G1800 deck height gage

[jas67]

Is the G1800 supposed to have a mower-deck height gage?

According to:
Specifications: KUBOTA LAWN & GARDEN TRACTOR Model:G1800/G1900

It is supposed to have a dial gage. My G1800 must be missing this gage?
Can someone post a picture of the gage?

Where can I get one?

Thanks,
