Hey Solitary Man,

What Grapple do you have?

EA root grapple

My EA Wicked grapple goes on and comes off a LOT easier than my other SQAs, though, despite a lot of heavy action it has never come loose. I seem to recall that Kioti also had some advisory out around the time that I got my Kioti [2016] (but it wasn't applicable for my tractor). I suspect that manufacturers are little loose on their interpretation of the specs: and aftermarket folks likewise- add the two together and things can be a bit off.

The Kioti bucket fit perfect. The Kioti forks and RK Granite grapple were both really tight to the point that the left pin wouldn't fully engage, and the right one took me standing on the lever to get it to go over center. Had to grind on the left pin to get them to fit, and it still take a good bit of upper body force to get them to go.

That sounds like something is bent, flexing or out of spec. You shouldn't have to grind on the wedge pin. The pin is wedged to compensate for variations in attachments. Fix the attachment, not the pin.

On my new grapple the pin is spring loaded and adjustable. I can adjust the tension on the lever from zero to stand-on force for closing or going over center. Once the pin is engaged, it shouldn't be popping out.

On my Kubota B26TLB, sometimes I need to shake the bucket before closing the levers. Found this helps prior to locking in. The forks don't seem to need shaking. Jon

I would agree.

On my Kioti, at least, there are no adjustments for the pins that I can figure. The pin was just a touch too long and the wedge angle was just a touch outta spec. I'm sure both dimensions were within tolerance but the pin was just a hair off compared to the other (I actually mic'd both, and you could see the pin just barely engaging at the tip) so I decided to grind the pin down so I didn't have to adjust every attachment to the pin.

Smoke with manufacture and they are sending a shims for bottom of QA. It will be up to me to weld…they did credit my card $ to allow for me to hire a welder. All in all not unreasonable.

I expect this will resolve my problems.

Grapple is a EA Wicked 60 inch Root Grapple.

 

[frj777]

Thinking of installing shims by drilling, countersinking shim and tapping grapple to fit and test…if this solves problem I will have welded. Thinking of a hardened, socket drive, flat head machine screw, 1/4-20.

Does this seem reasonable?

Thanks for all the response and suggestions. This may be a fairly common problem, buy it is new to me.

Yes, I think it would work. make sure that the latch mechanism still goes over center.
And I don't think it would need to be welded.

Your idea using flat head machine screws should work fine. Be nice to fit so the wedge pin contacts both the OEM plate and shim.

Really like our 54” wicked grapple. Glad the manufacturer step up with a solution to help.
