Lawn mowers / Who's got one of the new Hayter Harrier's
« on: June 14, 2019, 04:55:47 PM »
Who's got one of the new hayter Harrier 48 Model 475A, 48 Pro 479A, Or 56: 575A, 56 Pro 579A? Just wondering what you think of them compared to the older models.  These are the ones with the BBC blade clutch.

Think the contractor will love them as they are so bloody fast compared to the older models.  In fact if I didn't know better I'd say they have made them a tad too fast for most users. That said they do already supply a kit to sow them down, but I haven't seen or fitted one yet.

Cordless Power Tools / A good year for cordless mowers
« on: May 04, 2019, 05:55:55 PM »
Quite a few cordless mowers being sold this year, they seem to be catching on. 

My favourite is still the EGO range though.  Like the idea of having separate motors for the drive and blade, and all controlled by simple switches.

Lawn mowers / Briggs Instart engines. @BriggsStratton
« on: May 04, 2019, 09:48:39 AM »
Had four machines in a week all with Briggs Instart engines, and all but one with the same, known electric start fault. 

The fourth one having a faulty decompressor and that causing the battery to have a fit, and shut down. This was on a brand new Harrier 56 which was two days old, and used for the first time.

This system has been out for a while, but it's strange we have all these at the same time, I've a feeling there might be more to come.

Read so many posts about engine porting, and I realise when this is done properly you will gain extra power / speed from your chainsaw.

Then you read about the guys who opened up their muffler / exhaust on their brand new chainsaw and it runs so much better.  This begs me to ask the question.  Taking into account that a blocked muffler will defo have a negative affect.

Does opening up the exhaust really give you extra power?  How much of this is placebo effect on the user, I mean the extra noise possibly making it sound more powerful, and actually not having any affect on the performance at all, apart from making it possibly worse.

In my opinion the stock muffler should be optimised from the factory for max performance and longevity of the saw, not to mention noise levels, and emissions = (CAT versions).

What's your take on all this?

Lawn mowers / Top Tips

When replacing the gearbox on your lawnmower, always replace the clutch cable at the same time. Otherwise the life of your new gearbox could be shortened considerably.

Make this part of your routine.

Lawn mowers / Weibang 48V
« on: November 29, 2018, 11:16:16 PM »
Changed the gearbox on a Weibang 48V today. Fairly easy job apart from getting hold of the correct clutch cable to go with it.  UK distributor supplied the gearbox and cable together but the cable is completely different from the original, and it doesn't fit. 

It reminded me as to why I don't like repairing Weibang machines.  :(

Blowers and Vacuum Shredders / Stihl Blowers eating diaphragms
« on: November 24, 2018, 06:28:28 PM »
Seems the Stihl BG 86C-E blowers and SH 86C-E vacuum shredders like eating pump diaphragms, had five of them over the last few days, with exactly the same problem.  Think they need to rethink the material these are made of.

This problem is guaranteed to wreck the crappy recoil starter on thee machines. Trust me.  ;)

Lawn mowers / Variable speed verses fixed speed
« on: August 19, 2018, 09:41:56 AM »
Think the manufacturers should rethink the whole variable speed idea on their mowers.  The new systems that the likes of Hayter, Viking (Stihl), Cobra, and many others are now using is a complete mare. A load of unnecessary moving components that ware out even when a majority of people only use it in one speed.

In my opinion for reliability they should supply a speed kit.  A larger or smaller front pully with matching belt.  Once fitted will be a much more reliable system.

General Discussion / Warranty when using Alkylate based fuel mixes
« on: July 21, 2018, 07:01:04 PM »
Noticed Cobragarden has decided to throw warranty out if using Alkylate based fuel mixes with at least one of their chainsaws, there might be more than one model.

Just wondered if anyone else has seen other manufacturers doing the same.  I'll quote the Cobra Technical Bulletin below:

Cobra Technical Bulletin:

Factory tests have shown the Cobra CS620 Chainsaw's piston and cylinder are overheating and becoming damaged when used with Alkylate based fuel mixes (e.g. Aspen). This can cause the engine to fail.

This model should only be run using a 40:1 petrol/oil mixture.

You will invalidate your warranty if you use Alkylate based fuel mix with the Cobra CS620-20 petrol chainsaw.

Lawn mowers / Belt guards
« on: June 23, 2018, 12:53:59 PM »
Have you ever seen a belt guard / cover on any lawnmower that doesn't fill up with grass and cause problems.  You'd think in this day and age one of the manufacturers would be able to crack it.

Lawn mowers / Ariens Razor Belt
« on: June 23, 2018, 12:31:10 PM »
Had two of these Ariens Razor pedestrian mowers in over the last week, both with the drive belt fallen off the crankshaft pulley.  No other signs of damage.  I figure these were not set up properly from day one. (Cable adjustment) and the belts were running so loose when you released the drive lever they flipped off.   

Will keep an eye out now the belts are refitted, and adjusted, and see if cures it.

As a side note:  I'm guessing the removable portion of the belt guard, the bit around the front pulley could be slightly closer to the pulley, or run slightly more parallel to the pulley to prevent this happening, as long as there's enough room for the belt to break away for clutching.  Belt on both machines ended up on top of the crankshaft pulley.
