Can u tell me what size of hydrolic pump is fitted to 1850 john deere tractor

HAVE YOU CHECKED THE TRANSMISSION/HYDRAULIC
OIL? THEY ARE THE SAME. ON SOME TRACTORS THIS
CAN BE CHECKED AT THE REAR OF THE TRACTOR JUST
BELOW THE SEAT. IT COULD ALSO BE A BAD HYDRAULIC
PUMP.

How do you check hydrolic fluid level in a John Deere 2030?

Right side foot plate next to the rear end housing is a cap you screw off with your fingers. It has a dip stick under it.

All hidraulics funtions are dead, no hydraulic power in machine.

first thing I would do is test the pump itself even if no wear is found you could have a GPM loss.
So you need to do a flow test on it to find otu how much the loss is and check it to the specs of that hydrolic pump first.

power steering pump is mounted on front of engine where the tming gears are. Shaft leaks into crankase. Hydraulic fluid circulates through transmission, main system and power steering. Common problem with the 1020.

hydraulic pump may be going out, you have to have a good working pump for your hydraulics to work right, there are also some check valves that could be leaking, this will also give you a low pressure reading, low pressure will also effect pto engagement
