Hello and welcome to the group...
If it is this Saber and item #6 in this drawing it's 1/4 X 1/4 -12...
John Deere - Parts Catalog
It this does not look right put your model number in the box and drill down to the trans/ axle parts diagram... after you select the part into your 'cart' you can then go to your cart and it will have a more complete description... Hope this helps, and you get your 'low' hour JD going soon... :smile:KennyV
