Unusual old mower deck

[cornus]

Can anyone identify this mower deck. It has two toothed drive belts which are tensioned by moving gearbox on mounting plate. No ID marks anywhere!

Looks to be a dedicated mulching deck. No cut-out for discharge that I can see. Cogged belts are common on decks with over lapping blades. The cogs are to keep it in time.

Discharge is across the back. There is a worn rubber deflector there. I don't think the blade actually overlap in their travel. I will check tomorrow. (the pulleys are not toothed)

When you say toothed do you mean like a timing belt or just a cogged belt. If the pulleys are small they most likely used a cogged belt as it will last longer.

Well, I was no help at all!

All replies appreciated. This one is a puzzle. Gearbox looks like a John Deer f725 but no other similarities. Heavy machine at 100kg plus. Looks like a substantial maker but nothing online at all like it

Yes, the belt cogs are probably for improved lifetime. The blades definitely do not overlap.
