YT3 Error

rockyridgefarm · Sep 22, 2018

I am getting an error fairly frequently. A re-boot helps sometimes; it didn't today Here is the handy description from the manual:

Anyone have an idea what this is?

TIA

I did get answers from Yanmar, with especially great help from Marvin's Mowers in Muskogee OK. It looks like a restriction in a fuel line and I will report back when it is resolved.

Was doing some searches and found this. Seem this is inline with your issue.

Looks as if the main culprit is rubber fuel lines being kinked. I flexed them looking for a pinched line - the separator output line has a pretty tight bend - it may be the culprit. I ran it hard for an hour without incident. We shall see.

Well, the error returned. It seems like using the rotary cutter puts enough load to trow this code. I've tried looking for a pinched fuel line - but no success

How big of a rotary cutter do you have? I run a 78 inch heavy flail that normally takes more power then a rotary without issue.
