Resumen del manual
If any assistance or addi- tional information is needed, contact your authorized Bush Hog dealer. Bucket 1-2 DESCRIPTION The Models 2427 and 3227 Front End Loaders are designed for two wheel drive tractors. The Models 2447 and 2847 Front End Loaders are designed for two wheel and four wheel drive tractors. They come equipped with parking stands to support the loader so the tractor can be “driven in” for quick attachment and a bucket level indicator that allows operator to gauge bucket position when the bucket cannot be seen. Available attachments include buckets for lift- ing loose materials; a bale spear for lifting round hay bales; and a fork lift for palletized material. All opera- tions should be conducted within the loader limits specified in Table 1-1. IMPORTANT This manual covers four different models of front end loaders. There will be minor differences in configuration and appearance of some components. However, the basic assembly and operation of the different models will be the same. All references made to right, left, front, rear, top or bottom is as viewed facing the direction of travel with implement properly attached to tractor. 8 Table 1-1 TECHNICAL SPECIFICATIONS GEJCBAHFXXZZWXYZUVVV SERIES LOADER 2427QT 2447QT 2847QT 3227QT A.
