 Help on FWD vs. 4WD

Ok, I'm a little confused on some of the manufacturer's drive systems and could really use some help understanding this. The Boomer brochure talks about the optional front wheel drive (FWD) while Kubota talks about four wheel drive (4WD). So does the Boomer really have just a front wheel drive system, or when you engage this are you still driving the rear wheels and essentially getting four wheel drive?
Also, if you have a four wheel drive tractor, is there any disadvantage to running in four wheel drive all of the time, or should you just engage it when you need it?

Thanks.

 Help on FWD vs. 4WD

I am not an expert on Boomers, but the ones I have seen have a standard rear drive axle and a disengageable front axle. In other words itís the same as green and orange.
The only place where keeping the 4wd engaged all the time is likely to cause problems would be on paved surfaces. Most 4wd front tires are set up to run a little faster than the rear tires. If you are operating on soft soil or on snow the extra rpm's dissipate as wheel slippage. If you are on hard surfaces with good traction you are more likely to bind up the drive train.
Most tractors only have brakes on the main (rear) drive wheel. So if you engage the 4wd, and both ends of the tractor are tied together, braking performance, when pulling trailers and such, is greatly enhanced, so much more enhanced that it can make the difference between skidding out of control with the rear wheels locked up and coming to a safe controlled stop.
I find that activating and deactivating the 4wd on my tractor is second nature. When I transition to a paved surface and I do not need the extra braking power of the front axle, I simply kick a lever on the floorboard with my left heel. It is just as easy to engage by stepping on the same lever. You will easily get the hang of it once you start doing it.

On some tractors they do offer differential lock on the front end as well as the rear. That would be a true four wheel drive.

I mow on hills with R4's and the 4wd is the only way to keep the tractor from sliding on even a mild slope. If you want to keep from digging up the ground during slides, you simply keep in 4wd. On steeper slopes in 2wd, there isn't much you can do in a slide except ride it all the way down.

 Help on FWD vs. 4WD

This one had me baffled at first, too. New Holland calls their four wheel drive FWD for some reason. But you can call it 4wd, fwd or whatever, it is the same. As for leaving it in 4wd, I find that my non-SuperSteer equipped TC29 tears the turf in sharp turns when in 4wd, not so much when in 2wd.

 Help on FWD vs. 4WD

I have new TC33D with super steer and AWD/FWD. In the "AWD" mode the front wheels automatically engage into four-wheel-drive mode when they sense slipping compared to the rear wheels; no spilpping and they disengage. This is handy when mowing so it doesn't tear up the lawn when turning. On pavement it doesn't allow the wheels to bind or "jack" when turning (you'll know when it's in FWD 'cause it will leave tire marks on the pavement an indication there is is resistance i.e. tire wear) I was pulling a drag on a large lawn and found that when making sharp turns it tended to engage the the front axle causing unwanted oversteer. If I let off it would correct itself and steer properly.

With only 20 hours on it the starter had to be replaced! And the dealer wants to charge me for a service call to replace it. Anyone had this problem and does NH Customer Service get involved??
