    Despite my efforts to have redundant equipment at the ready in case of a break down (or large jump in staff), I had our 2 compactors break down within a day of eachother. This resulted in a hasty purchase of a 3rd compactor, along with ordering 2 Honda power plants for the 2 broken ones. The one I just bought is the Wacker 1550. After using it for a day, I liked the speed, but was very impressed with compaction. With that, I thought I'd comment on the compactors we have, and their strengths and weaknesses. I'd love to hear others with experience with several brands to volunteer their observations, too.

    Our first compactor - a Stone S-28 - 5hp Briggs. Very heavy, and slow travel, but with that speed it's easy to steer. Rated compressive force is around 3,300#, pretty much the same as the rest. Compaction is good.

    Second - Bomag - don't recall the model, but has a 5.5 Honda. Very fast, about 130 pounds. Approximately same rated compaction, and performs as such. One person can lift (with a little effort). Due to speed, a little hard to drive in tight spaces.

    Third - Wacker 1550 - 5.5 Honda. Same rated compaction. Not as fast as the Bomag, but almost. And compaction! There was noticeable increase in difficulty of driving edge restraint spikes into the compacted stone, more difficult to pull pipe, much more difficult to rake out high spots. A little heavier than the Bomag, not as heavy as the Stone. I really didn't think compaction could vary that much given the same size engine, but it can.

    How 'bout the rest of you hardscapers - any experience with different brands of reversible compactors? That's next on my list.

    Stonehenge-Thanks for the info! I'll probably have to use one for a patio I'm doing in a landscape job I've got coming up. It should be a great job to set me off right since it will be my first design/install. Are they fairly easy to operate? I'm not a great precision worker, but I think I could be able to run one.

    Hey Stonehenge,

    I have a 1550 Wacker.. Love it , It moves pretty quickly and does a nice job compacting. It's relatively easy to manuver too. Easy to service and maintain. It weighs in at 180#'s I belive , so you need two people or a loader to move it around. They do offer a wheel kit , but its $200.oo , So I just put it on a furniture dolly..I have used others as rentals and think the wacker is much faster and easier to handle..

    The compactor I run is a smaller SAKAI with a 5.5 hp honda. Its only a 13" plate, but I have been very pleased with it.

    The small plate has been great so far. Excellent for wall work and great for doing things such as stairs. For larger jobs, I rent a wider compactor, but find the small plate adequate for most walks and small patios.

    I'm looking at new ones still, and am deciding between the wacker 1550 like stones, another SAKAI like I have but bigger, or a Dynapac LF90. My local supplier just started carrying the Dynapac and has some good deals on them, so think I may go that way for price. Around here, the wacker is going for around $1600, while the dealer has the dynapac for 1499 and that includes a wheel kit.

    Personally I like the wacker, as most people run them around here. Also, I've had good luck with the Mikasa's, but they are heavy and a little slow.

    I use a Mikasa too, with good results. I bought mine second hand from a blacktopper friend. He had it 5 years prior and I've had it 5 years since. It has a Wisconsin/Robyn 5hp motor that starts first pull at the beginning of every season! My only complaint is the parts for the motor are very expensive.

    I've got a second Mikasa that was given to me that was good for mosquito control (a real smoker) that eventually blew up. I'm planning to replace the motor with a Honda, I figure the parts are more reasonable.

    I'm also interested in the reversable plate compactors, these allow higher gravel lifts to speed the job. I've also considered a vibratory roller for my skid steer, but can't warrant the expense right now.

    Scag - these small plates operate alot like a self-propelled lawnmower. The vibration drives them forward, you just have to steer. The hard part comes when you're compacting very near a structure (like a house), and have little space to maneuver, and a compactor that wants to bolt out of your hands. I've been doing it for awhile and it can still be tricky for me, so I never let my newer guys drive them in tight spaces where they could run it into something.

    When I first started doing hardscapeswhen still in school, the company I worked for used a Mikasa - I remember it compacting well, and being light enough to lift over screed guides while it was running.

    Pelican, I picked up 2 new 5.5 Honda's for $340 apiece from - oh, wait - I may not be allowed to mention who it is. E-mail me and I'll tell you where I ordered them from if you're interested. I run the same engines on my tub saws, so I know I'll get my use out of them one way or another.

    Steveair, how does that 13" plate do vs. some of the wider plates in compaction?

    S-Rex - I thought 180# sounded heavy, so I checked a site with specs - sure enough, the lightest version of the 1550 is 193#. Doesn't seem that heavy.

    I think I met the guy who you bought the engines from.........he was trying to sell me a bobcat with 40 hrs on it for 7k.........seemed like one hell of a deal!

    The 13" plate works just as good as the bigger ones, just takes a little longer. When I first bought it, I was always working by myself and had no machine, so I wanted something I could load and move around by myself.

    I'm very thankful I have it now. Its a great compromise between a larger plate and a jumping jack. I wouldn't get rid of it for the world. And for those tight spaces, it really works well. If you ever see a used one for a reasonable price, I would buy it, as it comes in very handy.

    That's the one thing I never liked is the robin engines. Honda's are much easier to get parts for, and seem to run flawlessy for ever.

    Anyone ever buy a small plate with a diesel engine? Looks like overkill, but I suppose it would be handy for indoor work. Can't say I do enough indoor work though, (well, can't say I do any for that matter) to justify $400 on the upgrade.

    i run (1) Weber VB 50R it has a 5.0 Hp? honda on it and a 20'' plate... compacts 3000LBs about and runs great... can't complain about it yet... also has a water tank on it for soakin down the aggregate first if nec.

    Steveair, I'm not following your thought on the diesel being better for indoor work. Diesels emit CO just as gas engines do and are not suitable for enclosed spaces. Perhaps you are thinking of propane powered machines?

    I've been converting my small equipment to diesel to save trips to the gas station. I have a large diesel tank here and would eventually like all my small equipment to burn #2. I've seen diesel engines as small as 4hp on trash pumps. I just wish someone would put one on a walk behind mower.

    Stonehenge, I'll contact you about the motor, thanks!

    We have moved way from smaller plates, We do have a 1550 and it's a nice finish plate but ..............

    For raw compaction a skid steer with a plate runs circles around plates, our reversable plate is a 24" Wacker, it's slow to move around on site and heavy to turn in tight places, a plate on a skid steer is faster to move, no motors to worry about, covers 66" and frees up a man for grade checking. Plus it beats a roller because it doesn't leave waves in the gravel.
