the older model(ps21-2a)has 265 max torque and this model has 179.does this mean the older model is stronger?

The Model PS22-02 is part of Bosch's new family of brushless tools. Per the manufacturer, benefits of brushless technology are 2x tool life - brushless motor and improved gearbox and electronics mean twice the life of their previous generation.

I don't own this model but I do know that the cheaper models will break if too much torque is applied. As in driving long screws.

Ithink the only other differences are cosmetic. There is a tray/storage in the -2 model below the console that doesn't look like it's there in the earlier model. Honestly though, I think the main value in the extra cost is the improved console. Based on earlier reviews that liked the unit but criticized the console as small and unresponsive, I thought the extra $100 for the newer version would be worth it. The new console is large, nice & informative, and works great.

This torque wrench is rated from 20-200 in-lbs. It's been a while since I last saw the accuracy graph of a torque wrench. But I recall clicking torque wrenches not being as accurate during the first 10-15% of its torque range. So 180 in-lbs should definitely in this wrench's high accuracy range.

From what I read before the motor is stronger in the Elite. The description for the Elite also says this: "New, 2x more powerful motor than original Yonanas". I haven't had an issue with the motor on the regular Yonana so I don't know if it's worth spending the extra money.

3100 psi max on the 6602 as opposed to 3000 psi on the 6412. Also, the low oil and low water cutoff sensors and the associated indicator light have been deleted on the 6602. As of 4/19/14 Amazon's pictures are incorrect and show last years 6412 model.

The biggest difference I noticed immediately was the way it shifted so much more smoothly.. When it comes to power, I didn't really notice too big a difference to justify that being the main reason to buy. Granted you might running 35's as I was only running 31's

The higher the kv the less torque you have but more speed. I hope that helps.

2 is way better. Better response if you ask me they pound and can handle more power. .

they are hard to compare. 231C torques at 600lb while the 231g only torques at 500lb. The 231c has been around for 25 years though. It has a good history. The 231g has a rubber handle while the 231c has a polished handle. The 231c actually says Super Duty. Nothing is mentioned about being super duty on the 231g. Alot of differences in specs. I would call Ingersoll Rand and just ask the differences.Hope this helps.

I have a 51702T which may be last years model and it fits perfect and does have a longer run time.I can't tell a big difference in power but it goes about twice as long on a charge.I use mine as a deck sweeper more than for leaves so I don't have to move stuff off the deck to sweep it with this blower.

I believe it's just an older model number. I haven't found anything with any difference between the two of them.

Hi, not sure what the difference is exactly, but I must admit that I find this one much better than the previous one. It is lighter and more durable so I fully recommend getting 83 slow. Sorry I can't be more of help

Hello John,Thanks for your interest! It has 150ft lbs of torque. We hope that works for you because we would love to get your business.

The 77-1563 advertises a 23.4 lb-ft gain in torque over stock at 3,661 RPM. The 63-1563 advertises a 15.45 lb-ft gain in torque over stock at 4,400 RPM. The 63 produces a 17 hp gain, but at a loftier 4,944 RPM versus the 77 at a 15 hp gain at 4,500 RPM. For 2 less hp, I'll take more torque at lower RPM's.

Hello,The PS-31 is the replacement for the PS-30. The PS-31 is lighter, has slightly higher torque and speed ratings, and slightly improved battery life. Other than that there are some slight design/styling changes but, for the most part, they are fairly similar. That said if I had a choice between the two, I would go with the PS-31.Good Luck!

I've used both, it has more torque at the lower settings but is also heavier and gets hot faster.
