correctly. The upper link is for adjusting the fore-and-aft leveling of plow stock and the
penetrability of the plowshare. Right & left lifting rods are for adjusting the plow
stock’s crosswise leveling. The land-wheel is for plow-depth control if there is one
provided. Adjust the land-wheel first at the beginning of plowing, when one plow share
has reached the required plowing depth, adjust the upper link to make the plow parallel
to the ground surface, then adjust the length
of left or right lifting rod to make depth the same of each plow. For the second bout
plowing, since right wheels of the tractor get into the furrow, the plowing depth of the
right side plow share will get increased all of a sudden, so right lifting rod and the
length of the upper link need to be readjusted again in order to get same plowing depth
of every share.
Adjustment of the length of the check chain: The check chain limits the deviation
between lift linkage and implements. During plowing some deviation (about 5 cm) is
needed to assure the plow’s automatic center resetting. But if the deviation is too much,
plow will hit rear wheels of the tractor and cause damage. Since no deviation is needed
for rototilling, just lock tightly with nuts after adjusting. Connect the two lower links
with the check spring after demounting implement so as to avoid their touching the
tyres.
Points for attention:
a.
Never
adjust the upper link and left or right lift link to the minimum length at the
same time, otherwise the implement will possibly knock at the cabin or the driver
when it is rising to the highest position.
b. To avoid opening the safety valve,
Never
move further the control handle
backward after the implement reaches the highest position and gets neutralized
automatically.
c. Driving away and turning operations of the tractor are prohibited while the
attached implement is not yet lifted off the ground.
d. Make sure the implements fit the tractor well and there is no interference of
implements’ lifting or lowering.
e. Attention must be paid to avoid implements’ running into earth bank or shaking
violently, the low speed gear must be used when crossing the fields so as to avoid
any damage of the tractor or implements.
4.3.2 Operation of PTO shaft
a.
The PTO shaft speed has the combination of 540 and 1000 rpm. It can be realized by
shifting the speed-changing lever of the PTO shaft.
b.
Input rotational speed of the PTO driven implements must be the same of the PTO
shaft’s, since the improper matching will cause serious premature failure of the tractor
and implements, and also effect the farming job quality.
c.
Shift the control handle forward to disengage the PTO shaft, dismount drawbar
coupling and the PTO shaft guard, then connect PTO shaft with a specific farm
implement. The PTO shaft speed of tractor and the required input speed of farm
implement should be identical.
d.
Fix firmly the tractor and implement if some stationary job is to be done.
