The Extra Tractor Slot is an Item that can only be found in the form of Golden Pupa loot. Upon being picked up, players will be able to store two Tractors instead of the usual one. This can effectively allow players to not have to pick and choose between which Tractor they desire to hold. Likewise, the player can hold two of the same Tractors if they wish to reap the benefits of that type of Tractor even more. Note that if a Recharge Mushroom is picked up it will only benefit the currently equipped Tractor, not both.
Compared to other Items related to Tractors, the Extra Tractor Slot is the only one that allows the player to store multiple Tractors, limiting how often players will need to choose which Tractor to hold. In addition, this perk can technically provide more Tractor usages over the course of the run, since both Tractors recharge independently. In regards to charges-per-Tractor ratio, this idea is amplified if two of the same Tractors is held.
The following is a list of possible Items that can affect Extra Tractor Slot:
- Air Freshener
- Backup Generator
- Double Cream
- Fertilizer Fuel Converter
- Shroom-mates (partially, given Recharge Mushroom has been unlocked)
- Recharge Mushroom
- Whiskey Shot
