Increasing Width Rear Wheels

Menagerie-Manor · Jul 5, 2021

On my YM2310 it appears as though I can flip the inner rims to gain about 3 or 4 inches of width on each side, am I dreaming or is this doable.

That is the way it was made to work. Turn them around and look carefully at the rims as they are adjustable also. You may need to move them from one side to the other in order to keep the tread in the correct orientation to get the width that you want.

Check in the owners manual and it should have diagrams to show the settings.

Figured as much thanks. If anyone has the actual diagrams that would help as there is minimal info in the aftermarket manual other then keeping the tires in the correct direction.

Below is from a similar US model Yanmar. Might not be exactly like your tractor but should get you the general idea.

Thankyou Hoye Tractor, I can add the page to my Hoye Operators Manual.

That rim looks soooo new, clean and the bolts look very fresh. Is this a UTDA machine?

My tractor had almost flat centers that were welded to the rims... flipping was only worth a couple inches.... would have been nice to have that two piece style

Picked it up from Arizona Tractor about 6 weeks ago, called and spoke to Frederick's and they really were not interested in shipping assistance.

Little grinder work and reweld and any offset you desired is possible

Well at least another 3-4" a side... that said, it would also require removing the tires and tubes from the rims... lotta work and if you want it skinny again, start over....

Reversible wheels on some of the smaller Yanmars, was one of the minor differences between gray (Japan-market) Yanmars and their versions built for the US market.

A prior owner put oversize Kubota rear rims/tires on my YM240 (YM2000). The original Yanmar dished centers match to the Kubota rims.

(Just a note, I don't think Kubota centers have the same bolt spacing as Yanmar axle hubs).

This extra width improves safety on the slopes in my orchard. I also bought the ROPS as soon as Hoye offered them.

Yeah my slopes are a ***** here too, been trying to flail all the perimeter brush for fire safety and it can be a bit unnerving on that terrain. Like the use of the hoist for the wheel removal so I'll break mine out.

Well that was relatively easy to do and we're 14" wider now.

Will the Hoye 4" wheel extenders/spacers fit this tractor. They helped my side to side stability. the attached picture was for a different response but it is also appropriate here.

Hoye has them listed as unavailable at this time but I intend to investigate further.

All you need is a hand-held Bolt Pattern Wheel Template like here:
Trailer Parts Superstore - Bolt Circle Template

I got a FREE Dexter Axle template at an RV trade show a few years back. Simple tool, gives the correct answer every time. Placing it on the lugs or over the bolts scores the pattern every time.

Next, type in a search engine, wheel spacer. See the mountain of hits galore. Off-road, tractors, GMC, Ford, RAM, Tundra, etc, would work for you. HOWEVER, depending on the tractor model, do not exceed 2-inches each side for small SCUTs and no more than 4-inches for CUTs under 35Hp.

The real question should be, what bolts to use, bolt grade and threads per inch. Then a Loctite that will keep things together, but still allow you to take the bolts off when needed.
