New to tractors but it seems that every manufacturer had different idea on how to connect everything on a 3PH.... Probably to keep you within their proprietary system... MY GC1715 uses a CAT 1 3PH... That said, I decided to go with a CAT 1 quick hitch by Agri Ease, connected up in about 20 minutes including leveling adjustments.... Looking at what the attachment industry is putting out there then is not to much that states "quick hitch compatible" and there is thousands of legacy attachments out there the fit close but no guarantee without a lot futzing around....... And the few items that do, don't necessarily fit my needs... I believe it comes down to about two things, 1> Is attachment appropriate to my machine for job at hand, 2> How can I "FIX" manufactures short cummings on design (generic) for connection to "hitch".....
Only other option is buy a complete "system" from single manufacturer off showroom floor already fitted to tractor, meaning basic tractor, FEL, rear scraper (box?), rear rake, rotary mower, or mid mount and backhoe if needed...... Mix and match still will require owner to adapt whatever necessary to make desired attachment work properly by studying its design and setting up proper geometry of attachment PROVIDING attachment is proper sized to tractor...
Problem is not going away till "quick hitch" compatible become industry standard, and all the legacy attachment fade away which probably isn't going to happen soon if ever...
