Maintenance

Proper servicing and adjustment is the key to the long life of any implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.

After using your Rotary Cutter for several hours, check all bolts to be sure they are tight.

Replace any worn, damaged or illegible safety labels by obtaining new labels from your Land Pride Dealer.

Cutter Blade Maintenance

!DANGER

Always disconnect hydraulic hoses from the Skid Steer before servicing underside of deck. The motor can be engaged if Skid Steer is started resulting in possible damage to the cutter, bodily injury and/or death.

!WARNING

Always secure the cutter deck in the up position with solid supports before servicing the underside. Never work under equipment supported by hydraulics. Hydraulics can drop equipment if controls are actuated or if hydraulic lines burst. Either situation can drop the cutter instantly even when power to the hydraulics is shut off.

IMPORTANT: Replacement blades should be ordered in pairs. Order only genuine Land Pride blades. Other blades may not meet specifications.

Always inspect cutting blades before each use. Make certain they are properly installed and are in good working condition. Replace any blade that is damaged, worn, bent, or excessively nicked. Small nicks can be ground out when sharpening.

Remove cutting blades and sharpen or replace as follows:

1.Align blade bolt with access hole in deck.

2.Place skid steer in park and/or set brakes, shut engine off and remove ignition key.

3.Always disconnect hydraulics from Skid Steer and secure cutter deck in the up position with solid supports before servicing underside of cutter.

4.See Figure 5-1. Unscrew locknut (#6) to remove cutting blade (#3). Blade bolt (#1) is keyed and will not turn freely.

5.Both blades should be sharpened at the same angle as the original cutting edge and must be replaced or re-ground at the same time to maintain proper balance in the cutting unit. The following precautions should be taken when sharpening the blades:

a.Do not remove more material than necessary.

b.Do not heat and pound out a cutting edge.

c.Do not grind blades to a razor edge. Leave a blunt cutting edge approximately 1/16” thick.

d.Always grind the cutting edge so that the end of the blade remains square to the cutting edge and not rounded.

e.Do not sharpen the back side of the blade.

f.Both blades should weigh the same after sharpening with not more than 1 1/2 oz. difference. Unbalanced blades will cause excessive vibration which can damage gearbox bearings and create structural cracks.

6.Carefully check cutting edges of blades in relation to blade carrier rotation to ensure correct blade placement. Cutter blades must be installed with cutting edge leading in rotation and airfoil (lift) must be oriented towards the top of the deck.

Refer to Figure 5-1:

IMPORTANT: Shim (#2) below may or may not be required. If blade deflection is less than 3/4" without a shim, then the shim is not used. However, a shim is required if blade deflection is greater than 3/4".

IMPORTANT: Locknuts can loose their ability to lock properly once removed. Therefore, always use a used blade nut or plain nut in steps 7 & 8 below and then replace used nut with new locknut in step 9.

7.Start by assembling blades without shim (#2). Insert blade bolt (#1) through blade (#3), dish pan (#4) and flat washer (#5). Temporarily secure blade with a used 1 1/8"-12 nut. Draw nut up snug. Do not tighten.

8.Check blade deflection. If deflection is greater than 3/4", remove blade bolt and reassemble as before except include shim (#2) when reassembling. Select shim thickness based on deflection. The greater the deflection, the thicker the shim.

9.Once blade deflection is correct,replace used nut with new locknut (#6) and torque to 450 ft. lbs.

10.If replacing dishpan (#4), nut on gearbox output shaft should be torqued to 450 ft-lbs. minimum and secured with a cotter pin installed through the nut and bolt and both legs bent opposite directions around nut.

Built with high-quality materials, these tillers ensure durability and longevity, allowing them to withstand the rigors of demanding soil conditions. The two models differ primarily in width, with the SC2660 featuring a 60-inch working width, while the SC2672 offers a slightly wider 72-inch option, catering to various land preparation needs.

Both tillers are equipped with heavy-duty tines made from hardened steel, providing excellent soil penetration and thorough tilling action. The tines are designed to break up compacted soil effectively, promoting better aeration and root growth for crops. The adjustable tilling depth feature allows operators to customize the tilling process to meet specific agricultural requirements, ensuring optimal soil health and structure.

The SC2660 and SC2672 incorporate a chain drive system that delivers reliable power from the tractor to the tiller. This efficient drive mechanism reduces wear and enhances the tillers' overall performance, ensuring a smooth operation even under challenging conditions. The adjustable side skids provide further flexibility, allowing users to control the width of the tilling area, which is particularly beneficial for row cropping applications.

Another important aspect of these tillers is their ease of use. The quick-hitch compatibility allows for fast attachment and detachment, saving valuable time in the field.
