UMK425ULSTUT from Bunnings - RUBBISH

So I picked this up after reading the reviews on how good they were and how much better than two-stroke ones.

First off, it does not start “first pull every time” or second, or third - and if it’s hot, you can forget it. The Honda brochures all say these things start easy - decompression blah blah blah.

I regret buying this overpriced junk. Aside from it not starting any easier than a two-stroke, the power is just not there. It bogs down in longish grass, wet grass, thick grass - man it sucks. Super under-powered with zero umph.

Funnily enough, the issue I had today (dying when trying to bring to half/full throttle) went away if I held it upside down?? Turn it back over (with the trigger still pressed) and it cuts out. You’d imagine it would be the other way around?

I’m going to give this one more day of use (this is day two of extremely annoying underpowered, bogging down, cutting out rubbish) then it’s going back. 4 strokes suck big time so far.

Definitely not worth the overpriced dollars I paid for this PITA machine.

Purchased in at Bunnings Warehouse for $404.

Quality product

I bought one for $468 from Bunnings as my Ryobi was getting old, the plastics had perished and it leaked fuel plus I had a 4 stroke mower so I considered upgrading to a 4 stroke brush cutter.

It comes full assembled in the box, a bit unwieldy in the store (excuse me, sorry, pardon me, yeah its a longer box, sorry etc etc) but makes unboxing and using as simple as it gets. Dont forget to buy the oil, I just used the Honda oil as recommended.

A drawstring bag comes with it in the box. containing the shoulder strap, instructions and handy safety glasses, Nice.

You need to add 80mL of oil, the oil filler is clearly marked as is the warning of No Oil. Then, its add straight petrol its not a two stroke, dont add mixed fuel !!!

It took some pulls of the starter and choke application to get the fuel where it needed to be, then just brooooom..... and burbled away nicely with the choke off.

The difference is remarkable, no harsh two stroke ring, just a steady rumble and zero smoke.

The hardest part wasnt revving it like a 2 stroke. Just add enough trigger to get even revs and apply the cutter head accordingly. Smooth, easy torque that handles quite thick grass easily.

It seems small, but is perfectly capable for the house yard and probably some larger applications.

The thing that struck me the most was the smooth engine, very high quality Honda construction and the ease of use. Excellent buy, even for the higher price, zero regrets.

An absolute failure

I’ve had the same problem I see many others have had. Minimal power. Constant stalling after a minute or two and no improvement after 8 visits for the machine to be repaired. Even pretty much immediately on getting it back cleaned out and with fresh fuel. An absolute failure. It would definitely the worst piece of gear I’ve ever owned. At least now I know it’s not just me. Show details

Low build quality falling apart after 6 hrs

I bought the 25 cc bike handle model. Plus points good harness and balance. Easy start. But low power and the cutter head falls apart constantly about every 30 mins made of floppy cheap plastic. Line cutter fell off after five hours. I am so disappointed Honda used to be a good make. May as well get a Ryobi for 250 now Show details

This 4-stroke Honda has never missed beat in 25 years

Never been at the mower shop. Started every time. Has done some very heavy work. I'm just about to replace it after a quarter of a century.Hope they are still as good as 25 years ago. Show details

I'm Sexy and I mow it

Use the shoulder strap as its heavier than a 2 stroke.. I use it up to an hour or more straight every day. Speed feed line head. DONT overload it with line, it crosses over & breaks inside the head case. It must be stored with petrol cap up. The cap leaks fuel badly. I have two and both the same. Reliability and performance 10/10. I service every ft night. Very important to do that. Dont complain if you don't. It takes 10 minutes and cheap. Oil (100ml.) and carby air filter. easy.
Plastic cowling isnt that strong. Show details

Smoothest trimmer ever owned

Bought this brand new and used for about an hour and already in love. It’s much quieter and smoother than my 2 stroke Husqvarna 525RS, with only less power, but enough for me. Would recommend for domestic use. Show details

Absolute crap

Mine is now out of warranty continues to stall after short periods of use . Just tried to the house yard and a bit extra stopped 9 times have to wait every time for it to cool down. I have take it back to the place of purchase with this fault never comes back fixed has cost me heaps for no result. If I could afford to I would dump it and by another machine definitely no a HONDA. Show details

Hard to fault after 15 years

After going cheap with a ryobi and the fuel lines perished after 2 years decided a honda might be worth the extra $. With the honda only replaced primer after 10 years and still has original fuel line. Easy to service yourself and have replaced air filter and spark plug as needed. Like the fact it uses the same fuel as the mower. If you need full power all the time a 2stroke might be better and lighter. For me the throttle control of the 4stroke for varied conditions is another plus. Most issues people have would be fuel related (stale). Show details

10 year review

I purchased one about 10 years ago. I have never had a problem with it until now and to be honest I couldn't have been happier. It still starts straight away. I haven't been easy on it. If I put it in to be fixed I am sure it would not take long however I am about to upgrade and will be purchasing the same one to replace the old one. I cannot fault the Honda! Show details

What is the difference between the UMK425ULSTUT sold by Bunnings and the UMK425L sold by most others. Is that just a gimmick to avoid matching prices as no one else sells the Bunning model.

Can you put an edger gear head on one of these line trimmers? I have a spare umk425 that I wanted to turn into a dedicated stick edger.

Really would not know. Best ask a dealer. I just lost more hair trying to keep it running while trying to cut grass.

Details

The Honda UMK425 is available in two options, with the difference between the models being in their handle design.

  • UMK425 Loop Handle: Suitable for neatening up garden beds, driveways and brush cutting.
  • UMK425 Bike Handle: Design allows you to get a solid grip while you focus on areas that require more power, such as brush cutting scrub.

This whipper snipper is powered by unleaded petrol. It’s designed with a mini 4-stroke engine that consumes less petrol than 2-stroke snippers, and a one-pull start system designed to start the power tool easily and quickly. Along with their choice of two handles, this line trimmer is designed to be ergonomically friendly.

Honda attributes this user-friendliness to the Honda UMK425’s lightweight design, electronic ignition, anti-vibration extension mount, anti-flood primer system, and 360-degree inclinable operation. The Honda UML425 also comes with a new pair of safety goggles and a single harness (loop handle model), or a full operator harness (bike handle option).

Points of praise for the Honda UMK425:

  • Many reviewers professed to having bought their lion’s share of line trimmers in the past, and when they splashed out on this Honda UMK425, did not regret it. One review was entitled, ‘The last brush cutter you need to buy!’
  • The durability and overall effectiveness of this line trimmer were praised – it was often described as powerful yet quiet. Some reviewers said that they’d had their Honda trimmer for up to 10 years, and were going to replace it with the exact same model when their Honda UMK425 finally bit the dust.

Other comments:

  • A few reviewers commented that using fresh, good quality petrol is paramount, and that issues with the trimmer could be caused by using stale fuel.
  • While an ergonomically sound design is put front and centre, some reviewers pointed out that the Honda became quite heavy to handle, especially when full of petrol.
