The ATV pull behind lawn mower is a very unique mower. It is connected to the ATV and there may be a control box on the ATV or on the mower itself.
The key is normally on the control box and you turn it and either nothing happens or the starter may try to turn the engine over and it won’t start. If you turn the key and nothing happens, check the battery and the fuse to ensure that the fuse is not blown and the battery has a full charge.
If the engine turns over but won’t start, check your fuel supply first. If you have fresh fuel, make sure the spark plug wire is attached to the spark plug. You can also check for spark using a spark tester. If you have spark, then you may not be getting any fuel to the engine.
Crank the engine over several times and then remove the spark plug to see if it is wet. If it is wet, then you may have another issue such as leaky valves or bad compression. If the spark plug is dry, then the carburetor may not be delivering fuel to the engine or your valves may not be operating.
