I have been meaning to build mower racks for ages,but just havnt been able to find the time. I was offered mower racks from a shop years ago,but turned them down as I was just too busy to collect them.
While ive got no solutions currently with the exception of making provisions for 5 mowers (Specials and Roto 3's that fit perfectly under my workbench,The racks eventually will be my preference.
Also was going to make perfect fit fabric mower covers in green with the Sheerline/V or Special logo on the front to suit specials and rotomos as my wife is a Mean Sewer...But that too has been put in the to do basket as well

So racks for me...and the plastic containers from bunnnings/masters and the like store a lot of my parts and stack nicely.
