Looks very good, glad you finally did it! I didn't think you were going to beat that deal and in essence you have a new tractor.
If this is your trailer that you plan on moving the tractor with I will show you some pics of some simple attaching eyes I installed for the front of my 4520. I suspect something like this will help with the frequent tiedown. For the rear chains I slid the drawbar out and run my chains through the hole in the casting. All the holes are large enough for the chain hooks to pass through too. The front eyes are 1/2 in flat bar bolted to the frame where the grill guard is attached.
I am lost on how to use a bucket ( NEVER owned one ) . All my equipment is 2 hrs from home at cabin . So all I can do for now is play with loader . I get new Big Bee Soil Mover next week !! Then off for a week in April !!! So I get to try it out for real then !!! I have 2 jobs to do , at cabin , plus my own work . I have a HUGE boat dealership parking lot to grade , then a smaller driveway job . The driveway job , needs dirt to be picked up , put in hole ( wash ) then gravel on top . My Ford 3000 could not push dirt backwards enough , so my buddy has had a big hump in his drive ( pile of dirt with gravel over it ) . My plan is to save gravel , pick up dirt , put in hole , then put gravel over dirt ! He is also buying 2 loads of white rock to finish the project . So should be a great day to get use to loader and tractor ! HST is great in tight spots !!
