Mines 3x3 as well MF
I would post a pic, but I am embarrassed as it an absolute mess at the moment
I made a 3 shelf one out of treated pine - took me a whole day and drove me nuts as I infinitely prefer metalwork. Still, it cost me nothing as I got the pine for free (builders next door stuffed up roof pitch on 2 units and had to rip it all down and throw it away) and a shoebox full of roofing screws from the tip for $10.
It holds the trimmers hung over the top with engines down. Kicking myself I didn't put the top shelf 30-50mm higher as the Stihl and Bolens straight shafts are too long and hit the ground
I couldn't see myself making another 2, so I splashed out and got 2 of these
https://www.stratco.com.au/au/storage/garage-shed/heavy-duty-rack/ Got them on a bit special, but I don't think I got out of it for under 600. Most shelves are 500mm deep, so too stubby to fit a victa on. They just fit on 600 (but I put a piece of iron behind a wheel just in case).
Shelves paid for themselves instantly - no stress or strain or backache putting these up. Bloody solid too.
3 mowers on each shelf, and the blowers, ryobi expand it attachments and hedgers fit on the top shelf right up at the roof.
It's under a tree, so only gets the warm sun in the morning and shade through the heat. Otherwise, I wouldn't be comfortable putting the things up on the top shelf
The only thing I didn't think of is the wire shelving material latches the wheels in - and it doesn't conform to Victa track width front or rear - so I cut up the box the shelf came in and used it as a shelf liner.
I have since picked up several sheets of good Big MDF on bunnings clearance (rough corners) for $8 a sheet (and incidentally a new Ryobi circular saw to cut it with on clearance for $30), so will be cutting that soon.
Only prob is I put it on the top shelf to store it dry until I cut it - forgot the other day and almost knocked myself out on it
