I need a replacement, spring shaft for my grass cutter

grass,string or vines can get wound around the motors shaft, you will need to take off the spinning head to remove debris from motors shaft

50:1

100ml of oil in 5L of petrol

Norman PRICE THE WORD HUNTINDG IS TRUE THE MOTOR IS LOOKING FOR FUEL ON SOME MOTORS YOU ADJUST THE MIX ON THE CARB CHECK THE AIR FILTER TO SEE IF PLUGED ON A FOAM FILTER YOU CAN CLEAN ON A PAPER YOU WILL NEED TO REPLACE. ANOTHER THING IS HOW OLD IS THE GAS . TODAY THE GAS IS ONLY GOOD FOR A MONTH,

turn it upside down clean all the dried grass away from the holes around cutter shaft, apply a few drops of 3 in 1 or similar oil to shaft
bearing. Clean all dried grass from holes around top of motor casing
re try machine if it is not faster than before motor brushes are worn
and its time to buy a new one

Brushcutter kits should fit this model however it is quite a small engin within the range so may not be advised and it could put extra load on the engine and drive shafts

You're a bit vague in your problem description here, but I'm assuming you mean that when you give your machine gas that the cutting head will not turn. First I would check the cutter head to be sure that no trash has wound itself around the shaft preventing the head to turn...if that is not the problem turn the cutter head by hand and check to see that the bearing inside the cutter head has not seized, it should turn freely with no noise....if no joy check the cable which runs through the shaft from the engine to the cutter head it may be broken or frayed, also check to see that there are no problems with the clutch (broken springs, broken pads, or a broken key) that should do it ...hope this helps...;-D

I had this same problem. It got to the point where mechanisms inside the shaft actually melted. I took it to a repair shop where they were able to fix the problem, or so I thought. A little while later the entire shaft separated from the handle one day while I was trimming. Upon investigation, two small pieces of plastic on the inside of the handle are what held the shaft and handle together. The overheating problem melted these plastic pieces off. I now need to order an entirely new handle assembly, which is roughly $7 from Ryobi's website.

I recommend that you have your brush cutter serviced immediately before the problem progresses as it did with me. It is likely already too late.

I am very displeased with this machine. I purchased it brand new in 2006 and it has been constant problems since then. It is billed as being able to sufficiently cut through thick brush, but in reality cutting brush seems to damage the machine. After this experience I will likely never buy another ryobi product. The craftsmanship is very poor.

First take the head off and look for grass, weeds and string wound up in there. A lot of times that's the problem.

Next, with the head off and the switch in the off position, pull it over a few times and see if the shaft spins. If not, could be a broken shaft or a bad clutch.

Check for debris caught under the deck. The motor may be getting ready to quit. The machine may need a replacement belt. Be careful and unplug the machine before checking.

Hi, I have a Ryobi brush cutter and the engine has a tendency to move up and down the shaft. It also rotates around the shaft
