Snow Plowing Speed "Speed is Good"

Recommended Posts

pfrederi

Had about 6 inches of snow today so it was plow day no blowing required.  fired up the Charger 12 and went to work.  Didn't get much seat time only took a bout 35 minutes (see pics in the show me your snow machine thread).  Running up and down the drive way I have to plow to one side after the first pass at full throttle full speed...she rolled the snow off beautifully.  Now I know there are a lot of opinions about "best" plow tractors.  Gear drives  400 series 520's but to paraphrase Gordon Gekko (Wall street) SPEED is good.  I know most like Etons over Sunstrands but look at the top speed difference between a Charger and a 520. Now seat time is good but sometimes getting the job done and going inside for a hot toddy is better.  Besides it rolls the  snow over better .  Gear drives with their low top speed and slooow reverse are not in consideration. Also note the similarity in weight  (I always thought 520 were heavy...  )  When it comes to plowing horse power is not terribly relevant unless it can drive more speed traction is the limiting issue.

 

First pic is 520 second is Charger.12

 

Let the disagreements begin....:P

I always plow in 3rd gear high range when I know that there is nothing to hit. I agree that it rolls the snow off the blade better with speed. My GT 1600/8 speed ain’t to fast, since it’s a dedicated plow machine I have considered upping the drive pulley from 4” to 5”.

I too plow in 3rd gear high range. Driveways are long and paved so no worries. I don't know what my 312-8's speed would be.

I put this little beast In 2nd or 3rd gear and let it rip, it rolled the snow right off the plow.  Todays snowfall was mostly sleet and was a bit rough on the snow thrower.  To heavy. :auto-layrubber:

note the pic above 

 

manual trans speed 3rd gear / high range:  5.5 mph 

 

400 series hydro: 7 mph 

 


so I don't how / why a 520-H top speed is 5 mph - when a 400 hydro is 7 mph

I normally plow in second gear at about 3/4 throttle.

 

I'd go faster but our gravel drive is too rough and I'm not fond of forcefully removing the plow from tractor by that method.

 

Later in the season but before Mudd I can speed up a bit.

@tom2p     I  see the speeds are different than my 312, do you know what year that chart pertains to.

Didn't some government or ANSI standard kick in and limit top speeds about 1990?  I believe I read that years ago.

My 1991 Operators Manual  Quotes approximate Forward variable 0- to 5.6  and reverse   0-3.4      MPH     This is for a 520 - H. Don't quote me on this but I believe Kohlers were used on the 400 series in 1985   6   7  and newer were 16 h.p Onans but Someone with more knowledge on that question will chime in. This is off the top of my head and seems to diminish the older I get.

maybe the quickest and least expensive way to gain more speed is to pump up those rear tires 

 

way up  lol

I wonder what Frank’s overall top speed is?  10 hp, Sunstrand, big wheels and tires, stock pulley configuration!  Maybe with the hydraulic lift, I should put my plow on him for a couple rounds with the white stuff!

Is this the case ?

 

back in the late 70's / early 80's I had a summer job at a hydraulics and pneumatics distributor 

 

at that time Sundstrand was considered to be the best ; the 'Cadillac'

 

construction equipment (including a zillion cement trucks ; pump typically in the front of the rad and motor back near the drum )

 

underground mining equipment 

 

paving equipment (including the 'Roto Mill' milling machines)

 

heavy manufacturing equipment 

 

etc

@pfrederi

When plowing speed is definitely king. I found that to be absolutely correct while plowing my neighbors 1/4 mile driveway at a steep incline over the years. Used to plow it with his C series in third gear. Then started using my Electro to do it. Going up hill Electro is much faster rolling snow off plow much easier. Then going downhill I actually have to hold it back since it will go twice as fast as uphill. Downhill snow just literally flies off plow. I do it the same way as you do. First pass with plow to side full throttle and speed at center of driveway, then up and down on opposite sides so I don't have to turn blade. This thing is absolutely unstoppable. So many time guys driving by with plow trucks just stop and watch me plowing it giving me the thumbs up.
