    I think Mossroad is on to something. You have to heat up the engine compartment to help with the engine start, not the hydraulic tank.

    I aim my 5000W 220V space heater in the back end of the engine compartment (not close enough so stuff melts), and let that sit for an hour. Seems to make a big difference. Little 1500W heaters are useless when the garage is at 20F.

    I agree with you MossRoad. Would love to be able to get the engine running, or at least know what the problem is with out sinking a boat load of money into it.

    Terry told me last week the Robin is a great engine, however it is one of the worst when it comes to cold starting. Aren't there other brand engines that are good engines which start in cold weather climates without going to extremes.

    Hit your local thrift store and get couple of big heavy blankets, then use them, a $20 electric "milkhouse" heater (we have this one and it works well) and possibly a couple pieces of plywood to get things toasty warm (build an insulated "doghouse" around the engine/pump area and let the heater run till everything is toasty warm). Then try starting it.

    seems like this would be doable. I picked up one of those heaters at a thrift shop too, about two dollars, now it's in the well house.

    Ummmm....

    If you are getting a space heater near gasoline, you want to be really, really careful.

    In general, the ceramic heaters are considered safer because the heating element is at a lower temperature compared with the milk house heaters. In all cases, you want to be concerned about a thermostat or switch that might arc.

    Personally, I would stick with the magnetic heaters or the space heaters at a distance. I would point out that most of the oil recirculates in the drive circuit, so even if the pump and/or hydraulic tank is warm, as soon as the oil goes out to the wheel motors, it will get cold until the drive circuit warms up.

    As an aside, the hydraulic pumps and motors have very tight tolerances and are designed to work at a constant temperature. TBased on my limited understanding, I think that the way that we use them is decidedly off label. Once a PT is started in the cold, I would give it a chance to warm up throughout before pushing it. I think MR's method of starting the PT and then letting it idle while he shovels is a great idea for longevity.

    Oh, another vote for getting the engine taken care of first. :-)

    All the best,

    Peter

    I took a video about two weeks ago of me starting my 12year old 2001 PT425 Kohler command engine with 500ish hours and the original spark plugs at 9 degrees in my garage. (Its too big to post here, but I'll figure something out eventually) Anyhow, I didn't use any starting fluid nor did I put it on the battery charger for the past two months. Had I had two hands free to operate the throttle and choke, it would have started in about 5 seconds. However, I was trying to hold the iPhone with one hand and it was not possible to manipulate the throttle and key at the same time. Once I put the camera down and used two hands it fired right up.

    Could it be something as simple as the starter motor on the Robin is too weak to turn the engine fast enough when it is pushing cold hydraulic fluid?

    Has anyone tried using a booster battery with jumper cables on the Robin equipped PT to see if they can get some more amps behind the starter?

    I use an old hair dryer. I put a shop vac extension on it maybe two foot long ,three or four inch dia. I kind of latch it onto the hydraulic pump or aim it at the pump,shut the hood on it and throw an old blanket over the dog house cover. Let it run for about twenty minutes or untill the pump feels warm. starts up every time.pt 180 robin 18hp.

    Robin put a bigger starter motor on their engines starting about 4 years ago. The PT in question undoubtedly predates that. I have the old starter motor on mine.

    So yes, that could be part of it.

    Not too worried about fuel vapors in 20-30F weather. I use the space heater all the time. Works way better now that I have a 5600W 220V version (insert Tim the Toolman grunt). With the gas cap on the tank, nothing is going to happen.

    Obviously keep it at least a foot away; don't want to melt anything.

    We used to do something similar with airplane engines only it was a propane burner. But no reason it wouldn't work. Just make sure the hose is able to take the temps and won't burst into flames and light the blanket on fire.
