How do I find out the Category my tractor falls into?

I have a Massey-Ferguson Super 65 Diesel tractor. Based on the serial number (CNM 670395) it should be a 1959 model.

I need to buy a rotary mower (gotta keep those pastures brushhogged) and need to know the 'category' so I can get the proper cutter for the tractor.

Also, how can I tell what the Horse Power of the tractor is?

And yes, I'm a somewhat novice to the world of tractors.

In theory any tractor can have any size of link pin but small link pins would be no use to a big tractor. The 65 had cat1 as standard originally then you could get a kit to convert it to Cat2. You will have to measure the diameter of the pins to see what Category your is and check with the list below.
Top/Lower Link Catagories
Top Link Lower Link
Cat 0 5/8" 5/8"
Cat 1 3/4" 7/8"
Cat 2 1" 1 1/8"
Cat 3 1 1/4" 1 7/16"

The 65 with the Diesel was just over 50hp.

I believe tractors above 50hp(drawbar, pto, or engine shaft?????) have Cat II pins. My Ford 4610 comes with both Cat I and Cat II capability and is rated at 46 HP PTO hp.

Texaspam, Massey made it pretty easy (unlike others) to know the H.P.: the model # is very close to the actual new H.P....thus your tractor is approx. 65 horse. As to the category, I think you mean what size pins your 3 pt hitch accepts: yours is at that cut off where it could be either Category 1 or 2. Measure the diameter of the hole at the end of your 3pt hitch arms and take that info to the dealer (I can't remember the actual sizes right now but Cat. 1 will be under 3/4" and Cat. 2 will be closer to 7/8" or an inch.
Either way, if your tractor has Cat. 2 holes, you can buy bushings to hook up a Cat. 1 implement (cheap). What size cutter do you plan on running? Your tractor should be able to handle even an 8" cutter in the right conditions, but you are going to find a HUGE price jump when you go from 6" up to 7" and beyond and may not be worth the $ for the little time you would save for trimming your own pasture.
Most 5' and 6' cutters come with Cat. 1 pins unless you request differently, but I would just get the bushings. DO NOT run a Cat. 1 pin in a Cat. 2 hole without the bushing as it will slop badly and cause lots of wear in the ball swivels at the ends of the 3pt arms. Hope this helped a little. Pete

Sorry Pete. It doesn't work that way once you get past the 35 which was about 34 pto horse power. The 50 was mechanically the same as the 35 and the same hp. The 65 gas was 46 pto hp. The early diesel was 48 and the late diesel was 50. They all came with cat. I pins.

I would bet yours is a Cat. 1 3 pt. hitch. The lower links use a 7/8" pin, the upper is 3/4.

For a Cat 2, it's a 1 1/8" lower and 1" upper.

Hitch is probably category two, but it could be category one or convertable. Check the hitch pin holes. Top link would be 3/4" for category 1, 1" for catgory 2. Lower link pins 7/8" for category 1, 1-1/8" for category 2. Some intermediate tractors have had cross drilled holes with both sizes. Every place that carries hitch pins has adapter sleeves so category 1 implements fit a category 2 tractor. My JD 4020 has changeable antisway blocks that when turned for category 1 allow the lower arms to get close enough for category 1.

65 is more than a 35, likely 50 hp. I don't have data. 165 was about 50 hp. 65 won't be as quite as large an engine.

Google it and you should come up with these specifications on line somewhere if not on these yt pages.
