You could always Hondarise them from a knackered Honda base? At least the axles alike should accept wheels from other mower brands. I have a set of Sanlis that I have successfully adapted to fit on Victas and they feel more substantial that the lightly constructed plastic fantastics Victa have been pumping out since 1975.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
