It is 10 miles to town from here & 15 from the edge of my service footprint.
SO that is a 20 to 30 mile round trip , not much change out of 1 hour.
Set fee servicing
Push mowers - $ 45 + parts
SP mowers = $ 60 + parts
Tractor ride ons $ 350 + parts
ZTR's = $ 400 + parts
I only know of one tech who does home servicing of push mowers and he charges $ 30 Flat fee, filter, plugs , oil & blades included .
He also replaces starter ropes ( no extra ) and wheels +/- bearings for extra
And this is to SERVICE a running mower and he does all of them twice a year.
However he does them in runs so he will do an entire street / suburb in a single run over a day or 3
He buys the oil in 44 gallon drums directly from the blender and the filters in hundreds direct from the factorys in China so gets them for a few pennies
Blades come through the wholesalers in workshop packs of 1000 pairs (we use swing back blades ) , don't know where he gets bar blades from as very few wholesalers keep much in the way of Yankee push mower bar blades down here .
Thus he is only a couple of minutes between jobs and can knock over up to 40 / day on a good day
And because he sees every mower every 6 months knows exactly what is needed to be done to each of them
Calls himself "First Pull Mower Servicing" does not advertise & works a 5 day week , cash only .
I get some cast off repairs of hand helds for some of his customers that are reasonably close ( about 15 miles away )
Tells me he has around 2500 customers
I bump into him now & then when picking up parts from one wholesaler.
Now I can see Honda SP owners paying $ 60 / year for servicing mowers that are all north of $ 1000 be he reckons about 1/3 are supermarket home brands that were $ 100 to $ 200 brand new
