Ok, so i am expanding into larger properties and looking to get in commercial the coming year. Have two properties that are 2 acres and 1 commercial along with my residentials. I originally targeted small residentials so i bought a Gravely 34z. Well i love it and cuts awesome. Then i got the first commercial, and now these two homes on the acreage. Well it just takes me forever with the little 34 mostly because 1/2 of these large properties are bumpy uneven ground and i have to slow down or get beaten to death. So the local dealer has a great sale going on some new 2006 models....44, 48, and 54. And with the 1.9% now it seems like the right time to buy in order to expand and be efficient. What are your thoughts on the sizes...i worry about a 54 on the residential yards as people have asked me several times if i use one of those "BIG" mowers and i tell them no at this time. Also, with residentials around here i have a few flower beds to get in between and around, etc. But i know a 54 would make the big places that much easier. I know the logic would be to get the 54, have the 34 and go with that, but i would like to get rid of the 34 and have a bigger 44,48,54 and then a smaller 32 or so WB to get into back yards. The 34z would be quite expensive to have just for occasional use and it has not seen much with all the rain we have been having and i do not want to chance rutting the yards of my nice clients. So the 21 has been seeing a bit of use. OK, i hope that all made sense. Would like to know what you think size wise is good all around and why? Also i dont do a ton of yards so i think a Fasttrack should be ample for me and i think the honda, kohler, or kawi would work fine as i am religious and sometimes overly cautious with maintenance.
