Hello,all you should need to keep your lower lift arms from hitting your fear tires is those chains with the turnbuckle in them,one end attaches to a connection point on the rear of your tractor and the other end connects through a hole on your lift arms,for a brushog you don't want much side to side movement,mine is adjusted so it only has about a 1/2" slack in each dirrection.You probably don't need much else as far as stablizer bars etc.. The only thing else you should need is a chain to use as top link,just so you can pick up the cutter,top link will do also,but wont give you any[much]up and down on your rear in order to follow ground contour.I have started taking the chain off when I mow and reconnecting it for transport.Set your mower up level[side to side] by using the turn buckle that is on top of your lift arms that go to your hydrolic lift on the back of your tractor.I got my mower set up so the front is about 4" high and the back is about 4 and1/2"high,I'm just cutting grass and light brush.The rear wheel on your mower adjusts up and down.Once you get the height where you want it,you can set your lift control handle [mine has a little block and screw] to where it stops at the same spot every time you lower it.This may help you some,RICHARD GAUTHIER
