    Melted and fused bump head "string"

    Any chance it has this head?

    Best for hills?

    Zero turns use castor wheels on the front. Unsteered. These can be problematic on hillsides no matter twin stick, joystick, or steering wheel. A lawn tractor with steering wheel directly connected to front wheels is probably best. I’m not familiar with the lawn tractor market these days but...

    Make or break features on a zero-turn?

    To the above I would add: 1) Quality of spindles. Might fixate on fabricated decks but spindles are common replacement items. Some box store brands use blades with oddball mounting limiting selection to OE only.

    Make or break features on a zero-turn?

    Have tried one of those at my dealer. Helped but not as good as the Country Clipper. Problem is Country Clipper is having troubles and he had to drop the line.

    Make or break features on a zero-turn?

    Significant option on my Country Clipper 42” was the optional front step and handrail. I can not get on/off without. I have the joystick model.

    Is my understanding the CPSC rule is ROPS required if 1000 pounds. Agree, I want ROPS, even on my lighter 42”.

    Fuel mix question

    The more oil you use the less gasoline. Carburetor will be jetted lean if you increase oil.

    GOODBYE TO ELECTRIC

    How much is a new engine? It doesn’t really matter. What matters is how much service you get for what you pay. Consider cost of gasoline, cost of getting gasoline, motor oil, and replacement engine. Is pretty hard to accurate estimate for comparison which suggests the results are close. I...

    GOODBYE TO ELECTRIC

    EGo chargers use forced air through the battery. Don’t know if they do the same in push mowers during discharge. The battery is in a clean, closed, compartment that could have airflow. Don’t remember any filter for that compartment. 1st generation 2016 EGo mower.

    Best oil? High zinc?

    "Thermal conductivity" is not the same thing as "carrying more heat". In general the more one carries in suspension in a fluid the lower the freezing point. That doesn't help motor oil. I seriously doubt the specific heat (the property of "carrying" heat) is significantly changed from 700 to...

    The dealer often gets free freight on larger orders. Or much reduced per unit if they can send a full truck load.

    Best oil? High zinc?

    I remember Dupont suing over the use of their trademark Teflon™ while not purchasing from Dupont. Dupont refused to sell Teflon™ to Slick50 because Dupont engineers believed it hurt more than helped. Teflon™ breaks down in the combustion chamber. One of the components is HF, hydrofluoric acid...

    Best oil? High zinc?

    I am saying very few automobiles have roller lifters. My 2018 F-150 2.7 Ecoboost (twin turbo) does not. My 2016 9000 RPM Yamaha FJR1300 does not. My 2007 Prius did not. The valve springs are much stiffer than any power equipment engine I have seen. And while the Yamaha does over 4000 RPM quite...

    Best oil? High zinc?

    Zinc is the "synthetic" of lawnmower motor oil marketing hype. ZDDP is a consumable lubricant of last resort. When contact pressure pushes through the oil film. When high lift, high speed, strong spring valves use solid tappets on camshaft, ZDDP is needed. Lawn equipment engines are not high...

    Grass isn't cut between the blades.

    Wasn’t thinking your stripe was so wide. Your center blade is in front of the side blades, the cut overlaps but the blades can never hit each other. An uncut stripe can be produced cutting during a tight turn, Am agreeing with others your center blade is slipping on the belt, or pulley...

    Non ethanol fuel question

    Water is in contact. Water plus oxygen makes rust. Clearly you have never disassembled a carburetor or fuel injector which which sat unused with water in ethanol gasoline. Ethanol gasoline phase separation is the ethanol + water falling out of solution. If only water fell out no one would...

    yardman rider shutting down when blades engaged

    I could start it just fine with butt in seat and PTO off with parking brake set. Agree, I think there is an interlock. Don't think there is a mechanical connection, but it sounded like the blades were wedged when I tried to start them. Doesn't really matter. Lesson learned.

    yardman rider shutting down when blades engaged

    Uh, I did that the other day on my Country Clipper. Parking brake was set. I don't know why the engine cut out when I engaged the blade PTO just because the parking brake was set, but it did. Guessing it is a deliberate design decision.

    Non ethanol fuel question

    The product is called Heet, and it is primarily ethanol. So ironically today people are complaining about that which they used to buy and deliberately add. Because it was better to suspend water in gasoline to get it out and through the system than have it puddle, freeze, and block fuel passages.

    Non ethanol fuel question

    And ethanol allows the water to carry in the fuel, exposing the entire tank not just the bottom. This is the problem with ethanol + water in carburetors. With pure gasoline a drop of water in the carburetor kills the engine. In ethanol, it simply leans the mixture, but probably goes right...

    Non ethanol fuel question

    Ethanol is not "destroying tanks". In 1984 I had to buy a new gas tank for my Honda motorcycle because it somehow had over 3/4" of water accumulated in my attached garage over the winter. Formed a nice line of holes through the tank at the gasoline/water line.

    Non ethanol fuel question

    Ethanol is not good. But isn't The End Of The World. The problem with small engines is the simple fuel system exposed to moist air. The problem is in how small engines are often left out in the weather. Ethanol-free gasoline still accumulates water, but the water doesn't mix. The water can be...

    Non ethanol fuel question

    Air gets in automotive fuel systems, it just doesn't flow in and out getting replenished with fresh moisture. And then there is the 2004-2009 Prius whose fuel tank consisted of a bladder/bellows in a plastic case. Very little air volume over the fuel. As fuel was consumed the bladder collapsed.

    Non ethanol fuel question

    The only harm ”from” ethanol is that it carries water in solution, then carries that water into the carburetor. If allowed to sit it will do nasty things. No additive or treatment does any good. Small engines have ventilated gas tanks, open to the atmosphere, open to collecting moisture...

    Non ethanol fuel question

    Just buy E10 from a high volume gas station. Only buy a month or two’s supply at a time. Don't store the can on cold concrete because cold fuel with warm moist air condenses moisture from the air no matter ethanol or not. 90 octane (sic) won’t hurt anything, won’t help. When engine is designed...

    GOODBYE TO ELECTRIC

    Yes, that is why they didn't last very long. Flooded lead-acid batteries wear very fast when subject to a deep discharge. Lithium-ion doesn't like operating at full charge or low charge but is very happy in the middle. LiFePO4 costs less than lithium-ion, likes a full charge and discharges don't...

    GOODBYE TO ELECTRIC

    That is the old Craftsman trick of "upgrading" to higher battery voltages every few years. Sears sure is a success to be admired! EGo did a very good job designing one battery, right, the first time. Everything is 56V, and the same connection is used for all.

    GOODBYE TO ELECTRIC

    The EGo battery warranty is 3 years. Am still using my original 7.5Ah from 2016. The worst thing you can do is leave it on the charger 24/7. Second only to leaving it out in freezing temperatures. My 2013 Tesla Model S 85 still had 93% of it's original battery capacity remaining when I passed...

    You couldn't bother reading the link before shooting off at the mouth? The supposed ban is of "new car sales".

    Best Oil To Use For Kawasaki

    The GL1800 was built in Marysville, OH. But if these "rice burners" can thrive on the not-really-reduced ZDDP then why not a US-built rice-burner Kawasaki at much lower RPM? My point is that if excessive ZDDP really is necessary that it is a design defect, other engines of much higher...

    Best Oil To Use For Kawasaki

    Zinc isn't limited by the EPA, it is phosphorous which is limited. Zinc only because they choose to use ZDDP in motor oil. Most "automotive" motor oils have 700-800 PPM of ZDDP. 1500 PPM becomes acidic so even the "zinc rich" oils are limited to 1100-1200 PPM. You ain't looking. Air cooled...

    Best Oil To Use For Kawasaki

    Every motor oil has zinc in it. Most every engine ever made has (by your definition) “solid” lifters even those with hydraulic lifters. The issue is whether the spring rate and lift of the cam and RPM drive pressures great enough to push through the oil film. This just does not happen in power...

    Neither Kohler nor Kawasaki have published a specification of what they expect of an oil... other than the video on Kawasaki's site saying to look for a genuine API rating and how they also submit to JASO for real testing (a snub at Shell who self-certifies a JASO MA rating on certain varieties...

    Best Oil To Use For Kawasaki

    I find most everything that is brave enough to list zinc content has at least 800 PPM. So, we are supposed to believe zinc works magic in lawnmower engines, trust that lawnmower-specific motor oils have massive amounts of zinc, yet no one puts their reputation on the line to enumerate how much...

    RPM for a 22" residential push mower

    I don't think HP/torque is the primary concern about RPM. In general the cut is better at higher speeds, so while the big deck of a rider has it's disadvantages the faster blade speed over a walk-behind has advantages.

    Yup. It was cutting, blowing, and some clips, but not much. That is what had me confused for a bit until thinking I might lower the deck 1/4” only to find it fully raised.
