Well...you need to do ALL the math...
Using my girl friend's farm as an example. before me she hired out EVERYTHING. That meant snow plowing, brush hogging 20 acres of horse pasture, and some other odd jobs as needed.
So I bought a tractor for $22,500. It need oil/filters and of course, fuel. Figure that it's $4/hour for fuel/oil/filters.
Now my time has value..if I'm not doing this I could be making what? $18/hour, perhaps more. So the 30 hours it takes to hog all the fields $120 in consumables and 450ish in my time. She'd pay $700 ish for this, 3-4 times a year.
Plowing the drive was $75 typically. Takes me 1/2 hour or so, $11.
The bonus is all the other stuff we can do - pull fence posts, put in posts, trim tall trees, move brush piles, and on and on. things we'd pay for or more likely, just not do at all - or worse, do by hand! (post hols by hand..yuk)
Add in the cost of implements...bought most used, but $2500 ish is a guess.
How to put a "value" on having the tractor there...we're putting in a riding arena and using the scraped up dirt and clay to fill in low spots in /round the barn, re-sloped a hill that was too steep to mow on a tractor, move manure weekly instead of waiting for the brush hog guy to come with his tractor.
And also figure in the residual value of the tractor and implements when you go to sell them - so you get a net cost.
So far this year i've put 114 hours on the tractor in 3 months...and an easy 40 more to go - and i got it in early june...so 250 hours a year no problem, 2500 over 10 years. What is a 10 year old worth? $8k maybe more.
So 14,000 plus implenets..$2000 resale - 25k in, 16k out, 9k cost for 2500 hours, under $4/hour. Fuel/maint another $4, so $8/hour, plus your time (rent vs hire it out completely) if you out a value on it.
Renting a mini ex here for 4 hours is $220 (as of friday..I need to dig up something next week) or $320 for a day - so $32/hour (figure you'd run it 10 hours) plus fuel. Usually delivery and pickup is included.
The backhoe for my tractor is $7500..plus storage, finance fees perhaps..resale is what, $4k maybe. So $3500 to own it for 10 years, $350 a year, plus the hourly fuel of course - if I use it more than 10 hours a year it's probably worth owning it.
Not sure if you have looked at a bit of math to put it in perspective. Let痴 say it takes you 3 hours to dig a 6 stump on a SCUT W/BH that costs $10k. Let痴 assume to usable life is 3000 hrs. That is $3.33 per hour not including maintenance. So we have a cost of $10 to dig each stump. That is $500 plus 150 hours of your time. Rent a good sized mini ex and you can finish it in a weekend for less money. These numbers may vary, this is just an example. Please plug in your actual numbers to get a more accurate estimate.
Now if you don稚 mind 500 hours of play time on the SCUT, then you are good to go!
I have been struggling with the same type questions for my property and trying to do what makes the most sense financially and productively.
Maybe it would be best to rent a SCUT with BH and see how it works out. That $250 might answer a bunch of questions. I did and it helped a lot.
