Strengths Excellent machine. Easy to operate and maintain. So far, it is the best mower I have ever owned (after retrofit of pump and reservior).

Weaknesses The original ZD21 was a POS. I took it back twice for dealer to check due to limited power in mowing and total performance. Had problems with dealer initially, but when I informed him I would stop payments and advertise what a piece of crap they were selling, he relented. The dealer replaced it with a model that was retrofited with the hydro reservior and pump. ------ That solved the problem totally !!!!! Great machine, I was glad that I choose the ZD21 AFTER the new retrofit model was obtained.

Overall With retrofit, I am very satisfied. ..... Without the retrofit, it was a total piece of crap.

Strengths Engine, controls

Weaknesses Question on Transmission but no indications os any issues so far.

Overall New Owner, used machine and I stumbled over the Arcland post. Local dealer denies any knowledge of retrofit tank On z21. On balance it's a great machine so far. Would like to e-mail arcland to discuss the issue further. JGustafson@wildblue.net

Strengths Engine Compact form Built in jack stand to change blades ergonomics

Weaknesses Transmission Most units will have trans failures around 200-400 hours. Kubota has an after market fix for problem. They have extended the warranty period for older units to four years. Any owner who has the older stlye mower 2006 and earlier should take your unit in to have the auxillary hydro tank installed under the right fender. This keepsthe hydro pump from losing hydro pressure and prolongs the life of the trans. If not installed the unit WILL fail. Any questions you cal e-mail me. Problem with 2006 and earlier models wide spread. Kubot hopes units will age beyond the 4 year extened warranty so they do not have to pay full for warranty service.They will stick you with either 1/2 parts and labor or labor only. Typical trans replacement 3500.00 plus. Buyer beware.

Overall Do not buy a used unit with out knowing if trans has been updated Kubota willnot do anything for once removed owners.

Weaknesses Transmission failure on all zd models

Overall great engine

Strengths A+. I cannot say enough about how good this mower really is. I also have a walk-behind Gravely with a steering sulky and 30" mower, which is a great mower, but this Kubota is absolutely fantastic. I am new to ZTRs, but this mower is so easy to use, I felt right at home the very first time I used it. The guy who delivered the unit from the local dealer showed me how they test these at Kubota. He went so fast, that it scared me. I use the mower with the engine revving just enough to give it power and it goes plenty fast for me. I just love that I need not do much trimming, because I can go right around a tree and then only a little weed eating remains. Kubota's Financing 36 @ 0% makes this professional grade mower affordable for a home owner with a large yard. I also have a Massey 255 which I use to bush-hog about 100 acres, but I wish I could use this Kubota for the 100 acres. In actuality, I probably could, but an 8Ft bush-hog is better than a 60" deck.

Weaknesses I am a Big man who is also handicapped and I wish it had a bigger seat, but otherwise there are no weaknesses which I have been discovered yet.

Overall A+

Strengths This is a great mower. Very happy with my purchase. I choose to run BioDiesel so I'm not breathing regular diesel fumes. Cut's great, easy to use. If you're looking to purchase one of these, you won't be sorry!

Weaknesses None!

Overall

Strengths This IS a MOWING MACHINE! Ease of use was remarkable, even for a first time user. Transitions from low to high speed and back very smoothly. Turning is a breeze. Mows incredibly even and deck is easily accessable to clean. Can't say enough about this machine. It is truly awesome! Financing through kubota was fast and painless. 0.0% for 3 years with nothing down...beat that!

Weaknesses Haven't found one yet. Price was a bit higher than some of the brands we looked at but you get what you pay for...spend the extra money for the kubota.

Overall Has to be the best zero turn mower on the market...hands down. Looked at John Deere, New Holland, Exmark, and Cub Cadet tractors...nothing is comparable to the kubota...nothing.

Strengths The 3 cylinder diesel engine is smooth, quiet, and very strong. Comfortable seat w/armrests, hydrostatic deck-lift and engagement, and shaft-driven, also. The only belt is for the blades. The quality is felt every time the mower is operated. Extremely pleased with my purchase.

Weaknesses None thus far after 200+ hours.

Overall Compared with other diesel Z mowers, it is priced right.

Strengths Cuts through anything without slowing down. Always starts and never has any maintenance problems. Heavy duty construction and will not break.

Weaknesses None

Overall Best Zero turn mower on the market

Strengths Cuts really thick grass doesnt bog down. hydro deck lift comes in handy.

Weaknesses none really

Overall The best mower i have ever ran cant beat it.
