Hi TonyF, and a warm welcome to the forum. Its great to have another Scott Bonnar owner on board.
I have a Scott Bonnar Model 17 electric as well as my Scotty 45 (petrol) and I notice that the Model 17 Supercut has a 3 HP single phase motor....a half horse power unit may, I feel, struggle in fairly long grass, especially if it is a 17" cutting width machine. It's a bit of a pain, but you may have to raise the cutting height in future, if you find your grass has grown to such an extent again, this will take the strain off the motor a little.
