7 1/2' plow is kind of small for a full size truck.
A 7 1/2' plow at full angle is only 78" ( 6 1/2 foot ) which puts it right at the width of most full size trucks tire path.
That is probably why you are running over your spill, you may be fine in a straight line, but as soon as you turn it isn't wide enough.
I personally believe 7 1/2' plows are better suited for mid size trucks and 8 footers should be on a full size vehicle.
9 footers on full size duallies.

 

But plowing driveways and bank stalls I can't use an 8ft plow its just to big.

 

Either a smaller truck, or what you have, is what you have.
My 8 foot Arctic at full angle is 84 inches ( 7 foot ).
You really can't back drag an angled plow, so if the 7 1/2' plow is all you can use, then it sounds like you are already set.
Either you'll have to do follow up passes to clean up, or get a smaller truck for the 7 1/2' plow.

2robinhood, why do you run in 4 low? all i ever run in is 4 high, unless i get stuck in 4 high, like i did the other day and 4 low came to the rescue. plowing in 4 low can be bad for your engine because it causes the engine to run at higher rpm's in slower speeds.

 

I'm not plowing for cash, so high speed isn't an issue.
With 35" tires and 20" of snow, 4 high will make my trans temp come on.
In 4 low, it keeps my light out.
I'm not blasting a shopping center parking lot, I am doing my and my families homes.
From place to place I am in 4 high.
I only go in low when I am pushing.

 

hmm, thats odd. i have an 800# plow hanging on the front of my truck. i dont have any engine, or trans overheating issues and i have larger than stock tires. i think you may have a transmission cooling, or cooling line problem. i often plow in 2wd too. i only do driveways and i dont do them fast i take my time because i care about my truck.

 

35 inch tires with 3:55 gears, may very well get the tranny hot to start with. Let alone plowing.

 

IMHO, i just wouldnt plow with a 1500.....thats just my .02 cents....many people may have not had problems, but if you dont know how to plow, your going to be replacing parts frequently in that front end. So all the money you make plowing you'll have to put back in the truck.....As well as needing a trans cooler, a deeper tranny pan wont hurt, and put in a mechanical guage so you can keep and eye on the temp....heat is the #1 killer of transmissions....

But its your truck. You can treat it however you want

 

my trans has roughly 13k miles on it, i installed an aux. trans cooler when i installed the trans, only thing i dont have is a gauge. i also load the bed up with about 700#'s or so to equal out the weight a bit, so the plow isnt as harsh on the front end. no matter how you look at it you are still going to be replacing wheel bearings, and ball joints frequently. it doesnt matter if its a 1500 or a 2500, they are still going to be needed to be replaced as often.

 

Why are you letting the snow get that deep? Its stupid!! I go out twice over 10" of snow.
