Defect, external manifestation, cause Troubleshootin
Agricultural implement is not maintained in transport position (lowering speed ex-
ceeds 20 mm per 10 min)
Tie-rod of governor control is not adjusted
correctly
Make adjustment, as given in section
“Adjustments”
Oil leakage along sealing rings of
cylinder piston or rod
Replace sealing rods of cylinder piston
Stop valve of the governor is not air-tight Adjust or replace the valve.
During draft control, change of ploughing depth exceeds agrotechnical norms, diesel
speed during overload drops
Speed correction valve is closed Turning hand wheel contraclockwise, increase
speed of automatic corrections.
Central link of the mounting unit is
set in the lower clevis hole.
Set central link in the upper clevis
hole, and if maximum ploughing depth
is not sufficient, set it in the middle
Power sensor is not correctly adjusted
Adjust power sensor, and then draft link
Draft link is not correctly adjusted Adjust draft link
Loosened tightness of split hubs on the in-
termediate roller
Tighten bolts of levers’ hubs 1.3 (Figure
7.10.1) on the intermediate roller
Broken holes on the fixed member and
frame of plough, connected with brace,
insufficient rigidity of plough frame
Repair the plough to provide rigidity of
frame and its coupling with fixed member
Control handle doesn’t return on its own from position “lift” to position “transport
neutral”
Jamming in coupling of control with draft
control unit
Remove jamming, scrape bright surfaces of
oint connections from corrosion traces, put
grease, if required
Bolt of fixing spring on the control
handle is too tight
djust spring tension of the fixing element on
the control handle
Tie-rod of regulator control is not correctly
adjusted
Adjust length of tie-rod
1,3 – bolts of levers’ hubs; 2 – RLL shaft
