I took delivery of a T4.95 cab, 12x12 PS, 665TL FEL, at the end of January '15. I have not used it enough to comment on its performance. So far, the only issue has been not wanting to shift between gears; linkage adjustment taken care of by the dealer.
The overall cab lay-out I really like and the hi-vis roof panel (sun roof) is a feature most other competitive brands do not offer in this price range. The instrument cluster tilts with the steering wheel so it is always easy to see. Great forward / upward FEL visibility and nice sloping engine hood. The exhaust stack is corner post mounted and does not obstruct the view. The engine seems "torquey" and achieves 540 / 1000 PTO speed at 1900 RPM. The tractor is heavy enough to keep the rear end on the ground with a 5'x5-1/2' round bale raised on a slope - no rear counterweight, no wheel weights or liquid ballast in the Michelin radials.
I did get one of the models made in Jesi, Italy. The current models are made in Ankara, Turkey and there are differences. The Italian tractors have the lever style, pull-up parking brake on the left side of the seat in lieu of the range lever parking pall - one feature that was a must have for me. The power shuttle lever is the same as the T-5 series with the neutral button. Electro-hydraulic rear differential lock. Left rear 3PT side link is adjustable same as the right side.
I will post any major issues and comments on performance will follow.
