There are roughly three reasons why tractors are powerless: the engine is weak, the drive belt slips, and the clutch slips. How to diagnose? Start the engine first and disconnect the clutch. Put on the brake and step on the brake pedal to make the vehicle in braking state. Then increase the throttle, slowly engage the clutch, and observe the tractor's operation.
1. If the diesel engine is emitting black smoke and does not increase the speed, or even extinguishes, the engine is weak.
2. If the diesel engine is operating normally at this time, the tractor will have a tendency to go forward, but there is a burning odor of rubber, accompanied by a "click" sound, indicating that the drive belt slips.
3. If both the diesel engine and the drive belt are working properly at this time, the tractor is still in motion and there is abnormal sound, indicating that the clutch slips.
Standardized Herbal Extract
A standardized herbal extract is an herb extract that has one or more components present in a specific, guaranteed amount, usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is getting a product in which the chemistry is consistent from batch to batch. This practice has developed out of the drug model of herbal medicine, in which modern scientists have attempted to identify the components of a plant that have definite pharmacological activity in the body. Unfortunately, while scientists can isolate many constituents from an herb and discover how particular chemicals may act in the body, they inadvertently remove or overlook components that may contribute to the activity of the whole herb. Consequently, standardization may concentrate one constituent at the expense of other potentially important ones, while changing the natural balance of the herb`s components.
