Sorry, no plow experience, but I'm picturing your 3 wheeler as a 2 wheeler with a ski/plow combo out front!

Any Meyers or Western dealer should be able to provide the correct fluid.IIRC Meyers fluid is greenish blue.Western plows generally take ATF.

ATF will work fine if it's a Western plow not so if it's a Meyers.

The hydraulic oil in Wal Mart, K-Mart, Meijer works in either plow.

Hydraulic fluids, like most oils get very thick in the cold. Then the equipment becomes sluggish and the seals or hoses break.

Since I would assume you will use it in the snow, I would not put standard Hydraulic fluid in it (Viscosity index around 100). There are multigrade hydraulic fluids (VI around 150). There are Tractor fluids (VI between 130 and 170), but at normal temperatures would be around 68. ATF is going to start out at half of that viscosity, with a VI around 35 cSt.

The equipment manual would be the best start, but you will probably find it looking for a MIL 5606 oil (aircraft hydraulic spec) that has about a 15 cSt viscosity and a 200+ VI (normally red), or for the least problems, the green fluid used for hydraulic suspension, MB folding tops, Chrysler, Porsche and other steering systems (electric-hydraulic systems), etc. It is about 15 cSt at 40C, but has a VI over 300. This lets it operate at a narrow viscosity range for best performance (as long as the system is designed for a low viscosity fluid.)

Here is a graph that compares it (green line) with various ATFs.

I have only owned and used BOSS snow plows, which seem to be the choice of most commercial operators here in the Upper Peninsula. The other brands typically found in our area are Western, Sno-Way, Fisher and Blizzard. My older BOSS plow was designed to use Dextron ATF or 10 wt hydraulic fluid. Most of the older Western units with the combination pump/lift cylinder also use this fluid. BOSS has more recently sold their oun brand of fluid that is lower viscosity (it looks like 0 wt ATF) for all of the newer hydraulics that are mounted outside on the plow itself.

Have your buddy find the owner's manual for the plow and check for the specified fluid. If that is not available let us know what brand of plow and a description. One of us might be able to recommend a common (and perhaps less expensive) fluid that will work properly.

I've been using ATF in my antique Fisher engine mount pump for years.

I've always used ATF in my plow (Meyers) but I've also thought it required way too much electrical juice; now I know why. Will switch to winter hydraulic oil and see how it goes. Great OT thread!

Plowing the driveway with a 57 Chevy is a pretty cool. Great use for a four door.
Our old shop plows were Meyer units and the fluid would take on moisture from the vent, the moisture would freeze or slush up when parked outside overnight, the blue fluid seemed to lessen the issue.
Anyone else have moisture freezing issues ?

Not on my rig and I bet UGLYTRUK has no moisure problems either. Both of us have the hydraulic units fitted under the hood where it stays warm and dry. Mine has an electric motor-driven hydraulic power pack whereas UGLYTRUK has a hydraulic pump mounted to and belt driven directly off his truck's engine.

The outside mounted hydraulic units are prone to this because, even if they get heavy use, they never really warm up the fluid enough to drive off any moisture. When they do cool off, moisture laden air gets drawn in and condenses, just like the gas tank on an unused car. This is why it is recommended that the fluid be drained and replaced yearly. I would speculate that the "blue" fluid might be glycol based, like brake fluid, and able to absorb a fair amount of moisture. If this were the case, it would be imperative to change it yearly.
