2084 needs more grunt.
 

One of the primary uses of my 2084 is "tractor" - moving trailers around my wooded hillside lot. It 's just not up to the challenge if the total weight is much over 500 lbs. What can I do to get more power to the wheels?

What about a lower final drive ratio - are they all the same among this generation? I have a 1863 for parts.

Interesting alternative engines?

put smaller tires on it .

At 500 lbs weight behind me my concern wouldn't be power but braking ability. You get into any kind of downhill situation and you won't be pulling the trailer, it will be pushing you. The same can be said about going uphill, if the power fails the trailer will be towing you backwards. You're best, and safest, solution is a bigger, heavier tractor.

I know this all too well! My immediate need was the uphill part.
I figured we could drag it up the incline onto the flat part, then let it back down with the winch.
Ended up using the winch coming and going.

I told my neighbor "We're gonna need a bigger tractor!"

I'd like to have a slightly bigger tractor with an FEL, but my little .87 acre lot doesn't warrant a big tractor.
A few years ago I owned a Cub Loboy, but never had a use for it at the time.

That unit is WAAAY to much weight to be moving around with a Cub Cadet other than on flat, stable ground.
It's liable to get away from you, upset and then you will have a real situation.
I assume it's a rental piece?

Yes, it's a "cherry picker". We had some big dead trees.
Getting up where we it was up a dirt ramp and past a couple trees to level ground - too tight for a pickup to get in.

So we ended up placing the Cub abut 40 feet away and pulling the machine up with my $50 HF winch. It worked a treat. Wish I had taken a photo.

The birds-eye photo is where we towed it out from. Used the tractor hitch and pulled while neighbor worked the trailer brake. The boards you see under the tractor is where the tongue-jack needed to be. We had to re-point it 60 degrees left to get it where the truck could hook up.
(Sorry the photos are not rotated. Not sure how to fix that.)

So yeah, I knew I did not have enough tractor, but we got it done, safely.
