That is still ridiculous for that size machine.120 AUD is about 90 USD currently.
The market is obviously different over there. A guy charging those rates over here adjusted for currency value wouldn't get a single job. I can rent a D6 dozer for about $5000 a month and use it for 160 hours. The rental company obviously isn't loosing money, and they think it cost them less than $31 per hour to use their dozer.You can have your opinion. As I said I wouldn't do it for less. I used to get $60 an hour when I worked in an office without using machinery. If you take depreciation and running costs into true consideration then $120 is right and still making a small profit. Why else would you do it? If you want to work for nothing, go right ahead, but if you want to sit down and work out true running costs then you will see it is not ridiculous. Working for any less is. I have a friend who charges $600 an hour for a D6. He is swamped with work. A gardener with a push mower charges from $50 - $60 to do a city lawn. I can do a couple of acres in an hour easily and more if it is straight mowing. But, as I said, you can charge your ridiculously low rates and then find that you can't afford to replace your machine when the time comes. I don't really care.
Until you snag a stump or barbed wire buried or worse a survey pin or concrete stob.I can buy a ck30 without a loader for about $15000 maybe less for a 2wd. Add in $2000 for a cutter. Assuming the tractor last for 3000 hours ( I'd expect more ). That is about $6 dollars an hour operating cost. Add in diesel price current price is $1.70 per gallon, but we will figure 2.50 per gallon. Add in x for maintenance and repairs. You are now at about $15 per hour operating cost. It seems at 75 per hour you'd still be making 60 per hour. I'd be happy to ride around on a tractor for 60 per hour.
