A guy in one of the robotic mower Facebook groups posted a photo last spring of his 115H sitting sideways in the grass, front wheel completely gone, just the axle hanging there. Turns out a sprinkler head had caught the wheel wrong for months and slowly chewed through the plastic housing until it finally snapped. He was ready to write the whole mower off and buy a new one for two grand. Someone in the comments told him the front wheel assembly runs about $33 and takes ten minutes to swap. He fixed it that weekend.
That thread stuck with me because it’s such a common story with these machines. People assume a broken part means a dead mower, when really the 115H is built from a small list of swappable pieces that Husqvarna sells individually. You just need to know what’s actually available and what part numbers to look for.
Quick answer: The main replacement parts for the Automower 115H are the front and rear wheel assemblies, the battery, the cutting disc and blade set, the charging tower and baseplate, boundary wire connectors and couplers, the blade motor, and the low voltage power cable. Most of these are listed under Husqvarna’s official spare parts catalog with specific OEM part numbers, and several also show up from third party robotic mower parts shops at lower prices.
Wheels
The wheel assembly is probably the part people replace most, since it’s the piece doing all the physical work against roots, sprinkler heads, and rough patches in the lawn. Husqvarna’s own spare parts listing shows the wheel assembly under part number 591 20 36 dash 02, and it’s listed as a two piece kit in the official catalog.
Third party suppliers sell the front wheel assembly on its own for around $33, and there’s also a combined wheels motor kit covering both the 115H and 315X that runs closer to $130 to $150 depending on where you buy it. If you’re only dealing with one damaged wheel, buying the single assembly instead of the full kit saves you money.
Rear wheel parts get sold separately too. You’ll find a rear wheel cover (part 582 28 02 dash 01) and a rear wheel washer sold individually, which matters if your issue is a cracked cover rather than the whole wheel failing.
Battery
The 115H runs on an 18 volt, 2.0 amp hour battery rated at 36 watt hours, listed under OEM number 593 24 72 dash 01. This same battery fits the 305, 310, and 315 models too, so if you’re shopping around, searching just “115H battery” sometimes turns up fewer results than searching the shared part number across that whole battery family.
Pricing runs close to $190 to $200 for a genuine replacement, and third party suppliers note this battery variant is meant for mowers built from a certain serial number range onward (roughly serial numbers starting with 2006 or later), so check your mower’s serial plate before ordering if your unit is on the older side.
Cutting disc, blade motor, and blade set
This is the whole cutting system, and Husqvarna’s spare parts document breaks it down piece by piece. The full “cutting system, high cut” kit is listed under 595 15 87 dash 01. Under that sits the cutting disc guard (593 73 53 dash 01), the cutting disc itself (593 58 93 dash 01), the screw that holds the disc (590 50 87 dash 01, needed in a quantity of three), and the blade set, which comes as a nine piece blister pack of Long Life Safety Blades under part 577 86 46 dash 03.
Blade motors themselves aren’t something people swap often, since they tend to outlast the blades by a wide margin, but they do show up in the parts catalog under the blade motor and cutting equipment section if yours ever fails.
One thing worth remembering here, always replace the screw along with the blade. Mismatched wear between an old screw and a fresh blade throws the balance off on the cutting disc, and that shows up as an uneven cut pretty fast.
Charging station parts
The charging tower itself is listed under 593 24 64 dash 02, and it comes as a full standalone unit rather than something you’d rebuild piece by piece internally, since Husqvarna notes elsewhere that the charging tower isn’t a serviceable unit on the inside. If the circuit board inside it fails, the whole tower needs replacing.
The charging plate (593 73 57 dash 01) and the Husqvarna cap piece (591 43 42 dash 01) are both sold separately if the damage is cosmetic or limited to just those components rather than the whole tower.
There’s also a charging harness sold by third party robotic mower shops, running around $25 to $50 depending on the seller, which covers the internal wiring between the tower and the mower’s docking contacts.
Wire connectors, couplers, and the splicer
This is where people get confused, because Husqvarna actually uses two different terms for two different jobs, and they’re not interchangeable even though they look similar.
The Automower Connector is what links your boundary wire directly to the charging station’s metal pins inside the tower. You open it, insert the wire, and close it with pliers, leaving about 1 to 2 cm of wire sticking out above the connector once it’s closed.
The Automower Coupler (also called a splicer) is a different tool entirely, meant for joining two sections of wire together out in the yard, whether you’re repairing a break or extending your boundary into a new area. It works with three holes at the bottom where you push each wire end in, then press the coupler shut with pliers, starting in the middle and working out to the sides. If you’re using Husqvarna’s Heavy Duty Reinforced wire, you’ll need to peel back both the outer black layer and the white mesh underneath before the wire fits properly into the coupler.
There’s also a separate connector clip (part 501980201) used specifically to join a guide wire into an existing boundary wire, which is its own small piece distinct from both the connector and the coupler above.
Couplers typically get sold in bulk, a hundred piece pack is common from parts suppliers, since installers tend to burn through several during a single boundary wire setup or repair job.
Guide wire and boundary wire itself
The 115H uses the same wire type for both its boundary and guide runs, and Husqvarna sells it as a 20 meter (about 65 foot) low voltage spool under part number 579825101 for connecting the transformer to the charging station. Separate boundary and guide wire spools for the actual perimeter and pathway runs are sold in much longer lengths, often 400 to 450 meters, since that’s roughly what covers a typical residential install.
If you’re extending an existing setup rather than starting fresh, match the wire gauge to what’s already in the ground. Mixing wire types across one continuous loop can cause signal inconsistency, which usually shows up as random loop errors that have nothing to do with an actual physical break.
Power supply and low voltage cable
The power supply unit that plugs into your wall outlet and feeds the charging station is sold separately too, generally priced between $180 and $200 for the genuine Husqvarna version. This same unit also covers the 315X and EPOS reference station setups, so it’s a shared part across a few different models.
For the low voltage cable itself (the one running between the power supply and the charging station), original kits ship with lengths anywhere from 16 feet up to 5 meters depending on which bundle you bought. If your outlet sits farther away than that, aftermarket extension cables are widely available and compatible, just make sure whatever you buy is rated for outdoor, buried use, since this cable often ends up staked into the ground alongside the boundary wire.
Where genuine parts matter and where they don’t
Husqvarna is upfront that using non genuine parts can lead to fit and compatibility problems that cause premature wear or malfunction, and that’s a fair warning for anything touching the cutting system or the electronics inside the charging tower. Blades, screws, and the cutting disc are cheap enough and critical enough to safety that it’s not worth cutting corners there.
Wire, connectors, and couplers are a different story. As long as the gauge matches and the connector type fits Husqvarna’s pin layout, third party wire and couplers work fine for most home installs, and that’s usually where you’ll save the most money compared to buying everything through the official spare parts shop.
If you’re dealing with a docking issue rather than a part that’s visibly broken, our guide on charging station placement walks through the setup side of things, since a lot of what looks like a parts problem is actually just a positioning issue.
FAQ
What wheel assembly fits the Husqvarna Automower 115H? The official wheel assembly is listed under Husqvarna part number 591 20 36 dash 02, sold as a two piece kit. Third party sellers also offer the front wheel assembly on its own for around $33, and a combined wheels motor kit that covers both the 115H and 315X models.
What battery does the Automower 115H use? It runs on an 18 volt, 2.0 amp hour, 36 watt hour battery under OEM number 593 24 72 dash 01. The same battery also fits the 305, 310, and 315 models, and it’s specifically meant for units built from a certain serial number range onward, so check your serial plate before buying.
What’s the difference between the Automower connector and the coupler? The connector links your boundary wire directly to the pins inside the charging station tower. The coupler (also called a splicer) is used out in the yard to join two separate wire ends together, whether you’re repairing a break or extending the boundary into a new area.
How often do I need to replace the cutting disc and blades on the 115H? Blades typically need replacing every couple of months during active mowing season, while the cutting disc itself lasts much longer and only needs replacing if it’s cracked or physically damaged rather than just worn from normal blade wear.
Can I use third party wire and connectors instead of genuine Husqvarna parts? For wire, connectors, and couplers, yes, as long as the gauge and connector type match Husqvarna’s specifications. For anything in the cutting system or the charging tower’s internal electronics, genuine parts are worth the extra cost since fit problems there tend to cause bigger issues down the line.
Is the charging tower on the 115H repairable if the circuit board fails? No. Husqvarna notes the charging tower isn’t a serviceable unit internally, so a failed circuit board means replacing the entire tower rather than swapping just the board.
What length is the standard low voltage cable that ships with the 115H? It varies by kit, ranging from about 16 feet up to 5 meters. If your power outlet sits farther away than that, aftermarket extension cables rated for outdoor and buried use are widely compatible.
Does the 115H use the same wire for both boundary and guide wire? Yes, Husqvarna recommends using the same wire type throughout the entire installation, covering both the boundary loop and the guide wire that leads the mower back to its station.
Where can I find official part numbers for my 115H? Husqvarna’s official spare parts catalog and illustrated parts list, searchable by entering your mower’s model number, breaks every component down with its specific OEM part number and diagram.
Should I always replace the screw when I replace a blade? Yes. Blades and screws are designed to be replaced together, since pairing a new blade with an old, worn screw throws off the balance of the cutting disc and leads to an uneven cut.
