  • Fix your bad design if you do not the China company will take all customer from your company.
Size: 450S
The 450 S rancher gas I just bought was not reliable , there is a plastic washer to support the bar thickness around 1/4 inches after engine ran an hour the white plastic getting hot it melt down, result the bar starts to lose , your company needs to redesign the washer made by aluminum, I had to made one piece of aluminum washer to replace the damage washer, It works good now, your company needs to send a new aluminum washer for the buyers, to make them happy. ... show more

  • Dont do it , not what they used to be , not even close
Size: 450S
Husqvarna products are not what they used to be, I’ve had a few Husqvarna mowers in the past few years that broke easily and quickly, then when you try to find parts they’re discontinued. This chainsaw is no different. My last Husqvarna chainsaw I’ve had for 25 years and nothing ever went wrong with it other than new bar and new chain, I had this Husqvarna chain saw for one hour, the chain flew off destroyed the chain, destroyed the bar, damaged the chainsaw itself. ... show more

  • Chain always falls off
Size: 450S
Was great for the first 30 minutes using this but chain came off and damaged the saw and ruined the chain. Luckily bought 2. Put second chain on and within 2 minutes fell off again damaging the new chain and cutting through the metal guard on saw. Super dangerous. After happening 3 more times it damaged the 2nd chain. Not reliable and dangerous. ... show more

  • Husqvarna Horrible
Size: 450S
Hysterical! Chainsaw new in box and did not have the guidebar to put the chain on. And no, it’s not the head unit model only. It came with the saw the guide bar cover the chain the wrench but no guidebar. Rented a wood chipper for the weekend and now have no saw to cut the trees. Disgraceful
