4wd high or 4wd low

Im just curious, I spoke with an old salt that has been running old equipment but with little maintenance done to his rig. He claims that he runs in 4wd Low more often than not. Now, I know he is not setting any land speed records by doing that nor is he knocking out a boat load of accounts if he is operating at a snails pace. However, he claims he has yet to have a tranny problem or any major welds break on the plow. He does a great job with what he does do. With that said I was wondering how many people operate in 4 high and or in Low. Also, does anyone watch there Tranny temps when they plow? Not the Idiot gauge but actual temp monitors. I guess if you have the aftermarket gauges to do so.

hmmm.... I wonder how he gets away with it. He must be on uneven and slick surfaces the whole time. Most of the time, If the roads are fine to travel I'm in RWD. When the roads are still bad, it may call for 4 high. When I get to an account I will open up a lane and start in 4 high if that is what I was in on the road. Then, once I have a place to get a footing, I pop it back into RWD. If your tires are on dry pavement _or mildly wet or less.... NEVER be in 4WD period. Four low is the best way to mess some drive components up and start overheating things (tranny). ALWAYS watch your gauges. In every car you ever operate, because it may save your life some day. I never go anywhere without making sure my car isn't overheating. I watch it more on a plow rig. I have to replace my CV's and some basic wear and tear on my 2001 k1500 Z71 but it is the first time since it was new (and im at 81K on it). So in all, it was not bad. I don't even know when to use 4 low.... I have only used it once... and that was to pull a half full diesel fill tank that was bolted to a steel plate off of the ground at my facility to sell. That was really the only time I've ever used it in 81K miles. I'm afraid of breaking front end parts in 4 low when I get stuck (which has been a couple times only). So I just try 4 hi... then RWD then I rock it once or twice after putting traction aid down. If that didn't help then I call for a pull with my tow rope... not worth being impatient and breaking something... and I hate to rock it cause the tranny so I try to avoid that too.

IDK are there any 4WD component experts cruising? All I know is my experience since 2007 doing this.

i allways plow in 4low. otherwise the truck is locked in 4high from october to april. after my last tranny rebuild the guy doing it said try running in 4low. 9 years later no issue with the tranny (knock on wood)

i cant get out of my driveway in 2wd, so thats not even an option, def could not plow in 2wd thats just a joke. even with weight.

Nothing but misinformation in this post. 4 low will keep your trans temps down. You'd better do some research before you make a post like that.

Yep, Basher last year schooled a bunch of guys on that fact.
The idea behind why 4 low is bad for the tranny may not have been correct but I do know that guys engaging 4 low often have drive train issues. That is just what I've seen around here. All of the guys I know knocking into the low range break crap. I said IDK why, but it happens. I'm not a pro mechanic or anything. All I know is that 2wd should be used as often as possible and 4high after that... It may be a speed thing that the old timers were trying to teach me, but they say four low is a big no-no (and they have been doing it for 20+ years with success)

anywhere you can plow all winter in 2wd is a place that doesn't get a lot of snow, come to upstate NY(past Albany) and you will last about one maybe two storms with a 2wd truck. Most of the time I am in 4 hi but every once in a while 4 low is needed.

I'm in downstate ny orange county and just had an issue plowing a downhill tight garage ended driveway with 1 place to pile in the right corner the left side is all stone wall and 2 walkways and as it is I'm piling in the corner because the right side is some sketchy ass hill that both is high blocking piles until the end (driveway is about a truck and half wide 2 truck lengths downhill) anyway so I'm piling in the only available space which is a walkway to the back...and I got stuck on some weird landscaping which mind you there was 8" before I did my pass because it came down so fast and she was chatting my ear off getting contract signed...

so basically I was thinking hey I wonder if I had put it in 4lo instead of 4hi I woulda had an easier time plowing that. I mean I couldn't friggin CONCEIVE how I could even get into her driveway in 2wd i mean i need tires but damn people if you're not in the northeast i don't think you get 4hi and low are a necessary evil. It comes down hard and fast and you can't "get a spot for traction" because in storms like this (which are frequent, I mean they call them noreasters for a reason) the snow is covering what you just cleared within minutes! It can be crazy it was rush hour last night and everyone from the city commuting home and I mean EVERYONE was either stuck on hills or stuck because of the people stuck on the hills...
It was the worst I've seen and I know I'm new but damn dozens of cars even trucks abounded in ditches cocked across the road in spots... took me 4 hours to get back 10 miles home! I heard that my is getting a new weather alert for winter because of just how bad it was.

Anyway this is getting lengthy my point is guys worry about yourselves before your trucks or you could get hurt get in a jam or just I dont anything can happen and you gotta put yourself first truck second you're going to have breakdowns like budget for that don't fear it it just makes you plow scared and f****n' plow men and I bet women should not be scared we save lives sometimes with blocked homes we shouldn't plow scared

Beg to differ. Equipment and operator has mulch to do with it.

i've never broken anything drivetrain wise. so i dont see where using 4low is going to cause any damage what so ever. other then saving your tranny from high temps.

My buddy twisted his front drive shaft and it snapped plowing in 4-low. Plus you spin alot easier in 4-low. I always plow in 4-high.

it all depends on your truck, your location..ect but over the last 8-9 years, same truck, same locations i've used 4low for every storm. have not had a tranny issue since i started doing that and no drivetrain breaks. i stay ontop of maint and check everything often.

Can you explain how 4 lo would make any difference in snapping drive shafts?

It puts alot more torque on the drive shaft.

I have both 4wd and 2wd trucks and id rather be in 4wd anyday. I do agree that operator has alot to do with it, but having that option of locking the truck into 4wd is well worth it. Ive had alot of people tell me to plow in 4low, but i will agree its a snails pace and if your trying to get businesses open in the morning you better be working fast. I think we are spliting hairs here, but how long do plow trucks really last. There being operated in the coldest temperatures and being asked to do things that most vechicles are not. Just plow in what ever drive your most comfortable in. I just know in my opinion if its not a flat lot my rig is in 4wd and my 2wd truck is in the garage just incase I need a backup.

iv seen you post around that all you do is a your driveway and a few others so id agree with you with the 4lo is best for you and id say id do the same if doing driveways. the OP posted in the Commercial Snow Removal thread so lets assume hes not doing driveways and say that 4he is in bigs lots 4lo is useless most would use 4hi to break the first pass then 2wd. The place i plow is a big lot with a ton of islands to steer in and out of because of all the steering i stay on 2wd 95% of the time because if not when doing all the steering the truck will hop at times and thats just asking 2 break something and this has been for the past 4 years in the same lot so yes i plow a lotta snow in 2wd f250 diesel with about 1200 lbs in the bed.

true i do mostly 7-10 drives a storm, and i'm not tryin to rush thorugh. but thats 10 years of it on the same truck/plow so you'd think if there was any ill effect it would have shown up? i also somtimes plow our road which is 1/2 a mile long. i also do this in 4low but in 3rd gear as to get some speed up to throw the snow off to the side. now none of my drives or my road can be done in 2wd. ofcourse every person is going to encounter different plowing situations.

you are also running more of a bulldozer with your wings, that could very well be why you can not run 2wd, but to each his own as long as were all making $$$$$$ its all good

4lo or 4hi

Hi all
about the 4 hi or 4 lo debate The best thing to do is try each one and see which works best for what your doing.

If time isn't an issue, where you gotta get from one driveway to another as quickly as possable then 4 low usually works good. You take it nice and easy, it's easyer on the drivetrain and the plow. BUT if your doing roads 4 lo just won't cut it. Some times you may find that a combination of the two is what you need. As far as using 2WD or 4WD, again it's what works best for what your doing. So go out play, have fun, and see what works for you.
