I converted a gas spreader to electric after an incident with Downeaster. It is a 8ft model that I cut down to run on my Toyota. The conversion saved me some weight and allowed me to better balance the spreader.
I have seen no real drawbacks. It is quiet, no maintenance and easier to control. One switch for power and then a simple speed control.
I talked to Downeaster yesterday.The largest electric unit they make is 2.5 yards add another 1/2 yard mounded so 3 total.
The Downeaster only comes with an on/off switch no variable speed.They also told me you must drive slower about 4 or 5mph.
I reminded him we could adjust the flow with the door and he agreed that we could probably drive a little faster.
And you can drive faster than 4-5 mph. Worst case I just go over an area 2x for full coverage. The apron chain speed is real slow 50-1 ratio, compared to like 25-1 for gas powered units. However i find that I use alot less material than in gas units,and get the same results.
I gotta agree with Dino as we use less material with an electric as the ratio is half that of a gas version.And yes you can drive faster than 4mph and still get good results.We just bought 3 more for some of the malls we are doing this season.The dependability of these units is stggering compared to the gas.
