1976 C120 drive belt tension

One thing I would add... I opted for a throttle pedal, which helps more than anything else. 

 

SAY... for sake of argument, that I had the tractor running at 3,600 rpm... and I pop the clutch. That thing is going to want to pick up and fly...

 

If I start off at a lower RPM... like 1,800-2,000 rpm, it acts very gentle.

 

Now, considering that at 3,600 rpm, I still have 4 grand more rpm left in the tank... let's just say... taking off at such an rpm as that could result in... great bodily harm... :laughing-rolling:

 

Again, this is about learning what the tractor likes, what it doesn't like, what surface you are driving on... things like that.

 

I guarantee, on my driveway, which is gravel, if I started off in 3,600 rpm, it would spin the tires before it did a wheelie. However, if I was on concrete... I would probably do a backflip...

 

Personally, I can't/don't buy OEM belts. I like the coating on the outside of the kevlar belts, as it allows the belt to slip on takeoff. Whereas, a belt such as @76-C120 has it may not slip very well, if not at all. 

 

If I went with a oem type belt on HellHorse, I probably wouldn't want to drive it... as it wouldn't be safe. :(

thanks for all the advise.  This tractor was my parents before it became mine.  I have been riding on this one for over 30 years, so yeah... I got plenty of experience with it, just not with a new belt and why I'm reaching out to you all for advise.  I totally agree that until that belt stretches, it is not for the faint of heart and inexperienced.  I have run it for all of 5 min to make sure it was changing gears and not grinding.  I use it every week to cut the lawn, and as you can see in the background of the one pic (the one with the belt cover) I have the snowblower as well (came in very handy last winter)  I'll run it around and use if for yard maintenance for now... once I finish replacing the tires.... yes. I still have the original 45 year old tires on it and they hold air.

Do you have a heat gun or hair dryer?

 

If so, while the tractor is running, blow hot air onto the belt, and see if it stretches out a little.

 

Old mechanic taught me that on the old style belts...

The reason I say that is... it is probably a little cold in New Jersey, and the belt may not stretch in these temperatures...

 

Hot air will speed this process. :thumbs:

And, I still say, taking it out for a good long drive would help immensely. ;)
