Abstract: Some embodiments of a gearbox for an irrigation system can comprise a housing, a worm gear within the housing, a bull gear within the housing and configured to be engaged with the worm gear, a diaphragm, and a vent. The diaphragm can define a chamber configured for expansion and contraction and configured to be positioned inside the housing to relieve pressure build-up within the housing. The vent can be configured to allow air to flow between the atmosphere and the chamber.

Abstract: A gearbox for an irrigation system can comprise a housing, a worm gear within the housing and a bull gear within the housing and configured to engage the worm gear. The housing can be configured to receive a removable cartridge. The cartridge can include a diaphragm and a vent. The diaphragm can define a chamber configured for expansion and contraction and configured to be positioned inside the housing to relieve pressure build-up within the housing. The vent can be configured to allow air to flow between the atmosphere and the chamber.
Abstract: A driveline coupler can have a pair of load arms that engage with an insert member between them. The load arms can be configured to couple to shafts in a drive assembly. At least one load arm can be adjustable to couple with different sized shafts. The at least one load arm can also self center different sized shafts including different sized shafts of similar shapes. The coupler can further have a center pin to align the coupler. A coupler with a center pin can further have a fixing member to lock the coupler in alignment.
