Change a clipper into a shearing machine in minutes! Requires only one screwdriver and just 3 minutes to switch from a clipper head to a shear head.

Interchangeable shear head fits onto same motor as our 4000c clipping machine.

Common uses:
  • Shear heads are used for general flock shearing and for blocking show sheep, shearing llamas and alpacas.
  • On cattle it can body clip, block show cattle or "peel" sale cattle effortlessly.
  • Some folks have also used it to shear guard dogs so that they stay cool in the summer.

Specs

  • Internal roller bearings instead of bushings (less heat, less wear and greater longevity).
  • Sleek, low profile head design (sharp visual look that catches your eye and impresses observers).
  • Suspended fork system (reduces risk of stripping the gear drive or breaking comb teeth).
  • No cutter retainer or retaining spring (both caused hassles and broke too readily).
  • Improved tensioning concept (spring clip is more effective at retaining tension than cupped washers).
  • Tension column far superior in design, less small/individual parts to wear out.
  • No more black plastic sides (these were prone to falling off and frustrating users).


Tips

Tensioning Shear Heads—Why the correct tension is so critical!

To get the tension right:
  1. Tighten the tension knob, until resistance is felt, to force the cutter against the comb. Tighten an additional 1/2 turn.
  2. Apply shearing oil to the comb and cutter.
  3. Turn on the machine. Tweak tension according to comb/cutter heat/cutting ability. To find the sweet spot, adjust tension cautiously while operating.
Too little tension:
  1. Wool gets under the cutter, which prevents cutting. Remove the cutter, clean out the wool, replace the cutter, then reset the tension.
  2. The cutter may fly off, allowing forks to drop between the comb’s teeth—which strips the drive gear.
Too much tension:
  1. Causes excessive friction, dulling the cutting edges quickly.
  2. Heat builds on both the comb/cutter and shearing head.


Installation

See Instructions/Diagrams for fitting and setup.


Precautions

Failure to oil as often as recommended may lead to excess heat and premature wear and tear.

Warning: Unlike some other clipper motors, this motor will neither slow down nor sound different when oil is needed. But failure to oil will quickly cause damage to the blades and drive head. So you MUST apply oil by time instead of sound.

Apply a small amount of oil every 3 minutes to the tips of the teeth and each side of the blade by dipping them into a dish of oil or pouring oil directly onto the teeth with a small oil container and every 10 minutes drip oil into the small hole behind the tension knob assembly. Excessive wear can occur if not oiled properly!

Shear Head Only
★ ★ ★ ★ ★
September 11, 2022

Donna L from California

This was handy to be able to buy just the part we needed. Once we put it on the old Premier 1 shearer, it worked great. We use about 3 or 4 machines while we’re shearing because they do get hot, so it’s nice to be able to rotate them.

It worked out great. We have the shears and the motor was working fine. The shear head was worn out. The staff at Premier assisted me to just purchase the head. Saved me $200. Shears work great! Got the llamas done for the summer!

About Conductivity

Conductivity measures the amount of electrical current a material can carry. The opposite measure is known as resistance.

Tinned Copper Superconductor

Many of Premier’s electric net fences feature a green and white superconductor that has both stainless steel and tinned copper filaments for optimal conductivity.

These “premium” nets are 10 times more conductive (38 ohms per 1000') than “basic” nets offered by our competitors. This enables the electric pulse to travel much farther and be less affected by weed contact.

Customers who are unhappy with netting are often those who’ve chosen nets from China or their farmstore equivalents.

Types of Line Posts

Line posts are built into the net. Three options are available.*

Line Posts Compared
  1. Single Spike (SS)
    The best choice, unless your soils are always soft or very hard.
  2. Double Spike (DS)
    Posts allow you to push in the spikes with your foot. When soil is hard or rocky, double spikes are more difficult to install and remove.
  3. Drivable Posts (DP)
    Allows use of a mallet or dead blow hammer for installing posts in dry, hard or rocky soil. Features a “spike stop” for extra support and internal fiberglass ribs for added strength.

Tip: To insert a line post into frozen or hard soil, use a power tool to drill pilot holes.

* Not all fences have all line post options.

About Positive/Negative (Pos/Neg) Nets

Is your area dry?

Conventional electrified fence systems rely on soil moisture to be effective. However, not all areas have the required moisture.

Dry soil increases resistance—a weaker, less effective pulse occurs that does not deter animals.

To overcome this, Pos/Neg nets* are wired to allow the use of every other horizontal strand as an extension of the ground terminal. Because half the strands are connected to the ground terminal or ground rod, reliance on soil moisture is reduced. A PowerLink must be purchased separately to make the secondary ground connection.

How it works…

In order to receive a shock, the animal must touch both a positive (hot) and negative (grounded) strand at the same time. This will deliver more pain to the animal than an all hot net (Pos/Pos) because moisture in the soil is not required to complete the circuit.

Pos/Neg fences can be converted to Pos/Pos in moist conditions. Remember, all fences must be kept free of vegetation.

* Not all fences have Pos/Neg options.

Line Post Spacing

“Plus” nets—6'8" spacings between built-in line posts*

Line Post Spacing

Standard nets—10' or 12' spacings between built-in line posts*

* Spacings are approximate.
Distance between built-in line posts may vary by product.

Essential Energizer Advice

  • Buy a larger energizer than necessary. When the fence pleases, most folks will buy more fence—and need additional output.
  • Use a low-impedance intermittent pulse energizer.
  • Use a fence tester to check the voltage often.
  • Use enough ground rod(s)—included with our energizer kits.
  • Don’t allow your lead acid battery to discharge below 40%.
  • Use insulated wire that is designed for electric fences.
  • Always connect the fence to an energizer, not an outlet.
  • Visit this link for answers to other common energizer questions.

Two Basic Types

  1. All-in-one Solar
    • Solar units are very portable.
    • Because they need a battery, these units are more costly to purchase and operate than plug-in units.
    • Batteries are less effective in cold temperatures (deplete faster).
    • Most farmstore solar units are too weak, in joules of output, to properly energize netting. That’s why we designed our own.
  2. Plug-in & Battery
    • Least cost to purchase and operate per joule of output.
    • Best for fences exposed to heavy vegetation.
    • Cold temperatures do not affect performance.
    • Recommended for whole-farm systems, but can be complex to install. Higher output requires more ground rods, underground cables, multiple output terminals, etc.

Premier 1 Supplies

Dan Morrical joined the Iowa State University staff in 1984 as Extension Sheep Specialist after completing his doctorate degree at New Mexico State University. He held the rank of Full Professor as of July 1, 1995 and retired from full-time teaching in 2017.

While at Iowa State University, Dr. Dan Morrical was responsible for educational programs in all areas of sheep production, ranging from nutrition, genetics, marketing and management. Research areas focused on applied projects in the areas of nutrition, forage utilization, genetics, out-of-season breeding and lamb survival.

Dr. Morrical has been heavily involved in providing educational resources to the sheep industry. He has authored over 30 extension fact sheets, ration balancing software programs, grazing videos and co-authored the nutrition chapter of the SID Handbook with Dr. Margaret Benson from Washington State University.

Dr. Morrical now serves as Premier’s on-staff small ruminant nutritionist and sheep production advisor. Most recently, he’s introduced a line of “GOLD FORMULA” mineral premixes under The Shepherd’s Choice® brand, aimed to maximize hoof health and immunity.

Braided vs. Twisted

Braiding instead of twisting the horizontals increases the frequency of metal filaments on the outside of the strand.

Braided vs. Twisted Electric Net Fences

What’s the benefit?

  1. More metal is exposed on the outside of the strand. This enables improved animal to conductor contact. The electric pulse is better able to travel from the fence and into the animal, resulting in a memorable shock.
  2. A tighter, braided weave results in fewer snags when carried or pulled through pastures, reducing frustration.
