I have a Kubota MX 5400 with the Kubota quick attach. When I pick up grapple the lip on the bolt on side plates seem to be on a greater angle than any of my other front attachments. I'm only able to get about a half (1/2) inch of the plate into the lip. When I pick the grapple up and tilt back I am able to lock the bottom pins but the plate face is not flat with the quick attach plate face, it needs to slide up more into the lip and off of welds by locking pin holes on bottom. It seems it has to move up about a half inch into top lip, this would let bottom to sit flat above welds by locking pin bottom angle holes. The unit is shipped with flat face hydrolic cupplings which we were made aware of from Titan when we ordered them and we would need to switch them to Agriculture because they couldn't switch them for us. After going to 3 different hydrolic suppliers, they are unable to match the ends to the reducer threads that are on the grapple because the threads on the fittings that Titan uses seem to be different. After multiple phone calls and also email with detailed description of the problem along with pictures, we still have not received a response. It has only been a week but it is still a week that we were not able to use it as firewood season for us has kicked off. Hopefully Titan can resolve this and we can updated our review to a 5 because it looks very well built and we are very excited to have it.
