FRONT WHEELS LOCKING UP

[GRASSMAN]

Hi guys,
Looking for info or fixit ideas as to my 03 Toolcat having the front wheels ''lock up''. It has happened 2 times before, but all of a sudden comes out of it and works fine the rest of the day.
Problem starts out as I'm using it in the all wheel steer mode the front wheels all of a sudden lock up(almost as if I lifted the safety arm?). I have tried holding down the diff lock to see if something works in that mode, and does nothing. I've taken it out of all wheel steer and still no go. Then all of a sudden it seems to come out of it and works without problems rest of the day.
This last time it happened, it machine has been sitting for about a week or better and when getting in to go with it it's locked up?
I changed all filters and fluids prior to the this last incident I should add.

Any thoughts or suggestions would be appreciated as to what I should start looking for to fix the issue.

Thanks

Been there, done that. Unplug the rear axle speed sensor and it's all good... except the caution light stays on. Or, fork over a few hundred for a new sensor.

Where can I find the sensor to unplug.

Read the oeprator manual. In the Display Controller instructions it tell how to turn Axle matching off. With it Off, controller will ingnore the speed sensors and will not give an error code.

Just curious if this applies to the 5600A models as well. I looked though my owners manual and did not see anything related to disabling axle speed sensors.

It would apply if the software was ever updated. But since it was a software change later on it was not printed in the early version OP manuals.

Ok thanks - if the software has been updated (which I believe it has) then what buttons do I press on the display to find this option?

With key or keyless panel turned off, push the Speed/Hrs/RPM selector button until RPM displays then hold button down 3 seconds until LCD changes (this puts controller into setup mode). If you have keyless panel it will ask for code (enter owner password) then 2 spd should display (options to turn on or off in here are 2 speed, Hi-flow, axle match depending on how it is equiped). Push the RPM button again until "0---0" displays, this is Axle matching engaged. Press the Work mode button to toggle to on or off positon in any of these options. Axle matching Off/disengaged is "0 0" (no dashes). Press and hold RPM button until "donE" appears in LCD (this locks in the program, if you start machine or turn key before "donE" appears it will revert back to previous selection) Push stop button if keyless panel or start machine, it should be ready to go.

Great - thanks for the help.

The instructions were perfect for disabling axle match. Again, I appreciate the help you provided.

I have been having issues with my 2003 Toolcat as well

My front wheels are not turning at the same speed as the rear

One thing i did notice was if i put the machine in axle match mode the front wheels would only turn a couple inches and then lock

When its out of axle match is will spin but in my opinion its not spinning at the correct speed to match the rear

When in reverse all 4 spin at the same speed (reverse functions as it should)

Been having issues with forward for over a year off and on have unplugged the rear wheel sensor and did nothing

Have replaced the front speed sensor and it didn't fix it

I have replaced the solenoids on the pumps and one of the solenoid stems (might have been bad but since this keeps acting up i'm having issues diagnosing what is the problem

If just driving around it seemed to be ok all winter but if i ran the finish mower it was more prevalent of a problem this spring

Maybe somebody has some advice

Thanks

Update

Swapped the directional valves on the hydrostat (didn't replace just moved one from one side to the other???) replaced all the solenoids and the machine is back going again (replaced with aftermarket solenoids for a fraction of the price

part #6682953

Throwing a rear wheel sensor code 50-14 i have a spare so that will be replaced next
