|Location||Oxford, Nova Scotia Canada map|
|Vehicle|| Ariens Riding Mower |
An old Ariens RM27.
|Motor||Etek Permanent Magnet DC|
|Drivetrain||9 hp B&S that wouldn't start. V belts to the gearbox and mower deck.|
None needed. Ground speed is controlled by the gearbox.
|Batteries||3, 12.00 Volt, Lead-Acid, Gel|
The batteries were cycled out of a Freightliner sleeper cab and sold for @$6 by my local Recycling Depot. They have been cycled about 40 times in the past year.
|System Voltage||36 Volts|
|Charger||Lester Golf cart Lestermatic.|
I had to take the old golf cart to get the charger , but it works fine. I made a solar array this spring and have just moved with a solar charge; a savings of about 30 cents. Two days of sun charges the battery pack.
|Heater||Sometimes it's hot and sometimes it's cold.|
|DC/DC Converter|| |
Coming. Using a 12 volt tap upsets battery balance and range.
|Instrumentation||Digital combination amp volt meter. This is a Chinese panel meter from Ebay at a good price.|
|Top Speed||It goes too fast for my rough lawn.|
|Range||I can mow for 1 1/4 to 1 1/2 hours and do 1/2 my lawn on a charge. This is about 1/2 acre per charge.|
|Seating Capacity||1 adult|
|Conversion Time||More time spent web surfing than actually working. It only took a couple of days after my MTD broke.|
|Conversion Cost||Etek $400|
Wiring and fuse $75
Old mower $100.
|This mower is narrow enough to pull a load of wood into my basement. Moving 7 1/2 cord with a hand cart was not good for my back.|
The deck can be lifted higher than one on an MTD. I no longer hit rocks, stumps etc.
The motor is stronger than the transmission which slips when pulling a lawn roller uphill.
I developed a wiring system with safety switches using 2 seat switches ( 1 NO , 1 NC ) and a single relay. After breaking both switches twice, I gave up on a seat switch: my lawn is too rough and too steep. Now I just try not to fall off.
The Etek goes 70 rpm per volt. 2550 rpm seems good with a 30 inch blade. I don't really want a higher tip speed.
Everyone here I contacted for advice was great. Thanks for the help.
