This is not intened to stir you ramon. I hadn't followed this thread till last night when I read the whole thing and the one thing that sticks in my mind even after the endless opinions, suggestions and the like is your comment about your first tractor being (can't remember exactly how you said it) too small/not right and it went back.
It reminded me of the old scenario/comedy skit of a fat woman buying shoes and in the name of vanity insists she wears a size 5 when in reality.....then she blames the salesman, the manufacturer and everyone else that the shoes are defective, mislabled or otherwise not her fault that her feet are now killing her.
Once again I still keep going back to your first tractor experience. Making the mistake once is understandable but twice... I am on my second tractor and if you count various lawn and graden tractors, ATV's etc. each has been a step up in abilty to preform work. I currently have a 7610 and in nine months have probably said many times in my mind "this thing is not enough tractor". Each time I have thought/said it was a stituation where I was expecting more of the machine than it was made to provide. Kubota's fault, the dealer's?....nope -- just mine. I know that if I were to get another machine it would be to accomplish more work, faster than my 7610. Because I am in a 10's of thousands of dollars machine class a step up in abilty to preform work wouldn't be in a 5-10 hp and proportional work load increase but in a 15-25 hp and proportional workload increase. Why? beacuse I now know what one HP of machine provides in this class machine and would understand that the work I was trying to accomplish at a pace I was trying to accomplish it at would require a machine of a much greater size.
Being a two or three time owner now, an owner/operator shoud have a clear understanding of the capability of a particular class/size machine and what size step up is required to accomplish the next level of work.
Once again...not intended to stir or incite just what was still on my mind bewteen last night and this morning.
With kind regards,
Kevin
