Pony mounts
There are 2 triangular 3 bolt mounting flanges on the sides of the machine for mounting cultivators. They had a foot long piece of square tubing with a flange that bolted to each side of the machine.
There is a hole, about 1" diameter on the boss at the bottom of the clutch housing that is the main attachment point for the disk, and plow pulling arm.
There are bolt holes, tapped, in each of the planetary final drive housings to witch a Y shaped bracket made of 1/2 by 2 flat stock mounts for pushing the dozer blade. That is lifted by a Rube Goldberg designed mess of square stock that bolts to the right hand lifting arm on the front of the crossmember ahead of the transmission, with 1 5/8 and 1 1/2" bolt and a collar to make up for the taper of the lift arm. That contraption goes forward to a right angle bellcrank that mounts on the same point as the right side cultivator. Massey actually put a grease fitting on that.
The drawbar, 1'2 x 2" steel bolts to the final drive housing on each side of the tractor with 2 bolts. There are 2 or 3 holes for height adjustment.
Mott Belly mower, 4 foot, is pushed along the ground by a Y ahaped arm running foreward from the drawbar, and positioned laterally by a 3'4" rod running from the same attachment point the disk mounts to. When the mower is mounted, the right drive wheel has to be reversed to clear the push arm on the mower.
Every piece of steel used in any attachment is hot rolled steel, and stretches over time. The pin holes also ware out, and need to be rebuilt for proper lifting, cause if you don't, the wasted motion in worn pin holes will eliminate lift at the implement. The bellcrank assembly running across the front cross member, 1" square stock, sits in 2 flange bearings, and usually needs to be rebuilt because the holes are egg shaped and the part that rotates in the flange has a groove in it that needs to be rebuilt. Every dam bolt is 5/8 11 thread, and smart people replace the original bolts with hex heads to save knuckles. Massey got a lot of motion out of that little combination valve/cylinder. You also need to build up the pins in the yolk of the operating handle of that, or the valve quits working. Having a few spare gaskets for the valve body ain't a bad idea either, you can make your own from Velumoid, but they have to be thin, or the system won't work.
