When I got my 84" rake,, I thought it was for my 60HP tractor!!,,,,
It turns out,, my 17HP tractor handles it just fine,,,
I move piles of leaves and sticks with this JD and rake that would overflow an 8' bed pickup,,,
The gauge wheels double the usefulness of the rake.
You can get the gauge wheel kits on eBay for a couple hundred dollars.
