Weeze. I'm not farmiliar with 4 stroke string cutters. Are the oil changes similar intervals to our mowers??
i think it's every 50hrs....similar to a pushmower engine. i do it 3 times a year. about every 3 months. (grass growing season is about 8 months long here)
i would say i use the trimmer less than 5hrs a week total. most yards i use it for 5-10min. a few maybe 15min.
i also use full synthetic mobil 1 10w30. it only uses 3oz of oil so not much at all. takes about 5min or less to do an oil change.
with fresh oil (i change it at the end of each season) i use it march-may then change it and use it june and july then change it and use it august-october. wait 3 months at the beginning and the end of the season since i'm not doing as much work since it's a slow start and a slow end to the season.
i'm always surprised at how few LCO's use the honda or husqvarna with honda engine trimmers. i think everyone is just stuck on 2 stroke. i even ask the dealers they say everyone says the 2 strokes last longer but i call BS on that. i don't know anyone that has a 2 stroke trimmer that has lasted 15 years with zero problems.
i think most people just don't take care of their equipment.
it's kindof sad because the 4 stroke was "the next big thing" that came out about 15 years ago or so. it never caught on or maybe everyone just said well we can't make one as good as honda so we're not even gonna try. :laugh:
it's kindof like 4 stroke will be overlooked and people will go from 2 stroke straight to battery in the next 5-10 years.
in almost 15 years i've only had the primer bulb and fuel lines replaced once. (just last year after 13 years)
it's still using the original spark plug. i've never touched it. i checked the valves once after 12 years and they were still set perfectly so they've never needed to be adjusted.
it still cranks 1st or 2nd pull every time.
this is why i will probably not switch back to 2 stroke trimmers. the honda has just been too good. the 4 strokes also are a lot quieter than 2 strokes. if i was gonna get a 2 stroke i would probably get the echo 266 PAS system though with trimmer and edger attachments.
for now i'm using the husqvarna 324ldx with trimmer and edger attachments. it's called the husqvarna 524LK now. they changed the numbers. the 324L is just the trimmer only. ( was called the 224L before)
my husqvarna is only 5 years old so i got at least 10 years left out of it. :laugh:
my honda will be my backup trimmer even though i used it every day this year. i figure after 15 years i should give it a break and just keep it as backup.
