Can you use the old piece of rope and tape measure trick to find an approximate length as starters?

You have the old belt there, take it to a belt place. They measure the back around for the length, you could also. Then figure out the series by its width, consider it likely is worn a bit narrow.

Or check here, I’m sure one of the models will be an obvious match for yours.

Just take the old belt in to a good parts supply for trucks or other bigger equipment and they can fix you right up. New belt or order a new one for you. Big belts are not going to be cheap .

Im pretty sure that says Gates Power II C51. Any good parts store can get it.

Looks a bit different

I agree. Take the old belt with you and match up a new belt.

DO NOT let them get you all turned around, and convince you that the belt has "stretched." It's pure baloney. Belts stretch a fraction of an inch at most, but these belt places will try to convince you that you need a 2" shorter belt. That is pretty much a guarantee that you will be making another trip to get the longer belt. Get the belt that matches up the best with your old belt.

I know it's an old post from 12 months ago, but it might help someone else in the future.
This belt is clearly a Gates Hi-Power II Belt (we can see ''...wer II'' followed by ''C51'', so this belt is a : Gates Hi-Power II C51
C section V-belt means 7/8" Top Width and 17/32" Height
C51 means 55.0" Belt Outside Circumference (because 51 means the inside diameter, and for some strange reason, they decided they would use the ID for the C type belt identification! Anyways, Mott mowers came in different pulley combinations using 8,0'', 8,5'' and 8,75'' diameters.
The newer models (62, 74 and 88) used a 8,5'' and 8,75'' pulleys with belt #100706, this one a C54 with diameter of 58,0''
The older models (60 and 72 models) had two same 8,0'' pulleys and used belt #102631 which is a C50 with diameter of 54,0''.
There were also options like higher speed and reversed rotation that used other rare pulley combos, with a special 7,5'' driven pulley, and all those variants used one of five belts between 54'' and 58'' (C50-C54).
So by looking at the first picture at the beginning of this post, it's obviously an old Mott 72 model, just by its 3pt A-frame and also the U-shaped roller guard we can see at the bottom of the image. So that belt would normally be a 54'' belt C50. BUT... This mower has something different, an option so rare that this is the second time I actually see one like this! This is a ''REVERSED ROTATION'' mower! We can see here that the shaft pulleys and belt are on the right side of the mower instead of the left, so the flipped gearbox's driving shaft is now turning backwards. I would be curious to watch how such a mower performs! But I'm not sure about being bombarded by some high speed flying debris burping out front by the mower's blades! Like I just said, these older models (60 and 72) can be identified by their thick, straight 3 pt frame arms, compared to the Y-shaped ones on the recent models. The old models also have those thick cast iron roller shaft nut guards on each side, and this also means that the mower has the discontinued threaded tie-rod roller shaft system, with all the obsolete parts and bearings that aren't available anymore...
****** ATTENTION!!! ATTENTION!!! USEFUL TIP ALERT! ****************************************************************************************
So useful, it might make you save big money! So here it goes... When one day, these old roller bearings eventually fail and die, too many people just listen and fall for what bull crap they are being told by the ''company'', telling them they must invest $1500 and upgrade to the complete ''new style'' roller shaft kit, and ditch their whole roller shaft assembly, just because those two weird, unique and expensive Sealmaster bearings are now phased out and gone forever, which is just crazy and complete nonsense! These two large bearings can be easily replaced by using four cheap $5 bearings, doubling them on each side to support the load like the old ones. I did this almost 20 years ago, and they're still doing their job, which is not bad at all for that $20 investment, better deal than the $1500 option. The ones I used were very common 3/4 ID bearings that can be found everywhere. You just need four 6204-2RS, and It's such an easy job changing them with maybe some little grinding and fitting some kind of spacer or washer, but still an easy task that can be done with the eyes closed. Who cares if they last 5 years instead of 20 years. It's just a roller, after all! Just don't let those pricks grab your hard-earned money for two simple bearings! By the way, you can also find cheaper cutter-shaft bearings+housings replacements, instead of the expensive original EOM ones, once you searched hard enough to finally figure out the specs, by decrypting those well-kept secret part numbers, I think something like UCF206-19 might fit... For the cutter-shaft, I recommend to going with good quality bearings for this demanding task, because the cheaper ones from ''Ghina'' won't last very long. But with top brand bearings , they will hold up for at least 3...4 years, maybe more, for just a fraction, 10% of the price... You do the math, and you decide. It's your money, not mine! We all know that the $25 version won't last as long as an indestructible top quality $230 Sealmaster, bearings that were built to last forever. If I had a mowing company with full-time contracts at cleaning highways and golf courses, going with Sealmaster would be a no-brainer. But for a few occasional cuts like we do... I'm always willing to take a chance when it comes to save a buck. Sometimes you win some, sometimes you lose... Isn't that's what life all about? I did try lots of ideas in the past and some that didn't work as good as expected, I call that experience! That's why you can trust me on what I'm saying here. That's the way I've been operating this for quite a while, and it works, period!
One other last little tip to make you save again a few more bucks, something I have doing for years, with more than a few cars... In my 88 Mustang GT, I found out many years ago that the serpentine belt 1/2 inch smaller than mine was like $50 less expensive than the real one, all because this belt was also the same belt as in a Toyota or Honda popular model! The tensioner spring is just slightly a little tighter and everything runs fine. So when possible, if you can swap, let's say that $90.00 54'' belt for the 53'' or 55'' one instead, and it happens to be a massed produced belt for some reason... it may cost only $12 for the same, but 1'' shorter belt. So if it fits and everything still works as expected... Then you've just got another $78 to put in your piggy bank! Now, you can go spend all that unexpected money on something useful that you really need... like a truckload of beer! Because once you finished mowing that neat looking lawn of yours, with your tuned up Mott mower you maintained to required operating condition to work like a charm, all because you pulled this off, and you even saved some money!
It's now time to just sit down, crack open a nice, well deserved cold one, and enjoy life for a change!
So, until then... Keep on mowing!
P.S.: all bearing numbers given here are applicable to the models 60 and 72 only!

I uploaded The Mott 60 72 manual and parts list 4 times, but it never appears anywhere once it's uploaded!
WTF?

If using Android phone look for files or file manager. Then downloads. No guarantees.

No! I don't want to download... I wanted to ''upload'' a small 1,8 MB pdf file from my PC ! It never worked, so I converted in multiple jpg files and it worked. Problem solved! Too bad the pdf files are blocked, this is what the pdf format was invented for...
