I don't take delivery of my first tractor until next week (read newbie) but I keep coming across threads about someone knocking their FEL quick attach lever loose when operating the tractor. Like this one, "In my case I caught the quick attach handle on a limb using a grapple, lifted, grapple came loose on one side only and twisted the torque tube.

I saw this video of a grapple come off over a burn pit and dangle by the hydraulic lines! Check 44 seconds into this video!

Is this a rare enough event that I shouldn't worry about it? I know their is some dumb*** component on the operators part but I can see how using a grapple on branches could dislodge one of the levers. I could not find any proactive preventative measures. I think a metal or cable loop keeper would make it much less likely to have a branch unhook a QA lever. I don't think it would be too much of an inconvenience to have to use 2 hands to operate the lever like you do on a rolling door on the back of a box truck. The hook lever on those always has a lockable swing away keeper.
I know if my tractor was already delivered I would be out using it rather than bothering the OTT members on rare events but perhaps it will at least focus attention on the levers when operating to note if one gets dislodged. Perhaps wrap the handle with a contrasting color tape to really notice if its vertical rather than in its locked horizontal position.

Shame on me as it happened to me this time last year and I put no counter measure in to preventing it from happening again. I had a fine unlatch it, then I went to push a small tree maybe 1' in diameter into the woods that had fallen and my bucket came unlatched and it twisted the tube.

I was unable to bend it back, no amount of pulling or pushing even heated with a torch would work. Cut out tube adn welded in new one cost $120.00 to repair.

I need to come up with something happened again this week but I noticed the handle up and got off and locked it back down.

Dang! I guess it is worth worrying about!
Looking at your first pic I think we can come up with a ring or strap or something that will hold the lever to the bar. To keep them from sliding inward and off the lever we need a catch or a way to connect both sides together. Perhaps drill a hole through the end of the handle to attach a short chain with a hook on the other end. I think a bungee or strap might be vulnerable to normal operation. Any of you fabricators want to come up with an idea and start production?

Maybe the levers need adjusted. They should snap over center and takes a pretty good force to pop them back over center again to release.

True that. And I read threads of folks adjusting them and adding washers in such. Especially when QA was new. The problem is that this is happening with experienced operators as opposed to newbies like me. A branch forced into a tractor probably could have enough force to unlatch one of the levers even if it was adjusted where you had to use a breaker bar to get it loose.

Apparently the levers get knocked loose often, especially using a grapple.
Here are several thread with pics of carnage and some homemade solutions.

One guy welded a hook on the handle and using trucker bungee's. Another attached a steel ring with a short strap to go around the torque tube. I worry that a bungee would not keep it from getting dislodged by a branch. Most cases seem to be with grapples due to the type of work they are designed for.

With regards to force required to lock and unlock QA handles, my 3 year old can lock and unlock mine! She is a girl.......

Takes little force to move the handles in either direction.

Was looking at it today when Ella and I were washing Katie, need to come up with something to prevent premature movement of the handles.

In those thread I linked earlier they said that the weak tube was a fail safe designed to bend or break before worse damage happened to the loader. Take a look as may suggested putting a stronger tube. Other said it's supposed to fail like a fusible link. The trick is to find a way to keep the lever from coming unlatched. When I get my tractor I'm going to wrap the handle with tape barber pole style. With like 2 different colors of ugly tape where if one of those levers is vertical (unlatched) I'll notice. I'm also going to ratchet strap it to the tube or something until some redneck fabricator here comes up with a marketable solution. They will, I have faith in redneck engineering.

Creature Meadow, if a 3 year old can lock and unlock the levers they need adjusted. Inside the spring is a bolt with pins on each end. You can remove and shorten the spring to tighten the pressure.

Also, it is important to be sure when hooking up any attachment to double check to be sure the tractor plate is up against the implement plate. It is possible the THINK one has the pin in the slot because the lever went down, but the pin may have missed the mounting hole. This can mean one end is attached correctly and the other end is only hooked under the top angle.

D2Cat, Ella and I will be putting on a coat of wax today so while she is waxing on and waxing off I will adjust the tension on the QA lever.

Thank you for the tid bit of info, never even considered it.

With regards to it be seated well, I ensure that and I never ever never ever take off just the bucket as I do not have a grapple or forks so loader is either on or off.

Again thank you and I still need to come up with something to help keep it locked down. Things are bound to catch it from time to time especially when pushing and pulling vines and limbs.
