BLADE RITE 1750 MANUAL

(Cont.) It can be adjusted in and out by means of the feed handwhee [4].
The blade rest (support nger) [5] should be positioned as close to the grinding wheel as
possible, then feed the grinding head in so that one end of one blade is supported by the
rest with the grinding wheel hardly touching the blade (Very light contact).
Traverse the grinding carriage to the other end of the blade, rotating the reel with the other
hand to keep the blade supported on the rest. Contact between blade and grinding wheel
should be even along the blade length. Adjustment to achieve this can be made using the
handwheels on the left and right hand guide rail side arms.
(Generally raising a side arm, turn handwheel clockwise, will bring the blade closer to the
grinding wheel at that end, whilst lowering a side arm, turn handwheel counter clockwise
will have the opposite result).
Note: It may be necessary to re-adjust the position of the mower, to obtain the desired
relationship between grinding wheel and blade, in order to achieve the desired angle of
relief grind, but with experience this positioning becomes quick and easy.
3.4 Set the left-hand traverse stop collar on the guide rail so that the grinding wheel covers
the left-hand end of the reel blade. The reel blade stays on the blade rest whilst the index
nger [6] springs up above the blade ready for traverse towards the right.
3.5 Set the right hand traverse stop collar on the guide rail so that the grinding wheel and
blade rest (support nger just clear the end of the reel blade without coming into contact
with the mower’ side plate or frame). The reel rotates forwards and the next reel blade
pushes the index nger down aligning the blade so that it will run onto the blade rest when
traverse is to the left.
3.6 Adjust the “low” position of the index nger so that it leads the reel blades smoothly onto
the blade rest (support nger) The weight of the reel blade should not be at this index
nger during right to left traverse; Adjust the “high” position so that the index nger is just
clear (above) blades for r/h traverse AND is caught by the next blade when the reel rotates
at the index position (r/h traverse stop); If necessary the index nger can be adjusted in
and out of it’s mounting block (It is locked in place by a small grub screw).
