposes and you will need to modify the linkage for more throw towards reverse if there is no slop. You will be able to tell by looking carefully at your linkage.

You might want to drive a known good model of your tractor to see how bad yours is compared to normal before you start work.

I am not a Kubota expert but have heard GR 2010 units have had factory recalls for transmissions. Might want to check for yours.
