How to fix ?
If your John Deere tractor riding mower decreases in power halfway through the mowing job, there could be a couple of reasons as to why this is occurring. The first thing you should consider is the grass that you are cutting, as you may be trying to cut too much. The most common cause for the engine not turning over is simply the battery. Either the battery itself is dead, the terminals are corroded so the current can’t travel through them, or the battery cables themselves are damaged.
