I agree 100%, I am on 12 acres and my tractor collection would seem way overkill too, but I sure have a lot of fun playing on my tractors and with a large pond and lots of trees and lots of yard that I like to keep mowed and trimmed up like a golf course, I manage to find projects that keep all of them in use quite regularly, I think in the past 2-3 years both on tractors that I have today and some that I traded off to get up to the tractors that I have today, I have logged at least 2000 hours of tractor seat time in that time.As stated above its your money and do as you wish. I have an X758, 2038R and a 4066R on the way with 3 acres. However I take care of an additional 8 or so acres of adjoining neighboring lots and am on the hunt for a 20+ acre camping property. Still wayyy overkill but these tractors are my hobby. Gave up the race cars for it and I thoroughly enjoy all time spent on them, in them, tinkering with them etc. That being said, how hilly is your property?. The X758 is an absolute beast on hills, 20 degrees plus side hilling. However as mentioned a loader is an awesome tool you will find alot of used for. If the ropes doesn't bother you and your lawn isn't crazy hilly, I say go for the 1025 👍
I use to be big into ATVs for over a decade, we would travel long distances and go on big group rides, at one point got into sand drags for a few years as well, also had boats, and other toys over the years. Now days I am back to my roots playing on my big green tractors. When I was younger growing up we called it work. LOL
The tractors have replaced pretty much all my other hobbies these days.
As to the OPs question, I think if your mowing some steep banks, ditches, have a lot of trees to mow around, then the X758 probably is the best option. Those steep ditch banks Arsenix200 was describing using his X758, is the exact same reason I bought my X758.
It is by far most capable mower for challenging or difficult terrain.
I had a Diesel Z9 for a few months, and constantly got it stuck and could not hold a ditch bank at all, just horrible mower for my application, it soon got traded for the X758 I still own and love today.
On my X758, I have versa turf radial tires, the rears are loaded with ballast, I have suitcase weights on the front to help keep nose planed on steep banks. I added a 3pt hitch, which I would probably not do again.
I had to bypass the seat safety because you can actually set up on the side of the seat on really steep slopes and still hold it solid and stable as can be.
If your on more flat ground, then sure the 1025R would probably be the better choice given all the optional equipment your putting on that X758. It likely might actually be cheaper to do those on the 1025R then the X758.
The rear 3pt is not cheap, and then add rear PTO also expensive add to a X758. Also the rear 3pt has a higher lift capacity on the 1025R then the X758. Both have the same engines and should offer first class cut quality for mowing.
There was mention of rear bagger. You can opt for the TKV20 which is a far superior bagger system compared to the MSC. That alone provided the OPs terrain is not needing the Billy goat capability of the X758, I would for sure go with the 1025R just so I could also go with the TKV20 bagger system. I used that MSC setup for years on my X740 and now that I have the TKV20 on my 2025R, there is no way I would ever go back to the MSC setup.
