Kubota F3680 - Steering Wheel Keeps Turning

[Gary55]

Steering wheel is able to keep turning past full lock.
It's possible on full left and full right locks.
No fluid seems to appear underneath. The steering wheel is not loose or free
spinning when fully turned but there is resistance.
please can you help. year:2008
Thank you!

Normal with fully hydraulic steering. There is no "lock" or stop for the hydraulics, only on the axle. Stop turning once wheels are at their stops.

Thank you very much. I've noticed positive camber on rear wheels, definitely rear left. Seen on other kubota's too. I guess this' normal.
Good machine only bought recently

Yes, they do have some camber in them. Very good machines. I kept 4, well now 2 going for a parks and recreation municipality. Other two topped out our hours to replace, went to auction.

Have you experienced any excess wheelspin on the inside front wheel on yours! Turning left or right, I have to feather the pedal to get round. I did ask this question a while back under kubota f3680 wheel spin - hope it's OK to ask again! Tried different things with 2wd/4wd. Deck up and down etc. Rear wheels push fine

Get the WSM and check rear wheel alinement, if the toe in is not right it will do that.
Also check the tire pressure on a 4 tires as that has an effect on it too.
If it still doing it, with it in 4wd, lift one rear tire off the ground and check for lash of the gears, (turn the tire back and forth till you get it to stop) , compare right to left.

I have not experienced that. Could your diff lock be stuck in the engaged position?

Wow! I never realized this, although I have realized that the steering wheel will end up at different positions during use, when the tractor is moving in a straight direction. I never really thought about it. I guess I may have thought if the wheels hit the stop, a pressure relief valve would open, and that would explain how the steering wheel would end up in different positions.

Or course, I can see the front wheels on my tractors, so would have little reason to keep turning the steering wheel...

Now I have to remember to turn my tractors wheels to full lock and see if the steering wheel keeps turning! The challenge is not doing the simple test, but rather REMEMBERING to do it!

That is also the reason the steering knob some guys install is NEVER in the correct/same position.

I checked my much smaller BX today when using it. When the wheels reach the end of travel, the steering wheel locks and doesn't turn more. Might turn slightly if you held it in position, not sure. This is hydraulic steering.

Next time I use the slightly larger B2910, I test that one too...and report back if I remember to do it.

Yes the BX2200 is hydrostatic steering.
Your B2910 is NOT hydrostatic, it's standard PS.

Some Hydrostatic steering controllers and cylinders are tighter than others, and the stop at the end of the steer is more dramatic.
Put a piece of tape on the center top of the steering wheel when traveling straight forward, use it a while like that, you will find that the steering wheel alinement will migrate all the time.

I was responding to the OP's comment that his hydrostatic steering wheel keeps turning after the wheels reach the full travel point.

Was just verifying that with my hydrostatic steering the steering wheel locks when the max travel point of the wheels turning is reached at either end. Nothing more...

 

[North Idaho Wolfman]

not sure. This is hydraulic steering.

Missed your period in there.
Read it as a quandary.

LOL. Actually, I did not put the period there...I seem to have this issue all the time. Auto correct happens and it seems to take place AFTER I read what I typed.

I just meant to say that I was not sure what the steering set up was on the B2910. Wasn't questioning anything. But I find it interesting that his hydrostatic steering would allow the steering wheel to keep turning when the front wheels reach the turning limit, but my BX2200 steering wheel stops turning when the wheels reach their turning limit.

Should his tractor work differently?
