FAQs

  1. Is it a flail or rotary and what color is it?
  2. Look for manufacturers tags (serial / model#).
  3. Is it hydraulic or PTO driven?
  4. How many blades does it take and what size are they?
  5. Are there any markings on the blade?
Due to the large number of parts that we supply, you may not see the part number you want.  The best thing to do is give us measurements for your blade.  Our dedicated staff will be happy to help you find the part you need!
The best way to determine the cut of your mower is to count the stations on the cutter shaft and measure the blades.
Changing to different blades can be done in some cases as long as there are no interferences. The blades should not touch each other and all the blades should be the same type so there are no balancing issues. You also want to make sure that when the mower is in motion the blades do not hit the bonnet (mower shell).
Square
• With four sharp edges, square trimmer line cuts faster and more efficiently. The square-edged line works well if you have tall, thick and heavy patches of weeds. The downside to square line is it breaks off quicker when it contacts stones, fences, curbs and buildings. Square line also has a tendency to jam in the spool retainer if the line isn’t replaced properly.Round
• Round trimmer line is smooth and will wear down less quickly. Most cutting occurs at the very tip of the line, so when round line contacts hard surfaces, like sidewalks or trees, it will break off less. The round line is also simpler to load into the spool retainer during line replacement, which may save time in the long run if you have a lot to trim.

Hex (aka Star)
• The Hex (star) or multi-sided line uses this shape to make cutting even faster. Again, the same rules apply with the square model string: quicker cutting but faster wear.

Diameter
• All of the lines come in a wide variety of diameters. Industry standard on most models is .080 millimeters. This diameter measures the thickness of the line. If you’re having problems with the square line breaking too quickly, you may increase the diameter size one increment. If, on the other hand, your line is jamming or fusing together inside the spool retainer, you can reduce the line size by one notch. Check with your owner’s manual for maximum line diameter; overloading can damage the drive shaft.

Considerations
• Square trimmer line is quite similar to round trimmer line, and it really comes down to preference and feel. Their difference lies in the amount they will wear out. Consider how much you need to use the trimmer, over what physical conditions, how long each job will take you and how often you will need to replace your line. Both lines are relatively inexpensive, so you can experiment for the best results.
