Why won't my BigDog Series X engine start?
If your BigDog Lawn Mower engine won't start, starts with difficulty, or doesn't keep running, it might be due to several reasons. First, ensure you have enough fuel and that the fuel line isn't blocked; refill the tank or replace the line if necessary. Check if the fuel valve is open. Also, inspect the fuel filter for dirt and replace it if needed. Finally, make sure the choke is turned on.
Why is my BigDog Lawn Mower jerky when starting?
If your BigDog Lawn Mower is jerky when starting or only operates in one direction, the steering control linkage may need adjustment. Adjust the linkage to resolve this issue.
What to do if starting motor does not crank on BigDog Series X Lawn Mower?
If the starting motor on your BigDog Lawn Mower does not crank, ensure that the steering control levers are in the park brake position. If they are, the switch may need to be readjusted. Place the steering control levers in the park brake position or readjust the switch.
What to do if my BigDog Series X Lawn Mower has abnormal vibration?
If your BigDog Lawn Mower is vibrating abnormally, it could be due to several reasons. Start by checking the engine mounting bolts and tighten them if they are loose. Inspect the cutting blades for any bending or unbalance, and replace them if necessary. Also, ensure that the blade mounting bolt is tightened securely. Finally, inspect the spindle bearing for wear or looseness, and replace or tighten it as needed.
Why is the hydraulic system on my BigDog Series X operating hot?
If the hydraulic system in your BigDog Lawn Mower is operating hot and the oil in the reservoir smells rancid, there are a few potential causes. Begin by checking the hydraulic oil level and fill the reservoir if it's low. Also, the hydraulic oil cooler might be clogged, so clean the oil cooler core. If these steps don't resolve the issue, the hydraulic pump may be faulty, and you should contact your BigDog™ Mowers Dealer.
Why does my BigDog Series X circle or veer?
If your BigDog Lawn Mower is circling or veering in one direction, it could be due to the steering linkage needing adjustment; adjust the linkage. Alternatively, the tires may be improperly inflated; adjust the air pressure to 8 - 12 psi (55-83 KPa).
How to fix uneven cutting height on BigDog Lawn Mower?
If your BigDog Lawn Mower has an uneven cutting height, it could be because the blades are not sharp. In this case, you should sharpen the blades.

Finally, check if an anti-scalp wheel is not set correctly and adjust its height.
