Part of the Kubota Operator Manuals.
This is the Kubota BH70 backhoe operator manual, a 39 page PDF (publication 7K506-7991-1) for owners and operators of the BH70 attachment. It covers safe operation, backhoe specifications and terminology, pre operation checks, every control, scheduled maintenance, and the complete removal and reinstallation procedure.
The specifications section gives real figures, including a maximum digging depth of 2197 mm (86.5 in.) and 180 degree bucket rotation, so you know the machine's working range.
With this manual you can learn the boom, swing, dipperstick and stabilizer levers, run the daily and 50 hour maintenance checks, torque the sub frame mounting bolts to spec, and safely detach or remount the backhoe on the tractor when switching between jobs.
