Beyond the chapter structure, this Krone Big Pack 120-70 manual delivers the kind of operational depth that only a manufacturer-issued document can provide. You get the complete working method of the baler explained from the pick-up through the feed rake, pre-compression chamber, baling ram, and knotter, including the specific behaviour of the MultiCut cutting system with its blade control shaft, blade protection system, and selectable cutting lengths. The comfort control section walks through the electronic bale density regulation, sensor testing, alarm code interpretation, and valve checking — all from the operator’s seat. The settings chapter is particularly valuable for anyone maintaining these machines long-term: needle adjustment in three dimensions, twine bar positioning, baling ram clearance, rake timing, and sensor gaps are all covered with dimensions and step-by-step instructions.

Safety is threaded throughout the document, beginning with the general safety and accident prevention regulations and continuing through machine-specific warning signs. The maintenance chapters cover gearbox oil specifications and change intervals for every gearbox on the machine, hydraulic system care, compressed air unit servicing, tyre pressures, and the central lubrication system. The fault-finding chapter uses a combination of tables and knot diagrams to help diagnose the most common baler problems — from missed knots and twine breakage to rake jams and electronic control failures.

What This Manual Enables You to Do

With this Krone Big Pack 120-70 and 120-70 MultiCut operating manual, you can:

• Set up the baler correctly from initial attachment through to first bale, including drawbar height adjustment, PTO shaft adaptation, and hydraulic connection identification
• Operate the comfort control system with confidence — adjust bale density for different crops, read alarm messages, test sensors, and check valve function
• Adjust and maintain the knitter mechanism, including needle positioning, twine bar setting, knotter hook tension, and blade lever alignment
• Service every gearbox on the machine with the correct oil grades and quantities
• Diagnose and fix common faults using the systematic fault tables and knot diagnosis diagrams
• Configure and maintain the MultiCut cutting system, including blade changes, cutting length selection, and blade protection settings
• Prepare the machine for winter storage and bring it back into service safely the following season

Why This Manual Matters

Large square balers are complex, high-throughput machines where incorrect settings don’t just reduce bale quality — they can cause serious mechanical damage, premature wear, or unsafe operating conditions. The Krone Big Pack 120-70 operating manual gives you the manufacturer’s own procedures and specifications, so you’re not guessing at clearances, pressures, or torque values. The comfort control electronics, in particular, require an understanding of how the density regulation, sensor feedback, and hydraulic valves interact; this manual explains that relationship clearly. For the MultiCut cutting system, the manual details the blade control shaft positions for different cutting lengths and explains how to set the blade protection system for varying crop conditions.

Who This Manual Is For

This PDF is intended for owners, operators, farm mechanics, and agricultural service technicians working with Krone Big Pack 120-70 and Big Pack 120-70 MultiCut balers. It assumes a basic familiarity with agricultural machinery but does not assume prior experience with this specific model. The operating instructions are detailed enough for an owner-operator to perform routine maintenance and adjustments, while the technical depth in the settings and fault-finding chapters supports professional repair work.
