Page 4: Introduction
1. INTRODUCTION Intended use POTILA MASTER seedbed cultivators are intended for preparing seedbed in either the spring or fall. The field can be ploughed or cultivated, and it can contain straw or other plant parts. The seedbed cultivator is used for loosening and crumbling the soil after primary tillage to produce a level seedbed and well-crumbled topsoil. - Page 5 Technical specifications Type MASTER Number of sections Working width, m Number of tines Number of tine axles Draught requirement, kW Number of required hydraulic outlets single-/double-acting Transport width, m Working depth control M = mech.

2. SAFETY GUIDELINES Warnings Pay special attention to all instructions and diagrams marked with this symbol. Read the manual carefully and make sure that you understand everything. All safety guidelines must be read carefully before hitching the seedbed cultivator to the tractor. Learn how to operate the cultivator carefully and in a correct manner. - Page 8 Wear safety goggles when performing maintenance. Wear hearing protectors when driving. Instructions for the operator - Never stay near the wing sections when they are in the raised position. - Do not allow anyone to stay on the seedbed cultivator when it is being used or transported.
- Page 9 Transport on roads • Slowly raise the wing sections fully into the transport position. They are controlled with the same hydraulic valve as the frontboard during harrowing. • Ensure that the automatic locking bars lock into their holes and do not drive off before both wings are locked.

Page 11: Setting-Up
3. SETTING-UP Always observe the tractor's safety guidelines when hitching or unhitching the seedbed cultivator. Crushing and cutting hazard when hitching or unhitching the seedbed cultivator. Never disconnect or connect hoses that are under pressure. Raising/lowering the draw bar The draw bar of the seedbed cultivator can be raised to reduce the space needed for storage (for example, in winter storage). - Page 12 Hitching and hydraulics Always observe the tractor's safety guidelines when hitching or unhitching the seedbed cultivator. Crushing and cutting hazard when hitching or unhitching the seedbed cultivator. Never disconnect or connect hoses that are under pressure. • Hitch the cultivator to the tractor tow hook only. •...
- Page 13 • Open transport valves A. (The figure shows the valve in a open position.) • Lift the cultivator on its wheels. • Drive the tractor with the hitched cultivator onto a firm, level surface. • Lower the wing sections. Ensure that the wing section extension areas are clear! For this procedure, the cultivator must be in the transport position.
- Page 14 Adjusting the seedbed cultivator NOTE! Ensure that the wing section extension areas are clear. Remember the minimum safe distances! Lower the wing sections as follows: • If the cultivator is not in the transport position, lift the cultivator all the way up on its wheels. (The change valve will then direct the pressure to the wing section lift cylinders.) •...
- Page 15 MIDDLE SECTION AND WING SECTION ADJUSTMENT: • The height of the middle section is aligned with the height of the wing sections by turning end piece of midle cylinder. • When the end piece is extended, the middle section rises. Correspondingly, when the end piece is retracted, the middle section lowers in relation to the wing sections.
- Page 16 WHEEL HYDRAULICS AND DEPTH CONTROL Valve A-A The hoses for the wheel hydraulics control circuit are marked with red. Valve B-B The hoses for the depth control circuit are marked with blue. The working depth is controlled hydraulically: • Check that the hoses are properly connected (+/–). Connect the hoses marked with the same colour to the same tractor valve.
- Page 17 Working depth indicator POTILA MASTER seedbed cultivators are equipped with a working depth indicator which indicates the depth in centimetres. Adjust the indicator as described below. The indicator is set to 0 at the factory, indicating the position in which the tines and wheels are at the same level.
- Page 18 Use of the rear equipment The tractor must be shut down and the parking brake must be applied when adjusting the rear equipment. The position of the following harrow can be adjusted at points E and F. On clay soil, the following harrow most effectively turns fine soil to the right sowing depth if the tines are nearly perpendicular to the ground and...
- Page 19 Troubleshooting/FAQ Hydraulic control is not working: • Check that there is no pressure in the hoses before connecting them to the tractor. • Check that the hoses are connected to the tractor. • Check that the hoses are connected to the correct connectors in pairs.

4. HARROWING General The S-tine cultivators are intended for producing a level seedbed. Normal working depth for cereals is 0–6 cm. Because the seedbed cultivator is adjusted at the factory on a level surface, more accurate adjustments must be made on the field (the soil type, sinking of the tractor wheels and other factors have an influence on the settings). - Page 22 5.

5. MAINTENANCE Observe the safety guidelines specified in Section 2 when performing maintenance. - Shut down the tractor before performing any maintenance procedures. - Support the cultivator with jack stands when performing maintenance. - Do not stay on the cultivator. Key values Tyre pressures: 200/60-14.5... - Page 24 Winter storage: • If the cultivator is to be stored for a longer period of time, clean and lubricate it thoroughly. If a high-pressure washer is used for cleaning, do not aim the water jet directly to the cylinders, bearings and stickers. •...

- Page 26 Tine Replacing a tine A tine must be replaced if it is broken. Open the tine mounting bolt and remove the old tine. Leave the bolt in the tine clamp and insert the new tine into the clamp. Pull the tine backwards so that the bolt contacts the tine axle. Tighten the nut to 110 Nm.
- Page 27 Bogie beam Checking the bogie beam bearing • Check the clearance of the bogie beam bearing before lubrication. • Extend the cultivator on a level surface. • Lower the cultivator on its tines so that the wheels lift off the ground. Push the rear wheel so that the front wheel is off the ground.
- Page 28 Wheel hub • Check the bearing clearance before lubricating the hubs. • Extend the cultivator. • Lower the cultivator on its tines so that the wheels lift off the ground. • Hold the wheel firmly and feel for play: the wheel must rotate easily without perceptible play in the bearing.
- Page 29 Hydraulics The working depth of MASTER seedbed cultivators is controlled hydraulically. The cylinders for frontboard hydraulics and wheel transport hydraulics are connected in series, ensuring that all functions controlled by these cylinders take place accurately at the same rate.
- Page 30 Change valve The change valve assemblies control the hydraulics for the frontboard and wing sections. Their purpose is to distribute the pressure of the same hydraulic outlet to the frontboard cylinders or wing section lift cylinders depending on the position of the cultivator (work or transport position).
- Page 31 Disassembling the valve Open the bolts of the lever assembly and remove the levers. • Open the body bolts. • When disassembling the valve, pay attention to the markings • in the valve stem! Mark the oil channel directions on the valve stem to the valve •...
