2000 j.d.4200,hst.4x4."150 hrs."Fuel cutoff cyl. bit the dust not long after we brought home our new 4200.15 mounths later,I truely am amazed at this compact tractor.No fluid leaks at all,not one drop on concrete floor.No leaking at steering cyl.Cant make it get hot on a bet!I soo far have done quite a lot of boxblade work.5 ft.5 rippers-rip foward push backwards to make stock pile.Use F.E.L.to move soil over fence to level off yard.I mow about 8 acres with a 513 cutter.HST is smooth enough, in low range smooth as silk.Never has been jerky.Not one loose lug bolt.The batt. will leak juice and make a mess if you let it.I think i would have got the 4300 if i had compared the 2.I am very pleased with this product.If i am ever luckey enough to get another new tractor it will be a J.D.
