John Deere Z655

The John Deere Z655 zero turn lawn mower is the biggest of the 2 mowers in the Z600 range from JD, the other mower being the John Deere Z645. The JD Z 655 is actually powered by the same 27 hp engine as it’s little brother. This is an air cooled,twin cylinder engine that has a full pressure lubrication system that has a 1.7 liter oil capacity. The top speed of this machines is also the same as it’s little brother, the JD Z645,  coming in at 14.5 kph (9 mph). Having many of the same attributes, both of these machines may be easily confused. However there is one major difference between the 2.

The John Deere Z655 has a bigger mower deck. The cutting width of the mower deck on the JD Z655 comes in at 54 inches. This mower deck is constructed from very strong 9 gauge steel and is belt driven. The total weight of the machine, with mower deck attached comes to 340 kg (750 lbs). It has a wheelbase of 1.25 m (49 inches) and a length of 1.93 m (76 inches).

The wheels on the John Deere Z655 are fairly large, which makes for a smooth ride as well as it being very unlikely that you will leave thread marks, even if the ground happens to be very soft. The rear wheels each measure 23×10.5-12 (23 inch diameter, 10.5 inch width, 12 inch rim diameter), while the front wheels each measure 13×6.5-6 (13 inch diameter, 6.5 inch width, 6 inch rim diameter). Even if you happen to hit a large obstacle while operating the JD Z655, it’s very unlikely to buckle or break due to the fact that the frame is constructed from heavy duty welded steel.

    I’ve only had this machine for a few months but have found it to be an exceptional piece of equipment. I traded in an 11 year old LX277 and received half of what I paid for it new, plus there was a $300.00 incentive. Having never driven a zero-turn before it is quite a new experience but you’d be suprised how quickly you pick it up. I’ve got 1 1/2 acres to mow of relatively flat property, there are some small hills and it cruises around great. I did get the mulching kit and I’m amazed at how well it does, the clippings just disappear into the lawn. I would highly recommend this machine for anyone with a large lawn, and they want to do it quickly, and have some fun while their at it. Love it, A +++ and +

    Year of Manufacture: 2012
    Pros: Lots of Power
    Great Seating
    Smooth Cut
    Nice Mulching kit
    Fast
    Cons: Gas Gauge is not too easily visable
    Modifications: Mulch Kit

    Excellent. It did have a slight leak at the fitting on the pump as delivered. Dealership picked up and returned within 24 hrs. That is why you don’t buy stuff at big box stores!!
    I didn’t get my lawn rolled before it dried out. However, I was still able to shave about 1hr. off my mow time. I expect after I regrade my yard, it will take even less time as faster speeds will be allowed.
    Multiple safety redundancies built in. Almost too many, but I am sure there is one for every lawsuit they have been through (or would expect).
    Don’t use the wash port!! I have heard this from John Deere and Cub dealers. Think about it for a minute. You’re gonna put cold water on/in a hot bearing. The then moisture will sit there till it cooks out the next time you use it. Stop being lazy and scrap the deck after a mow or two with a wooden spatula. Not to mention, its gonna leave a helluva mess.

    Year of Manufacture: 2011
    Pros: Fast, Quiet, Efficient. Clean and even cut despite slightly bumpy terrain/lawn. Large tires definitely help distribute the weight of the machine and smooth the ride if the lawn has not been rolled. Separate pump and wheel motors operate smoother than the integrated units. Sean is right. Steer clear of the Hydro-Gear EZT units. They are sealed for life but have been prone to leaks. Once they drip dry, they are toast. Supposedly fixed, there have been too many write ups on them. I would have gone with the Z465 but I am even leery of the ZT-2800 (serviceable with one filter per unit). From 2010 to 2011 J.D. switched from the Kanzaki-Dup and Parker Wheel motors to the ZT-2800 in the Z400 series zero turns.
    Cons: Understandably, since this is a new model, not a lot of attachments are available yet. Cannot see fuel level through sight window when operating. J.D. should have either installed a cap with a gauge or located the sight window in a location visible while operating the equipment.
    Attachments: None
    Modifications: None Yet. I run a Purolator Pure One oil filter. The larger filter increases the oil capacity closer to about two quarts. I use 10w-40 Mobil One synthetic high mileage oil. It has higher levels of zinc and should protect the flat tappet cam shaft better. Any high mileage oil or oil for older cars should help in this department.

    was delivered with bad carberator and ran poorly but dealer pick right back up and delivered it 3 days later and it runs great. Needs seat belt as it is fast enough to bounce you off of seat enough to causes mower to start shuting down. Just an FYI skip any mower that has Hydro-Gear EZT drive train as they are junk and will go out aroun 130 hours. ZT2800 or above is ok. to be simple if it doesn’t have an external hydraulic reserve skip it.

    Year of Manufacture: 2011
    Pros: Very fast, Nice cut, Lots of power, 4 year warrenty,Solid machine. Old mower was Cub Cadet what a POS it would take me 2-2.25 hours to cut grass, Now JD Z655 takes 62 minutes and they both had 54″ deck. Hope to get 15+ years off of Z655.
    Cons: needs seat belt
    Attachments: Limited Edition version wich has bumpper,foot ext, and hitch.

    I traded a 2009 Z445 48″ deck for this Z655 w/54HC deck and I think it is a great product. I like the engine being more powerful and more quiet at the same time. And am pretty happy with the size of the machine being 6’4″ it feels like it fits me better than the Z445

    Year of Manufacture: 2011
    Pros: Larger more comfortable seat
    Larger overall body size- not so cramped for larger operator
    Plenty of power
    54HC deck seems to be very well build/heavy gauge steel and plenty of reinforcements
    Hydraulic pumps for motion seem to operate smoother than my old model
    Engine is quieter than old model
    Cons: No bagger option for this model
    Modifications: Headlight kit
    Special edition kit
