John Deere Z-Trak Kanzaki Pump

Hey all you Z-Trak guys. Ever had any issues with the double pump/single body Kanzaki pumps? Did it cost an arm and a leg to replace? In general how does everyone feel about these things?

Thanks for your thoughts.

I purchased six ztrak 777's this year and have had all of them in atleast once for new pumps. As well as a few of the loaners we had while the others we being worked on. The pumps were initially going out within 200 hours, after replacements were put in it has been as soon as 25 hours. This design is flawed, and the only suggestion the tech at the dealership has is to run them at half speed up hills to reduce the stress. Each mower does between 10-20 acres a day, half speed is not an option. Until they get rid of the Kanzaki pump I would steer clear of the ztraks.

my first one was a 2004 model after 450 hours, second was a 2006 with 85 hours.... they questioned my problem, but then called back and asked to get it in to fix asap, i later found out they had other calls with the same problem and they just got to it before it got worse.

yes, $650 for the pump, $600 labor, just had one replaced on my new z-trac under warranty, first one wasn't.

1st pump had a "casting burr" fall off, and went through the pump and valves, and destroyed the valve plate, but needed a whole new pump because single parts can't be replaced, just the whole unit.....altough way out of warranty deere paid for the pump, they would've paid for labor but i took it elsewhere.

second machine had a wheel motor go bad, they replaced the pump also, don't know why, don't care, i got a new one.

i wish there were 2 individual pumps, maybe the cost would be less. the new style motors don't even have fans on them, i'm not sold on that idea.

I got 2 757's and have well over 1200 hrs on each with absolutely no pump or drive problems. 647a has had no drive problems with around 500 hrs. The Knazaki pumps do not have to be purchased through a Deere dealer. You can order the pumps and parts direct. Yes, they can be rebuilt. I asked the manufacturer. $600 for labor, I'd take somehwere else, not that long of a job. You are getting soaked.

i haven't had any problems with my stander, as for the pump we called the company, called deere, and they all said no parts, just pumps, if you can show me otherwise, please do so, it will save me money in the future. as for getting soaked, unless your mechanic charges $10 an hour, 40-50 an hour adds up quick. so sit down and figure up hour long it would take to tear a pump out and repalce it, along with draining all the hydro oil, and opening up both wheel motors to be sure there weren't any "burrs" floating around in them too. i haven't met a fast mechanic yet.

i'm glad you haven't had any problems, i am a firm believer in deere equipment, and i see you are too ,but believe it or not, even john deeres break down. somone asked a question, and he got a couple answers, no ones bashing deere or anything, these things happen, what would fertguy have to gain by lying about his breakdowns?

fetguy, all the 757's have had single "stacked" pumps. 2 pumps, same housing. whether these other guys want to hear it or not, yes these machines do break, i had a very simliar problem, as did other local guys. my 2004 model was definietly the better pump of the 2. good luck

I would be glad to give you the info for getting Knazaki parts and pumps. 12 hrs to replace pumps is outrageous. I understand all machines break down but come on, 6 machines at least 1 pump each, plus his loaners. Why do people tell lies, i don't know? I have a right to my opinion.

I am taking delivery of a 777 on thursday. I demoed one for a while along with a 757 and was pleased with the performance of the kanzaki pump. I also did alot of research here on the site on the machines and pretty much found that they dont seem to have alot of negative feedback. Do a search on John Deere 777 and read some of the posts you will be pleased at what you read. I was impressed. Seems like there is always negatives about each machine so you have decide what you want to deal with and what you dont. I put faith in Deere on the hydro system. They have been in business a very long time utilizing hydraulic systems. I am part of a farm family and we also have some of the construction equipment and havent had hydraulic related issues that are alarmingly high relative to other brands. I believe the dual unitized pump system will work fine.

Deere does do there homework and they do make a fine product. But, DeereHauler, you've got it, every piece of equipment has room for improvment.

The root of these issues might have nothing to do with Deere's design and everything to do with Kanzaki quality.

I apreciate all the comments. Keep em comin.
