Sounds like your just beatin aruond out back,So do what you want,or whatever your abilty allows.If we all just left every thing alone ,we'de be racing at 10 mph would'nt we.If we used only 'MOWER PARTS" on are mowers we wouldnt get far,mower parts are made to mow,thats why we use alot of the cart parts we use.(bearings,carbs,axle...)Then thats also why they regulate us.Good ol american engineering can get carried away,we all need a leash once in awhile. On the same thought,one of my neighbers built a VW 4cyl. powered john deere,all atachements still work and it is hydro,a bit bulky and slow and isnt good for much,But looks awsome.
