Q: Is there nylon covered blade attachments you can buy for this walk behind trimmer to handle the thicker brush instead of using the trimmer line?
by Barry from Minnesota on May 07, 2013

A: Barry - sorry, but none of the walk behind trimmers that we sell can be converted to use a brush blade.
by Joe, Product Expert
Q: Does this trimmer have an automatic string (line) feed or is it small little hunks of line that you need to replace manually if it breaks off? We have a piece of property (not big) that is a mixture of weeds, volunteer trees (buckthorne) and small top tree roots, would this be a good trimmer to use; as I don't want to mow it with the blade mower. Thanks for the help.
by Beth Kryzak from Illinois on July 21, 2011

A: Beth - all of the gas walk-behind string trimmers that we carry (including the Husqvarna HUS625HWT) would use multiple strands of pre-cut trimmer line. These strands do need to be replaced by hand when they fray or break off altogether. However, the pre-cut strands of trimmer line used in this type of trimmer are much thicker and more durable than the typical trimmer line found on hand held string trimmers. As for the property you have described, I don't think any of the gas, walk behind string trimmers are going to "tame" your vegetation. I don't think you will be able to trim back or cut down any of the volunteer tree's or buckthorne - I'm not positive, but I'm pretty sure these are going to be too tall and too thick around for this type of trimmer to handle effectively.

Q: How do I purchase replacement blades for the HUS625HWT walk behind string trimmer?
by Patty from Washington on June 26, 2011

A: Patty - this product does not use "blades". It uses a heavy gauge vinyl trimmer line. Here is what you need: high wheel trimmer line

Q: Todd, I'm about ready to order the HUS625HWT, walk behind string trimmer. Man I know this is gonna help keep my acre of weeds under control. Question: I would like to purchase extra line. Do you stock any, and what size is it? Thanks man! Bruce
by Bruce from California on June 19, 2011

A: Bruce - we do carry replacement line for our walk behind gas string trimmers. It is a .155 diameter line, and it comes in a package of pre-cut lengths that will fit most walk behind gas string trimmers Trimmer line

Q: I am considering buying this as a replacement to a push mower that just died.
I have a rider for most of the mowing and I need this for our vacant property for the tall stuff. Do you think that this would be okay for light mowing on a small yard? I don't see the sense in buying another push mower if I have this. Does it give a fairly smooth cut on regular yard grass?

by Vince from Michigan on June 14, 2011

A: Vince - a walk behind string trimmer really isn't designed for standard grass mowing. It will definitely work for this purpose, but because you are doing the cutting with a series of thin, flexible trimmer lines instead of a rigid steel blade, you may find it difficult to cut your grass in an even, smooth manner. The cuts to your grass may be somewhat uneven. If you are looking for a smooth, even cut for your yard grass, you probably won't be happy with the results from a walk behind string trimmer.
by Joe, Product Expert
Q: Can this string trimmer be used on an unlevel surface, such as a hillside? I am looking for something mainly for that purpose but also to do trimming between hedges.
by Kerry from Illinois on June 13, 2011

A: Kerry - yes, these walk behind string trimmer can be used on uneven surfaces and hillsides, as long as the slope is not greater than about 20 or 22 degrees. You will also be providing the "horsepower" to push one of these up and down the slopes, as none of these units have a drive system.
by Joe, Product Expert
Q: im looking for a walk-behind trimmer i got one now its great i would like one that starts with a key other the dr i dont see any other is this true
by Lois A Brown from Missouri on June 12, 2011

A: Lois - none of the walk behind string trimmers that we carry have an electric start feature. This is not a common feature on a walk behind string trimmer.

Not A Good Product Company Takes Forever To Pay Repair Bill
Purchased this trimmer at Menards. They do not take returns on any item containing gas. I only used it for 15 minutes one day. Went to use it the next day and it would not engage to spin. Took it to the nearest repair shop designated by ARDISAM and there it sits for the last 2 weeks. It is repaired but waiting for payment to be authorized. My weeds are now huge. I feel as though I have simply thrown my money away. Never again on an Earthquake product.

Belt Will Not Stay On.
Bought this trimmer at Menards and worked for twenty minutes before belt came off. Repair shop is ordering belt, bearings and pulley. Something is badly wrong.
Pros: Junk
Cons: Low Quality

Belt Will Not Stay On Track
Bought at Menards. Got it home, started great, took it to work, 15 minutes in changed rope. Went to restart and would not engage. Found belt had come off track. Re-set belt per the diagram in the manual. Engaged immediately, then came off track again. Tried 3 more times with same result. I'll try a new belt, but it seems this may be a design flaw, considering the only other review had the same issue.

Have not tried to return, but my guess is they will not take it, as it is a gas... more
