Working on a Sears 42" Mode 917.276181/ SN 042006D001017

The fuse located in the wiring harness has 15 amp rated fuse(blown). The parts listing in Sears Parts Direct indicates
the fuse rating should be 20 amp.

Looking for confirmation of what the amp rating please,

Look what I found in the owners manual about the fuse rating....30 amps....that seems high to me for a manually clutched PTO.

fyi,

In the back of the owners manual you should find a wiring diagram or schematic. That should have the proper fuse size noted. I think the 'text' portion of the owners manual may be more generic while the schematic will likely be more accurate. An opinion.
That said, unless you have things uncommon to a mower, I don't know what would need the extra amperage, except if your charging system is beefed up to handle an electric PTO, which your particular model does not have.
If you put an ammeter in series, such as across the fuse terminals, you can see the current flow and have an idea of whether a 20 or 30 is appropriate.

They are 20A but use a good quality fuse from a parts store. "White label" cheap bulk fuses are not reliable.

If you keep blowing a fuse when hot that is an early sign of the PTO clutch failing.

The most common problem that "pops" a fuse is jump starting off of a vehicle battery. The inrush of high Amperage from a vehicle battery will "pop" a fuse.
