Deutz-Fahr makes a F Ecoline 420 that is 4wd, has a low profile cab and AC, has 96HP and weighs 7012 lbs. It is an orchard/vineyard tractor, so the cab is a little snug. This tractor has 4-wheel hydraulic brakes and front and rear diff locks. It's a light tractor for the HP.
Or go with the larger frame Agrofarm 420 in an open station (no cab) at 99HP and it weighs 7716 without weights. It has a rear three-point lift capacity of 9480 lbs. Also has 4-wheel brakes, front and rear diff locks. This tractor is normally configured with a 20+20 wet clutch power-shift. It puts out 90HP at the PTO per the spec sheet, and we see closer to 95HP-99HP on our PTO dyno...and if you are mowing, it is PTO HP that you care about. Engine HP means little to you. This is a very, very sweet tractor. This tractor can be had with a full size cab or a low profile cab, or open station. Obviously the cabs weigh more. And you will probably want front weights. You can also get an eco PTO, where you run the engine at a lower RPM and still put out 540 at the PTO shaft. That is good if you ever run a smaller mower or are mowing stuff that hardly needs to be mowed. It has other features like a memory RPM setting, you push a button and it goes to a preset RPM.
Deutz-Fahr is imported and sold in the USA via Bavarian Tractor Works. As a low volume distributor of mostly specialty tractors (orchard, vineyard) , one benefit has been that they are able to bring in Tier III tractors for a little while longer. So you get a brand new tractor without the added complication and expense of the Tier IV controls. Quality on these German designed and European built tractors is excellent. They are not cheap, however.
See if you have a dealer nearby. If so, it is worth checking these out.
I do think that Kubota is also a good option. The M108 puts out 96 PTO HP and is not overly heavy. That is a reliable tractor with a huge dealer network.
