| I don't know much of tractors. 3 points, even less. Eventually I want to run 3 point implements on my 720 but I have no links(?). I've heard of category 0 but I have no idea what that means and I have no idea what links to look for. Do I just look for category 0 links and those will be correct? Same for implements. Do I look for something like a category 0 back blade?Also this tractor doesn't seem to have those rock shafts to raise and lower a 3 point hitch. It has a stubby hydraulic cylinder so I'm lost how a 3 point would even hook up. |

Sounds like you have the hydraulic cylinder and its attaching points which should also include the rock shaft - assuming you have the lift cables for the mower deck. The lift cables operate off the rear hydraulic cylinder. Yes, look for Category 0 implements. Generally, they use 5/8" diameter mounting pins. ------------- IB (restoring), MF GC1705, MF 2705E |

How it should look assembled minus the middle third link and sway chains (limit the side to side movement of the lift arms).

I have the rear cylinder and associated hydraulics and a piece that bolts to the rear axle to keep my rear PTO pump from spinning but that's it. This 720 most likely had a 3 point at one time but now has a backhoe mounted to it. I figure the 3 point gear was removed so the hoe could be installed. I don't have a rock shaft, nor does it look like I have anything for it to even mount to. |
