For the past ~10 years I have been using my Ford 1620 HST 4x4 with 60" 914 deck to mow about 7 acres. I'm at the point now where I don't look forward to mowing due to many mower deck breakdowns (tractor is great) along with the the time required to mow all 7 acres. It basically kills one whole day of my weekend. I think the top speed of the 1620 in MED gear (fastest I can go due to blade speed and cutting) is something like 1.5 mph.
I have been hesitant to get a zero turn due to the fact I have a decent strech of mowing along ditches & pond banks (~1200ft of pond banks, ~ 1000ft of ditches), where sometimes it can be a bit wet. I have never gotten my 1620 stuck to the point I needed another piece of equipment to pull it out. The rest of the mowing is very flat.
I have been looking at thie Ferris mower:
Ferris 5902073
I assume my cutting time will decrease, but it also seems like I am going to not be able to cut some areas, especially on the steep ditches?
I have been in the same boat with my property. Depending on how much I choose to cut, I can "mow" an average of 5 acres but sometimes it's more if I choose to trim up the fields. I have a 2000 foot driveway with ditches on both sides, I also have a pond. I've been cutting it with a utility tractor with a 6' finish mower and a loader that I leave on because it's a pain to take on and off. I average 2 days a week, about 9- 10 hours to get it done. The tractor still beats me, is a pain to maneuver around obstacles and trees.
I originally was looking for a good rider, like the John Deere X739. I briefly thought of a zero, but heard of control issues, quality etc.
I saw an ad for Hustler talking about their stability on hills. I went and talked to the guy, test drove it, and he brought it to my place and mowed around the pond and all my spots that concern me.
Zero turns need width and weight for stability, and decent tires. I won't lie, you can slide on wet ground. You can also slide on very dry grass. There is a learning curve of what to do and not do, not being stupid, knowing your limits etc. I have a heightened sense of fear as I had a rider flip on me, so I get overly cautious. Often, more power is the way to go. I was uneasy around the pond, the salesman came out and demonstrated again that going faster gives me more control.
The simple solution is using your tractor on the areas that you're afraid of, use the zero on the rest. Depending on the mower, if the deck is attached more to one side than the other, you can keep your wheels out of trouble areas.
I looked at Ferris, it was expensive as was Kubota. Get a commercial quality mower with good commercial hydros. Look for a heavy machine, mine weighs about 1400 pounds. I have a simple seat, but I did add flex forks, I can't complain about the ride. I've had my Hustler X-One-i for 11 years, no issues other than oil and filters. I now get all my mowing done in 3.5 hours, maybe 4 if I change patterns. It's a beast and I've done a bit of bush hogging with it as well
