The 3-ton sweet spot — septic beds, landscaping, waterlines.

The KX033-4 digs to about 10'6", which covers septic bed installs, waterlines, and most foundation and drainage work a small excavation crew takes on.
At 3.3 tons it's big enough to move real volume on a paying job, but still compact enough to trailer behind a properly equipped truck without stepping up to a dedicated equipment hauler. That's why I'd put it on a landscaping trailer as a contractor's first machine.
Conventional tail swing — the counterweight extends a bit past the tracks when it rotates, so you want normal working clearance around it. For jobs tight to a foundation or fence line, the similarly sized U35 with tight tail swing would be the better fit.
It runs standard buckets sized to its class along with a hydraulic thumb for handling rock, roots, and debris, which is common for septic and landscaping work. I can go through specific options once I know the jobs you're running.
Both are offered. If it's going to run through a Grey-Bruce winter or you want weather protection for full days on the machine, the cab is worth the difference; for seasonal or occasional use, canopy keeps the cost down.
