Hi Bob! Welcome! There were some telltale differences when the 640 and 641 tractors were new. After 50 plus years it's hard to tell how they've been amended. In the beginning the 640's tin would all have been grey, whereas the 641's hood would have been red. The 41's fenders and grill were grey.

The 640 would have had an ammeter where the 641 would have had an idiot lite for the charging system and a fuel gauge.
The 640 would have had fenders that swept out over the top of the tires, whereas the 641 would have had clamshell fenders that only shielded the inside of the tires.

Other than that some production date codes may pin it down. However, the best way would be to get through the paint and read the model and serial number.

You are correct onthe PTO. None of the 4 speed models had live PTO in that era.

Wow! Thanks for the quick response from all of you!

Vito - the hood emblem does say 600.

HCooke - The 601 you show looks almost identical to mine - but the color scheme has been slightly changed. The brake locking scheme looks familiar, but I'll have to look again.
Larry NCKS - I think some of the gauges have been swapped, so I'm not sure they are original. It appears that there is a red warning light on the lower right of the dash board. My tractor has been converted to a 3-wire alternator, but only wired a a single-wire alternator. I'll be fixing that! Also, the rear fenders are like clamshells.
