I would agree from observing the various professionals work on my construction project, the skid-steers with tracks (track loaders) are the way to go for off-road use. There does not appear to be very many skid steer products in the "estate" or sub-compact range of size, cost, or heavy-dutiness.
The ASV comes close, but still it appears to be designed and marketed to the rental industry. Anything else?
I am working on putting the hydraulics and mount adapter on my CUT so I can take Skid-Steer and mini-loader attachments that are much easier to rent.
Also, the hydraulic drive on many of the attachments gives you more control and reverse! Where the PTO version of the same thing probably uses the PTO clutch which is either engaged or not and probably has no reverse.
So, in a perfect world, you would have four machines in your garage/shed:
1. A ZTR or front-mount mower dedicated for finish mowing. Might be useful for snowblowing as well if it has that option and a cab.
2. A smaller skid steer / track-loader with a bucket, forks, and maybe a 6-way mini dozer blade. Add a snow blade and delete the snowblower above if you like to plow instead of blow.
3. A mini track-hoe for any excavating.
4. A CUT for brush-cutting and any pulled-behind light-ground engaging and actual cultivating. Things like a harrow, rake, seeder, aerator come to mind.
Many "estate" size CUT's try and combine functions 1,2, and 4. Add a BH for 3. They tend to be a compromise on any given task, or optimized for tassks 1 or 4 and marginal on the others.
Machines like the John Deere 110 TLB try and combine functions 2,3, and 4 and give up on finish mowing, but since finish mowing is a primary chore for many "estate" owners, its a poor choice of machine for them.
Maybe a "kit" machine that can be configured for each use:
A power plant with hydraulics: 20, 50, or 100 HP options.
A cab and control system.
A swappable under-carriage: tracks, tracks with a rotating platform (like a mini-hoe), skid-wheels, or 4-wheel steering wheels.
Loader arms on the front with a skid-steer style quick attach.
A 3-point on the back.
A hard-mount backhoe on the front, but with the operator remaining in the main cab/seat so they can also drive around like a mini-track-hoe can.
All pieces quick-attach. Worst case configuration change on level, hard ground: 10 minutes.
