1 - How does the Electric Ox get such long run times?
The drive system of the Electric Ox is designed for both power and efficiency. By using an independent motor and gearbox for each drive wheel, power is used efficiently without the significant energy loss associated with a traditional transmission. The sophisticated electronics at the heart of the Electric Ox meter power exactly as required with no wastage. In fact, every time the Electric Ox slows down or brakes, the motors are turned into generators and deliver a charge back into the batteries, further extending the running time. The efficiency of the drive system allows the Electric Ox to use standard lead acid batteries and still deliver exceptionally long run-times on a charge.
2 - What are standard 'Run Times' for different applications?
Mowing Depending on the moisture content of the grass and the terrain the Electric OX - MP will operate for 3 - 6 hours before requiring a charge. If the grass is wet, new and thick (as in spring) and the ground is hilly then the load on the electric motors and the batteries will greatly reduce the run time.
Towing Operating times between charging in a towing application have been reported to be as high as 8/9 hours.
3 - What is the horsepower rating of the Electric OX?
Raw horsepower comparisons are not accurate because with a gas engine, a significant amount of energy is lost getting the power from the engine to the drive wheels. With the Electric OX, the power is already right where it is needed. The 48 Volt Electric OX will deliver performance similar to a 22-25hp gas tractor.
4 - What is an electronic differential and why do you use it?
With an electronic differential, there is no mechanical link between the drive wheels. The power is applied to each wheel separately by the speed controller. In a turn, the speed controller will apply less power to the inner wheel. This provides a light steering feel and a smaller turning radius than is possible with a traditional differential. In addition, an electronic differential simulates a differential lock while front wheels are driving straight. This means power is applied equally to both rear wheels. Practically, this means that the Electric Ox can pull more weight in more adverse conditions.
5 - I don't see "brakes" as a standard feature. How can that be?
The Electric Ox does not have a traditional braking system. To stop the tractor, just release the accelerator pedal. The electric motors are used to stop the vehicle. In fact, every time you stop the Electric Ox, the "brakes" recharge the battery. This "regenerative" braking action is very powerful and you will find that even with a load, the braking action is more than adequate. Once the vehicle is stopped, an automatic parking brake comes on to prevent the Electric Ox from rolling. Regenerative braking is "maintenance free" as all traditional mechanical brake components have been eliminated.
6 - The drawbar pull is rated at 700 lbs. but you say the Electric Ox can pull up to 7,000 lbs. How can that be?
The drawbar pull relates to the amount of force which can be exerted on a stationary object. How much this force will pull depends on the rolling resistance of the load. In ideal conditions, we have actually seen the Electric Ox pull up to 7000 lbs. In less than ideal conditions, it will pull less. The following factors all contribute to how much actual weight the Electric Ox can pull: weight of the load, number of carts, type of cart wheels, type of floor surface, degree of slope of the floor surface, traction conditions, straight pull or a pull with angles and curves, the length or duration of the pull and the speed of the pull.
7 - What is the difference between the Electric Ox and the Electric Ox - MP?
The only real difference is that the Electric Ox - MP has an electric lift system and is capable of accepting attachments. An Electric Ox towing vehicle cannot accept attachments but can be upgraded to do so at a later date.
8 - What are the operating costs savings between the Electric Ox and a 25 hp tractor when used in a towing operation?
Assumptions
5 hours of operations for 5 days a week for 50 weeks per year (1,200 hrs per year) Electricity cost - $0.09 per kilowatt hour Gasoline cost - $2.16 per US gallon.
Operating Cost
Electric OX $291
25 hp Tractor $2,595
Cost savings $2,543
R.O.I. 31 months
9 - What is the noise level of the Electric OX?
The noise level at the operator's ear is equal to that of a busy restaurant or office (72dB), while at 50 feet distance it is virtually silent.
10 - How long does it take to connect any of the attachments?
With the "Quick-Attach" patented mechanism any attachment can be connected or unconnected in less than two minutes.
11 - What are the maintenance requirements for the Electric Ox?Other than checking the tire pressures and tread wear and making sure the battery fluid levels are kept within limits there are no other maintenance requirements, unlike gas powered units that require oil, grease, tune-ups, belt and chain maintenance.
12 - Is the mower a mulching mower?
The mower deck is a side discharge mower, not a true mulching mower. However, at 3,600 rpm, the blades are rotating significantly faster than a traditional mower. As a result, the grass is cut several times before it is expelled from the chute. In addition, the sharp, thin blades ensure that the grass is cut very cleanly allowing it to quickly dry and naturally decompose.
13 - What safety features are available on the Electric OX?
* The Electric OX requires a key to have any features operational including the front lift system.
* A seat switch shuts off the tractor and attachments if the seat is empty (can't stand up to drive).
* If the pedal is depressed when the key is turn, the pedal must be returned to neutral before the tractor starts.
* The mower blades stop instantly (1/10th of a second) when the attachment is shut off.
* The mower power cable is too short to allow it to be plugged in while in the cleaning position.
* Both the key and the RELEASE button must be used to release an attachment.
* The very low centre of gravity means the Electric OX is exceptionally stable on hills.
* The electronic differential provides the benefits of a differential lock without the safety concerns.
* The automatic parking brake ensures that the parking is always on when stopped.
* The Electric OX will not operate while the automatic parking brake is disengaged.
