new to posting so here it goes...I have a early john deere 4230..quad shift..the 3 point raises very slowly and jerks alittle coming up..its really bad on the colder days..steering does not work when 3 point is coming up..it operates pretty good on warmer days...if you are off the tractor you can hear some kinda clicking noise in front of the rear end where 3 lines meet..have not tring to change filter on the hydraulics yet..anyone have any ideal what is going on..i will have to take this to someone...I'm not very good at working on things...I have two left feet on things like this..
 
Then check standby pressure, do this by plumbing a 5,000 psi gauge and plugging it into a remote outlet, then engaging the lever in the proper direction, it should read 2250psi, if it is low the priority valve will low or stop oil pressure to the rear making it available to steering and brakes only, the stand by pressure can be increased by turning the stroke valve "in" a few turns at a time till it gets where you want it...keep trying and asking and we will help you with it...
 
I will try the filter and clean the screen...if this doesn't work I will be asking more questions.is the hydraulic fluid from rural king any good... I know its a lot cheaper then deere is..but is it worth using..thanks guys..
 

The parts manual is free on the JD web site . Real JD operator's and service manuals from the nice folks at 1-800-522-7448 .
If the hydraulic transmission oil doesn't meet JD specs, best not to use it.
 

Be wary of oil that meets JD specs for 303 transmission/hydraulic oil. That is an old spec.

I would give the Harvest King JD oil a cautious ok to use in that vintage of tractor.
Certainly better than the ISO 32 hydraulic oil or 90WT GL-5 that some folk pour into their tractor.
Buyer beware of discount oil. There is a problem out there with counterfeit econo oil being sold in expensive looking containers.
