Online parts diagrams for each model really useful

The spare part came fairly quickly, so that was good. However installing it was far more difficult than expected. There were no instructions, although I managed to work out how to do it reasonably easily. The worst thing was that no handle was included. I have quite reasonably assumed that it would be part of the cover unit that I had ordered. Fortunately the old handle was undamaged but it was almost impossible to remove from the old cover and I had to cut up the old cover with a saw in order to liverate the old handle for fitting in the new cover.

Part arrived as promised and mower was back up and running within minutes thanks Chris
