I guess the biggest question is how much difference is there between a 317 and 318 frame?
I am a new owner of a JD 317 with a Johnson loader and a Cozy Cab with metal doors. The loader (needs hoses) and Cab (needs wiring update) are in reasonably decent shape. The tractor is well used and in need of major TLC or replacement. The guy I bought it from got it from his neighbor and "fixed it up" before selling it.
Before proceeding let me say that this is my first tractor - always wanted a small tractor with a loader and got this now that I'm retired. I paid $1600 for the outfit. I figured the cab and loader were worth that and the tractor came with the deal.
I'm considering replacing the tractor rather than repairing all the things that need to be done on this one. My question is whether I can put the loader on a 318? I don't know the model of loader other than it is a Johnson - part of the original tag/label is still attached and it says Johnson Manufacturing Co. on it.
The loader mounts to the front of the 317 via a bar assembly on the lower portion of the loader frame and spring loaded pins on hte top of the frame. The back part of the loader assemble sits and is bolted on an "assembly bracket" that mounts cross ways under the tractor frame in the location where the mower deck woud normally sit. There is no bracketing that goes to the rear axel. The loader bracket was not made for the 317 because it was all out of wack when I got it. I had to shorted the assembly by 1/2 inche and replace the front arms on the assembly to get it to fit correctly. It now mounts correctly.
