2004 Jinma 284LE hydraulics prob

[Staff308]

I recently baught a 2004 284 LE tractor i seviced everything but hydraulics at start up the front bucket works fine but after 15min of running the bucket going up and down is so shaky and fast it shakes the whole tractor like its going to fall apart! what should i do and how do i check fluid level. Also on the back of the tractor there is a big bolt w a hole in it and fluid sometimes leaks out what causes this? My question is will to much fluid cause these problems or to little fluid ? The tractor set for 2-3 yrs but other than that it worked fine till now thanks for your input i really need some help also i never owned a tractor and im not reall savy about all the stuff but i am mechanically inclined

Another valve should help solve your problems.

You only have 4.2 GPM valve flow, so this valve should work for you. It has float, regen,and PB.

Surplus Center - 2 SPOOL COMPACT 10 GPM JOYSTICK CONTROL VALVE

This valve has float , and PB.

The tractor has set 2 or 3 years and oil is way high. You should check of water in the oil. Air and water in the oil and that is why it is jumping all over the place.
