INTRODUCTION Product Description The new VENTRAC Model HQ680 “Tough-Cut” rotary mower features an enclosed deck designed for field and brush mowing. The broad, belted, high intake front creates an “attack” on tall grasses and brush before it is leveled. The straight front deck design provides structural strength and a uniform performance in tall vegetation. Two cast-iron gauge wheels with 5/8th inch rubber coating, roller bearings and grease zerks help to gauge the mowing depth and reduce scalping.

SAFETY HQ680 Safety Procedures Before making any repairs or adjustments, lower attachment to the ground, set parking brake, shut the engine off, and remove the key. Read and understand the operator’s manual before operating this equipment. • Do not mow in areas that contain stones, sticks or other foreign objects that may be thrown from the mower. • Rotating Blades Are Dangerous • Stop the machine if a person enters the mowing area.
OPERATION Setup Instructions for the HQ680 Tough Cut Mower Jack Stand Installation: To install the jack stand into the mounting tube as shown below, raise the back of the mower far enough to insert the stand in the tube. This can be accomplished be setting the mower crosswise on the crate or using a lifting device. Remember, whatever method is used keep safety in mind and use common safety procedures such as using stands, blocking, or a restraining device.
OPERATION OPERATING INSTRUCTIONS Attaching: 1. Drive the tractor slowly forward into the mating arms on the mower. Align the hitch arms to complete the engagement. 2. Once completely engaged, close the front hitch latch. 3. Stop the tractor engine. 4. Place attachment belt over the outside groove of the PTO drive pulley on the tractor. 5. Engage the PTO spring tension lever. 6. Lift up jack stand. 7.
OPERATION Operating Techniques and Tips: With a little practice, operation of the mower will become very easy and simple. Always keep SAFETY as the First Priority. Remember to keep the size of the task appropriate to the size of the equipment. Always shut off engine and remove key to clean or make adjustments on the mower. Travel to and from the area to be mowed should be done with the mower raised in transport position by the tractor hydraulics.
OPERATION Operating Techniques and Tips (cont.) Wet or lush grass has some tendency to build up under the deck. Clean deck periodically and particularly if and when mowing performance seems to be reduced. Cleaning Procedure 1. Raise the deck all the way up. 2. Turn the tractor off. 3. Remove the 2 ball pins from on top of the Hitch Arms. 4. Move the jack stand to the middle notch. 5. Lift the front of the deck up, placing the ball pins in the front locking holes. Blades should be kept in good condition.
OPERATION Use of Duals for Mowing On level to modest inclines, single tires will suffice. Single tires should be inflated to 7 psi and outside dual tires to 3-4 psi. Lower inflation pressure reduces grass and soil compaction. On significant inclines, even if only a small portion of the total mowing to be done, the tractor should be equipped with dual tires for increased stability. If you are uncertain about the need for duals, you should favor using them for your own SAFETY.
MAINTENANCE Lubrication Grease zerks are located as shown below. Apply 2-3 pumps of grease per spindle approximately every 50 hours of operation. All other bearings—one pump max! Do not over grease. In very dirty, sandy, or wet conditions, more frequent greasing may be advisable.
MAINTENANCE Removal and Reinstallation of Mower Blades for Sharpening or Replacement: Wear Heavy Gloves. 1. With the deck fully raised, place the tractor on a level surface. Set the parking brake and remove the key from the tractor. 2. Remove the latch pins, and lift the deck to the near vertical position. Reinstall the latch pins. Note: Interference of cover shield can be eliminated by removing the hinge “hair pin” and then the cover shield. 3.
MAINTENANCE Belt Replacement: If belts become excessively worn or cracked, install a new belt. This is done most easily with the deck removed from the tractor. Main Deck Belt Replacement: 1. Remove old belt. Note that one belt loop must surround the left hitch arm. Remove left hitch arm for access. 2. Install the replacement belt as shown in the diagram below. Begin by placing one belt loop around the left hitch arm. Place belt into the idler pulley and then the drive pulley.
