Hello, new member here hoping for a little help.

I've just purchased an older Rover Rancher mower and I'm yet to decipher a model No#, so having a bit of trouble finding accurate info on it. It's missing the top drive sprocket/chain but the drive set-up is more like a Greefield e2000 mower then any of the Rovers I've looked at with only one chain drive as apposed to multiples.

The plan was/is to replace the chain and both sprockets, too easy except the lower sprocket is welded on onto the axel, still not an issue I'll just get 2 new weld on sprockets with appropriate hubs. Except I don't know what the final drive ratio should be? Could this be the original top sprocket HERE

But then I can't find a suitable 65 tooth replacement for the lower sprocket, they all seem to jump from 60 to 72. But I can still build a suitable top and bottom sprocket to achieve a similar final drive to the original, If I can work out what that is supposed to be.


This is the mower in question if it helps.
