Some Brigg's and Stratten motors have an oil level switch. When you go on a slope if it is really steep the oil level switch will think there is no oil in the motor so it will shut off. If you have that steep of lawn your best bet is to get a lawnboy lawnmower because they don't have that problem - they use mixed fuel.
it could be caused by a few different things. the pneumatic governor or a fuel issue. an easy test is to hold the throttle on the carb closed to an idle. if it continues to surge then it is a carb issue, if it stops it is a governor issue
When the grass stops growing--some time in early-mid December. Then start mowing when it starts to green up--some time in March.
The steep slope stops and slows down the wind,then the wind goes back to normal speed.
Slope
Continental Slope
After sitting all winter, it could have water in the gas. Add some dry gas and fill with fresh fuel. If it's an older engine, the coil might quit working when it gets hot. Next time it stops running check to see if you still have spark at the plug.
Friction will cause a body to slow down or stop moving. A weight on a down slope will descend faster if the slope in wet, as the water will act as a lubricant.
check to be sure the blades have free movement. usually if you have this problem it is caused from something stopping the blades from rotating therefore it stops the engine
Bad armature or coil. They are heat-sensitive.
In mathematics, particularly in calculus, a stationary point is an input to a function where the derivative is zero (equivalently, the slope is zero): where the function "stops" increasing or decreasing (hence the name).
Assuming this is a vertical shaft unit look at the base of the engine. You'll see a small plug with either a thumb handle or 2 pips to unscrew the plug. After you remove the plug add good quality oil to the top of the cast slot in the bore of the plug opening. To drain look under the unit for a square pipe plug. Drain oil warm and replace plug after all dripping stops, refill with fresh oil.
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
