Toro 72" Dihatsu 27hp Diesel Review..Finally

    So I have had allot of people send me PM's about how I like my mower and I am sorry I have been way to busy to be on here lately, Now that we haven't had a decent rain in about a month I have time *Sigh* so here we go!

    It has a 27hp Dihatsu Diesel and a 72" Deck I paid about $15,000 after tax.
    It has been a full year now and my feelings are mixed. I have had some problems but they have all been taken care of. I have almost 600hrs on it now. Also remember I mow some insane hills (no joke lots of people say that but I have had other local LCO see me and ask how the heck I do that) and I mow allot of what I call "Industrial accounts" big, rough, and tall lawns, Lots of bouncing and vibrating.


    Fast Fast Fast Fast!!!!!!! This thing scoots!

    The cut is great! I had been getting a bad cut lately but figured out that the deck belt had got so lose my blade pulleys were slipping on the belt. ( In 11 years of mowing I have never had one do this, they always break first)

    Lots of power (on flat Ground we will get in to this in the cons)

    great fuel economy!! I'd say about 1 Gallon a hr


    No power on hills, this thing is a huge heavy tank! On steep hills it sometimes will not make it to the top without stopping and letting the engine catch up. But listen these are real steep hills! But also on very long hills that are moderately steep it will slow down a bit before you get to the top.

    I don't like mule belt setup, It has double belts, they twist them quite a bit and they are very low in the back corners, get sticks and junk in them. I think have put on about 4 or 5 belts

    I had my right wheel motor almost totally disconnect from the machine, The bolts were obviously not tightened properly at the factory

    The welds that hold the brackets for the right fuel tank broke and I lost the tank! They offered to replace the whole frame (due to the fact that the welds were to the frame and made a small rip in part of the frame) I said that was unnecessary. They only had 60" mowers and I would be screwed using a 60" for a week or 2.

    Z-Stand = Useless

    The suspension seat broke at about 500hrs but they replaced it

    I don't like the way they keep the covers on that cover the deck belts, they were out and I have had them off since about 50hrs because they rattled like all get out.

    Air filter intake is on the same side as the grass discharge!!!!! When we check the filter once a week we clean out allot of grass, in dry conditions you have to check it 2 or 3 times a week.

    Had a leak in one of the hydro lines, they replaced

    So all in all here is how I feel.

    If I didn't have a very very good dealer (which I do) it would have got ugly but they took care of it all and I have really not had any major problems after about 200hrs. If you need a very versatile machine to do lots of different things go elsewhere (The 72" 31hp gas engine I think, the gas engine make the machine much much much lighter so in the long run has much more power to weight ratio) If you are looking for a machine to-do lots of big accounts with small to moderate hills this think will make you money! Oh and make sure you have a good dealer!

    Would I do it over? Hmmm.....I think I would look hard at the scag 72" 32hp Turbo Diesel because of the extra power but they are about $2000 more, I would consider the 31hp Toro Gas, It is about $5000 cheaper but you can eat the up fast when it is using twice the gas and it wont have the longevity of the diesel. I guess it all depends on what you need.

    Sorry forgot to mention I also have had to replace the pump drive belt and the water pump belt. Also the pin to set the deck height has a little ball in it the pops up and holds it in place instead of a pin and the little ball falls out after a few hours, I have had 4 of them now and I just gave up.

    What do you mean you have to stop and wait for the motor to catch up on the hills? Have any pics of these hills?

    Thanks for the great review. I plan on making one as soon as I get enough hours on my Hustler. Always nice to have resources like this.

    The rattling has to be from the engine. My 23 Kubota is fantastic.

    I mean the engine will bog out, Even with a 27hp diesel it has tons of torque but the machine is just so dang heavy. I don't have pics but pics never do justice to hills. Besides I'd have all kinds of people telling me I am crazy and gona die. I mow plenty of hills that make your front end float while you go up and that is a big deal considering how big and heavy this deck is.

    No it is the guards because I toke them off and it is fine. The little rubber pieces under the clips wear out, How many hrs on yours and what kind of mowing you do? what size deck? I used a 60" with the 23 kubota and it preforms much better then the 72" with the 27hp Diahatsu because the 60" with the 23hp kubota engine is a much smaller and lighter machine all together

    I have the 31hp on last year's Exmark 66", and I get about .9 hr/gal from it (level ground). I love that engine. I wanted a diesel when I bought it, but the economics just don't support that choice, I think. The deisel engine will outlive the rest of the machine, but what does that get you?

    First that is awesome for a gas engine, But like I said I do allot of hills too and that is a average.

    I'm not so sure the rest of the mower won't last. we have our original exmark and it is still used everyday, it is 12 years old and has well over 5000hrs on it (3000hrs on second engine) we have fixed things but nothing to serious but the engine

    Yep, it's a 60/23 Toro. I have almost 400 hours on it, and I grease the entire machine religiously every 25 hours. It's just the way my route works through the week, 25 hours and the machine is back in mid week. And again at the end of the week. Meaning the guards get pulled at least twice a week. I have no odd rattles. That's what I was getting at. The 72/27 is exactly 225 #'s more than my machine. I am 225#'s myself oddly enough. I don't know what y'all or your crew tip the scales at, but that's not much weight to be making it an anchor. I do notice that your machine has larger pumps, but smaller wheel motors. Which could be a slight problem in the power department on hills. I too get on hills that have rolled other rigs. Not ZTR's, but customers tractors and such. A couple where leaning as far forward is a must. My machine will flinch, but it doesn't bog out uncontrolably. The difference in a naturally aspirated diesel is that the recovery rate isn't as quick on a sharp load. Such as full sticking it, up a hill. If the mower can't pull it at full stick, back off a touch. It's the tradeoff for diesel efficiencly. Your still going faster than 80% of the ZTR's out there. These machines fly in the ground speed department. Just because you can't travel at full stick up a hill doesn't mean there's a problem necessarilly. The height adjustment, yep, take one of the several old pins you have, and drill the detent ball hole all the way through. then tether a hitch pin to it, and stick that through the hole. I been using that with no difficulty or failure since the machine was 4 hours old. I have had both wheel motor hydraulic fittings replaced, they were leaking. I also recently had the front pump lines replaced-(left wheel pump) due to the fact they were leaking. I also had the SAME problem with the wheel motor almost flying off. Except mine was the left side. Tightened the nuts, and all is well. I have a 90 degree gearbox which drives the deck, no crazy belt setup. I have yet to replace a belt. And the gearbox, which was touted on my particular machine as being a possible failure point is holding up fine, has lost nor burnt up any oil, and is as tight as the day I got it. My machine did not come with a suspension seat, or the Z-stand. Both of which I could care less. My dealer tried to sell me a suspension seat for $300, but the factory seat is plenty comfy. I haven't run your particular machine, but I have run one of it's twins/cousins whatever you wanna call it. It seems to be comparable, feel wise, although noticeably larger. I think you have a great machine! FWIW, my 23 burns a calculated .7 GPH. Gotta love that!!! And I burn off road equipment fuel, which I purchase for $2.20/gallon. :clapping: I love it!!! :cool2:

    Wow, glad to see you are so happy. I do a full grease about every 20-30hrs.
    I'm not complaining about not being able to go full stick up the hill, I just wana be able to go up it period. I know what you mean about how to go up the hill but I have tried everything and know what I am doing because I have been doing it a long time (to long it seams sometimes lol)
    As far as the weight I am 260 and are you sure about that weight because I thought my dealer said it was a much bigger difference.
