Nobody has put it in writing yet. I want a machine that will mow the lawn well, move mountains of mulch quickly, brush hog the wilderness, plow snow fast and efficiently, change attachments in 15-30 seconds, etc... Nobody has shown me a machine that can do all of this nor has anyone put the actual dollar costs on a spreadsheet.
So far, my operating costs have been gas and oil, a hydraulic filter every 50 hours, five engine oil filters, two grease guns and two adjustable wrenches. Oh, and I blew a tire abusing the heck out of it twisting stumps out of the ground, and swapped out two caster wheels for solids. That's pretty much it. I use one gallon of fuel an hour. I have 300 hours, or 50 hours a years. If a CUT that could do what the PT425 does consumed half as much fuel, that would be about 25 gallons compared to my 50. Diesel is only a few cents cheaper than gas right now, and it was 45 cents more per gallon when I bought the PT425. The fuel costs would have been equal some years and, at best, a couple bucks more a year for me.
Oil changes... I use two quarts of Mobil1. That's 10 bucks, plus a filter, so say 15 bucks a year on oil changes. How much does an oil change cost on a CUT? 5 quarts or more = $25.00 plus filter. For the average homeowner, fuel costs and oil changes will not be that much money per year on either a CUT or a PT425.
As for the questions about what if I want to lift 1 more inch in the air... well, what if anyone wants to lift 1 more inch than their loader will? They can't do it either. I could ask questions about what if you want to mow a nice lawn with a 3000+ pound TLB and AG tires? Get off my lawn!
Lets say you want to mow your lawn and pull an aerator at the same time, as I was last Sunday, but you have your backhoe on. How are you going to accomplish that? Give us a time breakdown of how long it will take you to drop your backhoe, put on a mower, attach a pull behind implement (purchased not from Power Trac, by the way) then drop the mower and the pull behind implement and put on your backhoe again? That would take me about two minutes. Most CUT owners would not even attempt it because is is such a pain in the rear. PT owners do it any time they please. It saves us time, and time is money. Time is there to spend with the family. Any tool that gives me the opportunity to spend time with my family is priceless. I used to spend 2 to 2.5 hours a week on my lawn with my garden tractor. The PT has cut that time down to one hour a week, on average. For the same price, I could not get a CUT that would save me that amount of time.
A PT425 will run circles around any CUT of similar size in lawn mowing, brush hogging, material moving, snow plowing, post hole digging, etc... hands down. There simply is no other machine out there that can do the jobs that I need to do in the time that I have to do them that costs less to purchase and own than the PT425. If anyone has any actual dollar numbers to show me the light, please post them. I haven't seen one yet.
