I really appreciate everyone's advice! Would love to hear more ideas. Another question comes up. I have heard mid-mount mowers are better because they maneuver easier and you can look down and see it to get close to trees, etc. Do you think I would have issues just having a 3-point flail or finish mower?
====================================================================================================
You mean if their better(belly mowers) and don't whack a fence or a tree and have your spouse scream at you for nailing the flower bed?
Your response time wont matter a **** bit, and the mowers arc with the left side or the right with the guard will wake you up quickly.
A Caroni with hydraulic side shift will solve that issue forever and you will be able to mow closer than with a belly mower.
You could use a smaller flail mower with hydraulic side shift and have more than enough power to do everything and not have issues with heavy brush and tall brush as it will sail right through it as the flail mower wil be operating at "full engine power" for the 540 RPM setting and you will have more HP per foot of cut and a trail of shredded mulch.
A flail mower will outlive your old tractor and can be used on the new tractor,
oh and you will not be able to use the old belly mower on the new tractor in most cases.
Not going to happen unless you have a riding mower with a compensating steering system that slows down the tractors forward or reverse direction while turning or has rear steering wheels.
You should read the 93 pages plus on flailmowers then come back and ask questions you do not think were covered in those pages.
A) I am not obcessed with flail mowers, they can and do replace the rotary cutter and finish mower in many cases including my own saving the end user thousands of dollars and retaining thier value.
B) large diamter brush can be redered to dust with a flailmower using both case hardened grass knives and hammer knives as it is done by highway departments with boom mounted flail mowers nationwide and in Europe as well.
C) flailmowers are less work with a balanced cut and thats Just one of many of the plusses for flail mowers.
EDIT
D) you can purchase a front mounted flailmower with hydraulic side shift feeding oil from the front end loader
control valve for your tractor if you have a mid mount PTO as well.
IF you buy a tractor from an out of state reseller you will have to haul or have the unit hauled there in most cases
for warranty work so keep that in mind.
