Took about a week to process the order, then about three days to ship to Iowa. It was delivered by R&L Carriers. They gave me a window between 10AM-4PM that it would be delivered and the driver gave me about a 30 min heads up. Little difficult when you work away from home, but made it work out. It came wire banded to a regular pallet. Was able to use the loader quicktach to pick it off the semi.
Overall, I'm really impressed for the price. Welds are mostly good, with the exception of the quicktach pins not having full beads, but I don't foresee this being an issue down the road. Paint is ok, could be better as they missed a couple small spots on the bottom. No issues with fitment on the JD loader mounts. I think I'll be happy I went with the 60" version and not anything bigger.
My 4600 has a third SCV already mounted, but doesn't have the lines or cables to actuate it. JD used to sell a kit, but it puts the lever up on the right fender. I would rather have a button on the joystick, so I'm going my own route with a diverter setup. Ended up doing hoses for the loader instead of hardline too. I'll put up a final list later, but think I'll have ~$140 for the valve, ~$140 for fittings/hoses, and another ~$50 or so for the electronic bits.
