Hello All,

After many years with many different brands of riding mowers, the time has finally come to own my first JD Green Machine : )

Been nursing an older Craftsman unit for many years now, while being on the lookout for anything from 318's to X350's. (even some LT/GT and basically anything in the line with HP lol)

Came close on a few auction units, but very hard to have confidence not knowing service record and they all went high in the end. (higher than what I was willing to risk anyway)

Anyway, lo and behold my good friend and neighbor is cleaning house the other day and getting rid of a bunch of his fleet. Not even on the radar of what I'm looking for, but he uncovers a 2011 D100 with 150 hrs on it and I know he maintains his stuff to the letter.

Thought about it for a day or so and was going to pass, but then decided that, even if just a bridge for now, significant upgrade from what I'm driving. So I pulled the trigger and drove her down the street and parked in back storage bldg.

Decided to join a forum for some helpful tips and info, and to ask some Q's along the way.

Who knows, maybe even Narrow down my ultimate search for what I'm looking for as well.

My end rig would be a mower/ hauler (small trailer) and blow snow in the winter. Doesn't have to be Crazy, as I have a neighbor with Big tractor blowing rig for Serious storms. So 5-700 series def out.

Biggest consideration, the older "built like Real tractors" models, vs the newer "more creature comfort" models.

Was dead set on a 318 for years, but recently and having driven several models, am leaning towards one of the newer gen models. any opinions and info more than welcome. I know debates will always Rage over which is best, but to me the more opinions and info the better!

On the D100 now. Have only owned it for a day, lol, but already the wheels are turning. Originally figured just use as lawn mower because only 17.5hp. After searching around, seems if done right, more than capable of blowing snow ect.

So biggest question I have is compatibility with other models I may be interested in.

If I set-up a snowblower on this D100, what other models will it also work on if I upgrade?

If I build a hard cab enclosure, will it work on an upgraded model I might buy in the future ect?

Since new the previous owner has just done oil changes, lube, replaced drive belt once, air filter ect. So zero major issues. (knock on wood)

I'm aware of the cam drive comp relief issue with these engines, but am a competent mechanic, so really not too concerned.

Something of interest that somewhat weighed into my buying such a low entry model, other than the deal just being too good to pass up;

Another neighbor has a D130, not sure of hrs but thought it was 200ish. blew out the side of the block last year. This got me to thinking (D130 22HP? I think) looking at that engine, looks identical to the 17.5hp in the D100. So where is the extra CC's coming from? (haven't looked up specs yet) Most likely a combo of bigger piston and more throw on crank, but possibly just bigger piston. Or possibly just stroked crank?

If stroked crank only, disregard my thought process, but if larger bore for bigger piston, makes me think thinner wall = weaker block the larger they went and maybe then the 17.5hp is the better choice for single cyl model?

Just did some spec searching and says D130 should be V-twin? Going to have to take another look, but could swear the engine I looked at had same vale cover in front just like the 17.5hp in the D100.

I ran a 430 for years. They were hand hydro control, like the 318.
Imho, once you use a foot controlled hydro, you'll never want to go back.
(doesn't apply to the gear drive D100, but does apply to 318...and other hydro's of that vintage, if you're still haunting auctions and watching 'for sales')


D100 is gear drive and single cylinder
D110 and up are hydro -- but the hydro used changes with 'higher' model numbers
D120 is a larger single cylinder
D130 and up are twins
D130, D140 and D150 are 40 cu inch
D160 and D170 are 44.2 cu inch

If you have a small yard that is mostly level and flat and want an inexpensive mower, the 100 series machines can be a good choice. But, if you spend more than a little time here you will likely be convinced that you need more a LOT more. Perhaps you will decide you really can't live without diesel and AWD. Or perhaps you will be satisfied with "just" a garden tractor.

Craftsman used to make a range of machines. They were all built to a (low) price point, but some were actually very good machines from what I have heard (and could be called actual garden tractors). The rest would be lumped into the cheap box store machines that are designed to last no more than a decade and not very capable.

Some people have had good experiences with the D100 series machines, but a lot of people expect to get garden tractor performance/capabilities for a box store lawnmower price. They are usually dissatisfied and angry at Deere for "building junk".

Thanks for the detailed post! Reading through it, I'm thinking it has to be a D120, not D130. As the D120 has same single cyl engine, and they did increase displacement by pretty much stuffing a larger piston in there.

Bit of searching and easy to find D120 windowed blocks, so guessing it's a common theme? Although from broken rods, so did they find the limit of the rod by slapping a larger piston on it?

Sorry, I'm not a follower of what's happening with the briggs single cylinders engines deere uses in the smaller models.

Over the years I phased out all the briggs single cylinder stuff and replaced them with Honda's.
Did have many many hours of good service from an 18hp Briggs Vtwin in an 'off-brand' mower. The rest of it fell apart but the vtwin was problem free.
It was replaced with a used 430 w/60". Reduced the mow time from about 6 hrs to about 4 hrs.

If you have a small yard that is mostly level and flat and want an inexpensive mower, the 100 series machines can be a good choice. But, if you spend more than a little time here you will likely be convinced that you need more a LOT more. Perhaps you will decide you really can't live without diesel and AWD. Or perhaps you will be satisfied with "just" a garden tractor.

Craftsman used to make a range of machines. They were all built to a (low) price point, but some were actually very good machines from what I have heard (and could be called actual garden tractors). The rest would be lumped into the cheap box store machines that are designed to last no more than a decade and not very capable.

Some people have had good experiences with the D100 series machines, but a lot of people expect to get garden tractor performance/capabilities for a box store lawnmower price. They are usually dissatisfied and angry at Deere for "building junk".
The D100 just fell into my lap and couldn't say no. For the past cpl years I've needed an upgrade and it is surely that for now.

So thinking of it as a bridge to get me to the set-up I'm really looking for, then easy retirement at our family cabin where many have talked about a rider down there. (less than 1/2 acre but biggest is large blvd so prob makes sense)

Our property is just about an acre, so nothing huge, but not tiny either. Mostly flat land with a few slopping ditches.

I am a Diesel fan, having a few 1st gen Dodge Cummins and even bid on a 332? in one of the auctions about a year ago. Over 2k hrs and tractor only, I think it went 4200? (plus taxes, buyer premium ect)

Not too familiar with which models came diesel and how many choices, but not sure I need that heavy of a piece of equipment.

10 years ago I would be looking for an older model and prob restore the thing while I had it. (always ends up that way) and I think most I bid on at auction where aimed in that direction.

After riding around on just the D100, it is So much more comfortable to drive than any other rider I've owned that I'm thinking reliability and creature comforts over owning a piece of history that I spends countless hrs restoring to mint.

Probably start with engine power and reliability, then best hydro reliability, then see what that leads to without going crazy. Have considered an X350 and actually leaning in that direction, but remaining open, specially with the D100 buying me a little time now.

Engine power is likely the last thing you need to worry about, but the first thing they sell you on. It takes much less horsepower than you might think and they also play games with horsepower specs.

Engine reliability is important, but if you focus on transaxle FIRST, the engine will likely be fine as long as you stay away from the well known issues on certain years of certain machines.

The transaxle and frame are things that really matter, but are harder to sell. The X350 is great except that it has the K46. I have had good luck with the one in my X300, but others have not had such a good experience. My X534 kas the K72. It is WAY more capable and it has diff-lock. I bought it for the diff-lock. It doesn't cut any better than the X300, but it does everything else better and is more comfortable. I just use it for mowing. I do have some significant slope that it handles just fine.

I also have an X749. It is in a completely different class. I think it is too big for mowing my property, but great at being a baby tractor. I have a CUT for my real tractor needs.

It has taken me 15 years to figure out what I need and that no one machine can do it all. Your needs are likely different, so spend some time figuring them out. But, resist the temptation to get one machine to do them ALL. If you do, it likely won't do the thing you need done the most very well, and unless your needs are fairly limited won't be able to really do them all.

When talking about transaxle strength and reliability, I'm guessing your talking hydro trannies?

Even my little 12hp Craftsman can tow cars around the yard, being a standard gear box.

So hydro = User friendly at the cost of durability and reliability

While the standard gear box = row gears but do just about anything you want

Interesting,,,,,,

It has been a LONG time since a gear transaxle was on anything but the most basic lawn or garden tractor.

Hydros have been common for decades. You will find bigger tractors with fully gear transmissions. But, you are in the lawn and garden section not the big tractor section.

Tow a car on level ground is not hard. One person can push a car easily. That is presumably less than one horsepower 😉.

You will get better advice if you provide more details about what your property is like and what tasks you want to do with the machine.

The D100 is a very basic machine designed to be built to an inexpensive price point to compete with similar models from other manufacturers that have lower cost structures. It is fine for what it is intended, but it is unlikely to be a machine that lasts 30 years or, unlike some of the more expensive models that have better everything. They also cost 3 to 10 times as much.

My post was in response to some of the stuff I've been reading on lower end hydro JD's that owners say they can't even haul around a small cart for cleaning up brush, or have transaxle failures from just mowing hilly terrain on property. If this is true, I would take the gear box low end over any of those models.

Yeah, cars roll easy enough, but point is they are still 3000lbs and most of the stuff I'm reading, people are struggling pulling 3-500lbs!

Pretty sure everything I'm gauging towards I've already posted as far as land and what I'm planning to do. Just doing a little research now, and when I do that and come across stuff like this, I can't help but post my true opinion about it ; )

I think you're oversimplifying the differences.

Gearboxes / gearsets / transmissions come in many different sizes - just as hydrostatic sets come in many different sizes.

Overworking gear drives/gearboxes can kill them too.

Either of them will survive short periods of high loading -- like say towing cars in the yard.

Generally, it's matching the machine to the job it's designed to do.
Matching the machine to the 'duty cycle'

I'd suggest that the trade-off between gear drive and hydrostat (give that they are both sized correctly for the job they are to do) is convenience vs energy efficiency.
Hydro's create a lot more waste heat than gear drive.

That trade-off is can be balanced by the ease/efficiency of getting the job done. If the job requires many forward/reverse changes and/or if the job requires many different ground speeds -- the hydro is likely to outperform.

Following this advise, I have found that going to a 5 lug diff seems to put one is the "safer" zone when making a choice.

Having found this, I was thinking a K70 or 71 would prob suit me fine, but seeing that the K91 came in smaller models then I would have expected, It could be that I'm looking for one of the smaller offerings with K91 transaxle

Agreed, def over simplifying, but I tend to follow the "KISS" mentality and have a bad habit of thinking out loud. : )

To expand slightly on where it relates to me presently;

If the base model JD I just bought was a low end hydro, I most likely would not consider mounting a snow blower on it for next winter.

Being the most base model manual however, I have every confidence that it will handle a snow blower fine, as long as it's chained and weighted accordingly.

This is just from reading others experiences though, so I could be off base?

What "smaller" tractor do you know of that has a k91?

All the k91 tractors I know of thru the years are all roughly the same size and weight.

K91 or 92 = x7 class or it's grandparents

It is as simple or complex as you want to make it. Every machine has some work load for which it will have a short lifespan. Every machine has some tasks for which it is good or better and others for which it is not the best choice (could be for many/multiple different reasons).

My comment about transaxle was understand what the manufacturer of the transaxle recommends as appropriate usage. If that is consistent with what you need, you will probably have a good experience. You can get as detailed in this evaluation as you want, or you can keep it simple (cheap - mowing flat areas only, middle - ground engagement, expensive - lots of great capabilities). I have all three, X300(K46), X534(K72), X749(K9x). The first digit of the numbers gives an indication of the capabilities. Understand that the 9 is in relation to the garden tractor class. Compared to the (general) tractor class, it would be much lower.

You can spend hours/days/months/years/decades "researching" the differences in machines and their components. I know I have. But, it all comes back to what do you want to do with the machine, how frequently, how much, how often, how long, and how long you expect the machine to last. Many people say they want a machine to do everything, last forever, and be really cheap. That probably won't happen.

Was thinking 425-445, and since I was considering 300 series, didn't sound too much bigger, but I'm fairly new to this, so is that where the spit is size wise? Between 300 and then 400 = same as x7?

The D100 gear drive is probably stronger than the hydro T40/K46/K57. The T40, K46 and K57 are the hydrostats I would avoid like the plague. A K58 would be the minimum of what I would consider a good hydro for light duty longevity. Also a very important thing is to keep the fluid and filters changed. I also always soak new filters with fresh oil before install.

The K66 seems to be a good meduim duty hydro and the K70, K71 and K72 are great hydros for medium duty longevity. The K90/K91 are shaft driven heavy duty hydros and IMO the garden tractors with the K90/K91 don't make the best lawn mowing machines but they are very capable of tractor duty chores. Don't shoot me, it's just my opinion. They are just so big and bulky.

If you are looking at the X300 series just go ahead and get a X500 series. If you ask me there is really no downside other than price.

If you are just mowing grass on a mostly flat lot and running a snow blower the K58 is fine. If you have slopes or hills mowing or want to use a snow blade I would suggest the K66 as the minimum and preferably use a K70/K71/K72

The biggest thing with a hydrostat transmission is to get a heavier duty unit than what you think you need and don't work them harder than you need to. Also keep the fluids and filters changed and they will last thousands of hours.

The 425, 445, 455 are probably the smallest with the K9x. They are about an inch smaller in width than the X758. So, yeah they are all about the same size.

The X534 is an inch or two smaller in width, but longer.

The difference is the X758 is a few inches taller and feels bigger. But, not a lot of difference in size. Even the SCUTs aren't a lot bigger. When you get to CUT size, it makes a significant difference.
