1992 L3450 jerky 3 point please help

[david.phillips181]

Hi there new to the site and looking for ideas on ajusting or fixing my 3 point. My 3 point goes up and down when unloaded just fine. The 3 point will hold weight in the up position all night without sinking. If you pull the depth control level quickly and stop the 3 point lifts without issue. If you go slowly with the attachment on it jerks the tractor all over the place. 650 hours service has been completed. I quickly played with the one adjustment on th3 3 point without luck

Any ideas??

I would like to add I just removed my front mount blower prior to noticing this problem. Is it possible teh loader valve has something to do with my problem?

Any chance the front mount blower was serving as ballast and it's the weight of the rear implement jerking the tractor around more so than the 3 point's performance? I guess that depends if you have a loader on there now.

I'm one stuck with the jerky L3400 3 pt valve, so I feel for you. Good luck.

i just bought the tractor. its a one owner used for snow only. in mint shape. It is only jerky when being slowy raised in one fuild motion. I agree the offset of the blower would help but I know it will still shake the crap out of the tractor
