I am not familiar with the internal workings of Allen Scythe but I do have an instruction manual with parts list in my literature collection. Looking at the illustration on page 25 it would appear the clutch mechanism on the model T is inside the gearbox, see photo below.
If you send me a personal message with your e mail address I can email the full manual to you.

There is a topic in the Help and Information section of the forum with advice about how to resize and add photos.

Later machines had a simple plate which chain runs over to adjust tension, (part number MT338B in series 3 manual) . If slack is more than 1/2″ then try taking out one link if there is no adjuster.

Have you tried bokfinder.com ?

5.5 cwt (280 Kgs) or 6 cwt (305 Kgs) if it has the Douglas engine. I am not sure if this is includes the plough or is just the bare tractor.

Seems like a lot of effort when repairing the gearbox could be easier. The gearbox is the same as a BMB Plowmate. Electrification would have its own problems, size and weight of battery to give a reasonable run time for example.

If it was not half way around the world from me I would be interested to add it to my collection. I know there is some interest in collecting old rotavators etc in Australia, we have 3 club members, all in Victoria. If you plan to sell the machine options would include online auction such as ebay or a mainstream tractor magazine that has similar adverts.

The recommended grease for chain lubrication is Castrolease Medium.The chain should have 1/2″ of movement on top run when correctly adjusted.
It is worth noting that the main gearbox should use a straight gear oil not EP90. Castrol D or equivalent SAE140 gear oil is recommended. I use Morris oils AG140 Classic Gear Oil. Castrol XL SAE 30 for the engine, Morris Oils Golden Film SAE30 Classic motor oil is what I use.
If you drop me an email with your email address I can send you a copy of the machine manual.

Is there an overload clutch that needs adjusting?

Any photographs of tractor and engine, may help with sourcing information.

I suspect the only source of a worm gear will be from a scrap machine. Having one made will be extremely expensive.

Yes Automower winches were used for power line construction.
