My thought is (and maybe it's because I'm 53): Any job you're going to spend more than 10 minutes on ...have proper tools. Nothing frosts me more than, when I go to do the job, and the "tool" either doesn't work, needs it's own 'job' to make it capable to do the other job, or just does a halfass job. I got no time for that!
I would buy a commercial grade machine, not one at Lowes/Home Depot. Thicker gauge steel, little-to-no plastic parts, solid construction. Good commercial grade equipment, in my experience, lasts 3 to 4 times as long.
I've been partial to Husqvarna equipment most of my adult life. I'm sure Club Cadet and/or John Deere are similar. I have a 24 horse Kawasaki twin cylinder engine in my Husqvarna with a 54" mower deck. Of my 5 acres, probably 40% of it is mow'able. Some hills. When all is right, this tractor eats it up with no worries. (I do run rear tire chains year round - wet grass + slope = slipping).
After 8 years with this current mower, I am starting to do some significant repairs. Just rebuilt much of the mower deck (new spindles, pulleys, blades, belt) and I believe I will need to work on the Tuff Torq rear end soon. The mower deck parts were about $115 and I've read that the typical Tuff Torq parts are about $165. Oil changes etc. are negligible.
All that said, I paid about $2400 for mine 8 years ago, brandy-new. That may be more than what you were thinking, but, In My Humble Opinion, if you're going to buy something "cheap" for $900-$1200, it will start to fail in 1 to 2 years. You'll be working on it much of the time when you need to just get on it and go. (Again, just my humble opinion - I'm sure others may disagree).
Here's a consideration, if you've got a good mechanic's eye: Go on Craigslist and look for a used one that has been has been well kept and someone is moving and doesn't need, or bought a house that came with one. You obviously don't want to buy anyone's headache, and some might make up stories that "it was here when we bought the house" but if you have a good eye, go through it:
- Have the owner leave it cold for you to come start it. If it blows smoke, walk away.
- Check the structure of the body, where welds or 90-degree corners are, to see if metal is failing.
- Check the wear of overall "disposable" parts; pulleys/belts/deck/spindles
- Drive it around - how does it sound? Quiet/normal or oddly loud. Cut hard corners and 'feel' how it goes - does it seem to waver or is it solid/tight? Go up hills, does it keep it's speed. Back up, does it move properly?
- Check the oil on the dipstick. Golden brown? (good). Black? (eeeish!).
If you go through all of this, I would think you can find a GREAT machine for $500-$750. And I would think that money is FAR BETTER SPENT than similar for a brand new machine from Home Depot etc.
Good luck.
