For sloped property, choose a wide-stance compact tractor with 4WD, loaded rear tires, and ROPS with the seatbelt worn. There is no safe slope angle that applies to every tractor: stability depends on your rear track width and how high the centre of gravity sits, and raising a loader raises it. Penn State Extension's guidance is to keep the centre of gravity inside the stability baseline, the lines between the tire contact points. Carry the loader low and read the slope limits in your operator's manual.
Tractor rollovers are the leading cause of tractor fatalities, and almost all happen on slopes. The tractor itself matters less than your operating discipline, but a wide stance, low center of gravity, and ROPS dramatically widen the margin for error.
Heads up: this list is filtered on engine horsepower only. Drive type, track width, and roll-over protection aren't filter criteria here, so check each one on the model's spec sheet before you buy. ROPS with a seatbelt is a must on slopes.
Attachment classes covered on this page: rotary-cutter, rear-blade, box-blade, Listed engine HP, 22 to 60 HP, Tires, R4 industrial or R3 turf, loaded. Recommended models are filtered live from the tractor and implement records, so a newly verified model appears here automatically. The list is filtered only on the criteria this job requires: horsepower, loader capacity, hitch category, three-point lift or sub-compact class. Other figures in the spec grid describe the job and do not filter the list, so check each against the model's own spec sheet. Each figure comes from manufacturer documentation with its source and verification date on the record.
