i have riding lawn mower and starter kicks out and turns motor one turn then stops..i hooked starter to a charger and it will keep running fine so i dont think its the starter..what should i do next
Answer
If the battery test good and all of the connections are good 12 volt source, check the valves in both overhead valve or in block style valve. Meaning, an overhead valve has a head with valves in it that you can take off, push rods, and adjustable rocker arms ( the valves are not contained with in the block). You should also check them on a valve inblock style on some series and brands ( ex. if it is like a k series Kohler they have adjustable tappets in them that have a clearance that needs to be set). I forgot to mention this style of motor contain the valve in the engine block You can tell by the head just being flat and just having spark plug hole and no moving parts in it. If it is a valve in block style or overhead, and all other conditions are met valves set properly,no electrical problems. This could maybe have a compression release problem. There is a spring and a lift pin on the camshaft that releases compression from the piston chamber. It is on the cam shaft and through cintrifigal force allows weights through turning rpm to move a pin and in turn allow the valve to go to the open position allowing compression to leak down and not dead head while starting so it can be turned over easier. After the engine starts the weights fall back in and the release is no longer holding the valve open and the valve tran operates normally. Usually if you put a charger on it will start fine. With this problem the starter has unlimited amperage ( whatever the charger is usually 300-600 amps if it a big one) to turn that motor over. Most mower batterys will carry a lot less cold cranking amps. Just remember that testing your cables can be tricky checking them with an ohm meter is a bad reading because if just one strand of the cable is touching you will get a good reading. Check the draw of the starter with an inductive pickup to see how many amps it is pulling if it is pulling just a few it is cable and connections or starter prob. If it is pulling a lot could be starter problems or it could be a compression problem because the starter is having to work double time to try and turn that motor since the cylinder is building up full compression. I have had the compression release in many cases cause a customer to buy a new starter, cables, and switch when he didn't need em. He put it on and it didn't make a difference. I am into diagnosing not spendin money. Hope I helped you diagnose it and I explained it so you could understand p.s Just dont want you to spend money on something you dont' need!

Why are lawn mowers so expensive?
Taylor
I've been wanting to start a mowing business but I've been having trouble figuring out the prices for mowers. You can buy a nice self propelled 21" mower for $300 but then if you want a 32" mower suddenly the price shoots up to about $1500. Why do lawn mowers cost so much? You can buy a riding lawn mower for the price of a 32".
Answer
Mower manufacturers have mowers they usually sell to home owners, or people that just mow for themselves. Then they have their "commercial" line of mowers, always more expensive. Just know, they all make the grass shorter.
Commercial units are usually built a bit stronger. Maybe a better motor with longer maintenance times, heavier built decks and blades, bigger gas tanks, oil filters to increase longevity. If I was starting out, I would go to craigslist(dot)org. I have always found several mowers, riders, commercial, and push mowers, as well as trimmers, trailers and any other tool you might need. Most people live close to 2 to 4 markets of CL that offer a variety of products.
So, buy used, as you develop the business, you will see and appreciate specific models and brands, then you can splurge on your favorite power tool.
