When to use four wheel drive?

   / When to use four wheel drive? #181  
I drive several electronically shifted ag tractors with wet multi-disc clutches that engage the front axle;
they will bind and scuff in a tight turn, even with well matched up tires with just a small amount of lead in the fronts.

I was hoping this discussion could be used to educate owners/operators that might not understand the mechanics of simple linkage engaged 4wd/FWA. It has not. Sorry for the distraction.

Axlehub's Massey is simple linkage engaged 4wd/FWA. It binds and scuffs at certain positions when it's engaged. All tractors regardless of size with this system do. Not condemning them. It's just a simple truth.

The cleanest operating system is true 4wd. They are Center Pivot. No disengagement required. No binding/scuffing. Ever.
Richard, I appreciated the technical discussion and I am sure others have as well so...


I believe I stated earlier here, the answer to the OP really depends on the specific use/situation. Experience taught me quickly how I should employ, since I live on a steep slope with a subcompact with FEL and BH but also have tight spaces and asphalt driveway to negotiate. I'm sure many have learned here and hopefully the thread saved someone from getting hurt.

I only engage 4WD after I get stuck. Then I leave the tractor in 2WD and put my truck in 4 low while I try to extricate it from wherever it is I've managed to get it stuck this time. ;)

Thus my quest for a 4WD tractor...

Greggyy,

I think your question misses a key 3rd choice -

3. that part of tbn members - perceive a far different user mix than TBN has.

10 years ago there were far fewer scut owners on TBN - and today there are significantly more. But its not just the tractor size that makes the difference - but the reason they have the size they do. Scut owners are far more likely to have small acreage and use their units far differently than the more hobby or mid sized farm needs of prior TBN posters. That difference in land location and type is substantially varied from traditional hobby farm land. While I have a total of about 4 acres contiguous - I don't have more than 150 feet I can go on relatively flat land - everything else is slopes and sidehills and most are steep pitches. I have another 1 acre of lawn 2 miles away that is flat - but I certainly don't transport my scut there each week as it isn't worth the effort - and that is just lawn that gets cut with an aging lawn tractor.

So during normal seasons - my scut is either mowing or digging or log moving or hauling items on primarily hills where 4wd is absolutely needed. And in winter I'm plowing or snow removing on a large long steep concrete driveway and sidewalks - again in 4wd.

But I think there are a quantity of tbn posters who can't imagine that there are very many like me - and they still think in terms of 15 to 60 acres of land with much of it flat or near flat and a tractor in the mid to large compact sizing ranges.

As another example - my scut is certainly not awd - however I'm in 4wd (front wheel assist if you require the phrase) - but neither I or anyone else could tell on lawn or dirt or gravel - that my steering is altered in any way from 2wd. Only on dry concrete or dry blacktop can you "sense" a different sound in 4wd to 2wd - and in no way does it alter the turning ease and turning circle. Maybe larger compact tractors and older equipment is stiffer steering in 4wd compared to 2wd - but I've never ridden on any that are even though I know my neighbor's jd x728 lawn tractor is stiffer in 4wd.

My point greggyy, is that I think older or larger tractor owners assume alot about smaller tractor owners and believe those small unit owners have less awareness in their opinions - or maybe less skill in their decisions. My point is I think it is just the opposite too often - that larger tractor owners or land owners maybe don't recognize how much things have changed in tractor ownership in the last 6 to 8 years. If I had 30 acres and a Massey 1700 series unit instead of 4 acres and a Massey GC1715 - I'd have more flat land and easy rolling land to use 2wd for. I might have a lot of tilling to do or pasture land maintenance or rebuilding. The number of scut tractors and small frame compact tractors (like Kubota's B series etc.) are outselling percentage wise each year these last 6 or so years especially - and its because of their land locations and land sizes and because they are often in areas once were rolling farm land that now is subdivided for homes with 1 to several acres with far less flat land percentages and more hills and challenging landscapes and woods issues.

I live very close to many farms who would rarely need 4wd - but I live in areas right next to me that ALL need 4wd.

JMHO


I have a small block & I wont call it hilly, I would say in some parts, if you put a vehicle there, any type, it is going to become a major retrieval operation with cranes etc, even if you had 10WD :)

I find that I am in 4WD more often than I like, cause the lever is near my foot and I tend to engage it accidentally, I keep it off if I can, my pasture is very low atm and 4WD rips it when turning far more than I like, I basically do not need it for most chores. Actually more weight will be the probable answer when 1WD actually loses traction, cause I do do other things if it was that wet and muddy :)

Now there may be people using very light tractors with the wrong type of tyres etc, or maybe using them for something where they need 4WD all the time, but the posts I refer too, sort of sound like some do things just because they think it is better, or safe, or whatever...but seemingly not knowing why you may have it off, or on, it is something I guess you can sense, in any vehicle. Locking 4WD is not going to need to be on 100% of the time.

Of course, however, I do not know everything & I have no drama if people want to use 4WD all day every day, needed or not, knowing the diff or not, etc

So I use it when needed only, and I try and default to just Rear WD if my foot will comply and not sneak it into 4WD :)

Can’t think of one good reason except hard ground pavement not leave it in 4WD. You payed for it use it, can’t wear it out...

The difference between being safe rather than sorry is not always well defined...

descending a grade that does not normally require 4WD can turn into disaster faster than an operator can react...all it takes is running across a section of wet matted leaves and the rear wheels can break traction and all control is lost...a tractor in 4WD will prevent this from happening...
Knowing when a tractor needs to be in 2WD is obvious...not necessarily so at other times....

Some people will learn this the hard way...some may not survive to relate the lesson learned...!

Exactly!

This thread might make the 200 mark.....

Here, I'll help it along.

If you are in a situation where being in 2wd creates a scenario where control of the tractor is lost and you can't think thru a solution before disaster then you should NEVER take your tractor out of 4wd, even on pavement, you just never know......

I know I have chimed in on this thread more than my share. Richard, I think you nailed here. I do operate on a significant slope and have 'lost' it in 2wd... first because I was a rookie. I learned that day that loss of traction going down a hill is no fun and it is not controllable, and can be fatal. 2nd time, it was because 'I forgot' to engage. I don't want to experience a 3rd time. My habits changed.

I have learned to truly appreciate the operational tips here on TBN. The safety ones can seem a bit motherly, but I don't take them that way any more.

Some members have said what you said exactly too a few times..... What seems to be painted too me, is people using front loaders on light tractors who have experienced what can happen, or came very close too it, or have read about it and just say 4WD always and only, in fact that lever or knob for them should read sealed pavement or hard surface/loose surface. I wonder how many know why and understand exactly how the brakes work on the tractor they have.

Wonder what they did in the 50's and 60's was my thoughts last night. Must not have got much done.

it seems many will do things without full understanding of why & they may still be very close to the edge but think otherwise. Will concede, when I think of tractor, I think of heavy rear ended machine with chunky tyres, not a tarted up lawnmower with a bucket and lawn tyres smaller than my quad bike has.

It is all good by me if people use 4WD all the time, I can't find in my old Inters manual what I am supposed to do when using it :)
