SUMMARY OF THE IMPRINTING PROCESS AND REFERENCES ROLLER:   The   imprinting   roller   should   be   operated   in   soils   that   are   dry   enough   to   not stick   to   the   teeth.   In   the   event   that   soil   does   stick   to   the   teeth,   they   can   be   cleaned   with a   crowbar.   Operated   at   the   recommended   4   mph   the   roller   will   cover   23   acres   per   8-hour day.   Stopping   for   filling   of   seed   hopper   and   greasing   of   bearings   will   reduce   the   daily coverage   to   about   20   acres.   Axle   bearings   should   be   greased   twice   daily   or   more   often where   the   soil   is   dry   and   sandy.   The   life   of   the   teeth   can   be   extended   by   reversing   the roller's   revolution   as   they   tend   to   wear   mostly   on   one   side.   This   requires   an   overhead hoist. BALLAST: The   boxes   on   both   sides   of   the   seedbox   are   filled   with   standard   paving   bricks (2"x4"x8")   with   peat   moss   added   as   a   shock   absorber.   Tightness   of   the   box   cover   bolts should   be   checked   daily.   The   roller   can   be   water   filled   by   using   the   special   socket wrench   that   was   provided.   Coat   the   threads   on   the   filler   plug   with   gun   grease   each   time it is reinstalled. TONGUE:   The    tow    tongue    is    bolted    to    the    stub    tongue    welded    to    the    tow    frame. Tightness   of   the   4   bolts   should   be   checked   daily.   The   tow   tongue   eye   is   hitched   to   the tractor by using the clevis (shackle) that was provided. TRACTOR:   The   tow   tractor   should   be   about   60   HP   with   tires   or   track   gauge   not   much wider   than   the   6-foot   roller,   otherwise   the   tracks   will   not   be   erased   by   the   imprinter.   A crawler   tractor   is   recommended   for   steep   slopes   up   to   3:1.   Use   on   steeper   slopes   is   not recommended. SEEDER:   The   seed   box   should   only   be   filled   half-full   with   an   average   weight   seed   mix. Only   with   a   very   light   seed   mix   can   it   be   filled   full.   Seed   should   be   removed   with   the   help of   a   vacuum   cleaner   after   each   project   is   completed.   The   seeder   slide   gate   should   be pulled   all   the   way   out,   wire   brushed,   and   treated   with   a   light   coat   of   spray   lubricant between   projects.   The   seed   gate   can   be   adjusted   from   zero   (fully   closed)   to   four   (fully open)   position   with   the   aid   of   2   wing   nuts.   With   a   15-lb.   seed   mix   the   seed   gate   should be   fully   open.   The   two   bearings   should   be   lightly   greased   once   daily.   One   grease   fitting is accessed by removing the agitator drive tire. This tire should be maintained at 15 psi. SEED:    The    seed    mix    should    include    early,    mid,    and    late    successive    species    for ecological   restoration   projects. An   equal   volume   of   red   flaky   wheat   bran   (a   byproduct   of the   milling   of   white   bread   flour)   is   mixed   into   the   seed   mix   to   prevent   the   separation   of light   and   dense   seeds   in   the   seed   hopper.   It   is   usually   better   to   mix   your   own   seed   mix than   to   order   it   premixed.   Also   one   should   order   seed   on   a   pure   live   seed   (PLS)   basis rather than bulk seed. Consider inoculating with mycorrhizal fungi. BEARINGS:   For   lubrication   see   "Roller"   and   "Seeder".   Periodically   check   bearing   bolts for   tightness.   Seeder   bearing   bolts   are   loosened   to   adjust   the   flexible   agitator   to,   in   turn, lightly   touch   the   bottom   of   the   seedbox. As   the   agitator   wears,   it   will   need   to   be   adjusted downward. One spare roller axle bearing was provided with the imprinter WHEELS:   Two   wheels   and   stub   axles   are   provided   for   field   transport   only   and   are   not   to be   used   on   highways.   For   highway   transport,   load   the   imprinter   on   a   trailer   as   described under   "Legs".   To   install   the   wheels,   use   a   HiLift   jack   and   the   square   brackets   on   the imprinter   with   the   imprinter   hitched   to   a   tractor.   Always   stand   clear   of   the   jack   and imprinter   to   avoid   injury.   Tires   should   be   maintained   at   60psi.   Small   leaks   in   tires   can   be fixed with a variety of commercial sealants. LEGS:   The   imprinter   is   provided   with   three   legs   tipped   with   steel   rollers   used   in   loading the   imprinter   onto   a   trailer.   Loading   involves   the   removing   of   the   tow   tongue   and   the winching   of   the   imprinter   along   and   up   steel   channels   (6"   x   10').   Channels   and   trailer   are not   provided,   but   winch   cable   shackles   are   attached   at   both   sides   of   the   imprinter   tow frame.   The   stub   axle   should   be   on   the   right   of   trailer   and   should   be   red-flagged   for highway transport.
