Good luck getting it on that easy. Those U-bolts DO NOT slide on like that. It takes two people to get the disk on. One to line up the U-bolt up with the bar and the other person with a hammer to tap/pound the U-bolt onto the bar. Plan on a good half hour to get the discs on the lift. I’ve been less than impressed with the whole Black Boar lift system. The manual lift crank is way too stiff for a cordless drill out in the field (doesn’t help that the grease fittings are bad so lubing the screw lift is made difficult/impossible). You better have some oomph to hand crank it.
I agree the manual lift is garbage. Having seen people break their backs and having to get on and off your atv. I was smart and went with the electric lift! Well worth the extra green!
