Grapple became unattached.

[frj777]

New grapple became loose and fell off loader. Result is scraped up hose and grave concern. This is noticed when grapple is full open, against mechanical stops, and raking backwards.

Cam over levers are not as tight as on my other attachments. With levers completely closed this is a small gap at locking lug and grapple lower engagement.

Measuring the distance from the top engagement to bottom engagement shows about 5/16 longer on grapple than it is on Kubota bucket or Woods forks I have to compare. As well the flat plate portion of quick attach does not have much to engage on grapple, this may contribute to apparent loose figment as well.

Is there a standard for this type of mount?

Grapple is brand new, will be contacting manufacture this morning.

I’d say it’s likely you bent the mount not the grapple. Need more photos.

There is some adjustment of the wedge pins on the tractor side.

I have seen differences in the ssqa mounting by manufacturers.

My 30 year old skidsteer grapple fit the bobtach yoke on my old tractor fine. On the newer M59 there was a lot of play like you are describing. I made and welded in 3/8” plates on lower grapple side mounts.

Others said they have fixed similar issues.

Hope with good communication with the manufacturer this issue can be resolved to your satisfaction.

Good morning.

I believe nothing is bent. Removed grapple and installed pallet forks and bucket. Both work like always.

When latching levers there is no resistance. Spring tension should hold levers there is none. That being said levers did not open when grapple comes loose.

Was back raking manure out of barn when this occurred.

It’s fairly common for the Kubota SSQA mount to be undersized. You just need to add a shim at the top. It’s an easy fix.

I guess it works but I think you’d be better off shimming the top so you can maintain maximum pin engagement.

4570Man,

Thanks for your reply, how would you go about shimming top?

Take a piece of bar stock that’s as about an inch wide, as thick as the gap and as wide as the frame and weld or bolt it on the top edge.

When you shim the bottom you you run the shim past the pin to maintain pin engagement, also helps to reinforce the lower latch area, I prefer it over shimming the top.

I guess as long as you did a tight fitting job it would be a good solution.
