Engine and Power

The Predator 9000 offers more starting and running power than the Predator 8750.

Predator Generator 9000 vs 8750 Engine and Power
A larger fuel tank and slightly higher fuel consumption allows the Predator 9000 generator to provide more power.

The same 420cc (13 hp) air-cooled OHV engine can be found on the Predator 9000 and 8750 generators. However, the Predator 9000 sports a larger fuel tank and slightly increased fuel consumption to allow it to provide a higher starting wattage of 9,000 W and running wattage of 7,250 W compared to the Predator 8750’s 8,750 W and 7,000 W respectively.

The Predator 9000 carries an 8-gallon gasoline tank while the Predator 8750 only has room for 6.6 gallons, so you can get a longer run time on the former, too. At 50% load, the Predator 9000 can deliver 120/240 V for up to 13 hours while the Predator 8750 lasts 12 hours. That does mean that you’ll need more fuel for the Predator 9000 since it consumes unleaded gasoline at a rate of 0.62 gallons per hour to the 0.55 gallons per hour of the Predator 8750.

Both Predator 9000 and 8750 have fuel gauges so you can check how much fuel is left in the tank. They also have low oil indicators and a low oil shutdown feature for safe usage.

Portability

The Predator 8750 is slightly lighter than the Predator 9000.

Though it’s a few pounds lighter, the Predator 8750 generator is still difficult to move.

Technically, both Predator 9000 and 8750 are considered portable generators since they can indeed be moved. However, at 194 lbs. and 183 lbs., respectively, they’re not exactly easy to move about. At home you’ll likely want to place your generator in a shed or a covered area where it can be kept shielded from the sun and rain, and where its emissions won’t bother you and neighbors alike.

Thankfully, both of these generators can be fitted into a generator wheel kit so you can pull them out of storage easily when needed. They’re mounted on 8-inch flat-free tires with an adjustable steel handle covered with a slip-resistant padding. The open frame design allows them to be raised above ground level and makes them ideal for outdoor use.

The Predator 9000 and 8750 generators can be started with an electric starter or with a pull-start (recoil) mechanism as backup. The battery is not included in either product though, but it’ll make them much more convenient to start. Once running, both engines produce an average noise rating of 76 dBA, which is comparable to that of traditional vacuum cleaners.

Features

The Predator 9000 and 8750 generators have the same outlets and features.
