that unit should be capable of doing the job you describe. The more critical questions remaining are who will operate and maintain the machine. Machinery of this type does require a good amount of care - or expect some serious repair bills.

rcbe~~My husband and I will operate it and maintain it. I know about oiling the bearings after each mow and am willing to keep up maintanance myself and with occassional JD service. What else is special other than the regular oil change/tune up, etc? Thanks

take a few minutes - read thru the owners manual. You'll find a section on your tractor's maintenance that will lay it all out for you. Stick reasonably close to that and you should be fine.
Special? Keep the machine dry and clean. Use compressed air to blow off debris, etc. Don't use the garden hose. Check engine oil level before every use. Keep an eye out for tire pressures, loose fasteners. Checks all belts after every several cuttings for cuts/frays. Keep fuel can sealed/clean and only fresh fuel. Operate engine at full RPM's all the time while using it. Enjoy.

thank you.

Don't know if you made your purchase yet but I bought the 145 with cart a few weeks ago. In my opinion it's the best available for $2000. Looked seriously also at the Cub and Husqvarna. I've found the 145 to have a quiet smooth running engine and it seems to have plenty of power, the engine never seems strained. The only thing I don't like is the RIO but it's easy to bypass if it isn't needed.
