1864 GT54 PTO belt size?
 

What is the size of the PTO belt? I put my belt on from the 48" and it's awfully tight. So I'm thinking there's a bigger one for the larger pulley on the GT54 but I can't find a part number. The one I have for the GT48 to PTO pulley is a 754-3001.

I had t go up 1 size when I changed from the 48 to the 54. Pretty sure I used a B86 belt take your belt to TSC and match it up then get the next size larger. :beerchug:

That's what I was thinking of doing. But somehow when I size up belts I always end up with the wrong size and have to return it for another one.

Get 3 and take the 2 back that do not fit.

I run a B89 on the PTO and a A120 on the deck of an 1863 with a gt54.

There's defiantly a difference. even CC doesn't know from one manual to the next. The first pic has a C after the form #.
I'll find the numbers I use for each tomorrow. The 54" is longer even tho the manual shows the same.

That second image can't be right for this tractor. It says it's 114" for 954-3056. The now shredded belt I have was a 754-3001 which is 92". I'm thinking it should be 93" or 94".

The one I just put on my uncles 1863/54 was a B89. I used that belt deck combo on my1864 to test it out after replacing the deck bearings and blades. I think I have a B87 or 88 on my 1864/48.

I use a 754-3001 belt on the 1864 with 54" GT deck.

The TSC I just went to doesn't stock anything B87 B88 or B89. I guess I'm ordering one or driving way out of my way.
