John Deere 2030 3 point will not raise

[Peacocks]

The 3 point hook up has been gradually slower about raising.It had gotten to the point that you had to speed the engine quite abit to raise.Now tries to raise the mower deck but can't

Hi neighbor!! How long since hyd filter was changed & sump screen(parts key 30) was checked/cleaned? Is hyd fluid level at the full mark?

 

[Peacocks]

I spit the tractor 2weeks ago to put a clutch in it machanical pto clutch was out put new fluid in then, this morning put in new filter fluid is full

 

[Tx Jim]

Have you checked the sump screen?????????????? Does steering operate correctly? Does pto operate correctly?

 

[Peacocks]

Sump screen is key 30 in the drawing TxJim posted.

Yes dual stage pto is mechanical but it's input shaft also powers the trans pump. After checking sump screen I'd suggest to check stand-by pressure which should be 2250 psi. Then check for stuck pressure control valve in photo.

screen dirty but not stopped up & check valve not stuck.I noticed when I disconnected mower arms raised but shuttered when raising and fluid sprayed out of fill {cap off}unable to check pressure

Plug with squere on righthandside of 3pointcasing....takes a 1/2 t-handle.....open it and take flat screwdriver and inside screw adjuster in 1 complete turn to get a neutral range on your lever .

Sounds as if seals are blown on rockshaft control valves causing oil to come out filler hole.

 

[Peacocks]

thank will be pulling cover in the morning

 

[Tx Jim]

Does your tractor have a FEL? If so how is it hyd controlled? Does your tractor have scv's(rear remotes)?

[Tx Jim]

Trans pump lubes trans,supplies operating pressure for hyd hi-lo &/or hyd ind pto if equipped plus supplies oil to frt hyd pump.
