There's a new product review in a UK trade magazine for the Cub Cadet XT2 PR1061E. , but with no mention of the engine manufacturer - who is it?
Interesting that the article uses the word electric as opposed to the more usual electronic - any significance there?
Amongst the claims made for the engine are easier starting after periods of no use, 25% reduction in fuel consumption and a 5-10% increase in power and torque compared to a carburettor equipped engine.
