The idea is to maintain a squareedge and with lapping modes on many traction systemstoday, it makes the task easier than it takes more than two to five minutes to lap, one of twothings have occurred:1)The reel has dulled so badly that the reel and bedknife edges cannot be corrected bythis process (it will take too long to lap).

2 2)The relief has diminished enough on the reel that the lapping process is not relief on the reel blades provides anarea for the compound to adhere to,transferring more material between thetwo parts and making the process grit is forced to pass between thereel & bedknife, the relief provides lesssurface and less metal to remove,minimizing time for the on both the reel andbedknife contributes to amore effective doesn t require much compound todo the work, and two dips of the brushas seen in the picture to the right issufficient. After one pull of the brushas seen, apply from left to right, andthe second pull you apply right to left,and simply work the brush back andforth distributing the couple of lapping tips to ensure results meet the effort.

3 1) Redistribute the compound over the two to fiveminute process, as this prevents build-up of compound incertain areas that can possibly cause other ) Use quality lapping compounds that have a highgrade grit and a suspending gel that can easily wash can be effective earlyon, but pay attention to theamount of relief left as you getinto the season. A couple of touch-up spin grinds will bemore effective after a certainpoint and/or until you decide todo your preventive maintenanceand a full re-conditioning the relief on the blade wearsaway, lapping compound clings to theback of the reel blade, forcing lessmaterial between the two only is less grit forced betweenthe reel blade and bedknife, there smore metal to removeAs relief wears on the reelblade, more surface areaon the blade will reducethe life of the bedknifeBACKLAPPINGBACKLAPPINGBACKLAPPIN G ConclusionsBACKLAPPING Conclusions2)

4 manufacturers include lapping modes on several ofthe traction cutting systems sold in the field with intentof minimizing the effort to maintain a good cutting ) Remember, BACKLAPPING is only effective as part of apreventive maintenance program, as the reels andbedknives should be re-ground after a significantamount of the relief is ) As a grinder manufacturer, we don t care if you lap ornot, as our goal is to provide the education behind whatthe process should entail and what makes it are that lapping will not kill your turf, ruinbearings, or cause other issues when conductedproperly and done on a timely basis.
