So, I want to buy the honda HRC2163HXC commercial unit, right now, I have a 2007 toro proline 21 inch with a Kawasaki 6hp engine, the engine on the honda is 163 cc, this equal about 4,6 hp, my 6hp kawasaki will sometime struggle when the grass is too tall, but it is more powerfull then the honda engine, so, would the honda engine struggle even more? the grass I mow is sometime pretty tall, Can someone that is owning a honda HRC2163HXC commercial tell me if there mower is struggling in tall grass,also, why did honda put a so small hp engine on a commercial unit?

Perhaps for fuel economy in commercial mowing where weekly trims are the norm vs heavy growth? That GXV160 is an excellent engine, though; my sense is that the "commercial" nature of the mower is more about the longevity of the GXV engine and the robustness of the transmission. My 1982 commercial grade HR214 only has a GXV120, and the later HR215 has a GXV140.

If you need more power in a premium residential use, you may want to look at the
HRX217HZA with the GCV200. The next step up for a Honda vertical engine would be the GXV390 in a true commercial machine like the Ferris Honda GXV390 5901736 Walk Behind Mower 32"10.20 HP - SLE Equipment

also, why is the gas tank so small? its a commercial unit, it should have a big gas tank so commercial mower user like me don't have to refuel it all the time,

I just realised something that doesn't make sense, its a 216, so 21 inch and 6hp, but the cc equal at about 4 hp, why?

No, the width is 21" and the 6 just means an engine size (nominal gross HP). Note that the earlier GXV engines were rated at gross HP before the 2007 change to Net HP ratings.

The HR214 had a GXV120 so 4 =118cc = 4.0 HP Gross (2.9 kW) = 3.2 HP Net (2.4 kW) @ 3,600 rpm
The HR215 had a GXV140 so 5 = 135cc = 5.0 HP Gross (3.7 kW) = 4.0 HP Net (3.0 kW) @ 3,600 rpm
The HRC216 has a GXV160 so 6 = 163cc = 4.3 HP Net (3.2 kW) @ 3,600 rpm
The HRX217 has a GCV200 so 7 = 201cc = 5.6 HP Net (4.2kW) @ 3,600 rpm

Honda's Consistent method of rating engine power

Towards a consistent method of rating engine power across all product lines.

As the world's largest engine manufacturer, Honda has decided to apply a consistent method of rating engine power across all product lines; Auto, Motorcycle and Power Equipment; following the notion of ‘Net' power, rather than ‘Gross'. We would like to announce to you that Honda will be the first engine manufacturer to rate all general purpose engines at Net kW (Horsepower) in accordance with the Society of Automotive Engineers (SAE) J1349 test procedure. At the same timing we will also change the way of indicating the torque values (also measured with the ‘Net' setup), fuel consumption (change from g/kW.hr to L/hr) and fuel tank capacity.

Effective for the 2007 model year, Honda kW (HP) specifications for all general purpose engines will be calculated pursuant to SAE J1349 for net power ratings. These net calculations represent changes in the method in which engine power is measured and will result in a change from 2006 published kW (HP) values for individual engine models. Net kW (HP) is calculated with the air cleaner and muffler attached. Gross power calculations are generated without those features. It is important to note that our engines and their power output will be unchanged.

Honda has adopted SAE net power calculations in part as a convenience for the many end users that are buying a product ‘Powered by Honda'. By standardizing our worldwide engine power ratings in accordance with SAE J1349, everybody in the market will enjoy a consistent value for each of our distinct engine models regardless of country of manufacture or sale. The use of this standard will also allow our customers to more easily determine the suitability of an engine for a particular application.

In 2007, Honda will begin to transition all Honda general purpose engines documentation (catalogues, websites, owner's manuals, etc.) to ultimately identify these SAE J1349 ratings where kW (HP) and related values (like torque) are provided.

Honda has always been committed to providing our business partners and customers with the highest quality, most reliable and efficient general purpose engines that we can produce. Since no mechanical changes will be made to our general purpose engine line-up in relation to the SAE J1349 ratings, you and your customers can expect the identical levels of power output, quality, durability and performance that you have come to expect from our engine products.

The power rating of the engine indicated is the net power output tested on a production engine for the engine model and measured in accordance with SAE J1349 at a specified rpm. Mass production engines may vary from this value. Actual power output for the engine installed in the final machine will vary depending on numerous factors, including the operating speed of the engine in application, environmental conditions, maintenance, and other variables.
