QuestionHi, thanks for the fast response. I did what you said to, and got the following information:
Not running, the battery reads 12.42 volts
Running at full throttle, the battery reads 12.42volts, and climbs to just over 13volts
The numbers under the seat of the tractor read:
model # 13AM672G730 (529009-110)The number in parens. appears below the first number, i don't know what it means.
Serial # 1C217B40099
The numbers on the engine are:
Model# 287707
Type# 0644-A1
Code# 970120ZE
I assume you already know it is a B&S judging by what you asked for. I also had a couple other questions. First, there is a small ampere meter that fits in the dash that was disconected when i got the tractor, I was wondering how to go about re-connecting it. And secondly, I just replaced the blade deck belt, and now the blades are constantly engaged. I tried tightening the engagement rod, but the blades are never disengaged, even if the deck hits the pully on the engine, and loosening the rod just makes it worse. I was wondering if i put a belt on that is too short.
Thanks again for the fast response,
Doug Smith

Hi, i am working on finding the problem with a 1998 power pro lawn tractor by mtd. The battery is draining while the tractor is off, and the battery has been replaced twice. i don't know if it is not charging, or what is hapening. i know that there is a stator, or something under the fly wheel that is involved with the charging, and i have a multimeter, but am not sure about how to go about testing to see if the tractor is charging. i've heard about a charging diode shorting out. electrical problems are not my strong point, and the people at mtd are just looking to have me bring it in to the dealer.
Any advice would be greatly appreciated

Hello Doug:
No Worries. If you have a Multimeter you Good to Go on the Electrical Testing. With the Engine Running at Full Throttle, Check the Voltage at the Battery. It should Read 12.8VDC to 13.5 VDC. If Lower than 12.5VDC then you need to Check Further. Send me the Make, Model, Type and Code Numbers Off of the Engine and I can Locate a Breakdown of the Engine and Better Assist you. Some Engines have a Regulator and some Dont. The Model Numbers will tell me this and How I need to have You Proceed with the Testing of the Charging System. Thanks.

Answer Hello Doug:
Sorry for the Delay. We had Storms come through and I Lost Power. Im Back Now. From your Readings I can see that the Stator is Charging the Battery to 13.0VDC, which is Good. If the Battery is Losing its Charge, then Check the Starter Soleniod and the Ignition Switch. Check the Wires from the Battery to the Soleniod and to the Ignition Switch. There is a Draw on the Battery when the Ignition Switch is Turned Off. Do this Test. Use the Mower and when you aer Finished with it, Disconnect the Ground Wire from the Battery and Allow it to Sit this way for 2 Days. Check the Battery Voltage. Is it Still at 12.0VDC or Better after 2 Days. If Yes, then the Cause is in the Wiring Harness. I mean Either the Soleniod or the Ignition Switch or a Bad Wire that is Allowing the Battery to Drain During Non Use. You can View a Breakdown of the Engine at this Addy http://www.outdoordistributors.com/ and Click the B. Then Select Briggs and Stratton. Then Select Dont have Part Numbers. The Scroll Down to the File Number 28 and Click. Then Scroll to your Model Number 287700 and Click. This will Download a Illustrated Parts List/Breakdown for you to View Online. You can View a Breakdown of the Mower at this Addy http://www.buymtdonline.com/webapp/wcs/stores/servlet/BuyMTDOnline/index.jsp and Select Launch Illustrated Search Engine. Now Select the OEM (MTD Brand) and Enter the Model Numbers 13AM672G730 and Click Go. Now Double Click on the Model in the Search Results Area. A New Window will Open. From this Window you can View All the Mowers Components Except the Engine. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.
Good Luck

Hello Again Doug:
I forgot about the Belt. Check the Belt for Proper Length. The Brake Disc (Diagram # 28 in the Deck Assembly File) May need Adjusting. If the Blades were Stopping before you Changed the Belt, then the Belt would be the First Check and Then the Brake Disc. You can See the Part/Belt Numbers on these Site Also. Hope this Helps. Thanks.
Good Luck
