My B & D electric hedge trimmer blades are frozen

I had a similar problem, with a headg trimmer, it was working fine, just stoped. It did not get stuck, or caught up in anything, on dismantiling, as you say, motor running, no drive.
It was get a new one, or bust, so I put a small tack of weld on gear/drive and reduced fuse rating to 8 amps, (from 13 A) incase I got it jamed, its fine now.
I never could figure how the drive got from a gear to the oscillating leaver, must have been a clutch somwhere inside, anyway, weld sorted that out....

This sounds similar to a problem I have with my Bosch AHS 60 24s. The blades are moving but not independantly and therefore not in a cutting action. I took it apart and the bottom blade has slipped off the drive wheel. I put it all back as it should be but as soon as I used it again, the same thing happened. I'm not sure why this is happening, it may be that the motor end of the bottom blade has become slightly bent, so I will be trying to straighten at the weekend. The cost of replacement blades is prohibitive and time for a new hedge trimmer. Has anyone else had this problem and a different solution.

How to Sharpen a Black and Decker Hedge Hog Maintaining the sharpness of electric timmers can made landscape trimming easier with beautiful results.

Electric hedge trimmers make trimming hedges and bushes easier and quicker than using manual hand-powered trimmers. Electric trimmers, the most popular type in the U.S., cost less and require less maintenance than gasoline-powered models. Electric trimmers are used most often by homeowners with the Black and Decker Hedge Hog series being very popular. While they are not premium products, electric trimmers like the Black and Decker Hedge Hog trimmer can keep trimming reliably for years with proper maintenance, including sharpening the blade's teeth.
Difficulty: Moderately Easy Instructions Things You'll Need

• Work table
• Two medium size clamps
• Dremel tool or similar hand-held multi-purpose tool
• Grinding wheel attachment for hand-held tool.
• Dremel 971 (or similar) aluminum oxide grinding sharpening stone with a tip small enough to cover the flat facet of a Hedge Hog blade tooth

1. • 1 Unplug the electric trimmer before trying to sharpen the teeth.
     
   • 2 Clamp the electric trimmer to the work table using two clamps if necessary so the Hedge Hog is firmly held down with the blade teeth accessible over the edge of the work table.
     
   • 3 Insert and secure grinding tip in hand-held multi-purpose tool.
     
   • 4 Maneuver the grinding tip so it is perpendicular to the facet of the Hedge Hog tooth.
     
   • 5 Sharpen teeth in one direction, being careful to try and maintain the same cutting edge angle on the sharpened tooth of no less than 35 degrees.
     
   • 6 Make same number of grinding passes/grind the same length of time a few seconds on each tooth.
     

Tips & Warnings

• This task should take about 15 minutes.
  
• Keep a light touch; too much force can break the grinding surface.
  
• For best results, insert the sharpening bit slightly less than all the way into the tool.

A hedge trimmer is a type of agricultural or garden tool. And as the name suggests, it is used to trim hedges. There are mainly two types of hedge trimmers - manual and electrical. Amongst these there are some below mentioned variations.

Stand Alone: A stand alone hedge trimmer could be either power driven or manual. The power driven stand alone hedge trimmer uses gasoline or electricity to operate. However, the manual or hedge trimmer driven by human force is best when you consider environmental factors. They are cheaper and easy to operate. Generally gas powered hedge trimmers or electrically powered hedge trimmers are equipped with safety devices. The mechanism is such that they operate only when the operator has both his hands on the handles.

Tractor Mounted: This type of a hedge trimmer is more suitable for pruning of plants and crops. Tractor mounted hedge trimmers either have a movable arm or they do not have a movable arm. The ones without movable arms depend only on rotating blades on a couple of central pivots placed on the tractor's side. Now, these hedge trimmers are best for growing grapes, more specifically for making wine. Small tractors driving between the grape vines are mounted with these type of hedge trimmers, without a movable arm.

Well, this was about hedge trimmers in general. Now lets get down to business. Here's a low down on a few best hedge trimmers. The following is an overview of electrical hedge trimmers comparison.

Hedge Trimmer Reviews

Stihl Hedge Trimmer HS81T: Well, this one is surely up for grabs. Stihl HS81T is a great option for keeping your hedges in a perfect shape. Stihl HS81T is lightweight with balanced design and low vibration levels. It has 24 inch or 30 inch double sided blade length. It's also equipped with rear swivel handle for enhanced comfort at different speeds. The engine power is 0.7 kW and this hedge trimmer weighs between 5.2 kg and 5.4 kg, depending on the blade size. It is good especially for shaping and sculpting your hedge. It does not start on the first pull sometimes, still Stihl is a good option for hedge trimming.

Black & Decker NHT518: Now you would perhaps love this, if you do not want the whole baggage of fuel and electric wires and so on. It is cordless and runs on a battery and 22 inch blades that give a smooth and level cut. It does a neat job of branches less than 1/2 inch thick and you get optional extra battery packs. However, it gets a thumbs down from users with regards to poor battery life. On the other hand the users like the cordless design. Again, they say that it is not as powerful as corded trimmers. Nevertheless, it is lightweight and makes minimum noise. So you can go for it.

Echo HC-150 Petrol Commercial Grade Hedge Trimmer: Well, hopefully most of the users would echo my statement that, Echo is a very efficient hedge trimmer. This is a high performing, commercial grade hedge trimmer powered by petrol. It is a smooth and **** free hedge trimmer and is great for pruning and trimming. Durability is apparently the forte of this Echo hedge trimmer. Superb double reciprocating blades cut on their return and forward strokes, which give a smooth, uniform finish to your hedges. Not a bad choice either!

Makita UH6350 Electric Hedge Trimmer: This is a well designed tool with a great cutting action, according to a magazine on mechanical products. It is light weight and can deal very well with branches upto ½ inch of diameter. Although one of the disadvantage is that you have to bear with a cord and has a single blade operation. A fairly good option if you are thinking of buying a hedge trimmer.

Well, there you go, this was a small list of best hedge trimmers. I hope the hedge trimmers comparison was useful for you.

Take your pick according to your requirements and any hedge trimmer is good so far as it helps you keep your plants in good shape! What say!

Had the same problem: when I turn on the trimmer, the motor would hum but the blades won't move.
What I did:
1. Sprayed a ton of wd40 between the blades
2. Took a screwdriver and kinda wedged it between the blades to get them unstuck. Also removed some guck between the blades.
And it worked!

Your blades are stuck together.

I have a Troy-Bilt gas powered hedge trimmer. My blades would not move. After tearing it apart, I found that there were some spacers under the 5 or 6 screws along the blades. These spacers are steel and designed so that you don't overtighten the screws. However, around those steel spacers, there is a teflon type material that makes the oval shape of the slot. That teflon had fallen apart and lodged so that the blades would not move. I removed the teflon and put the spacers back in and it now works fine. There is a little play between the spacer and the edge of the slot and it will probably eventually wear out but at least I got a few more cuttings off of it.

I use a dremel with a sharpening stone, if u don't have one you can also use a power drill with a small sanding disk (1 inch) and course sand paper (30 or 40 grit). or you can use a bastard file. its too tight to use any kind of angle guide so just take your time and do it by eye. it shouldn't take much to get them sharp enough to do the job, over-sharpening is unnecessary and dangerous, and will make the blades dull faster. sharpen all the free blades, top and bottom, then start the trimmers to advance the blades to free up the sides you couldn't get. i use a light penetrating oil to clean the blades first, then lithium grease spray to lubricate.
