I guess this would be the place for people to show and exchange ideas about home-made devices and modifications. Spring assisted gate lifts, etc. I'm making some wheel locks for my mowers made out of angle iron in a square shape: the front and rear pieces are upside down to drive over, with the edges up L shape to keep the tire from sliding all over. I also put pieces of pipe insulation (foam) around the trimmers shafts where they fit on the rack, this didn't affect their performance or weight and made them ride a lot better. I'll try to get pics posted, but very busy now.
