I have had a 2920 for about 3 years. During the winter, I use it to clear the driveway of snow using the FEL and a rear blade. I don't have chains on the R4 tires, but still never have a problem unless I get a wheel off of the raised rock drive.
I mow our yard some with it using the MMM, but also have a JD garden tractor, so usually use it on the yard. But the MMM does a good job of mowing.
We bought the
B2920 primarily for another 12 acres that we have that is recreational land it is about half woods and half fields. I have a 5' Bush Hog brand mower. A 54" would have probably been a better size, but other than if I have gotten way behind on mowing, it goes through it pretty easily. The negative about using the
B2920 with a rotary mower is the 1/4" valve. You can set the mower at the height you want, but as you mow, it will gradually sink down in the front so you have to bump it up. I now put chains on mine to maintain the height I want. For the other things I do, the 1/4" valve works fine.
For that reason, if you are going to do a lot of cutting with a rotorary mower, you might want to also consider a
B2630 or
B3030. They have some nice features including position control which will hold the mower at the desired height. But they are likely to cost a bit more.
JD has position control on their similar size tractors, but I think they have 2 range HST and I really like the 3 ranges on the
B2920.
All in all, it has been very reliable and makes a great $20K wheel barrow.
