2016 Kioti RX7320 severe vibration

[jgmaciejko]

I just purchased a 2016 Kioti RX 7320 with 500 hours from Williams Tractor in AR. I live in northern Ontario Canada and had to pay $2800 to ship it to my acreage and to my grief the tractor exhibits severe cab vibration in mid range 2nd and 3rd gear mid 2000 rpm 2wd or 4wd). Identical also vibration occurs when coasting down an incline in 2wd with a bucket load of sand and I apply the brakes which seems to indicate when brakes are applied the tractor engages 4wd and maybe issue there except the Kioti dealer had taken the front drive shaft off and issue still occurs. Any help would be appreciated. all cab/loader bolts have tightened and tire air pressures confirmed. Another dealer drove identical through same conditions with no vibrations.
thanks

Tires loaded with something to cause unbalance ?

Hi Jim,

Are you saying the machines vibrates when coasting, even in neutral? If so, does that rule out any engine and our transmission issues? I'm not sure I followed the scenario under which this occurs. If coasting down an incline, with heavy load in bucket I'd first inspect the road surface. Is it washboard causing the load to bounce?

Have you checked the adjustment on the front axle pivot? Under the maintenance section in the manual.

You could try changing your tire pressures, I have seen tires set up a vibration at certain speeds and loads.

Do you have R1 or R4 tires? And does the vibration happen on all surfaces. (soft dirt or paved road)

My RX6620 will vibrate on a hard surface. I have R1 tires. In soft dirt there is no vibration.
