Small Engines (Lawn Mowers, etc.): Transmission slippage or drive power part II, transmission slippage, assistence


Question
Thanks.  I'll adjust the linkage as you suggest and check for plugs and refill levels.

Unfortunately I ran the car engine each time jumped the tractor. How can I check for damage on the stator?  Is this the generator?  Once started the battery was charged enough to start a warmed engine?  Is this a good sign?

Hello John,

The history from my previous question and your answer are below... this is a follow up question.....

I replaced the drive belt.  Thanks for your assistence. This went well.  However, I am not certain the I completly solved the problem.  Up hill is still a bit weak but much, much better than before. Reverse is good / forward a bit weak.... Can you suggest next steps to get improve forward power..  Is there a linkage adjust routine you could suggest to prove I have solve the problem but need to just find correct linkage adjustment? Could Hydro xmission be the problem?  Any othe suggestions?

Also has been hard to start this season... I replaced air, fuel, and spark plug but still hard start on initial start up... after warmed start is good..  I jumped several times this past summer with car battery ... did I do damage or will I have to install a car battery (*joke).

Thanks for your assistence,

John

Hello John,

I have 7 yr old Ariens model 936016 Sierra 1340H 13HP lawn tractor.  The transmission is recently too weak to make it up slope in yard.  I adjusted the linkage. This helped for about 10 minutes.  Reverse is also weak but weaker after linkage adjustment.  Can you suggest repair?  Possibly the belt? Can you point me to instructions on belt replacement?  If belt, what else should be replace other than belt?

Thanks,

John

Hello John:

 This is a Hydro Transaxle and the Belt is the Most Likely Cause for this Problem. The Mower Deck will have to be Removed from Under the Mower. You May have to Remove the PTO from the Crankshaft. Sometimes you can Remove the Belt Guard and have Access to the Drive Belt Without Removing the PTO. You can View a Breakdown/IPL of the Mower at this Addy http://ariens.com/ and Select Enter Ariens Web Site. Then Select Parts Radar from the Left Column. Then Select "Click Here to Enter Parts Radar." Then Select the OEM(Ariens Consumer) and Enter the Model Numbers 936016 and Click Search. Then Double Click on the Model in the Search Results Area. Then Select Engine and Belt Drive. You May have to Reset the Linkage to it Original Settings to Get the Motion Drive Working Properly. The Belt is the 1st Thing to Check when having Slippage of the Motion Drive on Ride On Mowers. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John

 Hello John:

 If you Moved the Linkage, then you need to Return the Linkage to the Proper Position. I Rarely have to Adjust the Linkage so I haven't a Routine. I Just Set and Try, then Reset and Try. Does this Hydro have Rubber Plugs on the Top of the Housing on Either Side of the Cooling Fan? If Yes, Then Remove Both Plugs and Add 1/2qt SAE30 Engine Oil. and Replace the Plugs. The Reason for Removing Both Plugs is 1 Plug is to Vent Air when Adding the Oil. If the Starter id Good and Not Dragging, then The Hard to Start Sounds like the Valve Lash needs to be Adjusted. You Probably Didn't do any Damage. I Jump Start Mowers all the Time with Car Batteries. Don't Jump a Mower with the Engine Running on the Automobile. The Alternator will Back Feed the Stator and Damage it. Then the Mower Won't Charge the Mower Battery. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks. Be Safe.

Answer
 Hello John:

 Use a Volt Meter and with the Engine Running at Full Throttle, Check the Battery Voltage. The Voltage should Read 12.5VDC to 14.5VDC. If the Voltage is Less than 12.2VDC(usually shows when Battery is Fully Charged), then the Stator or the Regulator(if this model has one)is Bad and needs to be Replaced. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks. Be Safe.

 Good Luck
