PREOPERATION 330 TRENCHER GENERAL INFORMATION The 330 Trencher mounts directly to the 3-point hitch system on your tractor the same as any other 3-point hitch attachment. HYDRAULICS The 330 trenchers are shipped with two 48” long hoses (with 6FJX ends) for connecting to your tractor’s rear remote hydraulic system.
PREOPERATION 330 TRENCHER NOMENCLATURE The purpose of this page is to acquaint you with the various names of the trencher com- ponents. This knowledge will be helpful when reading through this manual or when ordering service parts. MANUAL STORAGE TUbE...
INSTALLATION GENERAL INFORMATION The following instructions will help you to mount the trencher onto your tractor. The trencher uses the 3-point hitch system for ease of installation, therefore if you have ever in- stalled 3-point hitch equipment before, installing the trencher should prove no problem. Your tractor must be equipped with rear remote auxiliary hydraulics for trencher opera- tion.
Page 18
INSTALLATION Adjust the lower link anti-sway chains and center the trencher. Complete the hydraulic plumbing by connecting the hydraulic couplers together. NOTE: The auxiliary hydraulics on your tractor operates the trencher cylinder and is used to lower the trencher into the ground or raise it up for transport. WARNING! Escaping fluid under pressure can have sufficient force to penetrate the skin causing serious personal injury.
INSTALLATION Adjust 3-point lever upper stop to limit the travel to a point where trencher will clear the ground sufficient for transport and still keep at least 3" of shaft telescoped together. Start the tractor and raise the trencher boom UP. Operate the 3-point hitch lifts to de- termine if its capacity is sufficient and all points work properly.
INSTALLATION POWER (PTO) SHAFT ADJUSTMENT The trencher power (PTO) drive assembly may need to be shortened to fit up to your tractor correctly and to prevent the drive assembly from “bottoming out” and causing extensive damage to the tractor PTO drive assembly. FULLY RETRACTED .50” FREE TRAVEL The shaft assembly is shortest when the shaft is straight inline with the trencher. There should be a minimum of .50" of free travel before the shaft is fully retracted. To check: Lower the trencher until the shaft is parallel to the ground and is straight inline with the trencher gearbox. Check to see if there is a minimum of .50" free travel. If there is not at least .50" of free travel DO NOT OPERATE TRENCHER. NOTICE: IF THE DRIVE SHAFT “BOTTOMS OUT” BEFORE IT IS STRAIGHT INLINE WITH THE TRENCHER, STOP AND CALL YOUR NEAREST DEALER OR THE TRENCHER MANUFACTURER BEFORE TRENCHER OPERATION.
CONTROLS GENERAL INFORMATION Simplicity of operation is one of the key features of the 330 trencher. It is important to be familiar with, and know the controls and adjustments on both the trencher and the tractor. Such knowledge is crucial for safe, efficient operation of equipment. Take the time to learn how they operate now.
Page 22
OPERATING INSTRUCTIONS CONTROLS Lowering the trencher will cause the auger to lower, moving the spoil away from the trench. The auger should NOT be lowered to the extent that the auger itself starts to dig in the ground. This will greatly reduce efficiency. It should be noted that raising or lowering the trencher to change the auger height will also change the trencher depth.
Page 23
OPERATING INSTRUCTIONS CONTROLS FIGURE #2 SET SCREW JAM NUT CRUMBER BAR / PERSONAL RESTRAINT BAR MAINFRAME CRUMBER BAR TUBE CHAIN TENSION ADJUSTMENT Chain tension is maintained by a large spring located inside the boom and adjusted by moving the boom in or out. When trenching, the digging chain tension should be adjusted to that the chain is as loose as possible, without jumping off the sprocket or idler wheel.
Page 24
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS GENERAL INFORMATION The design of your trencher makes it relatively simple to use. With the help of the infor- mation in this section and a little practice you should become proficient in it's operation in no time.
Page 25
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS Mark off the area to be trenched out. This can be done with powdered line, chalk, or a guide string and stakes. Block off the area from others if possible. STARTING THE TRENCH Position the tractor with the trencher boom directly over the center of the trench layout.
Page 26
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS Slowly lower the digging chain into the ground to start the trench. Do this by lowering the trencher with the 3-point hitch arms. To begin trenching, always lower the 3-point hitch first, followed by the trencher boom using your tractor’s rear auxiliary hydraulic system. A combination of the 3-point hitch and trencher boom position will give the desired trench depth and spoil placement.
Page 27
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS Raise the trencher so that the auger rides above ground level to leave the spoil beside the trench. The high the auger the closer to the trench the spoil will be placed. See Figure #8. TRENCHER FIGURE #8 AUGER...
Page 28
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS Also the shorter the boom length the sharper the possible turn. Remember, the greater the increase in boom angle the higher the unit will have to be raised out of the trench to keep a unified trench depth.
Page 29
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS FIGURE #11 1st TRENCH TOP VIEW 2nd TRENCH RECOMMENDED DIGGING ANGLES A 90° digging angle is recommended for use in rock and frost conditions, and when trenching sharp corners. The 90° angle reduces excessive side pressure on the boom and digging chain when trenching corners.
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS After you have gone as far as you can without contacting the sidewalk, drive the tractor forward to clear the sidewalk and remove the trencher from the trench. Line up the unit on the other side of the walk and continue to trench as described previously until the two trenches are connected.
Page 31
OPERATING INSTRUCTIONS OPERATING TECHNIQUES 3-POINT HITCH TRENCHERS TRANSPORTING THE TRENCHER When transporting the trencher, remember to keep the trencher as low to the ground as is practical. The lower the trencher rides, the more stable the tractor will be. You do not want the trencher so low that the digging teeth touch ground in rough terrain.
DIGGING CHAIN OPTIONS GENERAL INFORMATION This section is devoted to digging chain options for your trencher. In it you will find a listing of all the chain options available. You will also find information on replacement parts, chain assembly, and chain conversion. These options will increase the flexibility of your equip- ment, and make your trenching job easier. There is some basic information about the trencher and it's digging components that you should know before you try to order any options. This information is given here for your convenience. With it you will be able to better understand the rest of this section. CHAIN PITCH The digging chains are divided into groups by pitch. The pitch of the chain is the dis- tance between the centers of the holes in the chain links (See Figure 1). The word pitch can also be used to describe the length of the chain.
Page 34
DIGGING CHAIN OPTIONS DIGGING STATIONS Digging chains are made up of a series of individual links pinned together. Every link has a special "Digging Station" link. These links are designed so that the digging teeth can be attached to the basic chains (See Figure 4). Digging chains may be purchased in any length, with or without teeth. All chains, teeth, spacers and assorted digging hardware may be pur- chased separately. FIGURE #4 DIGGING TOOTH MOUNTING HARDWARE DIGGING STATIONS DIGGING CHAIN CONVERSION KITS Digging chains can be modified to dig trenches in a variety of widths. By modifying an existing chain, it can be used to dig the width you want and thus save going the expense of a whole new digging chain assembly. This can be a considerable cost savings, however it is more work than just installing a new digging chain assembly. Contact your nearest dealer or the manufacturer to inquire on the conversion kits available for your trencher. It should be noted that this information only applies to modifying chains of the same length and pitch. All components must be of the same pitch. You cannot intermix components of dif- ferent pitch. This completes the basic information on digging chain options. The rest of this section contains specific information on digging chains and parts available, complete with part num- bers. Again it may be noted that these options are designed to increase the flexibility of your equipment and to make your trenching jobs easier. We offer them to better serve your trench- ing needs. 11142 5-28-08 75649...

MAINTENANCE AND SERVICE LUBRICATION GENERAL INFORMATION Economical and efficient operation of any machine is dependent upon regular and prop- er lubrication of all moving parts with a quality lubricant. Neglect leads to reduced efficiency, heavy draft, wear, breakdown, and needless replacement parts. All parts provided with grease fittings should be lubricated as indicated. If any grease fittings are missing, replace them immediately. Clean all fittings thoroughly before using grease gun. IMPORTANT: Avoid excessive greasing. Dirt collects on exposed grease and greatly increases wear. After greasing, wipe off excessive grease from fittings. LUBRICATION Lubricate grease fittings on cylinder and PTO shaft every (8) eight hours. Grease PTO Drive before putting trencher into operation and at specified intervals thereafter. GREASE INSIDE OF OUTER TELESCOPING TUBE (EVERY 20 HOURS). GREASE EVERY 8 HOURS * When used in winter the outer tube must be greased to prevent it freezing solid!
MAINTENANCE & SERVICE GENERAL INFORMATION Regular maintenance is the key to long equipment life and safe operation. Maintenance requirements have been reduced to an absolute minimum. However, it is very important that these maintenance functions be performed as described below. CAUTION! Always choose level and hard ground to park the tractor on and set the brake so that the tractor cannot roll.
MAINTENANCE & SERVICE DIGGING CHAIN REMOVAL Before removing the digging chain, put the trencher stand in the lowest position to help support the trencher mainframe, and lower the trencher with the 3-point hitch arms. Turn off the prime mover, set the parking break, remove the key and disconnect hydraulic couplers to the trencher before performing any maintenance.
MAINTENANCE & SERVICE HEADSHAFT ASSEMBLY SERVICE Before performing any maintenance, put the trencher stand in the lowest position to help support the trencher mainframe, and lower the trencher with the 3-point hitch arms. Turn off the prime mover, set the parking break, remove the key and disconnect hydraulic couplers to the trencher.
MAINTENANCE & SERVICE Bearing Replacement Follow steps #1 through #4 under “Headshaft Assembly Replacement”. Once the headshaft has been removed from the trencher mainframe, remove the head- shaft housing from the headshaft. Remove the snap rings at each end of the housing to gain access to the bearings and o’rings seals.
MAINTENANCE & SERVICE PTO DRIVE ASSEMBLY The following instructions will assist in replacing the safety shields on your PTO drive assembly. Keep all PTO guards and shields in place at all times. IMPORTANT: Trencher maintenance does not require you to go between the tractor and the trencher with the drive line installed.
MAINTENANCE AND SERVICE CYLINDER SEAL REPLACEMENT The following information is provided to assist you in the event you should need to repair or rebuild a hy- draulic cylinder. When working on hydraulic cylinders, make sure that the work area and tools are clean and free of dirt to prevent contamination of the hydraulic system and damage to the hydraulic cylinders.
