I have a 2640, should be the same just a little more HP.
If you have any slop in the steering,
Left side above clutch pedal there is a cover about 3.5". Pop it off with a screwdriver and see if the big bolt inside is tight. 200ft\lbs if I recall correctly.
If you use the tractor/loader with this bolt loose you will tear up the spline on the shaft and lever. New parts are about $900. Just guess how I know.

Mine had over 5000 hrs on it when I replaced these parts.
Ive had ours for 3 years and repaired the following so far.
Rebuild water pump
Rebuild alternator
New voltage regulator
Repair leak in radiator around neck
New front tires
New bushings in steering plate between tie rods
New steering shaft and lever mentioned above
For its age I guess I cant complain, good strong running tractor.
