reverse speeds for 990 & geared 3520?

massiveSnow · Jul 2, 2006

Going in reverse very slowly is essential for snow blowing deep show. I am considering the der 990 and gear/power reverse 3520. Does anyone know what the slowest reverse speeds are for these models?

thanks

Per the manual (on the Deere website), the 990 does 1.1 MPH in reverse low range, the 3520 does 0.8 mph in low range reverse.

Both speeds are rated with R-1 tires. R-4's will be different (due to the different circumference of the R-4's) by a couple 100th's MPH.

I've got a 790 with a 2 range tranny. I priced out a 3320 with the power-reverser since the 790's reverse speeds are either too slow or too fast at PTO speed. I wanted the added flexibility of the power-reverser...but since that's the sole reason I was looking, the thought of going into debt for another 5 years didn't appeal to me. However, that power-reverser is one nice transmission!

However, if I were you...I'd go for the 3520 with power-reverser. The 3520 is more money though.
