Section 2: Operating

The cutting angle is defined as the angle the cutter bar is to the tractor axle during operation. For example, cutter bar angle would be down if cutting a declined surface from a level surface and up if cutting and inclined surface. Do not exceed a maximum of 35° up or down. Damage to cutter gears, belt guard and drive belt may occur.

!DANGER

Do not use machine in rocky or stony conditions.

Extra care and precaution should be taken in rough or debris-ridden fields. The following adjustments should be made to the mower in these conditions to minimize possibility of foreign objects being deflected by the cutting blades.

1.Lengthen top 3-point center linkage to tilt angle of cutter bar and raise height of cutter knives.

2.Reduce forward speed.

3.Check cutting blades to make sure they pivot after hitting an obstruction.

IMPORTANT: If an obstruction is hit, disengage PTO, idle engine, shut off tractor, remove ignition key and wait for all moving parts to come to a complete stop. Inspect entire mower and repair any damage before resuming operation.

!CAUTION

Do not disengage PTO when engine is at full PTO rpm except in emergency situations such as when hitting an obstruction. When possible, always idle engine before disengaging PTO.

IMPORTANT: To avoid personal injury, pick up all rocks and other debris before mowing. Never assume an area is clear, so enter a new area carefully. Cut material higher the first time to allow mower to clear unseen objects.

Safety Break-Away

The break-away latch allows cutter bar to swing back if an obstruction is hit. If latch releases, stop tractor immediately, idle engine and disengage PTO.

To reset cutter bar, back mower slowly and carefully until break-away latch repositions. The factory setting of latch is adapted to most working conditions.

Check cutter bar for any damage before resuming operation.

If cutter bar continues to break away after resetting, spring assembly pressure can be increased. In all cases the length must not be less than 3 3/4” to 3 7/8” or safety disengagement cannot function.

The stack of spring washers should be compressed to 3 3/4” to 3 7/8”. See figure 2-8

Operating Instructions

By now you should have thoroughly read your Disc Mower Operator’s Manual, properly attached your Land Pride Disc Mower to your tractor, and reviewed Operating Check list. If you have not yet completed all of these functions, please do so now.

Now that you’re properly briefed and your Disc Mower is ready, it’s time to transport to the field.

For transport purposes, your Disc Mower should be securely locked with the cutter bar in the upright or vertical position. Make sure the support leg is in the high position. A “Slow Moving Vehicle” sign should be in place and visible from the rear if you are using a public road or right-of-way. Select a safe speed and transport to your cutting site in such manner that faster moving vehicles can pass you safely.

Once you have safely arrived at your field, position the tractor on level ground. Make sure that no one is within 20 ft of the mower and lower the 3-point hitch to a point where the inboard end of the cutter bar is approximately 12" off of the ground. Retract your lift cylinder and pull on the latch cord to release the transport or road-latch mechanism. Using your lift cylinder control lever, slowly lower the cutter bar until the outer end touches the ground. Adjust the 3-point hitch to “working position” where the hitch level stop pin aligns with run indicator arrow as shown in Figure 2-2 on page 13. Lock the 3- point hitch control lever in place. Lock the hydraulic lever of tractor in float position. Your Disc Mower is now in working position.

Controlling or setting your cutting height is accomplished by adjusting the “top link” on your 3-point hitch.
