OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Four Stroke Lawn Mower Frames 3 Speed Gearbox conversion for a HRU215

Hi all, Long time lurker here.

I've just inherited a HRU215 which is in mint condition except the 2 speed tranny is on the way out.
My question is has anyone fitted a HRU216 3 speed gearbox to a HRU215 mower before or knows whether it can be easily done?

TIA
Nick
