chirpy Posted July 25, 2012 Share Posted July 25, 2012 Hi,I have had a sit-on m ower for several years and although I bought a new battery this week the engine starts BUT the cutters when switched on start to rotate but immediately stall the engine.It is a oleo-mac hydrostatic auto. mower and I believe it has 3 safety devices,1.under the seat which has not worked for years and the mower still worked ok.2.behind the grass catcher and 3 near the footbrake.the dash has lots of lights indicating what is working etc. and these connect to an electronic card.A loud beeping noise as an audible warning is bleeping all the time but until last week I could still operate the machine.Any ideas to what could be causing the mower not to operate the cutting blades...before I have yet another expensive collection of mower by the shop.thanks1 Link to comment Share on other sites More sharing options...
Théière Posted July 25, 2012 Share Posted July 25, 2012 Has it got an electromagnetic clutch for engaging the blades (a switch) rather than a lever of some kind? Link to comment Share on other sites More sharing options...

Théière Posted July 26, 2012 Share Posted July 26, 2012 Then that would be my guess, sitting here at my PC miles away [:)]Those clutches are not cheap. Link to comment Share on other sites More sharing options...
Chancer Posted July 26, 2012 Share Posted July 26, 2012 Sounds more like the governor to me, does it stumble and stall as if there is not enough power to drive the blades?If so then it sounds like the governor is not working (its what pours on the coals when the engine is loaded), if it dies like the ignition is switched off then it sounds more like one of your electronic safety devices, perhaps one to stop you grass cutting if the blades are exposed, grass collector perhaps removed or not fully engaged or a problem with the microswitch/sensor.

chirpy Posted July 26, 2012 Author Share Posted July 26, 2012 Can the switch be by passed or connected direct to a wire with 2 push on connecters to check if this is the problem? Link to comment Share on other sites More sharing options...
woolybanana Posted July 26, 2012 Share Posted July 26, 2012 Would belt slip cause the other gubbins to trip? Link to comment Share on other sites More sharing options...
chirpy Posted July 26, 2012 Author Share Posted July 26, 2012 thanks,I have rechecked all instument lights and when switch on ignition but do not turn key I have a flashing battery symbol and the audible bleeping.Would an insuffiient charge in my new battery cause the engine to start but have insufficient strengh to operate blades for cutting?Battery about 12.2 volts and starts engine first time.thanks for yr input have a good time at the Olympics!!
