I posted a while back, as did others, about a hydraulic shudder developing on the GC series tractor.

There were several possible diagnoses of the problem.

One person said that theirs ended up being an engine that was missing slightly, my problem ended up being a fuel filter. I've put 30 hours on since the fuel filter change, with zero shuddering from the hydraulics.

So it would appear that a fuel filter, that only looks slightly dirty, even if the tractor is put on a dyno..........and tests good, could cause other problems. As mine did.

I was also experiencing an 'overspeed' situation'. The tractor would tach up to 3,000 rpm's, or a little more.

The tech that was looking at it in my driveway, was eyeballing the Banjo fitting..............he said, It looks like the tractor could possibly pull fuel in from the return line, and cause the engine to get more fuel. He said he had never seen a design such as this.

Anyway..............fuel filter was changed problems disappeared. 30 hours should be enough to call it 'fixed'.:cool2:

Interesting, fortunate you didn't end up chasing more expensive fault-finding diagnosis. Nothing feels like making things right, especially when a little effort saves significant expense. Must be a relief.

I agree.

I just hope that my experiences help others.
