Tractor
2003 Farm Pro 2430
Hi all! This is my first post ever on here. I bought my first tractor about 1 month ago. It is a used 2003 Farm Pro 2430 with Koyker 160 FEL. It was a trade in at a local new holland dealer. There was some minor things like electrical wiring being out of sort and not hooked up. The tach/hour meter being a couple things that weren't hooked up even. I hooked them up shortly after I got it home. I've put about 21 hours on in since I've had it. Everything seemed to work great until a couple days ago. I was working the tractor pretty hard running into rocks and moving quite a bit of dirt. My steering seemed to get quite hard. Now steering the beast is really only capable when the tractor is moving. When I turn to the left sometimes it works fine but going back the other way it doesn't really do good at all.

There is plenty of oil in the resevoir and in can hear the pump trying to work when trying to steer. Before this happened i used to be able to continue turning the steering wheel to the left without it stopping. Since it seemed to start acting up I actually hit the stops in both directions. I'm hoping it's only a simple rebuild on the front steering cylinder. I don't want to have to replace the pump or the power steering gear as they all it in the parts list.

Can anyone offer me a some knowledge or info that may help me to fix my issue?

My guess is you blew the seals on the cylinder. Try lifting the front tires off the ground with the FEL and see what happens.

When I lift it with the FEL the wheels turn both ways and the steering wheel hits the stops like it should. I didn't mention either that there wasn't any leaks outside of the cylinder.

Hang on here, don't buy parts you may not need. I agree that it sounds more like the pump than the cylinder. When a cylinder bypasses, your steering wheel becomes ineffective. When the pump quits working, good seals in the cylinder are what makes turning the wheel difficult.

At least that would be the way it works with my two pump tractors. Yours only has one pump to work everything. So the test of fire here will be whether or not your rear lift will lift a load. Not just itself, but an actual load like a mower or cultivator or something. If it does that, the pump is ok - and you may be looking at either a priority valve issue - or a steering controller issue.

Mine is a two pump setup. There is a separate reservoir in front of the radiator for the power steering.

Ok, but that would have been good to know up front. That now introduces a new factor into the equation. The independent (front) steering pump has an adjustable relief valve. Yours may be
(a) dirty
(b) in need of adjustment
(c) broke
Given this new info, you may wish to take a new look on the situation

Tommy - I'll call during the week when I'm home. I'm out camping for the holiday weekend.

Greg- I would like to know the same as what Tommy asked about the valve.
