Zero oil pressure on my Kubota

[r.u.greens583]

Good to discover this forum and get insights from members here. So I thought my fall was about to be ruined.. Just got the old Kubota out to start clearing some of the leaves and brush, and a mile back in the woods the oil pressure gauge drops to zero. I freaked, shut it down, and sat there for a good 10 minutes thinking the engine was toast. Checked the dipstick, oil is full and looks good. Everything under the hood seems fine. Drove it real easy back to the garage, still showing zero pressure. Now I'm wondering if it's just a busted sensor or gauge. Anyone ever have this happen with a zero-turn or tractor this time of year? What could be the problem and how to fix it?

You probably just tripped a faulty oil pressure sensor or the gauge and also I doubt its the engine itself because the dipstick is showing full oil and the engine isn't making any noise. Just go ahead and replace the sensor first; its a good place to start and we can see how it goes from there

Before you spend money, check the wire connection at the sensor itself, corrosion or a loose ground can cause the same symptom. If the connection looks good then you can swap the sensor, they're cheap and easy to replace

I agree with @wovenhair the sensor simply failed and stopped sending a signal to the gauge.
The fastest, cheapest troubleshooting step is to replace the sender unit. They are notoriously fragile, especially after sitting dormant for a few weeks or when exposed to vibrations and temperature swings.
You can usually find the sender unit threaded right into the engine block near the oil filter or next to the fuel pump
