This belly mower came with the 1990 245 Case tractor I bought. I assume its the same age. I have not used the mower as my loader mounts interfere with the mounting.
By looking at the manual it looks like its all there. I have not measured the cutting width but believe its about 65"
Manual doesnt say what other models it fits but would think the 235, 245, 265 and 275 would be the same.
I have a mounting and parts manual to go with it.
Belts are there and look decent.
Blades are rusty but dont see any issues with them.
