View Full Version : Found a grasshopper 721d for sale looking to buy

I found a nice 721D with about 600 hrs and a 72" deck. What years did they have which transmissions? What years did the deck flip up? What should I look for? I'm new to grasshopper and so is the guy I'm looking to buy it from. Thanks for your time and help.

I was a Grasshopper dealer until I retired and sold my shop. The 721D is way underpowered for the 72" deck That machine has already had a hard life powering that deck.
The 72" deck was never offered in the past with the flip-up option. There was an optional deck lift that would lift up the front of the deck to clear curbs.
That machine, depending on age, could have the older Gemini transmission system, or the newer G2 transmission. I bet it has the Gemini, which has also taked a beating, pushing that big heavy deck around.
The older 72" decks were not all that great. They cut ok, but not great, and were prone to cracking and breaking.
If the deck has what looks exactly like a Grasshopper midmount front caster wheel setup, then it is one of the newer 72" decks, which is a very good deck. Still will not have a flip-up feature though.
If you can buy the machine cheap enough, scrap the 72" deck, and buy a brand new 52" or 61" deck to install on the machine. Then, you will have a flip-up deck that the machine can handle well.

Just checked out your link. Now that is a nice setup at a reasonable price. I wish you were close, I would buy that machine in a heartbeat.

What year did they change 72" decks and the hydro? Thanks

The new style 72" deck, that is really a great design, was offered in 2003, but it may have been available a year or two before that, I am not sure.
The 721D2, with the new style transmission system, was also available by 2003. It may have also been available a year or two earlier, I just do not remember.
Both versions of the 721, (721D with older style Gemini trans. and 721D2 with newer style D2 trans.), have been offered for quite a few years.
The G2 has the individual pumps and wheel motors, while the old Gemini system has the all-in-one trans., one unit for each side.

I didn't buy the grass hopper looking at toro ground master

Be careful about buying a Groundsmaster. Make sure it is not very old. Toro has begun to discontinue parts for anything over 10 years old.

Regarding a somewhat related subject, was the 321D ever offered with a 60" or 61" deck?


04-27-2010, 11:14 PM
Yes, it was offered for many years with the 61" deck, and even a 72" deck was available on it for a few years. I owned 2, with the 61" deck and used them on a large City landfill contract. They lacked a little power in really heavy cutting conditions, so you had to slow down some in thick stuff. In normal conditions, they had plenty of power and lots of torque. Now in my opinion, they were way underpowered with a 72" deck and I would never have bought one with that deck. When I was a dealer, I always told my customers it was best not to spec one with a 72" deck. Grasshopper quickly solved that issue by offering the 428D, which easily handles the 72" deck.
