13. GENERAL ADJUSTMENTS
SETTING FOR HEIGHT OF CUT
Alwaysstoptheenginebeforeadjustingtheheightofcut.Failuretodothismayresultinseriousinjury.Thelengthofgrassafter
cuttingdependsontheheightofthedeckinrelationtotheground.
To set:
● TurnHandknobontopdeck(ViewA)toraiseandlowerdeckheight.
● Usecalibrateddepthguage(ViewB)tomeasureheightofdeck.
●
Rememberheightofcutisa󰀨ectedbymoistureofturf,weightofmachineandthethatchdensity.Di󰀨erentmakesofmachine
cutatdi󰀨erentheights.Wesuggestyousetittoacoupleofmmaboveyourplannedheightandthencomedowninheightby
trial.
DECK BELT ADJUSTMENT
Toadjustthetensionofthecuttingbeltremovethedeckcover.Slackenthethreeboltstighteningthetensionassembly(circled),
thenadjusttensionviewthetensioningbelt(arrow).Ensure thebelttensioniscorrect,asanincorrecttensionwillresultin
compromisedbatterylifeandpotentiallycausedamagetothemachine.
