Bought rear wheel weights last week. The seller was half my age and just picked them up and put them in my van. When I got home I realized I wasn't going to be able to pick them up so had to figure out how to get them out of the van and on the Cub by myself.(safely)
I lined up my hand truck, blocked the wheels and slid one weight down the handles of the hand truck.

Here it is after sliding down.

I brought it over to the Cub and placed two 2x10s about 4 ft long on the rim forming a V. I rested the hand truck on top of the V with the handles blocked up for stability.

The weight easily slid up the handles of the hand truck to the V where I just stood the weight up.

The height was perfect and with a little jiggling of the weight to line up the holes the bolt slipped right through. Secured one to hold in place then put all 4 on with lock washers.

This really couldn't have gone any smoother. Hope this helps someone else!
