Motor, Speed and Incline
The 1750’s 4.25 HP motor gives more headroom for repeated sprints and climbs. Independent testers found it handled everything from recovery walks to marathon training, though they measured about a 4% speed variance that may need calibrating.
Testers found the Pro 9000’s 3.6 HP motor strong with smooth acceleration and liked its preset speed and incline shortcuts for hill repeats, but measured slow incline changes of about 46 seconds from 0 to 12%. Both top out at 12 mph and 12% incline; only the 1750 adds –3% decline.
Winner: NordicTrack Commercial 1750
Running Deck and Cushioning
The 1750’s 22 × 60-inch RunFlex deck is 2 inches wider than the Pro 9000’s 20 × 60-inch deck, which gives more room when you are moving fast, and testers found the 1750 very stable.
Independent testers found the Pro 9000 stable, but some describe its ProShox deck as too bouncy for runners who prefer a road-like feel while others found it firmer than earlier versions. Some testers also feel the 20-inch belt can be narrow for long strides.

Screen, Classes and Controls
Both have a 16-inch touchscreen that pivots for off-treadmill classes such as yoga and strength, and both rely on iFIT Pro for classes, SmartAdjust, ActivePulse heart rate training with a Bluetooth monitor and syncing with Strava, Garmin and Apple Health.
The Pro 9000 adds preset speed and incline shortcuts on the display, and owners praise its responsive controls. Some owners of the 1750 find its on-screen speed buttons unintuitive. Testers noted some glare on the Pro 9000’s screen.
Winner: ProForm Pro 9000
Footprint, Folding and Noise
The Pro 9000 needs about 73 × 35 inches of floor space and weighs about 218 lb; the 1750 needs about 77 × 37 inches and weighs about 266 lb. Both fold with assisted lowering, though one tester considered moving the Pro 9000 often unrealistic given its size, and another test team noted the assembled 1750 is too wide for standard doorways.
Owners describe both as quiet. One test team measured the 1750 at about 45 dB at walking pace and about 66 dB at 7.5 mph. Testers found the Pro 9000’s fan and speakers weak.
Winner: ProForm Pro 9000

Who Should Buy Each
Interval runners and heavier users: Choose the NordicTrack Commercial 1750 for a 4.25 HP motor, decline, a 22-inch deck and a 400-lb rating.

Consider Instead

If classes matter most, see our best treadmill with classes guide.
