RANSOMES SPORT 200 & MAGNA 250 CUTTING UNITS
SAFETY, OPERATORS, MAINTENANCE & PARTS MANUAL
Fig.7
to attain the correct cutting relationship of cylinder
and bottom blade. NEVER PLACE CYLINDER
HARD ‘ON CUT’, and by anticlockwise rotation of
handwheel try to attain the correct cutting
relationship.
3. If cylinder is placed too hard ‘on cut’ it must be
adjusted to clear the bottom blade by anticlockwise
rotation of handwheel then re-adjusted back down to
the bottom blade.
4. THIS IS A SELF LOCKING MECHANISM THERE
BEING NO NECESSITY TO UNLOCK OR LOCK THE
MECHANISM.
TO ADJUST SPANNER TYPE:
1.
Slacken the cutting cylinder clamp nuts and
bolts (48 Fig.7) on both sides of the unit and
adjust the nuts (58 Fig.7) to bring the cylinder
slightly off cut so that it will revolve freely.
2. Adjust the cylinder down to the bottom blade on
one end of the unit until the blade of the cylinder
lightly contacts the bottom blade. Back off the
adjustment slightly until the blades are just clear
of each other.
3. Repeat the adjustment on the opposite end of
the unit until the cylinder contacts the bottom
blade.
4. Finally, the first end of the cylinder should be
adjusted down again so that it just contacts the
bottom blade.
5. Re-tighten the cylinder bearing housing clamp
bolts and nuts (48 Fig.7) securely.
NOTE: When using the above method it should
be possible to rotate the cylinder freely during all
stages of adjustment.
CUTTING CYLINDER BEARINGS
The cutting cylinder bearings are self adjusting taper
roller bearings and require no adjustements.
FRONT AND REAR ROLL BEARINGS
The roll bearings are self adjusting taper roller bearings
and require no adjustement
GRASS DEFLECTOR
The grass deflector can be positioned by hand as it is
‘friction clamped’ by nuts (tightening the nuts will
increase the clamping effect).
VERTICUT REEL ADJUSTMENT.
The position of the reel must not be altered after being
set. Any changes required in height must only be made
by moving the front and rear rolls. Normal setting of the
blades is that the tips should be 3mm (1/8 in) above the
ground. The blade tips MUST NOT penertrate the top
surfaceof the soil.
To Adjust :
(a)
Release bolt and nut at front end.
(b) Turn adjusters above rear roll clockwise to
reduce height of cut and anticlockwise to
increase height of cut.
(c) Re-tighten nut at front of skid.
