I actually am surprised that we do not hear about more SEE accidents. My guess is many buyers are new to medium size backhoes and backhoes have plenty of pinch points. I wonder if folks are just not using them and keeping them as garage "queens" or ones that did get hurt just do not talk about it.I'm guilty of operating the pedals by hand, while standing on the ground, somewhat frequently.
With my knees and back I'm more likely to hurt/kill myself getting up on and off the machine, I think.
Besides, I run mine at 900-1,200 rpm for the most part, so nothing moves quickly. Still, it's not the safest thing to do, so your warning is well warranted, Speedwoble.
I do have my own rule that the high throttle switch gets flipped off before I get in or out of the seat. I guess we need to install a pressure switch under the seat like a riding lawnmower so the throttle switch is locked out until the seat is loaded up. I am guilty of accidently depressing the left pedal when I am getting out of the seat. it means the boom is rotating away from me but I wish I could lock both of them easily. I have gotten a lot better with the boom lock of late after a few marathon digging sessions. I am unsure if air gets into somewhere when it sits and make it hard to latch or I am just getting better at it.
