Tractor size and HP

[Kubotafan]

I heard or read that when buying a tractor that buying bigger didn't necessarily mean more power. For example, a L4060 may not seem to have more power than a L3560 because the L4060 is a bigger frame and heavier tractor. I was told that if buying a larger frame tractor you should get the most HP available in that size frame. For example the L4060 and the L4760 are the same frame size, so you should buy the L4760. Can anyone give help from experience.

Never heard such thing

No really heavier but yes if money is no object get the most hp in that size frame

Buying bigger usually means heavier and more traction for a given amount of HP. For example, I think the 32HP in my L3200 is a lot more usable due to the weight/traction than 29HP was in my B2920, even though the B2920 weighed about half as much. Per weight, the L3200 would seem underpowered compared to the B2920, but the weight makes it more of a workhorse for traction-dependent uses or ground-engaging tasks.

I've never regretted getting the M8540 V the M9540. Just buy more horsepower than you think you'll need if you can afford it. Weight and loader capacity would be what I'd be more concerned about. The hydrostatic transmissions seem to suck up a lot more power than a gear trans though.

I had a Kubota B3300SU (33-hp). Sold it to buy a Kubota L3560 (37-hp). Not much difference in horsepower but the L3560 has much more pulling power due to its weight.

That said, buy all the engine power and frame weight within your budget.

A lot depends on how you are using it. What tasks will you be doing that requires maximum power?

I also suspect that the use of the word "power" may be confusing. Is the issue traction? Or actual ground engaging traction? Or PTO power? It's different if you are pulling a 3 bottom plow vs. a bush hog. Or lifting with a loader. Or drilling post holes.

In some of the "pairs", it's the same engine (displacement), just apparently tuned a bit different.

I live on hillside land. Have owned several BXs, Bs and one L.
I owned a B7800 (31/32HP) 1700 lbs and traded it to a Grand L3240 HST (32HP) 3400/3700lbs. The HP was about the same but at the steepest point on my hillside the L was running out of steam so it didn't have more power. The B7800 never slowed with the same Landpride 6' rear finish mower on it going up the hill but the RFM would swing the B7800 around when I got to the bottom of the hill but it never steered the L.
Weight usually means more traction. Diesel HP is Diesel HP and I'm doubting a Kubota 32 HP in one tractor with more weight has more power than another Kubota 32 HP in a lower weight tractor. Kust call me a skeptic.
I also am not a believer that bigger is better, it's just bigger, unless there is a need for bigger. If there is a need for bigger then bigger is better but if there is a need for smaller then smaller is better. Everyone has different needs and requirements and any time someone, thinking of their own situation/experience/belief system/believer of other peoples needs, posts the bigger is better "theory as fact" brings forth those of us that have experienced the actual experience of going up and down in tractor size ownership and experience. We, us owners of several size tractors over several years, don't as a group believe that bigger itself makes it better but just makes it bigger. It compares to a 3500 series pickup truck is better than a 1500 series pickup truck. Yes the 3500 is bigger and maybe even stronger if it has more HP but if it doesn't have more HP then it isn't stronger. Remember the Ford Lightening pick up trucks with like 500/600 hp in the small truck? Stronger but not usable except for drag racing.
Match the tractor size and HP to the jobs that need to be done or as Tim the Toolman says, MORE POWER!!!:cool2:

I have noticed that and wonder what is added to make the price difference.

Well, yes, no and maybe...sure wish there was such a thing as "universal truths" when buying all tractors but I'm not sure there are many. I have run into a lot of "This" is better "if" and "that" is better "if"...

One thing is going to be more important for pulling and another for PTO and then some need both. You really have to decide what you are going to do to determine what you need as to frame size, weight and engine. There are guys on here who can write pages on this, discuss the right amount of tire slip etc. for the best traction and fuel efficiency, how to properly ballast your machine and so on.

JONTHOMAS put it pretty much like I would and I often use the "bigger is not always better..." myself.

I bought an L5740, but would have bought an L5240 if I had found one, I am happy with our M8540 though the M9540 is the same tractor except has ten more HP; didn't need it. We have tractors from 22 to 85 HP, SCUTs to UT/Ag and they all have their place.

I have a L3540 but sometimes wish I had more power for blowing snow, and to keep MPH more constant on the road on little hills. I don't need more size or weight. The next size up is the L4060 which is a bit heavier and a larger frame. Would I see more power at the PTO and better road speed, or would the tractor weight absorb the extra power? Would I have to go to the L4760 to see much difference? The tier 4 engines are supposed to give more power. Would a L3560 hold speed better and give more power at the PTO?

When trying to figure out what size is right it is best to look at the most work you will be doing and the time it takes. I try to shoot for 90% of the work duties not just the 5% or 10% which are a small part but still often important.
This past winter I've been using a BX1800 with cab and blower to clean my driveway of snow. I normally run in high range with roughly 3/4 throttle and it will take it all day without moaning or laboring until getting to the end of the runs where the snow is doubled up. The worst that I'd worked it was during a thaw and it was coming off the roof and was about two foot deep of slush. The first pass when it wasn't doubled up wasn't bad but as the second, third and forth passes had changed the snow to snow cone slush I thought about what a BX2660 would be like blowing as my ground speed was down to about 2mph.
So for ten minutes of snow blowing in the winter of slush, vs probably ten plus hours of use for snow removal a year would you really have to spend the extra three grand to get the driveway clean? Over ten year ownership it is less then a dollar a day to know that I have the most available horsepower in that weight class.

I don't think getting bigger tractor with more HP is going to solve the "slow down when going up a hill" problem. My little B26 (26 engine HP) only goes about 12 MPH but slows significantly going up a hill in High gear. My LS P7010 (70 Engine HP gear drive) will go 25+MPH but also slows going up a hill and may even require a downshift to H 3 if hill is really steep and long. But even in H 1 it will still go faster than my B26. The manufacturers seem to just gear everything up to go faster with more power. I will say that my LS will spin all 4 tires in M 1 at 1000 rpm idle and not stall so more HP is good if you can use it, however without traction more HP is useless. I have the rears loaded and it still spins all tires.

With my L4240 HSTC(which is a lower horse-power for it's frame size) I have never found it lacking in power for anything I have ever tried.I run in M and toggle up and down with the HST+ for all of my work.Very rarely use L range in the transmission and only use H on the road.

 

[michahicks]

I agree with the thought regarding how the tractor is going to be used? I was looking for compact dimensions due to limited storage area, but loader and mower performance were also very high on the list. The B7610 HST offered the compromise I thought I could live with. When it comes to ground engaging performance, the 4x4 easily made up for the lighter weight of the smaller tractor frame! This thing THINKS it's much bigger than it really is, turned out to be an excellent compromise.

I owned a L3240 w/ loader. Do to poor planning on my part I ended up selling it.

Between the time that I bought the tractor, and then sold it, my needs had changed.

When I did loader work I felt it was a good idea to carry a 800# counter weight. I also ran loaded tires and wheel weights to help with stability. After using it for a while I wasn't happy with the tractor, and wished it was larger or at least had more HP.

If the same tractor had been used for mowing, or tilling, or for lots of other uses other than mostly FEL work, I probably would have enjoyed it more.


It was a well built, good running machine, that just wasn't suited for what I was doing with it.

Apparently you are only measuring "stronger" in terms of drivetrain horsepower only? Your comparison is flawed.

A 1500 pickup isn't "strong enough" to tow our horse camper no matter how much horsepower, the rear would probably be sitting on the axle and the wheels/tires/suspension are not STRONG enough to support the weight of the camper. Believe me, even a 3/4ton wasn't "strong enough". Sure, it pulled it okay, but is wasn't safe.

Horsepower isn't the only measure of a tractor. Gear it down enough and a 20 hp tractor will pull a 15' batwing mower. But try going downhill and stopping or turning and you will have a disaster.

As already mentioned, a tractor should be matched to the current and foreseeable needs.
