Okay, I hate to admit this because one, I try to be safe, and two, I hate to look foolish, (which seems to be my natural state so why do I not embrace it?).
So back in the DK45 days I was finishing a hot and tiring day mowing my alfalfa field with a 3 point HayMaxx disc mower.
I look to put the mower in travel position, (straight back instead of to the side), so I stop on level ground, PTO and tractor off.
I have the 3pt hitch up all the way so I can inspect underneath, but do not lock it in travel position.
I notice some debris that needs removing and go to the box at the back to grab some pliers.
Now, instead of being safe and going into the station then to the box, I be "Wile - E - Coyote Super Genious" and go from the back to get what I want by leaning up and over the box.
On the come down I hit the 3pt lever enough to cause it to drop 6- 8", still well above the ground so no problem there.
But, while this does not seem a problem, with the weight of the, (unsecured), disc mower, the drop causes enough momentum to "bounce" and then swing the mower into cutting position.
This whacks me pretty good with the safety bars of the mower and briefly pins me against the fender do the fact that was were I was at by this point of events.
Luckily, 1), the mower was not going, (I have never messed around with the PTO running, small victories there), 2), the mower was not secured and easily pushed back in travel position so I was able to get out of my predicament by myself, and 3), the Missus did not see that "stunt," (oh she would not have been happy, she - rightfully? - worries so).
Ultimately I did end up with a bruised body, (with the explanation to the B.B.L. as "I don't know." Luckily small injuries that just "happen" to me are a matter of fact with the Missus and I, and sometimes it is true!), and ego.
Still, not the machines fault, and I love that 3pt lever there.
