Height compensating loader implement tool level indicator

Abstract

A bucket level indicator mechanism for use with work machine with a front mounted loader implement includes a carriage assembly having a carriage frame comprising a carriage back and first and second carriage endplates at longitudinal ends of the carriage back, a first end of the carriage assembly being pivotably connected to one of the masts, wherein the carriage back has a slot formed therein along a portion of its longitudinal length. At least one guide rod extends between the carriage endplates. A boom height compensating link is mounted on the upper arm section. The boom height compensating link has at least one fixed traveler configured to be received in the slot in the carriage back, the carriage assembly being mounted so as to slide relative the traveler, wherein as the loader boom is raised and lowered by extension or retraction of the lift actuator, the carriage assembly rotates relative the mast about a pivot as the traveler slides in the slot in the carriage back. A twisted strip extends between the carriage endplates supported by the carriage assembly configured to rotate relative the carriage endplates. A sliding indicator nut rides on the at least one guide rod such that the sliding indicator nut may move along the longitudinal axis of the carriage assembly but is prevented from rotating relative the carriage assembly, wherein the indicator nut has a center aperture that receives the twisted strip and permits longitudinal movement of the nut relative the twisted strip along an axis A of the carriage assembly, but prevents angular movement of the portion of the twisted strip that engages the nut relative to the nut, wherein the nut is driven along the axis A of the carriage assembly by a linkage that is connected relative the bucket such that the nut reflects the level position of the bucket.
