14.2 ADJUSTINGTHECUTTINGDECK
Good planarity of the cutting deck is essential for an evenly mowed
lawn. Place the lawnmower on a smooth, level surface, make sure the
distributorleverisoatingandlowerthecuttingheighttotheminimum.
Then:
1. Check the correct tyre pressure (1.5 bar);
2. Check the distance of the edge of the cutting deck from the ground
at the points indicated (g. 27). InA the measurement must be
15/20 mm, in B it must be greater than A by about 5/10 mm;
3. If necessary intervene:
- Onthefrontwheelslots(g.28)toadjustthedifferenceinheight
between the left and right-hand sides;
- Ontheadjusterattherearofthecuttingdeck(g.29)toadjust
