Best Nikkes
Harvester is an easy boss. You just need to destroy the Head as soon as possible and focus on maximizing your damage while surviving against the continually spawning horde of Raptures and destructible projectiles (like a pressure test). Ideally, have 1 Water Nikke for its Elemental QTE.
Against Harvester, Water Nikkes will have their damage boosted a lot if they have Elemental Damage bonuses (from OL & other sources), so investing in Top-Tier Water DPS is the best option for this fight.
If you lack all of the teams below, a team without a Water Nikke can work because Water QTE only happens 2 minutes into the fight. Or, just use Privaty as your FLEX Nikke and run your ‘generic’ main team.
Snow White: Heavy Arms: The best Water DPS. 
Dorothy: Serendipity: One of the best Water DPS but heavily dependent on Tove (Treasure). She, being a summer-limited unit, is only obtainable during a certain period of the year. 
Crown: The best general Burst 2 Nikke. She provides a shield against the Harvester’s lasers. 
Anis: Star: The best general Burst 1 CDR. She provides burst gen. She also helps with clearing mobs. 
Elegg: Boom and Shock: Decent flex in the Water team. She offers elemental damage buff and screen-wide skill damage. If she is invested, consider Bursting her once at the end of the battle, or additionally once more after she obtains max ghost stacks without wasting your main DPS Burst. Her ghosts can affect the mobs, so make sure to kill the mobs before Bursting. 
Mast: Romantic Maid: One of the best general flex. Burst Maid Mast every third burst (Crown → Crown → Mast). 
Helm (Treasure): Decent Water bossing DPS and great buffer. She offers burst gen, buff and increases Crown S2 uptime. However, her Burst prioritizes mobs starting Stage 4 and above, so make sure to kill the mobs before Bursting. 
Privaty (Treasure): Decent Water DPS and great buffer. 
Siren: Great Burst 1 CDR. She does decent damage output while offering burst gen to the team. She also helps with clearing mobs. Use Siren if you do not have Anis: Star. She gets easily one-shotted by Harvester. 
Nayuta: One of the best general Burst 2 Nikke. She helps with clearing mobs during her Burst. She gets easily one-shotted by Harvester. 
Anchor: Innocent Maid: Great Burst 2 Nikke paired with Maid Mast. She provides HP storage, which allows to tank Harvester’s lasers. Crown and Nayuta are better choices over her for whole team damage. 
Rapi: Red Hood: Great neutral Burst 1 or Burst 3 DPS. Since she is built universally, she can fill your Harvester team until you get a proper Harvester team. Do not use Rapipi as Burst 1 when using both Bready and Liberalio.
Ludmilla: Winter Owner: Decent Water DPS and great buffer. She can be used as Bursting DPS or off-burst.
Quency: Escape Queen: Great Water DPS on open core. 
Bready : Great Water DPS. She easily clears the mobs around Harvester with her Distributed Damage. However, she needs a sustained damage buffer or a distributed damage buffer in her team to function. Not recommended to use her without Maid Mast. 
Liberalio : Great neutral DPS on core. She is the best CS buffer to buff Bready. If you are using Liberalio with Bready, do not bring a third Burst 3 Nikke.
Best Teams
Here are some example teams you can try:
Spider Slayer Mode: Anomaly - Harvester || Element: Water This team chews through Harvester AI like Snow White seeing a fat worm. Snow White will take care of the pesky mobs and solo kill Harvester herself. Crown may be replaced with Anchor: Innocent Maid or Nayuta. Snow White went wandering Mode: Anomaly - Harvester || Element: Water Bready can kill all mobs while outputting great damage, but she needs Mast : Romantic Maid to be worth considering. Crown may be replaced with Anchor: Innocent Maid or Nayuta. Characters

Burst Maid Mast every third burst (Crown → Crown → Mast).
If Maid Anchor is used, burst Maid Mast with the stronger DPS. Substitutions
Anis: Star may be replaced with Siren or Rapi: Red Hood.
Snow White: Heavy Arms may be replcaed with Dorothy: Serendipity or Cindrella: Crystal Wave.
Helm (Treasure) may be replaced by Privaty (Treasure).
Mast: Romantic Maid may be replaced by Privaty (Treasure) or Elegg: Boom and Shock. Characters
About the team
Burst Maid Mast every third burst (Crown → Crown → Mast).
If Maid Anchor is used, burst Maid Mast with the stronger DPS. Substitutions
Anis: Star may be replaced with Siren or Rapi: Red Hood.
Liberalio may be replaced with Cinderella: Crystal Wave or Rapi: Red Hood.
No Pilgrims vs Spider Mode: Anomaly - Harvester || Element: Water Beginner friendly team. Maid Duo being water helps team-building in the early-game. This team will preform worse than the Bunny Ade version of the Spider Slayer team if you have 2 invested Water DPS and Summer Elegg. Liter may be replaced with any B1 CDR.Characters

Boss Fight Breakdown
Harvester is a very simple boss. In short:
It has a Head part. It can be destroyed by doing enough damage. Otherwise, it automatically gets destroyed after the first QTE.
After the Head is destroyed, the boss has a permanently exposed core for the rest of the fight. Because core improves damage, always destroy the Head ASAP, but don’t die.
Harvester spawns mobs throughout the fight that hurt and fire destructible projectiles (rocks) in the latter half.
If too many mobs are kept alive, Harvester does massive AoE damage to your team.
If you are looking for the full breakdown, Harvesters' ATK increases pretty steadily from Stage 4 to Stage 8, and its DEF increases by a negligible amount.
Harvester deals increased damage to Wind Nikkes:
300% at Stages 1~3
400% at Stages 4~6
500% at Stages 7~9
Harvester has a Head. Destroying it stuns the boss (if done before QTE) and permanently exposes the core for the rest of the fight. Depending on when you destroy the Head, the boss exhibits two different behaviors for the rest of the fight, but it’s hard to replicate the method to activate the second one, so we will only include the most common one here.
Mob Spawn
Mobs spawn throughout the entire fight except during QTE
Vulcan: Fires special bullets at a single Nikke. The Nikke who is hit cannot move or attack for a certain period of time. This might cause damage loss if it hits your DPS Nikkes or halts Burst rotations. Avoid getting stunned.
Oculus: Fires special bullets at a single Nikke. The Nikke who is hit cannot move or attack for a certain period of time. This might cause damage loss if it hits your DPS Nikkes or halts Burst rotations. Avoid getting stunned.
Glitter: Fires a suicidal attack at a single Nikke. A warning sign is shown on the target of the attack.
Cricket: Launches pinpoint attacks on a single Nikke at long range. A warning sign is shown on the target of the attack.
Remnant: Fires a suicidal attack at a single Nikke. A warning sign is shown on the target of the attack.
During the fight, Harvester cycles between 3 main attacks:
Fires guns at a random Nikke. They can be blocked by cover or taunted.
Shoots a laser at a random Nikke. It can be blocked by cover or taunted. A warning sign is shown on the chosen target before the attack (be careful, as Remnant, Glitter, and Cricket also show a warning sign on their target before attacking).
Shoots multiple destructible rocks/balls. They can be intercepted or i-framed.
At around 2:20~2:10 and 0:20~0:10 seconds left in the fight, Harvester exhibits different behavior depending on some conditions:
The Head is destroyed and most mobs are dead: Harvester gets stunned.
The Head isn't destroyed, and most mobs are dead: Nothing happens.
A lot of mobs are not killed: Harvester fires a strong AOE attack. This attack kills all on-screen mobs.
Halfway through the fight, Harvester puts up 2 QTE:
No mobs spawn during QTE.
During the first QTE, 6 Grey Circles spawn in an order, then Red Circles will appear following the same order. Failing to destroy all 6 Red Circles results in a team wipe. The Head gets destroyed after successfully passing this QTE. It can be hard to destroy it without full-burst or Little Mermaid focus fire.
Then, another QTE shows up. This time, it only has Red Circles, but only Water Nikkes can destroy them. Failing to destroy results in a team wipe.
After QTE, the rest of the fight goes back to normal.
Tips
Destroy the Head ASAP to be able to access the core quickly for damage.
- Helm (Treasure)’s Burst targets mobs instead of the boss later on in the fight, so you should kill all mobs before Bursting with her to avoid taking damage. Elegg: Boom and Shock’s Burst might also hit mobs; kill them first before Bursting at the end of the fight.
You’ll want to kill the mobs (and destructible projectiles) throughout the duration of the fight for survival. Nikkes like
Siren and Nayuta can do this passively. You can use pause tech to kill the mobs and the QTE to avoid wasting time shooting the sky.
