I dont know about the mowers but i have 3 Talon chainsaws . 1 x 38 cc 35 cm bar and 2 x 55 cc 50 cm bars .. living out in the bush and only having wood heating they cop a fair workout .. all three saws have seen 2 and half winters so far and apart from sharpening the chains i havent had to touch them .. will relace the bars before next winter but they start first go .. run for hours on end and have caused me no problems at all .. touch wood
