Ordering and our business

Do you have a store I can visit?

How do I place an order?

Order online any time, or call 877-378-6543, Monday–Friday, 9:00 AM–6:00 PM Central. We're glad to confirm fitment with you before you buy.

How long have you been in business?

OKtractor is family owned and has sold and serviced tractor parts since 2000. We have specialized in Allis-Chalmers from the start and have since added parts and hitches for other makes. We have installed, and even helped design, many of the products we sell.

Parts and fitment

Can you still get parts for Allis-Chalmers tractors?

Yes. Even though Allis-Chalmers has gone through many changes, parts are still available from AGCO and from the aftermarket. We carry new aftermarket parts for the A, B, C, CA, G, RC, WC, WD, WD45 and WF, the D Series (D10–D21), the 100 Series (170–190XT), and the 5000 and 6000 Series. More on our page Can you still get parts for Allis-Chalmers?

How do I know a part fits my tractor?

Each product lists the models it fits and the original part number it replaces. If you're not sure, call us with your model and serial number and we'll check for you.

How do I find my Allis-Chalmers serial number and year?

See our serial number and data pages, for example the WD, WC, D17 and D17 Diesel pages.

3-point hitch conversions

Which 3-point hitch fits my Allis-Chalmers?

It depends on your model and what your tractor has now. There are three main types:

• Drawbar mounted: the strongest option. A mainframe bolts to your existing drawbar (some models need a hole drilled), with positive sway control. Your drawbar stays in place and Traction Booster still works. Higher price, and it is hard-mounted to the tractor.
• Quick (snap-coupler) hitch: the easiest to install. It locks into your snap coupler, needs no drawbar, and Traction Booster still works. Sway control is absent or needs modification, and the drawbar must be removed.
• New-style hitch (WD and WD45 only): like the drawbar-mounted hitch, but the mainframe mounts to the drawbar support brackets.

Do you have hitch conversions for Farmall and John Deere?

Yes. See Farmall/IH 3-point hitch conversions and John Deere 3-point hitch conversions.

What's the difference between Category 0, 1, 2 and 3 hitches?

• Category 0: tractors up to 20 hp. Top link pin 5/8", lift arm pins 5/8".
• Category 1 (most common): 20–45 hp. Top link pin 3/4", lift arm pins 7/8".
• Category 2: 55–95 hp. Top link pin 1", lift arm pins 1-1/8".
• Category 3: above 95 hp. Top link pin 1-1/4", lift arm pins 1-7/16".

Are your hitches made in the USA?

Yes. Our 3-point hitch conversions and most of our rims are made in the USA.

Shipping

How do you ship hitches and rims?

Most parts ship by UPS. Hitches and rims ship unboxed, which meets UPS requirements, because boxes tend to rupture under the weight and odd shapes. UPS handling often scratches the paint and UPS won't insure against it, so if you want a show finish or an exact color match, plan to touch up or repaint.

Do you ship outside the United States?

Shipping outside the US can be difficult, so we handle it by phone only. Please call us at 877-378-6543 to discuss your order.

Returns and policies

What is your return policy?

All returns need authorization first and may have a restocking fee. Some special-order items can't be returned. Once a return is authorized we'll give you the shipping address, which may not be where the item shipped from. Please include a copy of the packing information. Don't send anything back without authorization: manufacturing defects often go back to the manufacturer, and shipping them to us only delays your refund. See Returns & Exchanges.

Do I pay sales tax?

Under our Conditions of Use, any state, local or use taxes are the purchaser's responsibility to pay to the right agency if you're outside Oklahoma.
