An easy way to tell deck size on those, if all blades are the same length =42", if middle blade is short and outers long=48". Those spindles are greaseable and the bearing lash is adjustable. The original colors are beige hood, fenders, foot rests and kind of an off orange/yellowish for the frame. Hydrosatic tractors have a blue frame. '73 was the last year for starter/generator, they went direct start with internal 2 leg alternator in '74. I have two '74 models, one my Grandpa bought new and one I bought at an auction. They are tough tractors and had lots of implements available. They did not all come with a tiller, but seem to be found with one a lot. I have a mower, tiller, snow blade, snow blower, brinly hitch w/plow, and a 4K watt generator for mine. The tiller is a bear with manual lift. The only Achilles heal is the variable speed, they have to be disassembled to lube and nobody did that, both of mine are eliminated and I have each setup with a different pulley. One is fast for mowing and plowing, the other slow for tilling and snow blowing. The 16 Briggs is a hoss and fuel efficient if you keep the carb set right. Mine will just load the governor, then burn the belts off if you continue to crowd them, they don't stall. That engine is also governed between idle and full speed, so it will maintain whatever you set it at. Virtually no parts are available outside of standard bearings and engine parts. The engine is even getting harder to get parts for outside of ebay. Montgomery Ward was built by Gilson, who was bought by Lawn Boy, who was absorbed by Toro.
