Looking at used 1850's - its Charlie's fault!

[wasabi]

I had a similar experience on my 1445, when a wheel motor hose blew, rolling backward. If I would have been thinking and not in a panic mode, I could have lowered the bucket for some extra drag. Fortunately, a tree stopped my travel before I was about to go into a large stream.

I do see the need for a shotgun shell powered spike that would be shot into the ground with steel cable to stop the machine in a run-a way situation.

Another way would be to put a electric hyd shut off valve on some or all of the hyd motors, to put them into hyd lock.

ideally an emergency braking system should be automatic. If hyd fails, the unit stops. I wonder if the tender can be acquired separately and fiited to the 2445....wonder the same thing about the tilt seat...

I believe you can make your own system real easy, by using a manual hyd pump, an accumulator, and a check valve, and a release valve. Even without the manual pump, you could design it to charge up the accumulator during normal operation.

Your system does stop automatically doesn't it? Unless your model is older. Mine had a cogged disk which is used a parking brake.

mine has an electric brake but i don't have a lot of confidence in it....mostly i rely on lowered implements...conceptually i'm with you but, with no hyd experience other than repacking a couple of cylinders, i'll need adult supervision...

If any of us had adult supervision our computers would be locked off this site.
I have been entertained by your speculations about making your 2445 into a slope mower. I have a vague recollection that the phones used to be answered at PT mentioning the brake tender as if it were separately marketed. I have no doubt you'd be able to adapt it to your machine, and would like it. JJ's accumulator and other auto brake systems might also work. Then, with new frames, wheel motors and duals, tilt seat and a rough-cut deck, you will have succeeded in creating a slope mower only marginally less capable than an 1845 - and you can leave the backhoe on in case you have to clear some tough stuff out of the way to get to the grass.
Have you considered a used 1850??

glad you are so easily entertained.....absent a really great deal on a used 1850 mower, i'm becoming convinced that ghetto-ing my 2445 with smaller diameter dual wheels might be feasible...

now about the old PT 72" decks. do i understand you and sedge discovered they can accept either rough cut blades or finishing blades? would i need new spindles to accomodate hinged blades and stump jumpers? plan would be to pull the 72" behind and angle-boom a 48" deck out front...

funny thing is when i mentioned converting the 2445 to a slope mower, me wif was dissapointed...said she thought we should find a mower so we had two tractors!

Pt look-a-like on steroids, working hard.

This is what is on my 1445; a pressure line from the aux circuit pressurizes the brake circuit and when something like 600psi is reached, the brakes are released. The electric switch is a solenoid that dumps the pressure from the system.

The Eaton manual for their automatically braked motors mention that you should only apply the brakes when the motors aren't moving. (Can you say hydraulic hammer?) However, in an emergency, I'll take any port in a storm.

All the best,

Peter

hmmm...wet disk brakes...i hate to let too much of my stupidity show, but do these have (possibly worn) brake pads like a car? with elec switch thrown to activate solenoid and vacate pressure, thus allowing brakes to kick in, i still get some creep without implements down. i'll generally use blocks no matter what system, but would like more protection all around so i'm considering retrofitting tender or equiv...

let's see...JJ wants to shotgun a spike into the ground and cable yank a 4,000 lb runaway into submission...you mention accepting any port in a storm and propose slamming the hyd system...

i'm thinkin recycled storm anchor from a sailboat...ya, that's it...hyd hose breaks...crisis mode ensues, but not for the calm and collected...i rip off my custom dust mask, taking care to dislodge and set aside cigar...casually turn around and hurl a 40 plus pound anchor and chain into the weeds...turn back around and grab the cigar, averting potential further drama from launched cigar based brush fire...and brace as the PT rears back like a pit bull againt its choke chain...where is Carl when we need him with cameras rolling for his PT CD's...

Well, you could let er build up speed, riding down the hill to the end of a 50 ft drop off, and then hear your self mutter, Ooooooooh CRAP.

that would be scene one...scene two would be a couple of back woods mechanics trying to figure out how to put proper brakes on the @#$% thing...
