Looking for a replacement D engine is analogous to finding a needle in the haystack. However there are a lot of Kubota D, D and D engines available both new and remanufactured. Is it possible to swap any of these into the ZD21 mower? Yes, I checked with Kubota and their conservative answer is "the D is the only engine tested for use on the ZD21", but the brochure for the ZD21 also lists the ZD28 and they share a majority of parts. The ZD28 comes with a D Last edited by ejbeaulieu; at PM. I would check the overall dimensions to make sure the new engine will physically fit im the mower, and flywheel connections to make sure the drive line will be compatible, the rest is linkage and such. You can even make adapter plates for the driveline if needed. The question is, is the mower worth the hassle and expense? There you will find dimensioned engine drawings. This should help answer your questions. Looking at the Kubota web site and the service manual, I think I can find a way to make a swap. I may have to replace the mounting brackets but it should fit.

Jun 27, Joined: Jun 19, Messages: 2, The kubota Diesel engine swap by overland diesel has me intrigued for my jeep. You get great fuel mileage, lots of torque, same hp and it is very simple and reliable. Only question I have, and maybe you guys can shed some light on it is, the kubota only revs up to rpm. The L head will go up to rpm or so. I was curious how the lack of rpms would effect my jeeps wheeling ability. Would the added torque make it so I would be able to use a higher gear? My jeep has a T18 and overdrive, so I have 8 gear choices. Lots of times in say mud, 2nd is too low and 3rd doesn't give me enough wheel speed but 2nd od is perfect. I've heard 25mpg. Joined: Jun 5, Messages: 1, I had a small Kubota Tractor, Always amazed how much power the little 4cyl had. It could dig itself right into the ground if tied to immoveable object. Drove right out when you let go. BuildflycrashJun 27, Joined: Sep 21, Messages: 9, You talking about doing that to Ted? GlennJun 27, Joined: Mar 21, Messages: 1, I would think you'd need to go to taller gears in the diff's to compensate for the lack of rpm. Otherwise you would have a pretty low top speed. The kubota diesel would have about the same 60hp that the flathead has. The higher torque is what allows the diesel to make 60 hp at a lower RPM and throught the 0-redline range it will feel significantly stronger than the l-headbut its still the same 60 hp, and will still only be able to push the jeep against the wind with the same amount of force. It will be more efficient and way stronger around town though. Joined: Aug 10, Messages: 20, Right - power is what overcomes drag. Torque gives you acceleration. It would be a fun project. However, I'd think you'd be better off with the VW 1. The Kubota is from a reefer unit or something like that, is it not? Cowboyjeeper likes this.

I'm curious if anyone on this site has done this or is looking into doing it. A few more ponies passed on to the PTO would be ideal when things get thick, wet or unbroken ground. Re: Tweaking Kubota engines for more power? I discovered that the diesel injector pump stop screw had some adjustment range left - it made a noticeable difference in max available power. It was maybe only 10 percent, but it definitely helped get through those spots where it used to bog down. I kept looking at other mods like an aftermarket turbo but there are so many tractor sizes available, it was cheaper to just trade up. Most if not all diesel cars and pickups have common rail diesels that have electrically triggered injectors fed by a single high pressure pump on a single line rail. The ECU controls when they fire, how often they fire, and what the duration is. It also controls rail pressure, so there is a lot that can be tweaked under software usually to the detriment of engine longevity. Unless your Kubota has a similar set up, you are probably pretty much out of luck, except possibly for minor adjustments to the injector pump, such as timing and adjustment of the stop sas already has been suggested, neither or which I would do if it were my engine. Then consider the extra load on the engine, tranny, cooling system, etc that the tractor was not designed for. Unless the injection pump is put in a stand and tested, you really have no idea it you are doing very little or way to much by breaking the seals and playing with it. Buy bigger next time!! Good Luck, Rob. I should have told more of the story - I wasn't flying blind in adjusting my pump. At full fuel the stack didn't smoke at all under load - indicating the stop was set a little lean. I adjusted it until there was a hint of soot unburned fuel at full power. The engine put out a little more power and ran fine for many years after the change. Ya starting jiggering with the factory designed specs. Fellas, The EPA frowns heavily on anyone tampering with the seals on engines these days not from a reliabilty standpoint but for environmental reasons. The new regs apply to off highway engines now where before the farm lobby had enought clout to get a pass. No longer true. You can and will create other problems that can adversely effect your tractor's longevity and reliability to say nothing about your hip pocket. It also can effect warranty coverage as it states in your owner's manuals. A word to the wise. Originally Posted by rbargeron.
