I am a Starbucks Coffee Manager "refugee" and am now on the verge on starting up my own lawn business. I have the opportunity to "test the waters" by using my neighbors Riding Mower + trailer (he's taking a break from the business) ... Its almost new (20 hours of usage) and is small to med. in size - he paid around $3800... What is a fair price to pay him for 'renting' his mower ? Should I pay him a few $ by the hour since the mower display hours used ? THX !!!
