Chapter 4 Operation and Maintenance DANGER Never allow anyone to ride on the 7450 VT Plus at any time. Allowing a person to ride on the machine can inflict serious personal injury or death to that person. DANGER Disc blades are extremely sharp. Exercise extreme care when working on or near disc blades. Do not allow discs to roll over or fall onto any bodily part. Do not allow wrenches to slip when working near disc blades. Never push wrenches toward disc blades.
OPERATION AND MAINTENANCE Tractor Preparation VT Plus Preparation The Landoll 7450 VT Plus is designed to be pulled by tractor equipped with a double lip or clevis type hitch CAT IV or V. If your tractor is not equipped as such, you need to purchase the hitch from your local tractor dealer. Before attaching the VT Plus, prepare the tractor as follows: 1. Inflate the rear tractor tires equally and add ballast according to the tractor operator’s manual. 2. Lock the tractor drawbar in the center position.
OPERATION AND MAINTENANCE Attaching to the Tractor 1. Align the tractor drawbar with the machine. Raise or lower the disc ring hitch, as needed, using the swivel jack. Attach the unit with proper size hitch pin. 2. Always place the swivel jack on the interior mount before setting the machine in motion. 3. Clean all hydraulic couplings and attach to the tractor. Hydraulic Lift System The VT Plus is equipped with a rephasing hydraulic lift system to raise and lower the unit in the field.
OPERATION AND MAINTENANCE 2. The hydraulic system is not filled with oil and should be purged of air before transporting and field operations. Carefully hitch the VT Plus to the tractor and connect the hydraulic lift hoses. Check to make sure the tractor hydraulic reservoir is full of the manufacturer’s recommended oil. Slowly raise the machine, and continue to hold the hydraulic lever until all lift cylinders are fully extended.
OPERATION AND MAINTENANCE Hydraulic Fold System 1. The VT Plus is equipped with a hydraulic fold system to raise and lower the wing frames for narrow transport. 2. Be sure the system is fully charged with hydraulic oil before attempting to fold/unfold the unit. Air in the system can allow uncontrolled dropping of the wing frames causing serious personal injury or machine damage.
OPERATION AND MAINTENANCE CENTER LIFT TRANSPORT LOCK DISENGAGED Folding the 7450 VT Plus WING LOCK PIN 1. Fully raise machine. 2. Begin folding the machine. Transport locks will engage on the center lift as the outer wings are folding, fully fold all inner and outer wings (See Figures 4-6 and 4-7). 3. Take note that both center lift transport locks are engaged.
OPERATION AND MAINTENANCE General Operation Field Operation 1. The horsepower requirements are typically 8-10 horsepower per foot of cut. This will vary widely due to speed, depth, moisture, residue and types of soils. Local dealers can help in making recommendations for your areas. 1. Raise the unit to take the weight off of the transport locks. 2. Operating speed is typically 6 - 9 mph. Excessive speed can cause the unit to bounce, uneven depth, and create a ridge on the outside edges.
OPERATION AND MAINTENANCE Leveling (Side to Side) 1. An adjustable radius rod connects the center frame lifts together to keep them operating in unison. The radius rod does not level the center frame lift. The radius rod length is determined initially by fully retracting the lift cylinders and adjusting the radius rod until it is loose and tightening the jam nuts. 2. To level the center frame: a. Verify that all of the tires are properly inflated. b.
OPERATION AND MAINTENANCE 3. After adjusting the cylinder rod or rods, the radius rod needs to be adjusted back to a neutral position. This is accomplished by fully retracting the lift cylinders and adjusting the radius rod until there is no load on it, and then tightening the jam nuts on each end. NOTE MEASURE Center frame cylinders may have 1/8” rod exposed when fully retracted due to the rephasing system. 4. Leveling the VT Plus side-to-side involves leveling the wing frame to the center frame.
OPERATION AND MAINTENANCE Leveling (Front-to-Rear) 1. The leveling feature on the VT Plus is used to keep the machine level when raising the unit from a working position to a transport position. The leveling feature is also used to level the unit from front-to-rear to perform a level discing operation in the field. 2. The unit should be level from front to rear and the soil behind the disc should be level without furrows or ridges.
OPERATION AND MAINTENANCE Hitch Adjustment 1. It is important for the VT Plus to maintain a proper draft line with the tractor to do a level job of discing. The draft line will vary depending on soil conditions and tractor drawbar height. The VT Plus is equipped with an adjustable hitch to help insure a proper draft line with the tractor. 2. Generally tractor drawbars greater than 17” tall will require the hitch to be in the upper position. 17” drawbars and below should be in the lower position.
OPERATION AND MAINTENANCE Scraper Adjustment The VT Plus is equipped with rigid scrapers at regular spools with dual scrapers at the disc bearings. 1. Rigid scrapers should be set initially as close to the disc blade as possible without rubbing (approximately 1/8”) (See Figure 4-15.) A slotted hole at the top of each scraper is provided for individual adjustment. Adjustments may be made for entire gangs, by loosening the u-bolts around the angle-iron scraper bars and sliding the whole bar.
OPERATION AND MAINTENANCE Front Gauge Wheels IMPORTANT 1. The VT Plus is equipped with castering gauge wheels at the outer front corners of each wing. These gauge wheels are used to limit depth of the wings, and prevent gouging and buckling of wing frames. 2. Gauge wheels are not intended to carry the wing, but prevent excessive depth. Adjust the wheels to carry some weight, but not enough to hold the wing from reaching operating depth set with the main lift hydraulics.
OPERATION AND MAINTENANCE Disc Blades 1. The 7450 VT Plus is equipped with 22" -6 ga. (.197"), 22" -4 ga. (.256), or 22" -4 ga. (.256 )rollable low concavity disc blades on both front and rear. The use of other concavity blades can give unpredictable results and is not recommended. 2. Sharpening – In some cases there is a desire to sharpen disc blades for improved cutting. There are several people who roll-sharpen disc blades. Most disc blades used today are made of chrome-boron steel.
OPERATION AND MAINTENANCE Depth Stop Adjustment (Manual) DEPTH STOP TUBE The operating depth of the VT Plus is controlled by a single-point depth stop. The stop is located at the center front of the machine. DEPTH STOP GAUGE 1. Adjust the depth stop by turning the handle out (counter-clockwise) to increase operating depth (See Figure 4-18.) Turn the handle in (clockwise) to decrease operating depth. One turn will equal approximately 1/8” adjustment in depth. 2.

OPERATION AND MAINTENANCE 1. Lower machine until tires are off the ground, the depth stop may have to be adjusted to allow cylinders to retract far enough. 2. Remove tires. 3. Remove hub cap and catch lubricant. 4. Straighten tab of star washer, remove outer spindle nut, star washer, spindle locking washer, inner spindle nut and bearing. Remove hub from spindle. 5. Using an appropriate driver, remove inner bearing cone and seal. 6. Clean and inspect the bearings and hub cavity.
OPERATION AND MAINTENANCE Hydraulic Maintenance Transport 1. Check the tractor hydraulic fluid level per tractor owner's manual and after any leakage. Check fluid level with the cylinders in the retracted position. 1. Check and follow all federal, state, and local requirements before transporting the VT Plus. 2. If a cylinder or valve leaks, before disassembling the part, contact Landoll service at 785-562-4721 for further direction.
OPERATION AND MAINTENANCE 6. A safety chain is provided with the implement to insure safe transport. a. The safety chain should have a tensile strength equal to or greater than the gross weight of the implement. The chain is attached to the lower hitch clevis hole with two flat washers between the clamp plates to assure a tight connection. Always use a 1” diameter Grade 8 bolt for this connection. b. Attach the safety chain to the tractor drawbar (See Figure 4-21.
