darsky Posted May 10, 2014 Report Share Posted May 10, 2014 Tried to fire up the mower for the first time and was really hard to pull. I checked under and its the blade that looks a little rusty and really stiff. Would 3 in 1 do the trick? Link to comment Share on other sites More sharing options...
Weeds Posted May 10, 2014 Report Share Posted May 10, 2014 No rope or twine caught up in the blade? Worth double checking Link to comment Share on other sites More sharing options...
Andy Posted May 10, 2014 Report Share Posted May 10, 2014 Trying it isn't gonna hurt anything. Even a spray on lube like WD40, Fluid Film, Jig a Loo etc. would help loosen it up, if that's the problem. Link to comment Share on other sites More sharing options...
irishfield Posted May 10, 2014 Report Share Posted May 10, 2014 If the engine is tight... it's not the rusty blade causing it!!! Does the lawnmower have the safety brake on the handle.. you have to hold it down or the lawnmower stops? It's a brake, that locks the engine.. suspect that linkage / cable is loose and the brake is dragging. Link to comment Share on other sites More sharing options...
darsky Posted May 10, 2014 Author Report Share Posted May 10, 2014 when I tried to turn the blade by hand-very hard compared to last summer. Does that mean it needs to be lubed? Link to comment Share on other sites More sharing options...
davey buoy Posted May 10, 2014 Report Share Posted May 10, 2014 I hope you had the spark plug wire off?Check what irishfield is saying.You can hardly pull mine over when the pull bar is not pulled back. Link to comment Share on other sites More sharing options...
dhickey Posted May 10, 2014 Report Share Posted May 10, 2014 What kind of mower? Push or ride on? What make and engine? We need details in order to help. Link to comment Share on other sites More sharing options...
Big Cliff Posted May 11, 2014 Report Share Posted May 11, 2014 (edited) I suspect the blade brake is engaged, the cable could be broken/disconnected or even stretched. There are a few other things that might cause it but spraying the blade with WD 40 isn't going to solve any of them. DO NOT try to turn it over by putting your hand on the blade, if it ever did fire you will loose your hand!!!!! It sounds like you are not familiar with lawnmower engines, get someone who is to look at it for you before you get hurt!

darsky Posted May 11, 2014 Author Report Share Posted May 11, 2014 Cliff-wasn't trying to start it by turning the blade, Was only saying that the pull cord is very hard to pull AND the blade is quite tight as well. Link to comment Share on other sites More sharing options...
HTHM Posted May 11, 2014 Report Share Posted May 11, 2014 Turning the blade will have the same effect as pulling the start cord. ERGO the motor can start. Link to comment Share on other sites More sharing options...
Crazy Ivan Posted May 11, 2014 Report Share Posted May 11, 2014 Did you spray out the underside of the mower with the garden hose before you stored it for the winter? I did that once and a bit of rust got in the bearing making it hard to turn over. A blast of WD-40 cured the problem. Like others have said, pull the spark plug wire before looking underneath.

Big Cliff Posted May 11, 2014 Report Share Posted May 11, 2014 As HTHM said but to elaborate just a bit. When you turn the blade it turns the crank shaft which also turns the flywheel. As the magnets on the flywheel pass the coil it generates a spark and turning it by hand could cause it to fire (if the kill switch isn't working for whatever reason) at which point the blade is now going to be spinning much faster than you could remove your hand from the area (typically around 3000 RPM or 50 RPS X 2 ends of the blade). I just don't want to see you get hurt so at least get someone who knows what they are doing to help you, if you were closer I'd just get you to bring it here and I'd be happy to help out.

irishfield Posted May 11, 2014 Report Share Posted May 11, 2014 Same reason you NEVER touch an airplane propeller unless you plan to have it to start! As I noted and Cliff concurred... and you didn't answer.. does you lawnmower have a blade brake? Link to comment Share on other sites More sharing options...
darsky Posted May 11, 2014 Author Report Share Posted May 11, 2014 I am bowing my head in slight shame as I type this. Used to run an electric so no pull cord. Last year I bought the gas one soooooooooooo it was not quite fresh in my mind that I had to pull on the "safety bar" as I am pulling the cord. Once the brainfart was flushed I realized my error. Thanks for those who helped. Link to comment Share on other sites More sharing options...
