What are the main wearing parts of reversible plow?

Reversible plows are essential tillage machines designed to turn soil,bury crop residues and prepare seedbeds for planting.During field operations,the plow contacts abrasive soil,gravel and plant roots continuously.Constant friction and impact gradually wear down key components.Recognizing the main wearing parts of a reversible plow helps operators schedule routine inspection,replace damaged components in advance,reduce unexpected machine breakdowns and maintain consistent plowing quality throughout busy farming seasons.

The plow share,also known as plow point,is the most heavily worn component.It cuts into the soil and breaks the hard ground layer first.Made of wear-resistant steel,this tip bears the strongest friction and shock when hitting stones.As the share wears thin,penetration capacity drops,requiring more tractor power and leaving uneven furrows.Cracked or heavily worn plow shares must be replaced promptly to avoid damage to adjacent plow body parts.

Mouldboard is another core wearing part of reversible plows.It lifts and turns over the soil slice after the plow share cuts the ground.The curved surface of the mouldboard directly slides against soil.Long-term abrasion will smooth its curved profile.A worn mouldboard fails to invert soil properly,leaving stubble exposed on the field surface.Heavy clay or rocky fields accelerate mouldboard surface wear,and reinforced mouldboard plates are recommended for these tough working conditions.

Landside plate works on the side of the plow body to resist lateral soil pressure during plowing.It bears continuous side friction against the furrow wall.When the landside plate wears excessively,the plow body will shift sideways,leading to unstable furrow width and increased pulling resistance.Many reversible plows adopt replaceable landside wear plates instead of integrated structures for convenient maintenance and cost control.

Skate or runner wear strips are installed at the bottom of the plow body to support weight and reduce sliding friction.These strips slide along the furrow base and wear slowly over time.Once worn down,the plow working depth becomes hard to control,and extra load transfers to the plow frame and connecting hinge structure.

Hinge pins,bushings and lock fasteners are vulnerable wearing parts on the turnover mechanism.Reversible plows flip the plow body repeatedly through hydraulic power.The frequent rotation creates cyclic friction between pins and bushings.Worn pins and bushings produce excessive clearance,which causes shaking during plowing and inaccurate turnover action.Heat-treated pins and matching bushings can extend service life for the flipping system.High tensile bolts and cotter pins used to fix plow bodies also loosen and wear under continuous vibration,requiring regular checking and replacement.

Hydraulic connection parts also suffer from wear and fatigue.Seals in hydraulic cylinders degrade under repeated pressure changes.Damaged seals cause oil leakage and weaken the power needed to flip the plow.Worn hinge joints and connecting lugs may appear after long working hours under heavy load.

In general,plow shares,mouldboards and landside plates are primary consumable wearing parts directly contacting soil.Pins,bushings,fasteners and hydraulic seals belong to secondary wearing components for turnover and connection systems.Regular visual inspection and timely replacement of these worn parts keep the reversible plow operating smoothly,lower fuel consumption and extend the whole service life of the tillage equipment.
