I've been running a 59" Caroni rear discharge finish mower since last year. No issues, it does a good job. The remote lube feature make greasing the spindles an easy job.
Don't know what type of mower you are shopping for, but I've had my 73" Caroni flail for over a month now. Use it on my 5 acres of mostly bahia and other 'junk'. It does in one pass what my 6' LandPride RFM would need 2 passes to accomplish.
Have a Caroni 59" RFM that is almost 20 years old. For about half of that time it was taken car of fairly well. When we got a second tractor and mower deck 10 years ago the Caroni became the "beater" and it still works well even though it looks terrible now.
