3320 vs 4005 Longevity

When all else fails, read the manual...



Operating the Collar Shift Transmission

The machine may be operated in any gear with engine speeds between 925 rpm and 2920 rated engine rpm. Within these limits, the engine can be placed under varying load operations.

IMPORTANT: Avoid damage! To prevent transmission damage:
Depress clutch pedal and stop machine motion completely before shifting the range shift lever.
While operating machine, always depress clutch pedal and stop machine motion before changing travel gears.
Never rest a foot on the clutch pedal while machine is in motion. ​

Gear shift lever (A) provides three forward speeds: 1, 2, and 3, N (neutral), and one reverse speed, R. Forward speeds may be changed while tractor is in motion if clutch pedal is depressed. Stop tractor and depress clutch before changing direction.

Range shift lever (B) provides three speed ranges: A, B, and C, and N (neutral). Use decal (C) on the left fender as a guide. Tractor should be stopped and clutch depressed before changing speed ranges.
Using both the transmission gear and range shift levers in different combinations, nine forward and three reverse speeds can be achieved.
The gear shift lever must be in NEUTRAL for the engine to start.
1. Depress and hold down clutch pedal and stop machine motion before attempting to shift range shift lever.
2. Place gear shift lever in the N (neutral) position.
3. Choose A, B, or C speed range on range shift lever to match work application:
A High power/low speed operations such as tilling hard soil, mowing high grass, positioning backhoe, etc.
B Operations including moderate tilling, hauling, and grass mowing.
C High speed operations such as transport and light mowing.

IMPORTANT: Avoid damage! Never overload the engine. Select the proper gear and engine speed for the job:
For light load operation, use higher gear and lower engine speed.
For heavy load, use lower gear and higher engine speed. ​

4. Choose a gear on gear shift lever that matches the immediate power/speed requirements:
1st Gear High power, low speed operations.
2nd Gear Medium power, moderate speed operations.
3rd Gear Low power, high speed operations.
Reverse Backing up and positioning operations.
5. Raise engine speed to match expected loads. If a slight increase in engine rpm occurs simultaneously with moving hand throttle lever forward, the engine is not overloaded.

IMPORTANT: Avoid damage! Never rest a foot on the clutch pedal while driving the machine. ​

6. Release clutch pedal gradually to take up load smoothly.

So, the transmission is synchronized, at least in the foward gears

While I'm a true believer in the KISS formula (keep it simple stupid!") I would cast my vote for the 3320. Yes its less horsepower, yes it weighs a bit less, but I think these hydro tractors today are bullet proof. I bought mine new, it just turned 800 hours and its done a lot of work-only issues? Mice chewed some wiring that kept triggering fault messages and I wrapped some bailing twine around a front hub that eventually led to a seal failure.

I take care of about a 500 ft gravel drive, burn wood (hence its in the woods a lot pulling logs) some mowing-rear mount- and a lot of time at the fairgrounds running a Harley rake, York rake etc. Plus my two kids "borrow" it a lot-(don't buy a trailer!).

If loader work will be your primary duty, no question in my mind that the 3320 would work out best in the long run. IMO

I own a 3120 and love it overall. The ergonomics, hydro trans and overall feel, ride and features are great. It has some nice bells and whistles that the basic 4005 does not have. If all you did was disking or shredding in an open field, you might go with the geared 4005, otherwise it is a no brainer. I had a shuttle shift and a geared trans tractors before my 3120 and I cannot see going backwards with technology. The 3320 gets my vote for sure.

My info shows AKfish to be correct. Roy, what manual is that out of - 'cause it doesn't agree with what I have...

Three-range collar-shift transmission for quick and easy direction changes
Three-range transmission
The tractor has a collar-shift transmission with a three-range collar shift.
Nine forward and three reverse speeds
Key features include:
Straight-line shuttle shifting from forward to reverse for quick and easy direction changes
Well-spaced speeds for turf, loader, utility, and transport work
Neutral start switch prevents tractor start up when transmission is not in neutral

Here is the info on the 9/3 SyncShuttle trans - note that the 9/3 in the 4005 is not called a SyncShuttle...

The SyncShuttle transmission has nine forward and three reverse speeds and is perfect for operators needing a durable basic transmission to do a mix of field work and light loader work. The transmission is available on tractors equipped with the mechanical front-wheel drive (MFWD) front axle.

Two platform-mounted levers offer easy and comfortable shift operation for a pleasant operator experience. The gear-shift lever is easy to reach on the operator's right-hand side. The less-used range lever is located on the operator's left-hand side.

The gear lever selects one of three forward gears, one reverse gear, and the integrated park position. The range lever selects collar-shift A, B, and C ranges. Operators can easily select speeds or switch directions without having to completely stop the tractor with synchronized, in-line, shuttle-shift capability between 2-R (A range), 5-R (B range), and 8-R (C range). Shifts are synchronized between speeds for on-the-go shifting with the use of the clutch. Shifts between ranges are not synchronized.


Constant-mesh helical gears create excellent reliability and maintain a quiet working environment. Fully enclosed, rigid shift linkages for smooth, crisp shifts enable all operators to clearly know what range and gear in which they are operating.

A positive park pawl on the transmission provides positive park and eliminates the need for a hand brake. This also eliminates clutch service costs that occur when the park brake is accidentally left engaged.

The neutral start switch requires the gear-shift lever to be in either the park or neutral position to start the engine.

A pressure-lubricated top shaft for excellent durability allows the operator to achieve performance from one working season to the next.

I copied and pasted directly from the online 4005 manual. Appears your information is from an advertisement or information brochure.

And, you're right...it is called a "collarshift" (same as the non-synchronized 790/3005), but it seems to be the same transmission from it's predecessor, the 970...and also used in the 4x00/4x10 series machines.

So, BleedGreen...do you have a 4005 or 990? And can you shift between gears without stopping? I only knew one guy with a 990. Never asked him if the transmission was synchronized.

Yep... I finally went on-line and looked the manual up, too. Roy is correct. That's basically the same tranny I had on my 970.

I'll stand with my earlier "analysis" of the pros and cons of a 4005 versus a 3320, however. There's benefits to either machine.

However, a better comparison might be between a 3520 and the 4005. Or possibly the 3320 versus the 4105.

Though I have yet to drive one, I believe that the tranny is a collar shift with the gear stick in the center line of the tractor.
Here are two pics for both 4wd and 2wd.

No...a collarshift is a type of gear transmission. The lever location isn't really relevent (although the collarshift transmission levers I've seen were located as you wrote).
I must admit, it is a bit confusing though...

 

[Ursa Major]

Was just trying to clarify the difference in the layout from the tractors I have seen with those posted earlier showing a side location for the gear and range control sticks. Not sure that was a 4005.
