I've got a bit over a hundred hours on my Branson 4820R now, plus what it had when hauled in, so now around 180+ hours. I've had zero issues to date. I use the tractor daily in the past year as I've been either logging, sawmilling, handling lumber or since spring involved with a personal remote log cabin build that sees the tractor toting materials to the site or most days lifting wall logs for joint cutting or wall placement. Fact is, most days since July it doesn't move but a few feet here or there, other than the materials getting replenished via a modified hay wagon I re-built to haul wall logs to the site. FWIW, it's a 10+ minute tow from my pasture log storage site to the build site.
I did my 50 hour service last year myself, no issues other than took a bit to bleed and fill the Hyd fluid to full. Tractor had like 77 hours of haying only use when I bought it in MO from the original owner.
I did add a grab handle to my tractor to assist with mounting the tractor. I saw a bunch of variations used by others in the Branson FB Group. Several were not ergonomic IMO, a couple were very well done or chosen. One VG one is a Mahindra part that sells for ~ $17 plus SH and tax. I opted to use an Amazon sourced, Warehouse return thats an aftermarket Jeep Grab Handle. Use those terms and you'll see them. My buy I got two with bolts and spacers and they work great! I've included a picture. I used the included long spacers on the left side where I mostly mount, and the short spacers on the right side where the FEL lever is in the way of mounting. I drilled two holes and threaded them and used nuts on the back for increased sturdyness.
I'm currently desiring to find a grab handle for the right fender same as came on my left fender. There are two sets of factory holes plugged on the right fender but I've not found a handle that mates either set? One set if on the fender bend and ~ 6.5" hole centers, the other is up top and the best positioned and ~ 9.5" hole centers. I've searched Amazon and Ebay so far but not seen a perfect fit yet. Ideas are welcome.
Another change I added was a heavier gauge battery tender wire to help properly power my HF diesel -re-fueling pump. It's helpful as much faster * less lifting than pouring, even though the Branson fills down low, whereas my Kioti was up top and a nasty lift job.
That pump is one of the best HF products I've seen! Takes maybe two minutes to suck 5 gallons.
