Added an Automower (430x) to a <1" KBG Reel Mowed Lawn

Since I wasn't able to locate info from others (on cool season lawns) low mowing with an Automower, I thought I would start this thread for others who may be considering trying doing so on their lawn. My front yard is Kentucky Bluegrass (new varieties in 2020), and the back yard is sod with ryegrass overseed.


Why I’m bought an Automower even though I love to reel mow:

  • My Obsession with lawn has become too much, and I’m loosing some of the enjoyment as I’m overly critical of any issues (weed, tire tracks, etc.). I’m hoping to take a slight step back and do family things, golf, etc. I want to enjoy reel mowing from time to time, but not all the time, it’s seeming to be more like a job at times.
  • I’m keeping up with PGR, fertilizer, and want to have more time to focus on that.
  • Overnight work with my job can cause multiple delays before mowing, and don’t want to worry about cutting off too much growth upon return, and I also want to be able to take a long vacation an not worry.
  • Less wear and tear on John Deere 220e reel mower.

What I’ve noticed with the Lawn in two weeks:

  • The stripes from the reel are very slow to fade. They are still noticeable when running the 430x, even a week after of automower only. This is good, as it preserves some of the reel mowed look, even as it’s fading away.
  • You can still stripe after the automower has been working for several days, but they seem slightly less prominent, than if only reel mowing and varying patterns.
  • The overall look of the yard is great so far. I am liking the solid green color vs. the contrast (light stripe, dark stripe). I would say overall it seems slightly darker green because of this. I still prefer the stripes, but the variety is nice to move between the two looks.
  • I think the reel mowed grass quality was better as all the blades were going in the same direction and looked more uniform. When you get right over the lawn, it’s not as consistent of a cut, but it’s not that noticeable from a distance.

Why I chose the Husqvarna 430x over others models

  • There seem to be a lot of automowers being introduced, but I wanted something that had been around and could be serviced. The reviews I’ve read seemed to indicate that Husqvarna is great, so long as you have an authorized installer in your area that can handle issues. Since I have one within 20 minutes from my home, and they gave me a great deal, I went for it.
  • I prefer a wired solution at this time. Like others that reel mow, I’m very meticulous with the lawn and will not be severing the wire due to lack of attention to detail. Also, I don’t mind fixing things that break, and I imaging this should be an easy repair if/when it happens. Also, I like that it cutting the grass multiple times from different angles and does not put a pattern in the yard. Also, the enhanced GPS, camera technology, etc. is still to new for me, and I don’t think they have all of the issues worked out yet.
  • I’m not interested in 9 inch stripes offered by the Husqvarna EPOS models and since I will still be reel mowing, there were no advantages to me purchasing the newer EPOS models that are 2x the price and would be fighting the 22 inch stipes from my John Deere 220e.
  • The narrow width of the cutting unit is best for my situation, as it will limit any scalping that could occur at the lower height and will create the most consistent cut on sloped areas in my yard.
  • 430x has the height range I’m looking for. I plan on cutting at or slightly above the length I reel mow at (.75-.95 inches). I have it on the second lowest setting which appears to be the same as .80 on my John Deere (measured with digital HOC tool).
  • The app has to work without issue. The Husqvarna has had a bit of time to get their app working and I’ve had no issues with it working on my android phone.
  • Must have GPS tracking if stolen from my yard (some other models do not have this).
  • The 430x model is rated for .8 Acres, and my lawn is about .2 Acres. Having an automower rated for an area larger than my yard was key for me as I don’t want it on the grass 24/7 trying to keep up. I’m intending on mowing around the dark times only (9PM-7AM)

Early observations of Husqvarna 430x (Only 2 weeks in)

  • The mower is very quiet. The only thing you can really hear is the grass being cut. When I started it, there were some longer areas that it had to cut, and that was quite loud. Now that I’m taking off very little, it’s very quite.
  • It runs about 2 hours, rests for 1 hour and resumes after charging. I run it from 9:30PM to 7:00AM (8.5 hours) but may back off a bit as I experiment more. The 450x will run quite a bit longer and rest a little longer, all while driving quicker, which allows you to cover a bigger yard. The 430x seems to be a good size for my situation.
  • The first 4-5 days running 24x7 were not targeted as it learned the yard. The unit went all over the yard and was not really covering it well. By day 5 it seemed to be mowing specific regions with a purpose (although still pretty random), so I’ve backed it down significantly.
  • I’ve not noticed areas that are being missed. It seems to be cutting everything evenly without any missed patches of grass in the yard. That was a major concern as I was not willing to use, if it resulted in a patchy lawn.
  • It’s too early to report on the blades, as this could start impact cut quality as the mower ages (I’ll update on this). The leaf blade cut quality appears to be great so far. I do plan on changing them every 2-3 weeks. This is a descent annual cost, and should be considered. I think many people do not change them nearly enough, if you are going for clean cut blades. This is critical if mowing at or below 1 inch.
  • I have lot’s of mulch and squirrels, chipmunks, etc. that move it a bit. I had them set the mower cable back a bit from that as I will edge, etc.. I was not willing to have the mower go right up to the mulch beds to be dulled interfering with cut quality.

I’ll continue to update for those who may be considering an automower for short mowed cool season lawns, as I’m sure there will be additional findings as the weather changes and during different times of the year.

Let me know if you have any questions!

Here are some pics today:

Cut on setting #2 (claims 1 inch, but I think it's closer to .80)

You can still see some of the lines from cable machine, but they are fading each day.
Image


Scalped areas is where I modified my line a bit.

Image



Back Yard (KBG Sod and Rye Grass Overseed)
Image


The stripes from 7 days ago are present, but slowly fading.
Image


The Square/Rectangle Patches throughout the yard are where I used a manual sod cutter to dig out Poa Triv Patches earlier in the spring. It was not a fun job. I Pulled sod from one side of my yard (see large rectangle at top of pic) to fill holes and then installed new sod back down in the donor area.

Late July Update:

I've only reel mowed 3 times since getting the Automower and it's been great!

The last time I reel mowed was for the 4th of July, so it's been about 3.5 weeks when I took these new pictures. It's been a while since I've fertlized, so it could use some for green up. When I do reel mow now, I double stripe to make a diamond, or go over the same line multiple times to make them more prominent. I thought I would want to do a lot more reel mowing, but have found that I use my time for other things, like weeding and golf :).

I've been good about changing blades every 14-21 days, but don't know that they need it. The blades on the mower are about 18 days old. I've been running the automower from 9:30PM to 7:30AM every day, and the lawn is a consistent length throughout with no missed patches.

I've kept it on setting 2 (the second lowest setting) and I believe it cuts close to .9 on my reel mower.

I strongly recommend to anyone one with cool season grass wanting to go low without the committment, or having a tool to augment your reel mowing for vacations, or when you just need a break.

The installer didn't seem to have any issues despite me having several trees and shallow roots. The machine they used cleanly sliced the ground and was not very noticeable. It's a basic slice and wire drop vs. a sprinkler install, which requires a lot of disruption to the soil. I didn't have to do any leveling or notice any dirt outside of the narrow hole that was made and it self healed within 2-3 weeks and became unnoticeable.

The wires do carry a very low voltage current, i guess similar to that of a dog fence, that the mower uses as a stop, so that it can cut clean along the edges of the yard.
It looks like depending on the severity of these wires being waterlogged it could impact the ability of the communication to travel from below ground to the mower in those locations. You would likely need to set that wire a little higher and not burry so deep in those locations. Also, I would suggest not mowing saturated areas. I have been careful not to run mine when there is severe rain or standing water (which really only happens for me in the spring).

If you have water logged sections during certain times of the year, there are temporary options you could use to keep the mower off of that area.

I was surprised, I paid less going through my local dealer (including free install), and have a better options for long term warranty support and repairs, vs. purchasing through amazon, etc.

Hey Longtee,
What a great thread! I’m currently deciding on whether or not to bring my kbg here in Colorado to 1”. Any suggestions on how to do this? Should I let my yard really fill in at 2.5” HOC before going low? We get really hot here in the summer and I’m concerned about extra stress with the lower height. How’s your experience been? Thanks again.

Hi @Aubie1983, I think you should be able to do it in Colorado but I'm not sure what climate zone you are in. I'm in Zone 5b in the central Michigan area. If you dropped it from 2.5" to 1", the biggest thing to consider is that are are going to need to mow it more often, since you really don't want to cut off more than 1" at a time, even less if you can. I would not worry about having it fill in first, but you should probably focus on dropping it down over a couple of weeks. Just mow it every couple of days and work it down slowly. Where this goes bad is if you attempt to do this when the grass is not growing (either too early in the spring when it's still a little dormant) if you do it right before it slows down in the summer. If it does scalp a little as you lower you are probably taking too much off at once.

You really need to have sharp blades too, when you start getting around 1 inch (and should have either a reel mower, or an automower with sharp razor blades).

The nice thing with the automower, is that you can easily move it up a bit if you want to in the Summer, and then bring it back down when things cool down a bit. Even with this option, I kept it at 1" (setting 2 on the low mow version of the automower) for the entire Summer.

As it relates to water, I really don't water any more than before I mowed low. For years I always mowed at the highest 4" setting. I now wait until I see the grass starting to stress a little and then hit it with a longer cycle. I do think you have to pay closer attention with this approach, but it saves a lot of $. I also do a good amount of spot watering with the hose in my front yard, that has issues with the tree roots competing with the grass for water.

You really need to have an irrigation system to pull it off at the shorter height. You will find that cutting it frequently and lower is going to make it really thick (as long as you have a good amount of sunlight) and I do think that this help to keep it from drying out. If you mow low with KBG in a shady area, it will struggle to get thick and never thrive.

The biggest issues I have in my climate area that seems to only effect low mowed yards is lawn fungus. You will likely experience this, and certain times of the year and will need to prevent or treat. Not a big deal, but it is something that you bring out by cutting it lower and thickening it up a lot.

I would say just give it a try. If it doesn't do well, or becomes to much, you can just let it grow out, no harm.

Let me know if you have any other Q's!

Could you program it to possibly make some pretty cool designs for the major holidays?

Props to you for realizing the turf was starting to interfere with day to day things. Sometimes we have to remind ourselves "it's just grass."
I think that's coming in the future, with the newer models, but my 430x is an older version that is all random and uses the border wire to atay in the yard. Looking forward to getting it going this season as I upgraded the cutting discount to their newest 5 blade model vs the 3 blade that was on it last season!
