Older bobcat pricing

[Grazzmazter]

My Dad has an older bobcat that is pretty slow, but runs and works like a champ. Should i fluxuate the pricing due to the older machine?

What do you guys get per hour on your machines for landscaping/hardacaping/excavating?

Ive charged 125.oo/Hr for moving snow, but never used one for summer use.

Thanks
