I've been out of town for a few days. The front axle fluid was right on the money.
James, I LOVE the tractor. It is better than my old tractor in every way. The 4x4 comes in handy even finish mowing my yard so I can back uphill to mow next to things. The hydro alone was worth the upgrade. It cuts my mowing time way down because I don't have to pick one safe speed and go with it. I can go flat out on a straight, slow down for a sloped turn, go slow over a thick patch, then floor it again, all in less than a minute. I was worried over nothing in regard to the weight with loaded tires. In Med range "rabbit," it will accelerate uphill pulling a mower a lot faster than I feel comfortable going. The quick attach makes it unbelievably easy to pop off the bucket for mowing. The extra width of the R4s makes it feel incredibly stable. It isn't bouncy like my old tractor. It's smoother and quieter. It's just a big improvement in every way. There are probably things I'm forgetting to mention. Heck, even the steering wheel is a lot better. Gear tranny was really wrong for my uses. I haven't even been able to use the cruise control. It's just better on my terrain to be able to constantly change speed.
Really really really happy. It has even exceeded my expectations.
