JD 4320 Hydro Static Transmission Problems

[Hay Pirate]

My JD 4320 makes a loud grinding noise at random times when in C-3 or 4. When the "forward" pedal is to the floor. i have to COMPLETELY stop in order for the grinding to stop.
It only happens when going fast in the highest range, C.

I had the same problem a couple of times when traveling down the road. The problem stopped when I figured out that i didn't have the shifter completely in gear. Wiggle the shifter some and it should resolve your problem.

hm, good point! sometimes I have trouble getting it into C, so I'll make sure its secure.

Also, what is the button, left of the steering column, has a wheel with an arrow going around the wheel and one going forward?

You have a tilt steering wheel...?

I'm quite sure all 4320's have tilt steering as standard -- at least that was the case 8 mos ago when I bought my 4320.

If I understand you correctly, it is the switch for "LoadMatch feature keeps the tractor from stalling under heavy loads". Mine is ON all the time as I don't have a reason to turn it OFF.

I'll snap a photo with my phone for reference. I'm pretty sure you're right. I'll try making sure my shifter is in gear as well.
thanks.

That grinding you're talking about was one heck of a noise. I hope to never here it again.
