OP,
What’s your budget?
As others have mentioned, if you’re concerned about slopes, take a look at PowerTrac as you also look at other machines, just to get an idea of what they offer. They make several different sizes of machines, and two slope mowers that are rated at 40 and 45 degrees (45 degrees = 100% slope!).
The nice thing about the PowerTrac design is that not only is it a mower, but it is a front end loader/tool carrier. Everything is mounted out front where you can see it. They have a great quick attach system that allows you to swap non-powered implements in 15 seconds without getting off the seat. Powered implements requires the operator to get off the seat and change a few hydraulic hoses, so that adds a few seconds. All powered implements are powered by hydraulics, not PTO shafts.
There are over 40 attachments available, from mower, brush cutters, stump grinders, snow removal equipment, several buckets, grapples, 4-in-1 buckets, brooms, forks, etc.
Anyhow, if you want a multi-purpose machine, I think the PT design is better than the Ventrac design. I think the Ventrac is a better mower, but the PT is a better all around machine, especially with the forks and bucket choices. Ventrac loaders (on select models) are kinda an afterthought.
The Toolcats are pretty sweet as well. CAB!
Compact telehandlers, too.
Anyhow, come up with a task list, find what machines would do those tasks well, and then try and correlate the right machine(s) with your budget.
