Hi

Unfortunately, I no longer have this mower. I have looked everywhere and cannot find the dimensions when folded down.

My guess would be approximate dimensions are around 70cm long × 38cm wide × 40cm high.

However, I'd recommend measuring your plastic storage box first to ensure it will fit, as this mower, while compact for its class, may still be too large for some storage containers. The handle folds over the main body, but the mower itself maintains its footprint in terms of width and length.

Thanks
Mark
