They say it's universal but it's not. It's made to fit the front end of a Dixon-Black Bear model zero turn mower. Didn't fit my Cub Cadet. Inside dim of the tray are width 16.250", length 4.750", height 3" without fastening straps, 5" with. I had to buy it to find out the dim of it. Kind of like Nancy Pelosi's comment about Obama Care, "We have to pass it to find out what's in it" LOL. SLE said they didn't have time to measure it and get back to me over the phone, but once I ordered it, they got it here by Fed Ex in a timely manner. If you can find a way to "Jerry Rig" it onto your mower it's just the right weight for the front end of a zero-turn. I'm still trying to figure out how to attach it to my Cub Cadet without drilling holes in my frame, which would weaken it. Tray weighs 10 lbs, weight is 18. Very well made for the price. The tray can take 3 weights. The kit comes with 1.
