Claim 1
Independent Claim
201 words
Apparatus for bale handling including a slack adjustor comprising: (a) a bed mounted on a frame; (b) means for picking up a bale and depositing said bale on said bed, said means having a first width; (c) means for adjusting said first width; said means for adjusting including a first portion, a telescoping second portion slidingly engaged with said first portion, and a pin removably inserted in selected ones of a plurality of matched holes in said first and second portions; (d) a pivotal pickup arm connected to said second portion; (e) means for hydraulically pivoting said arm, said means being a hydraulic cylinder; (f) a source of hydraulic fluid; (g) means for conducting hydraulic fluid from said source to said cylinder, said means being at least one slack high pressure hose; and (h) means for adjusting slack in said hose to correspond to the adjustment of said second portion relative to said first portion, said means for adjusting slack including a base portion connected to said means for picking up a bale and a loop-like portion connected to said base portion to encircle said at least one slack high-pressure hose and retain the position thereof relative to said base member.
