Wood LR72 gauge wheels

[oldnslo]

I recently purchased a used woods LR72 landscape rake and the gauge wheels are low. Does anyone know what the pressure should be in these wheels. I was some what surprised that they are even pneumatic.

TIA

Do they not specify inflation pressure specs on the tires?

I could not see any specs on the tires. Will have to check again I guess.
