Cub Cadet Zero turn fuel tank

[Fuddy1952]

I have this mower. Zero turn A Force. I'd like to add an axillary fuel tank. The other side looks like the side with the has tank. The dealer says it can't be done...but to me it seems simple enough. A tank, line, filter, valve, T.
There's even a place for one molded into the plastic cover it looks like. Has anyone ever done it? Thanks.

Do the higher end Cubs have dual tanks? I know Hustler's do that. Low end models have 1, high end have 2. You may be able to get the tank from a higher end model and retro fit it to your mower.
