Models 749 & 750 have much in common: 

• Professional Honda GX390 engine
• Patented hydro-mechanical clutch
• Large 22” diameter tires
• All-gear-drive to power attachments

The two major differences are:

1. The 750 transmission incorporates special wheel speed reduction gears that result in significantly slower ground speeds than the 749 as illustrated in the following table:

         

Advantage 750:  Because the operating speed of the PTO-driven attachments is determined by the speed of the engine and not the wheels, the consequence is that the implement rotates significantly more times per revolution of the 750 wheels than those of the 749. 

• For example, in low gear the tiller tines of the 750 take 30% more bites per forward foot of travel than those powered by the 749.  Because each tine takes a smaller bite horizontally, the tine can penetrate more deeply on a single pass and often eliminate the need for an extra pass during seedbed preparation.   
• Similarly, if the flail mower is tackling a dense cover crop, the 750 will produce a smaller particle size in a single pass which speeds decomposition.

Advantage 749:  Most applications do not require the extra rotations of the PTO.  Consequently, whether cultivating or mowing in second gear, and definitely when traveling to-and-from the work site in third gear, the additional speed of the 749 saves time and is much appreciated at the end of the day.

2. The 750 has a cast iron rear transmission cover with an integrated, heavy-duty male tang. To see it in action, click here.  In addition, extra steel plating on the transmission allows optional cast iron transmission weights (76lbs) to be added to the transmission housing between the wheel axle and engine.   

Advantage 750: Both of these features are designed to facilitate the use of a super-heavy-duty 33” tiller attachment.  Weighing 180lbs. it is designed exclusively for the 750. (Video Link or Photo Comparing 30” to 33” Tiller Components).  Likewise, these 750 features facilitate the handling of other heavy BCS attachments, most particularly the swivel rotary plow.  Like the tiller, the plow must be lifted when turning at the end of a row, so the counterweights in front of the axle significantly reduce the effort required.

Advantage 749: While the 750 with its 33” tiller is an awesome tool for the landscaper tilling tough, root-bound sod and for the nurseryman infrequently cultivating field stock, it is simply not required for most soil-working applications.  Particularly for the market gardener, the lighter weight of the 749 reduces soil compaction and is easier to maneuver.   

Conclusion: The 749 and 750 are two of twelve different models of BCS two-wheel tractors.  Each model tractor has a slightly different range of appropriate attachments and accessories to meet the particular needs of certain individuals. 

In this case, the model 750 design has clearly been customized/enhanced with the heavy-duty 33” tiller in mind.  In fact, the 33” tiller is the only BCS attachment recommended for just one tractor model!  For most of us, the 749 is the more versatile and appropriate of the two models.  But if you need to consistently and efficiently create seedbeds from really tough soil conditions, the outfit of the 750 tractor with 33” tiller and swivel rotary plow deserves your close consideration.
