The 790 is a superb, trouble free little tractor. "Dated" it may be, but do you want a tractor or a Cadillac? As far as the difficulty mounting and dismounting...that is too subjective for another to make that determination for you. Have you tried the "fit" of the 790, 990 or others yet? My machine is a 670 (lower horsepower earlier model...same sheet metal as the 790..virtually identical except for power rating) and I've a bum leg. However,I've no problem mounting or dismounting the machine. You really need to make your own call as far as ease of getting on and off.

Now, the 790 is only availible as a gear tractor. Altough I prefer gears, sometimes hydro would be nice (just not worth the extra $1500-$2000 to me). It really depends on your circumstances. If you do go gear, just make sure you get the dual stage clutch.

The 790 has 25 HP @ the PTO. This is enough to drive most implements that a non-agricultural owner would want or need.

You mention you have 22 acres but only mow a few. How much will you need to mow or bush hog?

Skidding timber might be an issue, however. The 790 weighs about 2300 pounds. This may not be heavy enough to maintain traction when pulling logs (easy answer though...cut down the length of the log(s)).

I think you'll like the 790. Overall, it's one of the best values on the market. There's no doubt it'll be my next tractor (so you don't think I'm pushing Deere too much...my first choice was a Kubota...just got a great deal on the 670).

15W-40 should be fine. Make sure you get oil rated for Diesel engines!!!!
But you'll need to know how much oil to put in. Are you going to the Deere dealer for the oil filter? They should be able to tell you the capacity.

I've got the 3PH mower too.
There is a hassle when moving in close proximaty to anything (house,fence,trees, etc.).
My tractor came with the mower as part of the deal (it was a used machine). If I bought new, I'd give consideration to the MMM. But they are more expensive and dedicated to one brand of tractor. Obviously, you can hook the 3PH mover to any type tractor.
I also like the MMM since it adds weight LOW..just where you want it. Theoretically, it should lower the center of gravity...a 3PH mower won't..or not as much, anyway (once your tractor rolls, the 3PH mower would likely roll with it).
For me to add a MMM, I'd have to buy another tractor. It would cost too much to add the components to run the MMM.
The bagging thing is a good point. I wish I could do that. My next tractor may be set up so I can (tow behind units add too much length).

According to Machinerylink.com, fair condition should be priced at $4800, premium condition $5900.
This assumes a MFWD model.
If two wheel drive, prices should be $500 less.

This doesn't include the mower deck. Add a few hundred (no more then $300 or $400 for that.

"checked the pricing; it looks like a 4110 would push past the $18K mark pretty quickly when you add the FEL and the 60" deck. What is your thought on this? Is the 4110 worth nearly twice what I might get the 755 for?"

No...not unless you really want to spend the extra money.
The 755 will do you fine...

I think the JD 790 uses a model 70 loader, but you'll have to ask the dealer to confirm this.

I don't know about the model 60.

Might be cheaper to look for a machine that already has a loader.

I run gears on a Deere 670. Since one doesn't really shift that much while operating (except for loader work), gears are fine with me.
Once you get operating, you don't need to look at the shifting when you do it...just as you don't look at the shift lever when you're changing gears in a car or truck.

Now, the biggest downside in my particular case is the single stage clutch. This means when one depresses the clutch, the PTO driven implement stops too. Well, one does learn to live with this limitation, but my next tractor will have a dual stage clutch or an independent PTO.
As far as loader work...basically just shift between a forward gear and reverse...not that tough.
I think HST is great, but I don't think I'd pay the extra $1500 to $2000 for it.

"Is Deere still making this model? or is this left over from before the days of the 4000 series?"

Per the Deere website and the local dealer, the 790 is being built currently, along with the 4xxx series machines.

Seeing as New Holland just started building an equivalent machine (TC30), looks like the 790 is a competitive model.

My dealer says they sell fairly well...

"The first time my Kubota overheated from a clogged grill I looked around to see who was honking at me. There was nobody for miles around, I thought I was hearing things.

My boat does the same thing...the horn honks if it overheats. Very weird."

Well, might be weird, but it saved your engine...and a lot of money.
I take it your Kubota and boat don't have temperature gages?

"And I never thought of Roy Jackson's point about keeping the tires at high pressure during winter storage to avoid flat spots..."

I used to own a Porsche (and, over the years..several other sports cars) which was stored every winter. The tires were good performers....real sticky in the curves and sweepers.

The problem with performance tires is that they are a softer compound. They wear faster then a standard tire you'd put on your minivan.
Also, they develop flat spots quicker when sitting.
Now, if I didn't overinflate, it was like driving on square tires for the first hundred miles or so.

I'd be really curious to know how the magnesium is mixed in with the water. I wasn't aware that magnesium is even water soluble.
I do know that it's pretty easy to light off as a powder or dust...burns quite hot, too.

I bought a John Deere 670. There is a picture of my machine in the CTB Picture page (see the photo link at top of the page).

My first choice was a BX2200 due to it's low center of gravity. This machine, including FEL, HST and MMM would have cost just under $13000. The 7500 and 2410 were about $1000 � $200 above the prices you quoted equpted as the BX2200 was.

However, a friend of mine took me to a John Deere dealer he'd purchased a machine from several years earlier (still dealt with them for parts, etc.). He'd seen this very clean 1991 Model 670 FWD tractor setting in the used equipment section of the lot.

We checked the machine out...I drove it (which doesn't prove much, just driving on the dealer's lot). However, it is a very nice machine...included FEL and a Befco 5' finishing mower (less then a year old). There were 600 hours on the clock. The price was $8500. The price included new front tires (couple of gouges in the side walls) and a service.

Since this was considerably less then the Kubota's (although they were new machines), the dealer has an excellent reputation for customer service and both my friend gave the dealer such a great reccomendation...well, that's the machine I bought.

The 670 is a gear tractor with a SINGLE STAGE CLUTCH...no problem with the gears BUT if I had it to do over again, I'd of purchased a tractor with a dual stage clutch...maybe HST, but definitely at least a dual stage clutch.

The Kubota's are somewhat lower then the Deere's. I like that lower C of G...when yr setting 4' off the ground, that little slope seems mighty steep!

As far as Horsepower, Kubota advertises gross HP, Deere advertises net HP. Net will be lower then gross, but a more realistic number for real world usage (I'm not slamming anyone's marketing, so don't flame me!). The 670 is equivalent to the 7500 in power, by the way.

I'm not particularly driven by a make. I would not buy a grey market or one of the lesser known brands (mostly due to the service and parts availability issues). There weren't too many used Kubota's around (some mid 80's 6100's).

So, I ended up with a Deere.

I tell ya one thing...the 2XXX series Kubota's are real winners IMHO (as is the 7500).
I also think the BX1800, BX2200 and BX22 machines will sell like hotcakes due to their power, versatility and SIZE (not to big to intimidate wifey from driving it. The loader capacity is quite adequate for the great majority of residential users.
If it wasn't for an area I've got to bush hog, the BX series would be the optimal tractor for me. That's the only area I think the size of the BX series works against it (for residential use). Also why I priced the 7500/2400.

But, I think my Deere is a fine machine...very capable for my usage.

As long as you stay off pavement, you'll be OK (now, driving across a 2 lane road wouldn't hurt either...don't drive down the road though).

However, why stay in 4WD? It's just a quick lever movement to put the tractor in or out of FWD.

Normand,
The pattern is a four speed with reverse. There is a high-low range selector lever. Select Low Range and the gears are 1 through 4, select High range and the gears are 5 through 8 (as shown in the JD Manual).

You can start in any gear...you can start moving as easily in 8th as you can in first. As Mark wrote in his post, you don't shift up through the gears to accelerate. You select the gear that best suits the work you're doing.
For example, if you're going to drive the tractor from one site to another over a paved road, you'd probably select 8th gear (Range Selector in High, Gear Shift in 4th) and let the clutch out. This equates to about 11.5 MPH with the small Deere.

If you're working, mowing for example, you may select Low Range, 3rd gear. A mower has to run at rated PTO speed (540 RPM which is at 2500-2600 engine RPM). The speed is set with a throttle lever and is constant. The selected gear determines the velocity of the tractor. You don't use a foot accelerator (you can, but it would be hard to maintain a constant PTO RPM).

Driving the tractor on the road..well, then using the throttle lever or the foot throttle is really your choice. I normally set the throttle (when driving on a road) at around 2000 RPM and use the foot throttle to increase RPM (hence, velocity) as required.

Re: Tires

Mark, did you replace your tires with Turfs or Bar Turfs or Industrials?

Becky, if your going to replace yours, you might want to consider Bar Turfs over standard turf.

The Bar Turfs are on the rear in the linked picture.

God! This goes back many years!!!

Prior to synchronized gears, there were non-synchroed gearboxes (manual tranny's, of course).

To shift without crunching gears, one had to "doubleclutch" during shifts to a higher (or lower) gear.

The process was:
1)Clutch
2)Shift into Neutral momentarilly
3)Clutch
4)Shift to the next (higher or lower) gear

It sounds cumbersome, but with practice, one could do it quite quickly and smoothly. Or, so I am told...this is before my time!

Tell ya the truth, I only doubleclutched in one vehicle, an early '50' International 1 ton truck. Doubleclutching was apparently common (especially on Hotrods and sportscars) up to the advent of synchroed tranmissions, although I believe it is still used on big trucks (18 Wheelers).

My tractor is a gear tranny (1990 JD 670). I do not have to doubleclutch when shifting...maybe when going into Reverse..if I do it, I don't even think about it.
