Zetor 3320, 3340, 4320, 4340, 5320 1996 Operators Manual

If you own a Zetor from the 3320 through 5320 series and you are working off a photocopy or some aftermarket translation, you are asking for a headache. I have seen guys misread hydraulic flow ratings because the numbers didn’t match the factory plate. That costs you a pump rebuild at minimum. This is the real 1996 Operator’s Manual – 260 pages, original OEM print, from the factory in Brno. It covers every model listed: Zetor 3320, 3340, 4320, 4340, 5320. Do not confuse it with a generic “repair manual” or a sloppy PDF scan. This is the exact document that came with the tractor when it was new. You need it for operation, daily checks, and basic maintenance. Not a service manual for engine overhauls – that is a separate book. But if you want to run the tractor right and avoid breaking something because you guessed at a torque or fluid spec, this is your starting point.

What This 260-Page Operator’s Manual Covers

The table of contents runs from serial number locations on page 9 all the way to an informative list of machines for aggregation on page 255. Between those, you get the important safety instructions for user (page 11) and the daily preventative maintenance checklist on page 15. The manual walks you through machine operation, utilization for transport, power drive of agricultural attachments, hydraulic system, three-point hinge, and usage of front and rear axles. There is a dedicated section on adjustments starting at page 129, then tractor maintenance from page 155, and a full lubrication chart of Zetor tractors listed on page 117. Electrical installation details begin on page 165. For the Horal models (5340 HORAL, 6340 HORAL) there is a specific section on page 179, and an inclinometer section on page 180. The main performance data tables run from page 187 to near the end. Every procedure is written for the operator, not a factory technician, so the language is direct. But it still expects you to use tools correctly and follow the sequence.

Daily Preventative Maintenance – Page 15 Specifications

Page 15 of this manual gives you the daily checks you have to run before you crank the engine. Fluid levels, tire pressure, belt tension, loose hardware. I have seen tractors come into the shop with a blown head gasket because the owner skipped checking the coolant level for three days. That is a $2000 mistake right there. The manual lists everything in a checklist format. You check the engine oil, transmission oil, hydraulic oil, power steering fluid, and brake fluid. It also tells you to inspect the tires for damage and check the wheel bolt torque. Speaking of torque – this manual does not give you every fastener spec, but it does include the important ones for wheel bolts and a few critical connections. For a full torque table, you need the service manual. But for daily operation, page 15 keeps you out of trouble.

Hydraulic System and Three-Point Hitch: Factory Steps

The hydraulic system section starts at page 69 and covers the pump, control valves, and remote outlets. Page 78 handles the three-point hinge – that includes the lift arms, stabilizers, and the top link adjustment. The manual tells you the correct procedure for attaching implements and setting the draft control. Do not skip the part about the “position control” vs “draft control” modes; I have seen guys bend a lift arm because they left it in draft while running a heavy rotary cutter. The manual also explains the power drive of agricultural attachments (PTO) – that is on page 63. It gives you the PTO engagement sequence and the correct shaft speed for each model. If you need to replace a seal in the hydraulic pump, you need the service manual. But this operator’s manual will keep you from burning up the pump by running low on oil.

Lubrication Chart: Page 117 Fluid Capacities

Page 117 contains the lubrication chart for the entire Zetor tractor range. It lists the oil type, viscosity grade, and capacity for the engine, transmission, hydraulic system, front axle, and final drives. All in imperial units where applicable (quarts, pints). It also shows the grease points for the front axle pivot, steering knuckles, and PTO shaft. If you are using the wrong weight oil because a forum told you “it’s fine,” stop. Get the factory chart. The manual also includes tire inflation pressures on the performance data pages (page 187 onward). For the 5320 model, the front tire pressure spec is different from the 3320 because of the weight difference. The manual breaks it down.

Who Should Use This Manual?

This manual is for the owner-operator, the home garage mechanic, or the small farm guy who does his own service. If you are a professional tech working on these tractors, you still need this manual for the daily check specs and the hydraulic flow diagrams. But your main tool will be the service manual. The operator’s manual gives you the safe operating limits, the break-in procedure for a new or rebuilt engine, and the proper way to load the tractor for transport. If you are a beginner with tractors, start here. Do not jump straight into a repair manual. Learn the daily routine first. It will keep you from doing damage before you even start a job. The manual also covers the [Manual Transmission] operation (pages 43-56) including clutch adjustment and gear shifting patterns. For transmission internal overhaul, you need the parts catalog: Zetor 3320 3340 4320 4340 5320 Tractor Parts Catalog 2002 and Zetor Spare parts Catalog 2003 give you all the exploded views and part numbers. The larger models have their own catalog: Zetor Major 3320-7340 2002 Parts Catalog. For external reference on how a [Manual Transmission] works in general, you can check Wikipedia, but for this tractor’s specific shift linkage adjustment, use the factory procedure in this manual.

OEM Documentation vs Aftermarket Reprints

I do not trust aftermarket manuals. I do not care if they say “copied from original.” They always miss a page or the torque values got rounded off by a careless scanner. This file is the original OEM PDF from the factory. It has Zetor’s own part number and the 1996 date. The hydraulic diagrams, the electrical schematics (page 165), the valve clearances – they all come from the same source as what the dealer would pull up on their terminal. You do not guess with a 5000-pound machine. You use the factory data. Period.

Frequently Asked Questions

Does this manual cover the 5340 and 6340 HORAL models?

Yes. Pages 179-180 are dedicated to the ZETOR 5340 HORAL and 6340 HORAL, including the inclinometer section.

Are torque specs included for cylinder head bolts?

No. This is an operator’s manual, not a service manual. It covers daily checks and basic maintenance. For head bolt torque, get the Zetor factory service manual.

Where do I find the correct tire pressure for my 4320?

The main performance data tables starting on page 187 list tire pressures in PSI for each model. Look up your model number and front/rear tire size.

Can I use this manual to rebuild the hydraulic pump?

No. The hydraulic section (pages 69-84) only covers operation, adjustment, and minor troubleshooting. Rebuilding the pump requires the service manual and the parts catalog Zetor 3320 3340 4320 4340 5320 Tractor Parts Catalog 2002 for exploded views and seal part numbers.

If you are running a Zetor 3320, 3340, 4320, 4340, or 5320 from the 1996 model year, this is the exact document that should be in your glovebox. Stop relying on a faded photocopy or a forum post. Access the Factory Manual today and have the correct procedure for every daily check and adjustment.
