Your posting is encouraging, I have 640 hr's on my p.t. 418 no problem's
on the robin's engine so far.

Trackks9, a guy like you probably just has the magical touch. You tree farmers usually have a step up on us average joes. Plus you have Mike Stein to call for advice.

Hello everyone!

I joined because I really got a kick out of the post started this thread. It's winter, and we just had a lot of snow in the Northeast (Connecticut). I have a PT-422 that I bought new in 2000. A few years ago I moved to a neighborhood with a common dirt driveway. The neighbors have been arguing over who should take care of it since time immemorial. I bought the plow attachment, which took care of the immediate problem . The blade is terrific; I can clear the whole street in no time at all.... but starting the Robin engine is like kneeling in rice. It's almost a day now since I first cranked it over. I'm still waiting for it to start and most neighbors have already cleared out their driveways.

The PT-422 is in a 40 degree garage. Getting it going is a ritual that alternates between putting it on the charger and throwing a tent over it with a heater underneath. The battery's been through h***. It's probably time to replace it, but I don't know how to do that without removing the muffler(?). Funny, bolts fall out of the Robin engine by themselves. But I'm certain that if I try to remove the muffler, I'll snap something.

since you purchased your P.T. in 2000, is this your first issue with cold weather
start's? If your P.T. is the same as mine, you do have to remove the muffler to
replace the battery. being in a 40 degree garage, I am surprised your having starting
problem's

The tractor sat in my ex-wife's garage for several years, and until the last few, I hadn't even looked at it in cold weather. Now I fight with it every time it snows. And I guess 40 degrees is optimistic--could be 35. Ironically, last night I pulled out a generator I hadn't used in probably ten years. Same cold garage, it started on the second pull! Any warnings about taking the muffler off? Thanks!

Aim a space heater at the hydraulic tank. When it warms up a bit more, it should make your engine much easier to start.

I assume you have tried new spark plugs - they can make a difference in poor conditions.

when i replace the battery on my 422 i thought i would have trouble with the muffler but it came off and on with no problem.

Thank you all for the advice. I have kept up with maintenance; the plugs are new last summer. Maybe the real issue is I lack patience waiting for the hydraulic oil to heat up. Between my first post and this one, I took a few measurements of the outside of the oil tank with a Radio Shack infrared thermometer. At 45 degrees, I ran the battery down trying to get her to start. About an hour ago, when the hydraulic oil (and the engine) reached 60 degrees under the tent I'd made for it, the PT-422 fired up with the first turn of the key! Sixty degrees is the magic number for me from now on.

I have a 422 purchased in April 2000 with the Robin engine with about 1,600 hours on it and still the original battery. It has been starting on the first try every time I use it, it is kept in an unheated garage and our outside temperatures have been in the low twenties. No heat used to start or warm it up and have not put the battery on charge. I usually turn the lights on for about a minute to warm the battery up some give it full choke, about 3/4 throttle and it has been starting right up. If it gets down to around 10 degrees or lower I put a magnetic heater on the hydraulic tank for 4-6 hours before trying to start it.
