Is this the kind of grease gun you need?

    any grease gun will work. the small ones with the flexible hose are good for the mowers cause you can get to all grease fittings usually with no problem. but get those fittings greased now. thats why there there. if your in the biz you want your stuff as maintenance ($) free as possible, greas'em offend.

    I agree with bigtex about the flexible hose. I use machine grease. You can get it an autoparts store.


    When you are done with that then tap the air filters out.

    Its daily routine maint.!

    In 19 years of mowing, I"ve thrown 3 spindles.

    One was a sealed spindle (non-greasable), one got fishing line into it, and one dropped with about 100 hours on the hour meter on a new machine.

    I grease my mowers every 150-200 hours, usually about 4 times / year.

    It's just my experience, not saying it's for everyone.

    Also, I use 100% synthetic, waterproof lithium grease from Amsoil.

    I wouldn't wast time with a "mini" type grease gun. For the cost it's the same to get a normal sized model with a flex hose. It's easier to get grease for them, and they run out of grease fast being the full size ones, can't imigine how breifly a mini one would last...

    I also grease every 50 to 100 hours. Greasing everyday is rather silly. you are just pushing out grease all the time and wiping it off doing that. Plus many things that have bearings with seals can't tolerate being greased that much. Seals blow out and then they wear out prematurely because dirt can get it.

    Maybe the spindles dont need it but the casters need daily greasing and so do my sulky bearings. More so in dusty and dry conditions. Nothing silly about proper maintenance.

    I have had both small and big grease guns. get a big gun with the flex hose. I grease quite often, about once per week....especially the casters.
    When using the small gun, I will easily go through one tube of grease sometimes almost 2....(2 mowers with Jungle Wheels).

    thanks guys. I'm going to get a full sized grease gun and try and find synthetic grease.

    Now how about the oil. I'm going to be changing that too for the first time on this machine. I've done it lots of times on the smaller one of course but, I want to use synthetic on the 36".

    I know certain people (Like Topsites) says he uses 10w30 but my understanding of that phrase is that when the oil get hot is acts like 10. Lawn mower oil, the regular stuff is SAE 30 and when it gets hot, it always acts like its 30. I'm kinda perplexed about that.

    Ideally I would like to put everything on synthetic oil, including my trucks. Since synthetic lasts longer and I hate oil changes.

    IN short, is 10w30 synthetic ok (if not superior) for 15 HP lawn mower engine?

    I was in the oil biz for a few years....here's he deal.

    A multi-viscosity oil starts out thin and then thickens up as it gets hot, that means a 10W30 oil is a 10 weight (thin) when cold and turns into a 30 weight (thick) when hot. The reason for this is called flow rate, the lower the viscosity (thin) the faster the oil spreads throughout the engine on cold start ups thus lubricating everything quicker. Then when the engine reaches operating temperature, the oil increases viscosity (gets thicker) to increase oil pressure thus increasing horsepower.

    What should you use in your mower....I ALWAYS use what the engine manufacturer says to use...period. If they say use conventional 10W30, don't assume that synthetic 10W30 will be better just because it makes YOU feel better. Sometimes synthetics cause harm to certain engines ( flow rates of synthetics are MUCH faster and can flow right around seals in engines not built for them causing leaks, lower oil pressure, and less power. Believe me, it is always safer to use the recommended oil....but you can always contact the engine manufacturer with your model number and serial number and ask them if its to your advantage to use synthetics.

    Hope this helps!!!

    That really does help. I thought it was the opposite, that as the oil got hot it got thinner... seems counter intuitive. It also (at least in my mind) bolsters the case for synthetic because because it will get hot and then start acting like a 30 weight.

    That SAE 30 oil is as expensive or more so, then synthetic.. I better get it from the horses mouth like you say.
