Feeling sheepish.. I finally opened the hydraulic tank. There were plenty of bubbles. Then I noticed that the bubbles looked pretty far away. so I added and added fluid. Bought a new jug and added some more! I am pretty sure that it was closing in on 2 gallons. I haven't taken the temps yet, but 4 wheel drive has returned. I still need to change the filter for the hydraulics yet.....any suggestions there would be helpful.....I can't make out the numbers on the current filter. Speaking of the fluid, would running synthetic be of any benefit here?? Also, I was moving some wet dirt and mud would collect on the tires only to be scraped off by the frame where the platform that my feet rest on. What a mess. It also gets scraped off where the cooling air has to get into the engine. While I could make some sort of scrapers, I think that 2 inch wheel spacers would or likely would take care of it. Will the hubs survive the stress of adding the wheel spacers? Thanks for the advice!
