Owner reviews note that it starts reliably and cuts well, but some components feel less robust than premium brands. For professionals starting out or those needing a second mower, it is a solid, cost-effective choice.

What to check before buying a petrol lawn mower for professional use
Choosing the right petrol mower for professional use requires careful consideration of several factors. Engine displacement is critical, with 160cc to 200cc being the sweet spot for most jobs. Deck size should match the typical lawn size; 46cm is standard, but larger decks save time on big areas. Build quality, especially a steel deck, is non-negotiable for durability. Self-propelled drive is essential for reducing operator fatigue over long days. Finally, consider the dealer network and parts availability; Stihl and Husqvarna have extensive support, while budget brands may have limited service options.
Mistakes to avoid when buying a professional petrol mower
A common mistake is choosing a mower based solely on price. A cheap mower may save money upfront but can cost more in repairs and downtime. Another error is ignoring the weight; a heavy mower can be exhausting to use on slopes or uneven terrain. Professionals should also avoid models with plastic decks, which are less durable than steel. Finally, do not overlook the importance of a good warranty and dealer support, as these are vital for minimizing downtime in a professional setting.
