Honda Buffalo Classic HRU216M2 Questions & Answers

No it can't be changed on the go. You must disengage, change gear then re-engage

I was told to stop before changing gears, and to push off before engaging gear to increase the life of the gear box. I learned to be pleased with 2 to 3 years use out of a machine used commercially.

I have a Honda HRX217 which is self-propelled as well and I can easily change speed on the go. Doesn't seem to have any affect on the mower though I often do stop or at least slow down so i can be sure it has changed to the right speed. Not sure if its the same with the 216 though I would imagine it is

Hey Dennis, now while I may not have one of these myself (yet.... getting one soon) my friend does and I have a mowing business which we often use his mower for. If when you say the self propelled pro series you mean the HRU216M2 (the top-of-the-top-of-the-range one) it is rather heavy (around 60kg from what I remember) but if you have a trailer or ramp it should be fine. It is self propelled as you know already so it is a dream come true for big yards and thick grass. Tried using my own push mower yesterday on foot-high grass and it was absolute torture. The HRU216M2 is incredibly powerful though and has a blade brake which is helpful. As for the price RRP is currently $1,750 but a few places have them at $1,449 so its expensive but well worth the price. Not sure about trade-ins it probably varies by dealer so maybe ask your local mower shop.
Hope this helps.
James :D
