Well, I'm gonna find out first hand. I scored a GR2110 circa 2010 with 660hrs on it for $2900. A little rough and neglected perhaps, but everything appears to work as it should. I think a 1/2 day going thru everything, making all the adjustments, changing all fluids and filters and she'll be good to go. Not exactly sure why I bought it, I think I'd really like to see if the blower hitch doesn't interfere with the mower stuff. On the older G-Series I have, removing the mower deck is a PITA. (I did it when I first bought it). Then, when you install the front hitch, it actually bolts to the front and goes under the front axle and bolts again to the frame behind the front axle. WHich means, you have to remove some of the mower deck bracketry as well. It uses the same hydro lift cylinder as the deck, that's why their doing that. So swapping from summer deck to winter blower, would be a real PITA.
I watched a GR2110 promotional video (looked European as the GR in it had the mid deck exit out back to a weird grass catcher not available here in the US), but the deck appears to come off without any tools and rather simply I might add. That would be a huge plus. Basically, I'd like to be able to swap blower to deck without it being a PITA, as your gonna have to do it twice a year. Then I could sell off my older G-Series which is in really good condition and people seem to really want the ones with the rear hydro 3pt and the blower too, and also sell my Benton mower and be well ahead of the game $$$-wise and have one less piece of equipment to maintain.
The first glance at the G-Series to GR major differences, my G-Series has a heavy one piece cast iron rear axle with an access cover. The GR is all alum. two piece sandwich case. While I know a well engineered case can do the job, it just looks spindly. Frame, my G-Series ia heavy two pieces of straight C-CHannel. Rather unengineered. The GR has a plate steel frame with lots of side to side bends and waffles in it. Same deal I guess, a well engineered piece is probably better, but I love the g-series simplicity. The AWD and locked rear is definitely far better than the G-Series. That's a huge plus for when I do wood runs in the back of my property. I've gotten the G tractor buried a couple times back there. The turn radius is alot better on the GR. Power steering is really nice on the GR. The steering system on the older G-Series is a weak point, I replaced the sector gear and all those parts, and that fixes it, but it's just a bad design and it will go bad again, after 2 years it's already loosened up quite a bit. I had a 2nd G-Series which is where I robbed all the hydro 3pt and mid/front lift stuff from and put it on my 5200 and it also had a wrecked steering box.
I dunno, I need to see how much it's gonna cost me to get a blower on this thing. WIthout a blower, I don't really want it. Looking at the diagrams the actual blower piece is really the same as my older G-Series, it's all the little things, the bracketry on the back of the blower, the d-shaft hookup is slightly different, and of course the tractor side hitch it mates to. Also, I do use the small blade on my older G-Series for quick driveway maint, and it uses the same quick hitch deal as the blower, so it's really simple and less than 2 tooless minutes to swap blower to blade. I need to see if a straight blade goes on this tractor without much hassle either. We'll see. Time will tell.
