I manually place the bucket on it afterwards. The bucket has to be on the ground to get the loader off (at least with the JF FEL's I've owned). I just use a floor jack under the torque tube behind the bucket to lift it up, then slide the dolly under it. Even though there is still a lot of weight on the rear end of the loader arms, I can lift it by myself and maneuver it around when needed which is pretty handy in my smaller shop.Same here, I have a handful of each size. I have used them for my 54" blade, hydraulics for the blade, bucket, ratchet rake, Artillian fork set, heavy hitch and now the JD weights.
Do you place the dollies under the bucket when taking it off your machine? Or do you take it off than manually place them under the bucket?
