I'm still confused about why Millonzi isn't using industry provided specs to build the non Universal QA mounts. Doesn't JD publish the specific dimensions necessary to fit their pin mount system? I have never asked for it for one of my tractors but I did ask Woods for the information on my backhoe and received a professional engineering drawing in PDF format that showed to a hundreth of an inch exactly what the dimensions are. Do the tractor manufacturers not make such information public or are they unwilling to give it out if specifically asked. Having a FEL model number and serial number should be perfectly adequate information (IMO) for a company like Millonzi to then get any further information they need to do the custom fabrication.
Maybe they do have the precise dimensions and the problem is on the fabrication side of the process. I don't know if Millonzi is using a CAD type system for producing these mounts but if not then perhaps they should or at least should up the standards for precision. Don't they QC their fabrications? If we were talking about a mount for an out of production Belarus tractor I could see there would be problems but I don't understand why they should have any trouble at all with current or recent models from JD, Kubota, NH, MF, Kioti, Mahindra etc. I have not seen any complaints about WRLong grapples or other brands. Not sure if those are simply mostly QA mounts but I know WRLong and ATI have tractor specific mounts.
Bottom line from my perspective is that this is the type of thing that should not be happening and should not require the major hassle of sending grapples back and forth across the country to fix. Millonzi has always been very responsive but it would be even better if they just got it right to begin with.
