G'day VM and Norm,

It’s likely they optimized their machines to run this way, like in the parts image.

I haven't been able to find any images of Rover blades that would suggest they are able to be used in the opposite direction.
meaning the rover blades are made with the cutting angle on one side to suit one direction.


Reversible blades are usually like the blade A below ,showing which edges are sharpened ,these are flipped over but the
cutting direction remains the same.

I guess if people run the Rover slasher the wrong way they would sharpen the edge of the blade to suit that direction.

Image below ,blade B shows how the cutting edge would be if you changed the cutting direction.

If the slasher was made to cut in both directions the cutting edge would typically be beveled to suit but it's generally on one side.

Also it would be mentioned in the owners manual.

Cheers
Max.
