40D Modified Steps

[Tractorganic]

I'm having knee trouble and this latest bout is a direct result of climbing up and down off TC40D tractor and backhoe. Did you know that a mere 20 cycles to and from pickup site and placement site (3" crush stone for bank stabilization not placeable with FEL bucket) results in 160 mount/dismounts from tractor and hoe?
Anyway stepping up onto the tractor with the factory steps is a stretch to get up to the lower step, and then to the upper. Has anyone heard of a replacement step with a lower reaching bottom rung and an additional rung near top or a mod' of the factory steps?
I won't even begin to approach problems with the backhoe's mini step yet.

Just for ducks, look in the RV catalogs as they offer fold-up/retractable metal steps.
