The Core Of Three Precautions For Autumn Harvest Homework

1. Install a drum type cutting platform (specifically designed for corn/rice) to prevent straw blockage. Adjust the blade gap to 1.5 times the crop diameter (such as 3cm for corn stalks). Stop the machine every 2 hours and use a high-pressure air gun to blow away straw debris from the radiator gap in the opposite direction
2. Tire modification for preventing wetland sinking: replace with high patterned tires (tread depth>4cm) in paddy fields, install anti-skid iron chains in dry land for emergency rescue: cut off power when stuck → suspend agricultural tools to form a fulcrum → pad wooden boards under wheels+low-speed reverse
3. Install a spark collector on the exhaust pipe for fire hazards (self-made method: wrapped in three layers of wire mesh). Spray flame retardant (1:10 baking soda water solution) on the body every 4 hours
Part 2 Deep maintenance after autumn harvest, golden 48 hours
1. Clearing straw residue and removing the protective plate → using an air gun and brush to clean the accumulated grass in the engine compartment with a connecting strip and diesel to flush the hydraulic oil cooling pipeline
2. Key parts rust proof blades/bearings: grinding → applying waste engine oil → wrapping exposed metal with cling film: spraying water-based rust inhibitor (do not use butter to stick dust)
3. Oil system seasonal change - Diesel: replace with -10 grade (anti condensation wax) - Engine oil: SAE 10W-30 replace with summer oil - Gear oil: 85W-90 GL-5 low temperature resistant version

Part 3 Deadly Minefield of Autumn Harvest
1. The accident rate of forcibly pulling the harvester's roof through the power pole and touching the high-voltage line accounts for 43% of autumn harvest casualties! Folding the harvester when crossing obstacles → A dedicated person directs the overloaded transportation of grain
2. Tractor trailer loading height limit of 1.5 meters (high center of gravity can cause tipping), it is recommended to install anti roll brackets
3. Use harvester blades to clear the fields and crack tree roots/stones! Scan around the field before homework → mark obstacles. 4. When driving continuously for more than 8 hours, the engine must be stopped and cooled down. It is recommended to use a "4+1" system (4-hour operation+1-hour maintenance)V
