the problem is $$$$. It takes just as much time to build a "C52" for example as it does an R72...The difference between cost of engines is very little...no $diff between trans _ tires_ metal etc. Engineering cost would be higher per unit because of lower sales to prorate costs over. Get the picture..problem.. The cost of a product has to include the salary of the worker_engineer_salesmen_serivce techs; utility bill_insurances_ allowances for warr._shrinkage (yes plants do lose things as do grain bins) goof ups (the welder, CNC, etc. misfired) freight, interest, health care for everyone involved and probably a hundred other things I forgot. Oh yeah, a tad of profit for the stockholders..The diff between a 150 hp tractor and a 225 hp tractor is less than $5000 material cost. The companies just make less profit off the low hp unit. Gleaner loses $ or breaks even on every R42 sold. So who would get excited over a low profit low sales new item.......... unless there was a proven market. BTW I guess a few on this site really screwed up the C62 sales because it was supposed to be a higher capacity machine at the same price as a R62..... shhhh
