OTT Skid Steer Over Tire Tracks Sand Septic System

I have to install a raised filter bed septic system for my new home. I have access to a 2wd backhoe, mini ex, and a bobcat S150 skid steer. Would it be worth while to invest in a set of over tire tracks for the skid steer or will I need an actual tracked machine to get the job done. This will be my first raised septic system but I may do more if it goes well. I would appreciate any input on the OTT's or tips on the install of the system.
