The frame is used to fix all the woking parts of the plow,and is attached to the hitching mechanism of the tractor through the three-point hitch-tow points at the either end of the cross shaft and one point at the hitching hole of the headstock.犁体是犁的主要工作部件，起切土、碎土、并将其翻转和覆盖杂草的作用,20系列犁有前犁体和后犁体。

前、后犁体的区别，只是后犁体的犁侧板比前犁体稍宽、稍长并在尾部装一个犁后踵。

每台犁只有一个后犁体。

限深轮的作用是调整和控制犁的耕深，在存放犁时起支撑作用，在具有力和位调节的拖拉机上亦可不用限深轮。

The plow bottom is the principal component of the plow.It cuts,inverts and pulverizes furrow slices,and buries weeds.plow series of 20 has fore bottom and rear bottom, Thear bottom differs from the fore one in that the rear bottom has a widei and longer landside with a heel attached to the rear end of thelandside.Only one rear bottom of the plow.The depth wheel is fitted to control woking depth,and to carry the weight,when the plow is not in word.while in work with draft control or position control,the depth wheel may not be usd.3.犁的装配20系列犁的按装位置及尺寸见表二、图二。

Install place and length for plow serier of 20 are shown in fig 2 and table 2 respTable 2 Installlengtdh of plow表二、犁的按装尺寸4.犁在使用前的准备和调整：工作开始前必须检查犁的成套性和完善程度，检查各零件部件安装是否正确紧固，并在限深轮轴承内注入黄油，耕身调节丝杠处加适量机油。

装配好的犁应达到下列要求：(1)两个犁体的犁铧刃口的高度差，相差不的大于10毫米，各犁铧尖不得上翘。

(2)相邻两犁体铧尖的横向距离应为200±10毫米，前后距离为560±15毫米。

Before work it is essential to ensuret that all parts and accessories are in good order and check the tension of nuts and bolts generally.Greas the bearings of the depth wheel,and oll the depthadjusting screw.A properly assembled plow should meet the following requirements:(1)The differences in vertical clearance of the share cutting edges bottoms must be less than 10 mm and the share point of a borttom must not be higher than the wing .(2)The lateral distance of share points between to adjacent bottoms should be 200±10mm and the fore-and –aft clearance is 560±15mm.5.犁的田间调整和使用：犁的调整：犁的田间调整有以下几项(1)耕深调节：犁的耕深调节采用高度调节方法，既通过限深轮进行调节，将外套管上的紧固螺钉松开，再转动丝杠，顺时针转动时耕深增加，反之则减少，调至所需耕深后将紧固螺钉紧固。

(2)犁架左右水平调：当犁架左底右高时，可伸长拖拉机右吊杆，右底左高时则相反，直至犁架左右水平为止。

(3)犁架前后水平（前后犁体耕深）调整：前深后浅时，伸长拖拉机上拉杆，反之缩短上拉杆。

(4)耕宽调整：通过改变悬挂调节杆的长度，可以调节第一犁体的耕宽，伸长悬挂轴调节杆时，第一个犁体耕宽增加，缩短时则相反。

AdjustmentsThe major adjustments are as follw:(1)dpthThe working depth is controlled by the depth whell untighten the bolt on the outer square tube.Turn the adjusting screw clockwise to sink the plow and vice versa.when required depth is achieved,tighten the bolt.(2)Lateral levelingThe lateral leveling is done by adjusting the length of the right-hand suspension rod of the tractor.Lengthening this right-hand suspension rod lowers down the right side but til;ts up the left side of the plow frame and vice.(3)Fore-and-aft levelingPlow is leveled fore-and-aft by abjusting the length of the tractor top hitch link.shortening the link raises the rear of the plow and vice versa.(4)Adjusting the width of cut(s.fig.1)Front furrow width can be adjusted by changing the length of the adjusting rod of the cross shaft.Extension of the adjusting rod increases width of cut of the front furrow and vice versa.犁的使用：(1)工作时限位链应放松，以使犁有适量左右摆动，但摆动量不能过大，以防升犁后犁碰拖拉机轮胎，因此拖拉机下拉杆的限位链不宜过松。

(2)犁在工作中，应经常清除粘附在犁体上的泥土和杂草，否则将影响耕地质量并增加阻力。

(3)机组在地头转弯，后退及运输时，必须先将犁升起，以防将犁损坏，远程运输升犁后还应锁定。

(4)限深轮轴承处每班注黄油一哦次。

调节丝杠处应经常加适量机油。

Operation(1)While the plow is in normal operation,both chains connectad to the lower linkages must be loose so that the plow is free to swing sideways.but the check chains should not be too loose to allow the plow striking the tractor wheels,while in trasport position.(2)When the plow is in work,the plow bottoms must be free from mud and weeds,otherwise,poorplwing quality ands increase in draft would occur.(3)When backing or turning the tractor at the headlands,or during transport,it is necessary to raise up the plow form the ground to avoid being admagesd.For long distance transport the plow must be raised and locked up.(4)Grease the bearings of the depth wheel once a shift.Oil the depth-adjusting screw frequently.6.修理：REP AIRING犁铧磨钝后应及时进行修理，否则影响耕地质量和过份地消耗动力。
