L4310 steering concerns/fluidquestions

[l4310kubota]

Hi I just recently acquired a Kubota L4310 and I have a few questions I haven't been able to find answers for.


I have read numerous posts/sources that my tractor has one huge hydraulic system that everything from steering to rear and trans shares, but I have also read other things that state otherwise. All my searches seem to be a mess of beat around the bush google results and headaches.

My main concern is The steering on it feels tough and it screeches, almost like a car without power steering fluid. I have read about the water issues these have that moisture gets in through the top seal of the steering tube and rusts the bearings in the steering controller, maybe this is a symptom? I am not sure.(Also front wheels kind of wander and the steering wheel can be turn a bit before the wheels start turning.steering feels like entire front linkages are held together by bungee cords)

Other than that I just want to be able to check and see if everything has its correct level of fluids, but I don't know the level check locations besides the rear sight on the rear.

btw this is a real nice site!

I have attached a description of how the L4310 power steering works.
It is not at all like a car or light truck in that there is no feedback to the steering wheel.

There is a pump for the power steering and another for the 3 pt hitch etc and all share the same reservoir.

Thanks Dave,how would I check the fluid level in the transmission?

Like you said it's the rear sight glass, the whole system uses the same fluid throughout.

Look up under the front end while a helper turns the steering wheel (engine off!!). You'll be looking at the steering linkages. They tend to wear over time. Find your loose/sloppy joints and repair them. Also look at your tie rods, the ends can seize and cause issues. If nothing in either one of those points, you'll want to pull the steering assembly apart for inspection. Have seen quite a few of them get stiff/seized bearings in the column, and have also had a few failed steering controllers in the past-although that's uncommon.

There's also the possibility that the kingpins (on 2wd) could be getting tight causing issues, OR less likely, FWA axle/knuckle issues. To isolate either, you can lift the front of the tractor so the tires are off the ground & then remove the tie rods and try to turn the wheels manually with your hands. They should be free.
