Purchase was simple. I paid my money and Ace delivered it to my yard within a couple hours (they wanted to charge it fully and ensure that all the batteries took a full charge before delivery).
Driving
I lurched around the yard before supper and got a very slow mow in after supper.
I used the "comfort" setting on the controller and it turns out this was a mistake because in "comfort" it behaves
nothing like a standard zero turn.
During subsequent mows I tried out different settings and found out that I prefer "sport" setting with full speed available. I'm at about 16 hours now (24+ mows).
In sport each handle supposedly controls each drive wheel. This is not
actually true. It can be confirmed by pushing just one lever and watching both wheels turn. I guess they must have programmed some "features" in to try to make it smoother.
Driving the Thing
The seat comfort is excellent. There are a few spots more jarring than on the Kubota but with smaller tires with high pressure and less weight that is expected. It has cup holders. Open containers not really recommended because it doesn't ride like a Caddy. I'm not totally sure what I'd use it for. I tried a drink. I just ended up spilling a bunch and getting grass in my drink.
There is a nice pocket for my phone and the block I use to prop up the chute.
Biggest gripe is that I can feel the frame flex. Now I don't know what material they used, maybe it will handle the usage ... but I don't like flex. If there is an issue I can always weld it back together but this one leaves me curious about durability. I will not be pulling any punches with it though and it will be used flat out for a lot of it's mowing time.
Cut Time
I've gotten my mow time down to about a half hour. It is a huge time savings for me (this would have been the case with any zero turn).
Traction
If it had enough traction you could probably pop a wheelie? That's my biggest gripe with it though - the traction is awful. Even on dry grass it will sit and spin a wheel while trying to turn or lock a wheel in a larger radius turn. Backing into the shed if I don't slide the seat back so my weight is on the wheels it will spin when it hits the PVC. I'm severely tempted to try and find some AG tires because there is really no excuse for traction this bad.
Battery Life
Battery life is very dependent on the blades being on or off and has very little to do with distance or speed travelled. Various mows I've had 50%-70% remaining after mowing one acre. In ideal conditions I believe it could meet their 4 acre claim. My conditions are not ideal so that has met my expectation. I have mowed twice on the same charge a few times.
Slicing Grass
Cut performance is OK. There are 5 blade speeds. On the lowest if I'm working around our grove of shaggy hickories it works well, but bogs in heavy grass. Some reviews claim "no bogging like my diesel" - I guess these people have easier grass to mow? Even in "turbo" blade speed the blades will slow down and then you can hear them ramp up as they pull more watts out of the batteries. I find the power to be equivalent to my Kubota. If you drive to fast in grass that's too thick - you get missed blades. That's just how mowing works.
Here is a fresh mow at 6-8 mph on wet grass:
Two passes, to the left of the mower: low speed, lowest blade speed. Directly behind the mower highest speed (7-8mph) and 4th highest blade speed (I forgot to use "turbo"):
Either way the grass gets mowed.
The deck doesn't collect a ton of grass, if it does I generally just let it dry out and remove before the next mow. Maybe not best practice but it's the way it is.
Here are the six batteries removed from the egg sack like area of the mower. Power density has come a long way and I was surprised how little room they take up given that they replace a diesel can. Really not that much more space, especially when you consider they are mostly air on the inside to allow for cooling. Of course these charge in the mower - I can't remember why they were out at the time. I think the mower was left outside overnight while I made room in the shed for it.
Mower in the shed:
Charging
It charges fine on the power that I have in the shed. A 15A circuit is required. I have more detail on the charge behavior I'll describe another time. Total charge time is 2-4 hours depending on state of charge. My grass doesn't grow THAT fast so it works for me.
Other Stuff
As stated initially I use my mower for other stuff and within a week I had the Handozer hooked up to see if it could drag it around the driveway. Honestly, it pulled better than the Kubota. There was no cooling to worry about and running around the driveway for an hour took about 2% of the charge.
Lack of traction did make it difficult to turn but otherwise there were no issues.
I mentioned I use it for toting stuff around, here it is with the mini trailer on my small porch restoration project:
Bringing in the new material for the porch I did a bit of extra loading:
No issues hauling the weight. I have no doubt this could haul my cars around as long as you didn't need to exceed 8mph. I had a more comical photo of this thing hauling a 22' 2x10" but I can't seem to find it right now.
Summary
Bottom line. The Ego has done exactly as I expected it to. There have been no errors, no faults, no charging issues and I've never come remotely close to running out of juice, even when mowing, letting it set for 4 days, then mowing again. Big gripes are traction and Reverse.
Oooh I forgot to mention reverse. The brushless motors cog in reverse. I'm not sure if the motors are not sensored or if they are only sensored in one direction or what. The cogging is REAL bad. With a little bit of load or going up hill it's not as bad so it may be able to be programmed out. I should really do a firmware update and see if that solves the problem but I'm not a big one on hooking my things up to the internet for updates. It has a tendency to break more things than it fixes.
I'll give another update on the charging/electrical usage, and if anything goes right or wrong with it over time.
