I've got a
L5030, as has RFB. He has carefully explained every point I would have made, had I gotten here first. I agree with him. I have 200+ acres and it will plow, plant, haul 1500 lb hay bales, lift the 2800 lb hunks of concrete culverts I use as fence posts. In short, I cannot believe that you need anything larger than a 5740HSTC for your 5 acres.
The HST has never even gotten hot on me much less "overheated." I can think of nothing easier for a female to operate than an HST ..... one only presses the clutch when stopped and intending to shift from between Low, Medium, or High gear. Then, the forward/reverse is a continuously variable gearing by rocking your foot back and forth.
I find that the HST is an extreme safety feature.... one can creep forward/back at an inch a minute if you wish to do so... with full power to the wheels at the RPMs selected.
The cab, also, is a serious safety feature... there are handholds on the door that give one a feeling of safety during entry/exit and ease of sitting in the seat when things are a little bouncy (not a replacement for seat belt). The FEL can be managed extremely slowly by resting the elbow on the arm rest and just barely moving the joystick... this just barely moves the FEL... AND control of the FEL is extremely important... the method of elbow-rest manipulation does not rely on strength of shoulder muscles, but rather fine motions of the wrist and arm... something a female can easily do.
Let me put it this way...I spent less than 5 minutes demonstrating to my 26 year old 130lb daughter-in-law how to operate the tractor and she spent the next 2 hours very successfully picking up dumped sand, navigating thru a narrow fence opening, around a tree and placing the sand appropriately in their back yard. Forward gear, backward, throttle control, FEL... she mastered it all and made no mistakes, didn't run over anything, always lowered/raised the FEL at appropriate speed.
Other tractors might well work for you. I KNOW the 5740HSTC will meet your needs for safety, ease of use, function, reliability (over 500 hrs on mine, no failures).
