Disclosed embodiments include power machines (e.g., 100; 200; 300) and relatedstructures of lift arms (e.g., 230; 330),implement carriers (e.g., 272; 372), follower links (e.g., 375), and driverlinks (e.g., 380) which improve manufacturability, reducecomponent failures, and improve power machine design and functionality. Insome embodiments, lift arm structures include cast lowerlift arm portions (e.g., 339). The cast lower lift arm portions includecontoured upper ends (e.g., 405) which are sleeved onto contouredlower ends (e.g., 410) of upper lift arm portions (e.g., 333) to controlstress points and to reduce stresses on welds. The follower linkstructures can include follower links which are configured to be positioned atleast partially outside of the lift arm structure to improverear visibility. The driver link structures can be configured to be laterallyoverlapping with innermost surfaces (e.g., 680) on the liftcylinder (e.g., 338), but configured such that as the lift arm is raised thelaterally overlapping portions are moved above the innermostsurfaces of the lift cylinder.
