That may be your opinion.. but it hasn't been my experience.
I have a "junk" 5' KK rotary mower from TSC.. have had it 5 years almost now.. pulle dit behind my ex-NH 1920 .. that tractor will tote a 6' mower.. so the 5' was getting a work out. I usually was cutting stuff taller than the tractor. It found it's fair share of buried lumber, and skinned more ant hills and mole hills than i can count. Probably been thru a couple shaer pins a season.. Pto shaft is nice and tight, and oem shield is still intact.. no leaks on the gear box.. OEM set of blades is still in perfect condition.. OEM paint hasn't worn thru yet.. though is scratched deeply in places. NO rust ont he deck.. slight surface rust from scratches onthe a-frame... no bends, etc. Hud or rear laminated tire is fine.
Not bad for a 500$ mower... I don't baby it at all. The tail wheel mount has been known to knock over a fence post or two as well.
Last year I upgraded to a 10' howse mower.. that's another one of those "junk" mowers. I mows 1" woody stuff and tall brush, and 3' deep weeds and grass like butter. I've accidentally knocked a sweet gum tree or two over ( 3" / 15' tall ) and made mulch out of it. That mower is toted by a Nh 7610s.. again..way more tractor than the mower needs..
No leaks.. no blade problems, or pto shaft problems.. tail wheel hubs ar good, as well as the tail wheel rocker lift shaft. Deck and 3pt frame is massive.. 1/2 inch metal in some areas.. mower weighs a couple thousand pounds... part of their heavy duty line... You do realize that these "junk" dealers offer many lines.. ranging from economy to heavy duty?
My stepfather has a 6' howse rotarty cutter.. economy line.. pulls it with his 50-hp JD 2240.. mower is in rough shape now.. but it's over 10ys old. still oem blades seals and gearbox.. no leaks.. deck has been damaged by running into trees and stumps. Almost lost a blade bolt fromt he carrier, and let the blade put an arc shaped gouge int he deck.. but didn't penetrate... So, in the 10+ years.. it got 1 new blade bolt and nut, and a weld patch on the deck... pretty good for a junk 500$ mower eh?
You are also overlooking an important feature of an economy mower.. weight. many tractors may have the hp to run.. say.. a 5' mower.. but are on the light side.. or have a lift that may not lift a huge heavy duty mower. That's where an economy mower comes in.. they have less metal, and are lighter / lighter duty. An old ford 8n can spin a 5' mower.. bt the rear lift is only good for about 750# before the front end comes off the ground.. and then if you have weight on the front, and an excelent hydro system, you might get 1000 to 1200 punds out of it.. but that is reaching.. my guess is closer to 900-1000#. I've seen heavy duty 5' mowers that exceded that weight... those woulddn't be an option.. etc.
Based on price.. I can buy a "junk" mower.. use it till all the goods gone, and then repalce it with another, say at the end of 12 years. that puts me with a brand new mower after 12 years of use.. and with the purchase of the 2 mowers.. I'm still in for less cash than if i had bought a single high dollar unit, which at the end of 12 years should still be running ok.. though isn't new... etc. I'll go with thos numbers any day...
