Changing implements on his Case IH front-end loader used to be a frustrating and time consuming job for Dave McAdoo, Alvarado, Texas. So, he came up with a handy quick-tach system.
  He owns a Case IH MXM 130 tractor equipped with an LX series loader. "It's a really stout loader that works great. But the quick-tach system on it leaves a lot to be desired. Now it takes only about one minute to change implements, and I never have to leave the cab," says McAdoo.
  "You're supposed to be able to pull a æC' ring to disengage the bottom latch, then drop one implement, hook on to another and engage the bottom latch to it by tilting the loader. When it works, you only have to get out of the tractor cab once to change implements. But it never works because the pins in the latch get bent and then it won't trip to engage. And when the pins are straight, it trips before you can hook onto another implement. Either way, you have to get out of the cab twice."
  He tried several times to repair the system so it would work properly, but never was successful. "I started to rip it out and just use some long hitch pins, but decided to design a system that would latch and unlatch from the cab using tractor hydraulics."
  He installed a 1-in. bore by 6-in. stroke hydraulic cylinder on the loader's quick-tach frame. The cylinder is used to push and pull the pins from the center, where it's less likely they'll be damaged or bent.
  There wasn't enough room between the frame members to mount a cylinder for each pin, so he had to figure out how to use a single cylinder.
  "With the system I designed, the rod pushes one pin and the bottom end of the cylinder pushes the other pin. The rod pushes one pin to a stop that's located so that pin is in the engaged position. The cylinder isn't mounted, so as the rod extends further it pushes the cylinder backward and forces the other pin to engage.
  "When disengaging, the system works in reverse using a different set of stops. It's really important that the stops û there are four of them û are properly located and that all the holes line up so there's no binding."
  McAdoo bought all the hydraulic parts new, at a cost of about $250, "because most surplus cylinders on a farm are a lot bigger than the little one I had to use. The hoses were only -in. because there's no need for a lot of hydraulic capacity on this system. The small hoses and small cylinder made the system operate too fast. Fortunately, my tractor has a flow control on the hydraulic remotes, so I could turn it down to a reasonable speed."
  McAdoo has posted videos of his quick-tach system in action on his website.
