Electric Tractor Powered By Solar Or AC Outlet
 ✖  |
Whether it's charged by its solar panel or an AC outlet, the new Sun Horse electric tractor can do an hour of heavy tillage work or several hours of lighter work before it needs recharging, or it can be used for many hours to power AC tools. Developer Tom Lopez says the Sun Horse is ideal for market gardens or hobby farms such as his 5-acre operation.
"We replaced a 23 hp subcompact with the Sun Horse, and it does everything we need -- tilling, mowing, hauling and more," says Lopez. "Using the AC outlets on it we can trim all day with an electric chainsaw running off the tractor and still have enough power to drive home."
Lopez has been supplying solar-powered farming and gardening equipment since 1995. The Sun Horse Model 4812 takes his solar line to a new level. It has all the features of a standard compact or subcompact tractor, including pto and Category I 3-pt. hitch. A loader and other attachments are under development.
Lopez combined an 8 hp electric motor from D&D Motor Systems with a hydrostatic wheel drive from Parker Hannifin. The combination gives the Sun Horse a top speed of 6 mph with the torque of a 12 hp gas-powered tractor.
Power is provided by 8, 6-volt, deep cycle golf cart-style batteries with a plug-in-the-wall recharging system. The 200-watt solar panel with a 2,500-watt power inverter and two 110-volt AC power outlets are available as options.
"The solar panel will produce power whether the tractor is operating or not," says Lopez. "We'll do about 2 hrs. of work in the morning and then let it recharge all day while we do planting and other hand work. Then it's ready for another 2 hrs. of heavy work in the late afternoon."
In addition to the variable speed pto with 400 to 600 rpm's and the 3-pt., Lopez has designed the tractor to handle mid-frame attachments. Weeding, seeding, sweeping and mowing attachments are being field tested this year for introduction in 2012. A front-end loader is planned for 2013.
Standard features include on-board charger with battery status indicator, toolbox under the seat, LED lighting for front and rear, a roll bar and an adjustable seat.
Options for 2011 include a 300-watt sound system, a tool bin mounted behind the seat, mid frame tool hitch and a rear towing hitch.
The base tractor is priced at $13,500. It sells for $16,000 with all options. Lopez says state and federal rebates and tax credits should lower the base price to around $10,000.
