I had gone as far as the hinge point of the ROPS but not to the top. It kept spitting fluid. If you look close you can see the last dose on the top of the left fender.
The real problem is the small capacity of the tank, only 2.5 gal. This is fine for steering and 3point but when you add a FEL it stretches it to the max. When pushing snow or manure piles up as high as possible when the tractor starts to climb the pile the vent spits out fluid and you don’t have to loose much to make the system start sucking air. Plus it makes a mess and is expensive to waste.
Time will tell how this works. Heading out now to do some yard work. I’ll let you know what happens.
