Hello, I have a GX335 that developed a ticking noise last fall. It appears to be coming from the top of the hydraulics system in the back of the mower. It is not noticeable when first starting, but after a couple of minutes it gets louder. The speed of the tick does not seem to increase with engine speed. No noticeable decline in functionality in mower, but I am trying to sell, so would like to figure out what the problem is.
