I think it would really be accorrding to what you charge. Alot of upkeep on the equipment. RTR!
Not a huge amount of upkeep. Hit your grease points often and change the fluids and filters a couple times a year.
So I can offer bush hogging, land clearing including small trees, and light backhoe and loader services... Think that will keep me busy?
No way I could venture to guess the demand for these services in your area. I'll bet it'll depend on how you put yourself out there and your personal contacts. Throw in a ton truck w/dump bed and you are in business.
