I'm a industrial mowing and vegetation contractor, Specialty Land Management LLC. I'm the current mowing contractor for Entergy for the north half of Louisiana. I manage vegetation clear high lines and fence rows around all power grids and sub stations, I'm certified in Government and Nuclear vegetation management. I have to have equipment that can handle the worst vegetation you can imagine, all my mowers are diesel powered with tractor lugs and 4X4 F3060 and F3680 front cutters, I've been trying to research the Altoz machines since I saw the first TRX track machine.....I finally drove 300 miles to the closest dealer to test the Altoz TRX mower, they didn't have the big 660i so I rode the smallest Track mower he had. I was so impressed I bought 2 of the new TRX 766i sight unseen, I sure I made a good decision, no one checks mower components like I do, it's not like the Kubota machines nor is it tested like the industrial cutters I use and I've tested the best. Slope master has the biggest ZTR cutter around 98 hp diesel!!! $110,000 base price, that will be added to my fleet next year, had to drive to Georga just to look at it. Just because you never heard of it don't make it a bad choice. Most average mowing services can't afford or need machines like we use. So buying expensive machines has to be studied and researched I know what to look for in a machine, the only thing that worries me is....this is the first machine that I have purchased where you can't grease the drive spindles, this is the ONLY drawback I see and ( I hate its it's not diesel) but with regular maintenance it will do!!! Let me know if you have a Altoz machine of any size let me know what you think???
