Marking high & lows while mowing/brushcutting

[Wormwood]

Is there any product that you can attach to a tractor to mark places in a field or yard? I'm using a marker paint extension wand to mark places I need to fill in with dirt or scrap off the top as I run over them with the tractor.

I was thinking of something attached behind left or right rear wheel aimed down at the grass. Bump a momentary switch & it sprays the ground for you. It would allow me to keep both hands on the wheel and not have to hold the extension wand constantly.

Thanks,
Wormwood

Foam row markers are as close as I've seen advertised. You might rig something with a can of shaving cream. 2.5 Gallon Turf Foam Marker | PaulB Parts - Ag, Industrial, and Mechanical Supply

A thought brought on by stuck motors post. How about a tank sprayer with a dye. Rig up some sort of valve for under foot. Maybe the sprayer trigger then hose to ground.
