Customer Reviews
Customer Review: This unit seems to work well, although I prefer a longer unit and I understand that they now have a 20 inch unit that fits Husqvarna at a reasonable price so if that’s what you’re after I would get it this particular unit here is too small to fit the Husqvarna Straight shaft.
Customer Review: I have several of these from kerlista for the UMC435. In fact, I believe I have every single attachment now. Each one (including this one) is quite well made. Each one seems to match the OEM material (metal) and build quality of the trimmer itself. It seems suspiciously similar to a Honda built.

Frequently Asked Questions
Q: What are the main advantages of a 4 stroke string trimmer over a 2 stroke?
A: 4 stroke string trimmers offer several advantages: they don’t require mixing gas and oil, resulting in cleaner emissions and less smoke. They are generally quieter, more fuel-efficient, and tend to have longer lifespans due to better lubrication. This makes them a more user-friendly and environmentally conscious option for most homeowners.
Q: How much power do I need in a 4 stroke string trimmer?
A: For typical residential lawn care, a 4 stroke string trimmer with an engine displacement between 25cc and 50cc is usually sufficient. If you have a very large yard with thick weeds or brush, you might consider a model towards the higher end of this range or even slightly above.
Q: Can I use a 4 stroke string trimmer for heavy-duty brush cutting?
A: Yes, many 4 stroke string trimmers are designed for heavy-duty use and come with brush cutter blades. Look for models with higher engine displacement (e.g., 40cc and above) and features like a metal blade attachment option for tackling thicker vegetation.
Q: Are 4 stroke string trimmers heavier than 2 stroke models?
A: Generally, 4 stroke string trimmers can be slightly heavier than their 2-stroke counterparts due to the additional engine components like a separate oil sump. However, manufacturers are constantly working to optimize weight, and many modern 4-stroke models are quite manageable, especially those with ergonomic designs and comfortable harnesses.
Q: What maintenance is required for a 4 stroke string trimmer?
A: Basic maintenance includes checking and topping up the engine oil regularly, cleaning the air filter, inspecting the spark plug, and ensuring the cutting line is properly installed. Regular cleaning of the exterior and proper storage will also prolong the life of your trimmer.
