2. When the agricultural vehicle is in motion, it is often checked on the connection parts such as the steering arm fixing nut and the steering ball pin of the steering system. If looseness is found, it shall be fastened in time; if the abrasion is too great, it should be replace.
Coated Fiberglass Geogrid: Ultimate tensile Strengths from 30kN/m to 400kN/m,Fiberglass geogrid range: Biaxial, flexible high modulus Fiberglass geogrid impregnated with bitumen using the knitting process.
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.

1, regular maintenance, if you find the steering wheel and worm gap is too large, you should replace the new roller. 
3, agricultural vehicles in the vehicle before and during the trip, often check the tire pressure, so that the four tires are basically balanced air pressure to prevent tire inflation due to uneven tire pressure. Once a puncture occurs at the rear, the driver should not panic. Never make an emergency brake. Reduce the throttle and reduce the speed. Lightly press the brake pedal to stop the vehicle slowly.
Agricultural vehicle steering failure prevention measures
Agricultural machinery is now widely used, and failures cannot be avoided. It is very dangerous for agricultural vehicles to turn to malfunction when they are in motion. Lighter vehicles can't travel normally. Serious ones can cause major accidents such as crashes, overturns, and injuries. There are three ways to prevent agricultural vehicle from turning to failure:
